SELECTED FINANCIAL DATA

This annual report includes our audited consolidated financial statements as of
December 31, 2008 and 2009 and for each of the three years ended December 31, 2007, 2008 and 2009. Our consolidated financial statements have been prepared in accordance with Mexican Financial Reporting Standards (Normas de
Información Financiera Mexicanasor Mexican FRS) and are presented in Mexican pesos. The financial statements of our non-Mexican subsidiaries have been adjusted to conform to Mexican FRS and translated to Mexican pesos. See
Note 2(a)(ii) to our audited consolidated financial statements.

Mexican FRS differs in certain respects from U.S. GAAP.
Note 21 to the audited consolidated financial statements provides a description of the principal differences between Mexican FRS and U.S. GAAP, as they relate to us, a reconciliation to U.S. GAAP of net income and total shareholders
equity and a cash flow statement for the year ended December 31, 2007 under U.S. GAAP.

Under Mexican FRS, our financial
statements for periods ending prior to January 1, 2008 recognized the effects of inflation on financial information. Inflation accounting under Mexican FRS had extensive effects on the presentation of our financial statements through 2007. See
Note 2f to our audited consolidated financial statements.

Beginning with the year ended December 31, 2012, Mexican
issuers with securities listed on a Mexican securities exchange will be required to prepare financial statements in accordance with International Financial Reporting Standards (IFRS) as adopted by the International Accounting Standards
Board (IASB). Issuers may voluntarily report using IFRS before the change in the reporting standards becomes mandatory. We have begun presenting financial statements in accordance with IFRS for the year ended December 31, 2010, with
an official IFRS adoption date as of December 31, 2010 and a transition date to IFRS of January 1, 2009.

On December 13, 2006, our shareholders approved the merger of América Telecom, S.A.B. de C.V., or Amtel, our then
controlling shareholder, and its subsidiary Corporativo Empresarial de Comunicaciones, S.A. de C.V., or Corporativo, with us. As a result of the merger, we assumed assets and liabilities based on Amtels unaudited financial
statements as of October 31, 2006. In accordance with Mexican FRS, the merger with Amtel has been accounted for on a historical basis similar to a pooling of interest basis and we have adjusted our financial information and selected financial
information presented in this annual report to include the consolidated assets, liabilities and results of operations of Amtel for periods presented up to December 31, 2006.

References herein to U.S.$ are to U.S. dollars. References herein to pesos, P. or Ps. are
to Mexican pesos.

This annual report contains translations of various peso amounts into U.S. dollars at specified rates
solely for your convenience. You should not construe these translations as representations by us that the nominal peso or constant peso amounts actually represent the U.S. dollar amounts or could be converted into U.S. dollars at the rate indicated.
Unless otherwise indicated, we have translated U.S. dollar amounts from constant pesos at the exchange rate of Ps. 13.0587 to U.S.$1.00, which was the rate reported by Banco de México for December 31, 2009, as published in the Official
Gazette of the Federation (Diario Oficial de la Federación, or Official Gazette).

|(1) | In accordance with Mexican FRS, the merger with Amtel has been accounted for on a historical basis similar to a pooling of interest basis and we have adjusted our
financial information and selected financial information presented in this annual report to include the consolidated assets, liabilities and results of operations of Amtel for periods presented up to December 31, 2006.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(2) | Except per share, share capital and subscriber data.
|--- | ----------------------------------------------------

|(3) | We have not included earnings or dividends on a per ADS basis. Each L Share ADS represents 20 L Shares and each A Share ADS represents 20 A Shares.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------

|(4) | Nominal amounts. Figures provided represent the annual dividend declared at the general shareholders meeting and for 2005, 2007 and 2009 include special dividends
of Ps. 0.30 per share, Ps. 1.00 per share and Ps. 0.50 per share, respectively.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(5) | Nominal amounts (except for 2009). For more information on dividends paid per share translated into U.S. dollars, see Financial InformationDividends
under Item 8. Amount in U.S. dollars translated at the exchange rate on each of the respective payment dates.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(6) | All L Share figures have been adjusted retroactively to reflect a reduction in L Shares as a result of our merger with Amtel. The increase in AA Shares between 2006 and
2007 was due to the exchange of shares of Amtel for our shares in connection with our merger with Amtel. Subject to certain restrictions, the shareholders of Amtel were free to elect to receive L Shares or AA Shares.

|(7) | The differences between our Mexican FRS and U.S. GAAP operating revenues include the reclassification of (1) the application of ASC 605-50, Customer Payments
and Incentives, which we have applied to all periods presented in this table and which resulted in a reclassification of certain commissions paid to distributors from commercial, administrative and general expenses under Mexican FRS to
reductions in operating revenues under U.S. GAAP, and (2) the application of ASC 605-25, Multiple Element Arrangements, which addresses certain aspects of accounting for sales that involved multiple revenue generating products
and/or services sold under a single contractual agreement. See Note 21 to our audited consolidated financial statements.

|(10) | Notes 2z.1 and 2z.3 to our audited consolidated financial statements describe new accounting pronouncements under Mexican FRS that came into force in 2008 and 2009. The
pronouncements that became effective on January 1, 2008 and 2009, were fully implemented in the financial statements included in this annual report. These new accounting pronouncements were applied on a prospective basis. As a result, the
financial statements of prior years, which are presented for comparative purposes, have not been modified and may not be comparable to our financial statements for 2009.

|(11) | Beginning in 2007, we capitalize interest under Mexican FRS.
|---- | ------------------------------------------------------------

|(12) | Net income and shareholders equity information under U.S. GAAP for prior years were retrospectively adjusted for presentation and disclosure purposes, in
accordance with amendments to Accounting Standards Codification (ASC) 810, Consolidation. ASC 810 states that a non-controlling interest in a subsidiary is an ownership interest in the consolidated entity that should be reported as equity in
the consolidated financial statements, and requires consolidated net income to be reported at amounts that include the amounts attributable to both the parent and the non-controlling interest.
|---- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(13) | Earnings, for this purpose, consist of earnings from continuing operations before income taxes, plus fixed charges and depreciation of capitalized interest and minus
interest capitalized during the period. Through December 31, 2006, for Mexican FRS purposes, employee profit-sharing is considered an income tax and earnings are calculated before the provision for employee profit-sharing. Fixed charges, for
this purpose, consist of interest expense plus interest capitalized during the period. Fixed charges do not take into account gain or loss from monetary position or exchange gain or loss attributable to our indebtedness.

EXCHANGE RATES

Mexico has a free market for foreign exchange, and the Mexican government allows the peso to float freely against the U.S. dollar. There
can be no assurance that the Mexican government will maintain its current policies with regard to the peso or that the peso will not depreciate or appreciate significantly in the future.

The following table sets forth, for the periods indicated, the high, low, average and period-end noon buying rate in New York City for
cable transfers in pesos published by the Federal Reserve Bank of New York, expressed in pesos per U.S. dollar. The rates have not been restated in constant currency units and therefore represent nominal historical figures.

On
May 14, 2010, the noon buying rate was Ps. 12.5820 to U.S.$1.00.

We will pay any cash dividends in pesos, and
exchange rate fluctuations will affect the U.S. dollar amounts received by holders of American Depositary Shares, or ADSs, on conversion by the depositary of cash dividends on the shares represented by such ADSs. Fluctuations in the
exchange rate between the peso and the U.S. dollar affect the U.S. dollar equivalent of the peso price of our shares on the Mexican Stock Exchange (Bolsa Mexicana de Valores, S.A.B. de C.V., or the Mexican Stock
Exchange) and, as a result, can also affect the market price of the ADSs.

FORWARD-LOOKING STATEMENTS

This annual report contains forward-looking statements. We may from time to time make forward-looking statements in our periodic reports
to the U.S. Securities and Exchange Commission, or SEC, on Forms 20-F and 6-K, in our annual report to shareholders, in offering circulars and prospectuses, in press releases and other written materials, and in oral statements made by
our officers, directors or employees to analysts, institutional investors, representatives of the media and others. Examples of such forward-looking statements include:



| |  |  | projections of operating revenues, net income (loss), net income (loss) per share, capital expenditures, dividends, capital structure or other
financial items or ratios;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | statements of our plans, objectives or goals, including those relating to acquisitions, competition, regulation and rates;

| | - |  | ----------------------------------------------------------------------------------------------------------



| |  |  | competitive developments in the telecommunications sector in each of the markets where we currently operate;
| | - |  | ------------------------------------------------------------------------------------------------------------



| |  |  | other factors or trends affecting the telecommunications industry generally and our financial condition in particular; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------



| |  |  | statements of assumptions underlying the foregoing statements.
| | - |  | --------------------------------------------------------------

target, estimate, project, predict, forecast, guideline, should and other similar expressions to identify forward-looking statements, but they are not the only way
we identify such statements.

Forward-looking statements involve inherent risks and uncertainties. We caution you that a
number of important factors could cause actual results to differ materially from the plans, objectives, expectations, estimates and intentions expressed in such forward-looking statements. These factors, some of which are discussed under Risk
Factors, include economic and political conditions and government policies in Mexico, Brazil or elsewhere, inflation rates, exchange rates, regulatory developments, technological improvements, customer demand and competition. We caution you

RISK FACTORS

Risks Relating to Our Businesses

Competition in the wireless industry is intense and could adversely affect the revenues and profitability of our business

Our wireless businesses face substantial competition from other wireless providers. We also face competition from fixed-line
telephone companies and, increasingly, other service providers such as cable, paging, trunking and Internet companies because of the trend towards convergence of telecommunication services.

Competition in our markets has intensified in recent periods, and we expect that it will continue to intensify in the future as a result
of the entry of new competitors, the development of new technologies, products and services, and the auction of additional spectrum. We also expect the current consolidation trend in the wireless industry to continue, as companies respond to the
need for cost reduction and additional spectrum. This trend may result in larger competitors with greater financial, technical, promotional and other resources to compete with our businesses. Telefónica, S.A. (Telefónica
Móviles), which has important operations in Mexico and Brazil, as well as other of our markets, consolidated its position as our largest regional competitor through several acquisitions.

Among other things, our competitors could:



| |  |  | provide increased handset subsidies;
| | - |  | ------------------------------------



| |  |  | offer higher commissions to retailers;
| | - |  | --------------------------------------



| |  |  | provide free airtime or other services (such as Internet access);
| | - |  | -----------------------------------------------------------------



| |  |  | expand their networks faster; or
| | - |  | --------------------------------



| |  |  | develop and deploy improved wireless technologies faster.
| | - |  | ---------------------------------------------------------

Competition can result in increases in advertising and promotional spending and reductions in prices for services and handsets. In
addition, portability requirements, which enable customers to switch wireless providers without changing their wireless numbers, have been introduced in some of our markets, including Mexico and Brazil, and may be introduced in other markets in the
near future.

These developments may lead to smaller operating margins, greater choices for customers, possible consumer
confusion and increasing movement of customers among competitors, which may make it difficult for us to retain customers or add new customers. The cost of adding new customers may also continue to increase, reducing profitability even if customer
growth continues.

Our ability to compete successfully will depend on our coverage, the quality of our network and service,
our rates, customer service, marketing and our ability to anticipate and respond to various competitive factors affecting the telecommunications industry, including new services and technologies, changes in consumer preferences, demographic trends,
economic conditions and discount pricing strategies by competitors. If we are unable to respond to competition and compensate for declining prices by adding new customers, increasing usage and offering new services, our revenues and profitability
could decline.

Changes in government regulation could hurt our businesses

Our businesses are subject to extensive government regulation and can be adversely affected by changes in law, regulation or regulatory
policy. The licensing, construction, operation, sale, resale and interconnection

##### Table of Contents

arrangements of wireless telecommunications systems in Latin America and elsewhere are regulated to varying degrees by government or regulatory authorities. Any of these authorities having
jurisdiction over our businesses could adopt or change regulations or take other actions that could adversely affect our operations. In particular, the regulation of prices that operators may charge for their services could have a material adverse
effect on us by reducing our profit margins.

These risks are significant in all of the markets in which we operate. See
Mexican OperationsRegulation and Non-Mexican OperationsRegulation under Item 4. The risks in our largest markets, for example, include the following.



| |  |  | In Mexico, the business of Radiomóvil Dipsa, S.A. de C.V., or Telcel, is subject to extensive government regulation, principally by
the Mexican Ministry of Communications and Transportation (Secretaría de Comunicaciones y Transportes, or SCT), the Federal Telecommunications Commission (Comisión Federal de Telecomunicaciones, or
Cofetel), the Federal Antitrust Commission (Comisión Federal de Competencia, or Cofeco) and the Federal Consumer Bureau (Procuraduría Federal del Consumidor, or Profeco), and may be
adversely affected by changes in law or by actions of Mexican regulatory authorities. In particular, there has been extensive controversy and dispute in Mexico concerning the interconnection fees payable by local and long-distance operators to
mobile operators. If these disputes are resolved against us, the consequences for our business could be material.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | In Brazil, our business is regulated principally by the Brazilian National Telecommunications Agency (Agência Nacional de
Telecomunicações, or Anatel) and may be adversely affected by its actions or changes in its regulations. In particular, Anatel has defined a series of cost-based methods, including the fully allocated cost methodology,
for determining interconnection fees charged by operators belonging to an economic group with significant market power. Anatel has not published all of the applicable regulations, but the implementation of the cost-based methodology is expected to
take effect during 2010. Anatel published during the first quarter of 2010 a public consultation determining that economic groups with more than 20% of market share will be considered to have significant market power only for purposes of
interconnection fees. Should this proposal be approved, we will be deemed to be an economic group with significant market power, which may affect the results of our Brazilian operations. If approved by Anatel, the effects of the public consultation
will take place during 2010, thus becoming Anatel regulation.

| |  |  | In Colombia, the Colombian Ministry of Information and Communications (Ministerio de Tecnologías de la Información y las
Comunicaciones, or Ministry of Communications) and the Colombian Communications Regulation Commission (Comisión de Regulación de Comunicaciones, or CRC) are responsible for regulating and overseeing
the telecommunications sector, including cellular operations. In September 2009, the CRC issued a series of resolutions stating that Comunicación Celular, S.A. (Comcel), our Colombian subsidiary, has a dominant position in
Colombias market for outgoing mobile services. Under Colombian law, a market participant is considered to have a dominant position in a specified market if the regulators determine that it has the capacity to control the conditions in that
market. The CRC made its determination based on Comcels traffic, revenues and subscriber base. The resolutions also included regulations that would require Comcel to charge rates (excluding access fees) for mobile-to-mobile calls outside the
Comcel network (off net) that are no higher than the fees charged for mobile-to-mobile calls within the Comcel network (on net) plus access fees. The regulations were first implemented on December 4, 2009. These
regulations will limit Comcels flexibility in offering pricing plans to its customers, but we cannot predict the effects on its financial performance. See Legal ProceedingsComcel Dominant Position under Item 8.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In addition, changes in political administrations could lead to the adoption of policies concerning
competition and taxation of communications services that may be detrimental to our operations throughout Latin America. These restrictions, which may take the form of preferences for local over foreign ownership of communications licenses and
assets, or for government over private ownership, may make it impossible for us to

##### Table of Contents

continue to develop our businesses. These restrictions could result in our incurring losses of revenues and require capital investments all of which could materially adversely affect our
businesses and results of operations.

Dominant carrier regulations could hurt our business by limiting our ability to
pursue competitive and profitable strategies

Cofetel is authorized to impose specific requirements as to rates,
service quality and information on any wireless operator that is determined by Cofeco to have substantial market power in a specific market. In two investigations, Cofeco has issued resolutions concluding that Telcel has substantial market power in
the national mobile telephone services relevant market. Under the Antitrust Law (Ley Federal de Competencia Económica) and the Telecommunications Law (Ley Federal de Telecomunicaciones), if Cofeco makes a final finding of
substantial market power concerning an operator, Cofetel can impose on that operator specific regulations with respect to tariffs, quality of service and information. We cannot predict what regulatory steps Cofetel might take in response to
determinations by Cofeco. We believe that if dominant carrier regulations are imposed on our business in the future, they will likely reduce our flexibility to adopt competitive market policies and impose specific tariff requirements or other
special regulations on us, such as additional requirements regarding disclosure of information or quality of service. Any such new regulation could have a material adverse effect on our operations.

Cofeco is also conducting four investigations into whether Telcel has engaged in monopolistic practices. Adverse determinations against
Telcel in any of the ongoing investigations could also result in material fines, penalties or restrictions on our operations.

We will, in the future, have to acquire additional radio spectrum capacity in order to expand our customer base and maintain the
quality of our services

Licensed radio spectrum is essential to our growth and the quality of our services,
particularly for GSM and UMTS services and increased deployment of 3G networks to offer value-added services. We can increase the density of our network, thus reducing our need for additional spectrum by building more cell and switch sites, but such
measures are costly and would be subject to local restrictions and approvals, and they will not fully meet our needs.

In
2005, we acquired the right to use 10 megahertz in the 1900 megahertz spectrum in each of Mexicos nine regions, through a public auction. We also bid and won the auction for an additional 10 megahertz of capacity in three principal regions,
but were subsequently prohibited from acquiring this additional spectrum based on restrictions imposed by Cofeco. On January 6, 2010, Cofetel published conditions for spectrum auctions. In April 2010, both Cofetel and Cofeco authorized
Telcels participation in the aforesaid auctions.

Participation in spectrum auctions requires prior governmental
authorization (including prior approval from Cofeco).

Our concessions and licenses are for fixed terms, and conditions
may be imposed on their renewal

Our concessions and licenses have specified terms, ranging typically from 10 to 30
years, and are generally subject to renewal upon payment of a fee, but renewal is not assured. The loss of, or failure to renew, any one concession could have a material adverse effect on our business and results of operations. Our ability to renew
concessions and the terms of renewal are subject to a number of factors beyond our control, including the prevalent regulatory and political environment at the time of renewal. Fees are typically established at the time of renewal. As a condition
for renewal, we may be required to agree to new and stricter terms and service requirements. If our concessions are not renewed, we are required to transfer the assets covered by the concession to the government, generally for fair market value,
although certain jurisdictions provide for other valuation methodologies.

##### Table of Contents

In Mexico, the Mexican Telecommunications Law also gives certain rights to the Mexican
government, including the right to revoke the concessions pursuant to an expropriation or to take over the management of Telcels networks, facilities and personnel in cases of imminent danger to national security, internal peace or the
national economy, natural disasters and public unrest.

We continue to look for investment opportunities, and any future
acquisitions and related financings could have a material effect on our business, results of operations and financial condition

We continue to look for other investment opportunities in telecommunication companies worldwide, primarily in Latin America and the
Caribbean, including in markets where we are already present, and we often have several possible acquisitions under consideration. For example, we may pursue further market consolidation opportunities in Argentina and Brazil depending on their terms
and conditions. Any future acquisitions and related financings could have a material effect on our business, results of operations and financial condition, but we cannot give any assurances that we will complete any of them. In addition, we may
incur significant costs and expenses as we integrate these companies in our systems, controls and networks.

We may be
unsuccessful in addressing the challenges and risks presented by our investments in countries outside Mexico

We have
invested in a growing number of telecommunications businesses outside our historical activity of providing wireless telecommunications services in Mexico, and we plan to continue to do so in the rest of Latin America and the Caribbean. Whereas
Mexico accounted for 63.0% of our total wireless subscribers as of December 31, 2002 and 71% of our consolidated revenues during 2002, it accounted for 29.4% of our total wireless subscribers as of December 31, 2009 and 36.1% of our
consolidated revenues during 2009. During that period, Brazil, as a result of rapid subscriber growth and the acquisitions of BSE S.A. and BCP S.A. (now Claro S.A.), increased its share of our total wireless subscribers from 16.3% as of
December 31, 2002 to 22.1% as of December 31, 2009, and it accounted for 20.6% of our consolidated revenues during 2009. These investments outside Mexico may involve risks to which we have not previously been exposed. Some of the
investments are in countries that may present different or greater risks, including from competition, than Mexico. We cannot assure you that these investments will be successful.

We are subject to significant litigation

Some of our subsidiaries are subject to significant litigation, which if determined adversely to our interests may have a material adverse
effect on our business, results of operations, financial condition or prospects. In Mexico, for example, there are pending administrative investigations into whether Telcel has substantial market power and whether it has engaged in monopolistic
practices, and there are legal proceedings regarding rates for interconnection with other operators. In Brazil, there are pending regulatory proceedings regarding the calculation of inflation-related adjustments due under our concessions with
Anatel. In Colombia, there are administrative proceedings against Comcel regarding alleged anti-competitive behavior. Our significant litigation is described in Legal Proceedings under Item 8.

A system failure could cause delays or interruptions of service, which could cause us to lose customers and revenues

We will need to continue to provide our subscribers with reliable service over our network. Some of the risks to our
network and infrastructure include the following:



| |  |  | physical damage to access lines;
| | - |  | --------------------------------



| |  |  | power surges or outages;
| | - |  | ------------------------



| |  |  | limitations on the use of our radiobases;
| | - |  | -----------------------------------------

##### Table of Contents

| |  |  | software defects;
| | - |  | -----------------



| |  |  | natural disasters; and
| | - |  | ----------------------



| |  |  | disruptions beyond our control.
| | - |  | -------------------------------

Disruptions may cause interruptions in service or reduced capacity for customers, either of which could cause us to lose subscribers and
incur additional expenses.

If our current churn rate increases, our business could be negatively affected

The cost of acquiring a new subscriber is much higher than the cost of maintaining an existing subscriber.
Accordingly, subscriber deactivations, or churn, could have a material negative impact on our operating income, even if we are able to obtain one new subscriber for each lost subscriber. Because a substantial majority of our subscribers
are prepaid, we do not have long-term contracts with those subscribers. Our weighted monthly average churn rate on a consolidated basis for the twelve-month period ended December 31, 2008 was 2.8% and for the twelve-month period ended
December 31, 2009 was 3.0%. If we experience an increase in our churn rate, our ability to achieve revenue growth could be materially impaired. In addition, a decline in general economic conditions could lead to an increase in churn,
particularly among our prepaid subscribers.

We depend on key suppliers and vendors to provide equipment that we need to
operate our business

We depend upon various key suppliers and vendors, including Apple, Nokia, Research in Motion
(RIM), Sony-Ericsson, Huawei, Motorola, LG and Samsung, to provide us with handsets and network equipment, which we need to operate our business. If these suppliers or vendors fail to provide equipment or service to us on a timely basis, we
could experience disruptions, which could have an adverse effect on our revenues and results of operations. In addition, we might be unable to satisfy the requirements contained on our concessions.

Our ability to pay dividends and repay debt depends on our subsidiaries ability to transfer income and dividends to us

We are a holding company with no significant assets other than the shares of our subsidiaries and our holdings of cash
and marketable securities. Our ability to pay dividends and repay debt depends on the continued transfer to us of dividends and other income from our subsidiaries. The ability of our subsidiaries to pay dividends and make other transfers to us may
be limited by various regulatory, contractual and legal constraints that affect our subsidiaries.

Failure to acquire a
substantial majority of the outstanding capital stock of Telmex Internacional through the ongoing exchange offers for shares of Telmex Internacional and Carso Global Telecom would affect our ability to complete any post-closing changes in the
corporate structure of the combined company, which could reduce or delay the cost savings or revenue benefits to the combined company

On May 11, 2010, we commenced two separate but concurrent offers to acquire outstanding shares of Telmex Internacional, S.A.B. de
C.V. (Telmex Internacional) and Carso Global Telecom, S.A.B. de C.V. (CGT). Unless they are extended, the offers are scheduled to expire on June 10, 2010. Consummation of the offer to acquire shares of Telmex
Internacional is not conditioned on participation by a minimum number of shares of Telmex Internacional. In addition, pursuant to Mexican law, we will not be in a position to cause the delisting of such shares from the Mexican Stock Exchange and
deregistration of such shares from the Mexican National Banking and Securities Commission (Comisión Nacional Bancaria y de Valores, or CNBV) unless, among other things, we obtain at least 95% of the issued and outstanding
shares of Telmex Internacional (the level of shareholder approval required for delisting and deregistration under Mexican law). If we acquire less than 100% of the outstanding shares of Telmex Internacional, the existence of minority shareholders at
Telmex Internacional, and the continuing listing and registration of Telmex Internacional may generate additional



11

##### Table of Contents

expenses and result in administrative inefficiencies. We may also be required to maintain separate audit and corporate practices committees at the boards of directors of América
Móvil and Telmex Internacional, and we may be subject to separate reporting requirements with the Mexican Stock Exchange. In addition, all transactions between Telmex Internacional and us could be subject to additional requirements under
Mexican law, which may limit our ability to achieve certain savings and to conduct the joint operations as a single business unit in order to achieve our strategic objectives, such as effecting certain changes in the corporate structure of Telmex
Internacional and its subsidiaries that could result in significant benefits to the combined company. As a result, it may take longer and be more difficult to effect any post-closing changes in corporate structure and the full amount of the cost
synergies and revenue benefits for the combined company may not be obtained or may only be obtained over a longer period of time. This may adversely affect our ability to achieve the expected amount of cost synergies and revenue benefits after the
offer to acquire outstanding shares of Telmex Internacional is completed.

If we complete the ongoing exchange offers
for shares of Telmex Internacional and CGT, we may fail to realize the business growth opportunities, revenue benefits, cost savings and other benefits anticipated from, or may incur unanticipated costs associated with, the offers and our results of
operations, financial condition and the price of our shares may suffer

Our acquisition of Telmex Internacional may not
achieve the business growth opportunities, revenue benefits, cost savings and other benefits we anticipate. We believe the offer consideration is justified by these benefits we expect to achieve by combining our operations with those of Telmex
Internacional. However, these benefits may not develop and other assumptions upon which the offer consideration was determined may prove to be incorrect, as, among other things, such assumptions were based on publicly available information.

We may be unable to fully implement our business plans and strategies for the combined businesses due to regulatory
limitations. Each of América Móvil and Telmex Internacional is subject to extensive government regulation, and we may face regulatory restrictions in our provision of combined services in some of the countries in which we operate. For
example, in Brazil, América Móvils and Telmex Internacionals businesses are regulated by Anatel. Pending regulations by Anatel, which focus on economic groups with significant market powers, will impose new cost-based
methodologies for determining interconnection fees charged by operators in Brazil. We cannot predict whether Anatel would impose specific regulations that would affect our combined operations more adversely than they would affect our individual
operations. In Mexico, Telcel is part of an industry-wide investigation by Cofeco to determine whether any operators possess substantial market power or engage in certain monopolistic practices in certain segments of the Mexican telecommunications
market. CGT is the direct holder of approximately 59.4% of the outstanding capital stock of Teléfonos de Mexico, S.A.B. de C.V. (Telmex), and we will be acquiring a controlling interest in Telmex through the offer to acquire
outstanding shares of CGT. As a result of those investigations, Telmex and Telcel have already been found to have substantial power in certain markets. We cannot predict whether Cofeco or other governmental entities would renew or revise its
investigations to take into account the combined businesses.

Under any of these circumstances, the business growth
opportunities, revenue benefits, cost savings and other benefits anticipated by us to result from the exchange offers may not be achieved as expected, or at all, or may be delayed. To the extent that we incur higher integration costs or achieve
lower revenue benefits or fewer cost savings than expected, our results of operations and financial condition may suffer.

Our consolidated indebtedness will increase substantially if we complete the ongoing exchange offers for shares of Telmex
Internacional and CGT

Our consolidated indebtedness will increase as a result of the ongoing exchange offers for
shares of Telmex Internacional and CGT. As of December 31, 2009, we had, on an unconsolidated basis (parent company only), unsecured and unsubordinated indebtedness and guarantees of subsidiary indebtedness of approximately



12



---

##### Table of Contents

Ps. 99,316 million (U.S.$7,605 million). In addition, each of Telmex Internacional, CGT and Telmex has substantial consolidated indebtedness which will be consolidated in our financial
statements for future periods with our consolidated indebtedness if the exchange offers are completed.

Completing the
offer to acquire outstanding shares of Telmex Internacional could require a substantial expenditure of cash

If all
shareholders of Telmex Internacional other than CGT participate in the offer to acquire outstanding shares of Telmex Internacional and elect to receive the cash consideration, we will be required to pay approximately Ps. 82,495 million
(U.S.$6,669 million based on the April 30, 2010 exchange rate). At current market prices, the value of the cash consideration exceeds the value of the share consideration. So we expect many shareholders to elect cash consideration, although
these conditions may change before the expiration of the offer to acquire outstanding shares of Telmex Internacional.

Risks Relating to
the Wireless Industry Generally

Changes in the wireless industry could affect our future financial performance

The wireless communications industry is experiencing significant changes as new technologies are developed that offer
subscribers an array of choices for their communications needs. These changes include, among others, regulatory changes, evolving industry standards, ongoing improvements in the capacity and quality of digital technology, shorter development cycles
for new products, and changes in end-user needs and preferences. In Mexico and in the other countries in which we conduct business, there is uncertainty as to the pace and extent of growth in subscriber demand, and as to the extent to which prices
for airtime and line rental may continue to decline. If we are unable to meet future advances in competing technologies on a timely basis or at an acceptable cost, we could lose subscribers to our competitors. In general, the development of new
services in our industry requires us to anticipate and respond to the varied and continually changing demands of our subscribers. We may not be able to accurately predict technological trends or the success of new services in the market. In
addition, there could be legal or regulatory restraints to our introduction of new services. If these services fail to gain acceptance in the marketplace, or if costs associated with implementation and completion of the introduction of these
services materially increase, our ability to retain and attract subscribers could be adversely affected.

There are four
existing digital technologies for wireless communications, none of which is compatible with the others except for long term evolution (LTE), which is compatible with global system for mobile communications (GSM). In the past, Telcel and certain of
our international businesses used time division multiple access (TDMA) technology for their digital networks, while certain of our other international businesses used code division multiple access (CDMA) as their digital wireless technology. We have
introduced GSM technology in all of our markets (excluding TracFone Wireless, Inc.). Also, Telcel and all of our international businesses (excluding Tracfone Wireless, Inc.) launched new networks using the UMTS and HSDPA third generation technology
between 2007 and 2009. We expect to complete the deployment of the third generation technology in the following years. If future wireless technologies that gain widespread acceptance are not compatible with the technologies we use, we may be
required to make capital expenditures in excess of our current forecasts in order to upgrade and replace our technology and infrastructure.

The intellectual property rights utilized by us, our suppliers or service providers may infringe on intellectual property rights
owned by others

Some of our products and services use intellectual property that we own or license from others. We
also provide content services we receive from content distributors, such as ring tones, text games, video games, wallpapers or screensavers, and outsource services to service providers, including billing and customer care



13

##### Table of Contents

functions, that incorporate or utilize intellectual property. We and some of our suppliers, content distributors and service providers have received, and may receive in the future, assertions and
claims from third parties that the products or software utilized by us or our suppliers, content distributors and service providers infringe on the patents or other intellectual property rights of these third parties. These claims could require us
or an infringing supplier, content distributor or service provider to cease engaging in certain activities, including selling, offering and providing the relevant products and services. Such claims and assertions also could subject us to costly
litigation and significant liabilities for damages or royalty payments, or require us to cease certain activities or to cease selling certain products and services.

We may incur significant losses from wireless fraud and from our failure to successfully manage collections

Our wireless businesses incur losses and costs associated with the unauthorized use of these wireless networks, particularly their analog
cellular networks. These costs include administrative and capital costs associated with detecting, monitoring and reducing the incidence of fraud. Fraud also affects interconnection costs, capacity costs, administrative costs and payments to other
carriers for unbillable fraudulent roaming.Although we seek to combat this problem through the deployment of anti-fraud technologies and other measures, we cannot assure you that these efforts will be effective or that fraud will not result
in material costs for us in the future.

Cloning, which is one form of wireless fraud, involves the use of scanners and other
electronic devices to obtain illegally telephone numbers and electronic serial numbers during cellular transmission. Stolen telephone and serial number combinations can be programmed into a cellular phone and used to obtain improper access to
cellular networks. Roaming fraud occurs when a phone programmed with a number stolen from one of our subscribers is used to place fraudulent calls from another carriers market, resulting in a roaming fee charged to us that cannot be collected
from the subscriber.

Concerns about health risks relating to the use of wireless handsets and base stations may
adversely affect our business

Portable communications devices have been alleged to pose health risks, including
cancer, due to radio frequency emissions from these devices. Lawsuits have been filed in the United States against certain participants in the wireless industry alleging various adverse health consequences as a result of wireless phone usage, and
our businesses may be subject to similar litigation in the future. Research and studies are ongoing, and there can be no assurance that further research and studies will not demonstrate a link between radio frequency emissions and health concerns.
Any negative findings in these studies could adversely affect the use of wireless handsets and, as a result, our future financial performance.

Developments in the telecommunications sector have resulted, and may in the future result, in substantial write-downs of the
carrying value of certain of our assets

We review on a annual basis, or more frequently where the circumstances
require, the value of each of our assets and subsidiaries, to assess whether those carrying values can be supported by the future cash flows expected to be derived from such assets. Whenever we consider that due to changes in the economic,
regulatory, business or political environment, our goodwill, intangible assets or fixed assets may be impaired, we consider the necessity of performing certain valuation tests, which may result in impairment charges. The recognition of impairments
of tangible, intangible and financial assets results in a non-cash charge on the income statement, which could adversely affect our results of operations. For example, during 2007 and 2008, we recorded charges in respect of certain analog, TDMA and
CDMA equipment in Argentina, Brazil, Colombia and Ecuador following our decision to discontinue using the equipment.

Risks Relating to Our Controlling Shareholders, Capital Structure and Transactions with Affiliates

Members of one family may be deemed to control us

According to reports of beneficial ownership of our shares filed with the SEC, Carlos Slim Helú, together with his sons and
daughters (together, the Slim Family), including his son and chairman of our board of directors, Patrick Slim Domit, may be deemed to control us. The Slim Family may be able to elect a majority of the members of our board of directors
and to determine the outcome of other actions requiring a vote of our shareholders, except in very limited cases that require a vote of the holders of L Shares. We cannot assure you that the Slim Family will not take actions that are inconsistent
with your interests.

We have significant transactions with affiliates

We engage in transactions with Telmex, Telmex Internacional, and certain of their subsidiaries and with certain subsidiaries of Grupo
Carso, S.A.B. de C.V. and Grupo Financiero Inbursa, S.A.B. de C.V., all of which are affiliates of América Móvil. Many of these transactions occur in the ordinary course of business and, in the case of transactions with Telmex, are
subject to applicable telecommunications regulations in Mexico. Transactions with affiliates may create the potential for conflicts of interest.

We also make investments together with affiliated companies, sell our investments to related parties and buy investments from related
parties. We may pursue joint investments in the telecommunications industry with Telmex and Telmex Internacional. For more information about our transactions with affiliates see Related Party Transactions under Item 7.

Our bylaws restrict transfers of shares in some circumstances

Our bylaws provide that any acquisition or transfer of more than 10% of our capital stock by any person or group of persons acting
together requires the approval of our Board of Directors. If you acquire or transfer more than 10% of our capital stock, you will not be able to do so without the approval of our Board of Directors.

The protections afforded to minority shareholders in Mexico are different from those in the United States

Under Mexican law, the protections afforded to minority shareholders are different from those in the United States. In particular, the law
concerning fiduciary duties of directors is not as fully developed as in other jurisdictions, there is no procedure for class actions, and there are different procedural requirements for bringing shareholder lawsuits. As a result, in practice it may
be more difficult for minority shareholders of América Móvil to enforce their rights against us or our directors or controlling shareholder than it would be for shareholders of a company incorporated in another jurisdiction, such as
the United States.

Holders of L Shares and L Share ADSs have limited voting rights, and holders of ADSs may
vote only through the depositary

Our bylaws provide that holders of L Shares are not permitted to vote except on
such limited matters as, among others, the transformation or merger of América Móvil or the cancellation of registration of the L Shares with the National Securities Registry (Registro Nacional de Valores, or
RNV) maintained by CNBV or any stock exchange on which they are listed. If you hold L Shares or L Share ADSs, you will not be able to vote on most matters, including the declaration of dividends, that are subject to a
shareholder vote in accordance with our bylaws.

Holders of ADSs are not entitled to attend shareholders meetings,
and they may only vote through the depositary

Under our bylaws, a shareholder is required to deposit its shares with a
custodian in order to attend a shareholders meeting. A holder of ADSs will not be able to meet this requirement, and accordingly is not



15



---

##### Table of Contents

entitled to attend shareholders meetings. A holder of ADSs is entitled to instruct the depositary as to how to vote the shares represented by ADSs, in accordance with procedures provided
for in the deposit agreements, but a holder of ADSs will not be able to vote its shares directly at a shareholders meeting or to appoint a proxy to do so.

Mexican law and our bylaws restrict the ability of non-Mexican shareholders to invoke the protection of their governments with
respect to their rights as shareholders

As required by Mexican law, our bylaws provide that non-Mexican shareholders
shall be considered as Mexicans in respect of their ownership interests in América Móvil and shall be deemed to have agreed not to invoke the protection of their governments in certain circumstances. Under this provision, a non-Mexican
shareholder is deemed to have agreed not to invoke the protection of his own government by asking such government to interpose a diplomatic claim against the Mexican government with respect to the shareholders rights as a shareholder, but is
not deemed to have waived any other rights it may have, including any rights under the U.S. securities laws, with respect to its investment in América Móvil. If you invoke such governmental protection in violation of this provision,
your shares could be forfeited to the Mexican government.

Our bylaws may only be enforced in Mexico

Our bylaws provide that legal actions relating to the execution, interpretation or performance of the bylaws may be brought only in
Mexican courts. As a result, it may be difficult for non-Mexican shareholders to enforce their shareholder rights pursuant to the bylaws.

It may be difficult to enforce civil liabilities against us or our directors, officers and controlling persons

América Móvil is a sociedad anónima bursátil de capital variable organized under the laws of Mexico,
with its principal place of business (domicilio social) in Mexico City, and most of our directors, officers and controlling persons reside outside the United States. In addition, all or a substantial portion of our assets and their assets are
located outside of the United States. As a result, it may be difficult for investors to effect service of process within the United States on such persons or to enforce judgments against them, including in any action based on civil liabilities under
the U.S. federal securities laws. There is doubt as to the enforceability against such persons in Mexico, whether in original actions or in actions to enforce judgments of U.S. courts, of liabilities based solely on the U.S. federal securities laws.

You may not be entitled to participate in future preemptive rights offerings

Under Mexican law, if we issue new shares for cash as part of certain capital increases, we must grant our shareholders the right to
purchase a sufficient number of shares to maintain their existing ownership percentage in América Móvil. Rights to purchase shares in these circumstances are known as preemptive rights. Our shareholders do not have preemptive rights in
certain circumstances such as mergers, convertible debentures, public offers and placement of repurchased shares. We may not legally be permitted to allow holders of ADSs or holders of L Shares or A Shares in the United States to exercise
any preemptive rights in any future capital increase unless we file a registration statement with the SEC, with respect to that future issuance of shares. At the time of any future capital increase, we will evaluate the costs and potential
liabilities associated with filing a registration statement with the SEC and any other factors that we consider important to determine whether we will file such a registration statement.

We cannot assure you that we will file a registration statement with the SEC to allow holders of ADSs or U.S. holders of L Shares or
A Shares to participate in a preemptive rights offering. As a result, the equity interest of such holders in América Móvil may be diluted proportionately. In addition, under current Mexican law, it is not practicable for the
depositary to sell preemptive rights and distribute the proceeds from such sales to ADS holders.

Risks Relating to Developments in Mexico and Other Countries

Latin American and Caribbean economic, political and social conditions may adversely affect our business

Our financial performance may be significantly affected by general economic, political and social conditions in the markets where we
operate, particularly Mexico, Brazil, Colombia and Central America. Many countries in Latin America and the Caribbean, including Mexico, Brazil and Argentina have suffered significant economic, political and social crises in the past, and these
events may occur again in the future. Many of these countries, including Honduras, Uruguay and Chile, recently held elections and others including Brazil and Colombia will hold presidential elections in 2010. We cannot predict whether changes in
administrations will result in changes in governmental policy and whether such changes will affect our business. Instability in the region has been caused by many different factors, including:



| |  |  | significant governmental influence over local economies;
| | - |  | --------------------------------------------------------



| |  |  | substantial fluctuations in economic growth;
| | - |  | --------------------------------------------



| |  |  | high levels of inflation;
| | - |  | -------------------------



| |  |  | changes in currency values;
| | - |  | ---------------------------



| |  |  | exchange controls or restrictions on expatriation of earnings;
| | - |  | --------------------------------------------------------------



| |  |  | high domestic interest rates;
| | - |  | -----------------------------



| |  |  | wage and price controls;
| | - |  | ------------------------



| |  |  | changes in governmental economic or tax policies;
| | - |  | -------------------------------------------------



| |  |  | imposition of trade barriers;
| | - |  | -----------------------------



| |  |  | unexpected changes in regulation; and
| | - |  | -------------------------------------



| |  |  | overall political, social and economic instability.
| | - |  | ---------------------------------------------------

Adverse economic, political and social conditions in Latin America may inhibit demand for wireless services and create uncertainty
regarding our operating environment, which could have a material adverse effect on our company.

Our business may be
especially affected by conditions in Mexico and Brazil, our two principal markets. Mexico has experienced a prolonged period of slow growth since 2001, primarily as a result of the downturn in the U.S. economy. According to preliminary data, during
2009, Mexicos gross domestic product, or GDP, decreased by 6.54% in real terms. In 2008, GDP decreased by 1.5%. Mexico has also experienced high levels of inflation and high domestic interest rates in the past. The annual rate of
inflation, as measured by changes in the National Consumer Price Index as published by the Banco de México, was 3.57% for 2009.

Brazil has also experienced slow economic growth over the past several years. Brazils GDP decreased by an estimated 0.1% in real
terms in 2009, compared to a growth rate of 4.8% in 2008. Brazil has in the past experienced extremely high rates of inflation, with annual rates of inflation during the last years reaching as high as 2,489% in 1993 and 929% in 1994, as measured by
the Brazilian National Consumer Price Index. More recently, Brazils rates of inflation were 4.5% in 2007, 5.9% in 2008 and 4.3% in 2009. Inflation, governmental measures to combat inflation and public speculation about possible future actions
have in the past had significant negative effects on the Brazilian economy.

Our business may be affected by political
developments in Latin America and the Caribbean. We cannot predict whether these recent events will affect our business or our ability to renew our licenses and concessions, to maintain or increase our market share or profitability or will have an
impact on future strategic acquisition efforts.

Depreciation or fluctuation of the currencies in which we conduct operations relative
to the U.S. dollar could adversely affect our financial condition and results of operations

We are affected by
fluctuations in the value of the currencies in which we conduct operations compared to the U.S. dollar, in which a substantial portion of our indebtedness is denominated. Changes in the value of the various currencies in which we conduct operations
against the Mexican peso, which we use as our reporting currency in our financial statements, and against the U.S. dollar may result in exchange losses or gains on our net U.S. dollar-denominated indebtedness and accounts payable. In 2007 and 2008,
changes in currency exchange rates led us to report foreign exchange gains of Ps. 2,463 million and foreign exchange losses of Ps. 13,686 million, respectively. In 2009, we reported foreign exchange gains of Ps. 4,557 million. In addition,
currency fluctuations between the Mexican peso and the currencies of our non-Mexican subsidiaries affect our results as reported in Mexican pesos. Currency fluctuations are expected to continue to affect our financial income and expense.

Major devaluation or depreciation of any such currencies may also result in disruption of the international foreign exchange markets and
may limit our ability to transfer or to convert such currencies into U.S. dollars and other currencies for the purpose of making timely payments of interest and principal on our indebtedness. The Mexican government does not currently restrict, and
for many years has not restricted, the right or ability of Mexican or foreign persons or entities to convert pesos into U.S. dollars or to transfer other currencies out of Mexico. The government could, however, institute restrictive exchange rate
policies in the future. Also, the Brazilian government may impose temporary restrictions on the conversion of Brazilian reais into foreign currencies and on the remittance to foreign investors of proceeds from investments in Brazil. Brazilian law
permits the government to impose these restrictions whenever there is a serious imbalance in Brazils balance of payments or a reason to foresee a serious imbalance.

Oceanic Digital Jamaica Limited, or Oceanic, provides wireless and value added
services throughout Jamaica, with 0.4 million wireless subscribers as of December 31, 2009.

América
Móvil, S.A.B. de C.V. is a sociedad anónima bursátil de capital variable organized under the laws of Mexico with its principal executive offices at Lago Alberto 366, Edificio Telcel I, Colonia Anáhuac,
Delegación Miguel Hidalgo, 11320, México D.F., México. Our telephone number at this location is (5255) 2581-4449.

Our Markets, Networks and Technology

We operate pursuant to concessions, licenses or authorizations to provide wireless telecommunications services in each of the countries in
which we operate. We seek to provide a full range of wireless telecommunications services in each of our markets. Our networks are consistently optimized to try to ensure maximum coverage and high quality service. In 2009, we invested
Ps. 41,018 million in capital expenditures on our property, plant and equipment. We also seek to expand market share by exploring strategic acquisition opportunities in Latin America and the Caribbean.

We use a number of mobile technologies in the markets in which we operate. All of our markets (excluding Tracfone) have global system for
mobile communication (GSM) networks for voice and digital transmissions. Through these networks, we provide many of the voice and data services supported by GSM technology, such as short message service (SMS), circuit switch data (CSD), high speed
circuit switch data (HSCSD), packet switch data through general packet radio services (GPRS) and enhanced data rates for GSM evolution (EDGE).

During 2007, we began deploying networks based on universal mobile telecommunications systems (UMTS) in certain of our principal markets,
including Mexico, Brazil and Colombia. UMTS is a system based on the third generation (3G) of mobile phone standards and technology that allows the transmission of large volumes of data at high speeds. 3G technologies enable network operators
to offer users a wider range of more advanced services while achieving greater network capacity through improved spectral efficiency. Services include wide-area wireless phone telephony, video calls and broadband data, all in a mobile environment.
We are deploying these networks using the high-speed downlink packet access protocol (HSDPA), which is a mobile telephony communications protocol that allows networks based on UMTS to have higher data transfer speeds and capacity. Our HSDPA
deployment supports down-link speeds of 3.6 megabits per second. Our 3G networks use the same technology that is generally used throughout Europe to provide 3G services. We elected to deploy the UMTS/HSDPA networks principally because:



| |  |  | New market opportunities.    It allows us to enter new markets and provide new services, such as the wireless broadband
market, which we believe has significant growth potential throughout Latin America and the Caribbean.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Handset compatibility.    UMTS handsets are compatible with our GSM networks, so a customer can use one handset to connect
to our UMTS and GSM networks. This allows us to focus the deployment of our new networks in areas of high demand for 3G services, principally large urban areas.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Spectral compatibility.    With our new networks, we can generally offer 3G services using our existing licenses in the 850
megahertz spectrum, which is being increasingly underutilized by our remaining TDMA customers. In addition to being efficient from a cost perspective, deployment in the 850 megahertz spectrum is more efficient and provides better coverage than
deployment in the 1900 megahertz spectrum.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Increased voice capacity.    Our new networks give us approximately 5.7 times more capacity to provide voice services than
our existing GSM network using our current spectrum (considering a 5 megahertz fully-used spectrum).
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  |  | Cost effective deployment.    Unlike some of the 3G networks being deployed in the United States, UMTS networks use some of
the same basic network plant and equipment as GSM networks. This has permitted us to achieve a quicker and more cost effective deployment of 3G services, than would have been possible using other technologies.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We are the first operator to deploy these new technologies in most of our markets. We launched 3G services based on these new
technologies in Brazil during the second half of 2007 and in Mexico and Colombia during the first quarter of 2008. As of the date of this annual report, we are offering 3G services in 17 countries in Latin America and the Caribbean.

Our principal markets of operations are Mexico and Brazil, the two largest economies in Latin America. We are the largest provider of
wireless communication services in Mexico and one of the three largest in Brazil, based on the number of subscribers at December 31, 2009. In contrast to U.S. practices, both of these markets operate under a form of calling party
pays billing system, under which subscribers only pay for outgoing calls. During 2009, our Mexican operations represented 36.1% of our operating revenues and our Brazilian operations represented 20.6% of our operating revenues.

In many of our markets, the regulatory environment has become increasingly more open and flexible over the past decade. These changes
have increased competition as markets have become more open to new entrants. In Mexico, these changes have exposed us to competition from domestic competitors and from international operators. In other markets, these changes have allowed us an
opportunity to enter as a competitor and capture market share from local providers. However, we operate in many markets that have had and may continue to have volatile economic and political environments, and significant political changes may lead
to changes in regulatory environments that can adversely affect our interests and prospects.

Our Strategy

We intend to capitalize on our position as the leader in wireless telecommunications in Latin America to continue to expand our subscriber
base, both by development of our existing businesses and selected strategic acquisitions in the region. We seek to become a leader in each of our markets by providing better coverage and services and benefiting from economies of scale. We closely
monitor our costs and expenses, and we will continue to explore alternatives to further improve our operating margins.

Operating
Information

We count our wireless subscribers by the number of lines activated. We continue to count post-paid subscribers
for the length of their contracts. We disconnect, or churn, our postpaid subscribers at the moment they voluntarily discontinue their service or following a prescribed period of time after they become delinquent. We disconnect our
prepaid subscribers after a period of four months after they discontinue to use our service, so long as they have not activated a calling card or have received traffic. We calculate our subscriber market share by dividing our own subscriber figures
into the total market subscriber figures periodically reported by the regulatory authorities in the markets in which we operate. We understand that these regulatory authorities compile total market subscriber figures based on subscriber figures
provided to them by market participants, and we do not independently verify these figures.

Throughout this annual report, we
make reference to certain operating data, such as average revenues per subscriber (also referred to as ARPUs), average minutes of use per subscriber (also referred to as average MOUs per subscriber) and churn rate, that are
not included in our financial statements. We calculate ARPUs for a given period by dividing service revenues for such period by the average number of subscribers for such period. The figure includes both prepaid and postpaid customers. We calculate
churn rate as the total number of customer deactivations for a period divided by total subscribers at the beginning of such period.

##### Table of Contents

We provide this operating data because it is regularly reviewed by management and because
management believes it is useful in evaluating our performance from period to period. We believe that presenting information about ARPUs and MOUs is useful in assessing the usage and acceptance of our products and services, and that presenting churn
rate is useful in assessing our ability to retain subscribers. This additional operating information may not be uniformly defined by our competitors. Accordingly, this additional operating information may not be comparable with similarly titled
measures and disclosures by other companies.

History

We were established in September 2000 in a spin-off from Telmex, a leading provider of local and long-distance telephone services in
Mexico. The spin-off was implemented using a procedure under the Mexican General Corporations Law (Ley General de Sociedades Mercantiles) called escisión. The shares of our company were delivered to Telmex shareholders on
February 7, 2001.

Our wireless business in Mexico is conducted through our wholly-owned subsidiary Telcel, which traces
its history to the establishment in 1956 of Publicidad Turística, S.A., an affiliate of Telmex that published telephone directories. In 1981, the SCT granted Publicidad Turística, S.A. a concession for the installation and operation of
a wireless telephone system in Mexico City. In 1984, Publicidad Turística, S.A. changed its corporate name to Radiomóvil Dipsa, S.A. de C.V., and in 1989, the company began operating under the trademark Telcel.

Between 1988 and 1990, Telcel expanded its cellular network on the 850 megahertz (Band B) frequency spectrum to cover the Mexico City
metropolitan area and the cities of Cuernavaca, Guadalajara, Monterrey, Tijuana and Toluca, and in 1990, Telcel began offering cellular services in all nine geographic regions of Mexico. Telcel launched a PCS system in Mexico City in 1999 and
currently offers the service in all nine geographic regions of Mexico. In October 2002, Telcel launched its GSM network. Since December 2002, Telcel has been authorized to provide long-distance services.

In 1999, we began acquiring our international subsidiaries and investing in our Brazilian operations and our other international
affiliates. We made significant acquisitions in Latin America and the Caribbean during the past 11 years, and our non-Mexican operations have generally experienced higher subscriber growth rates in recent periods than our Mexican operations. As a
result, as of December 31, 2009, approximately 70.6% of our wireless subscribers were located outside Mexico.

In
December 2006, our shareholders approved the merger of Amtel, our then controlling shareholder, and its subsidiary, Corporativo, with us. As a result of the merger, we assumed Amtels net indebtedness, which we refinanced in January 2007. The
merger also increased the amount we may use under applicable Mexican tax rules (cuenta de utilidad fiscal neta, or CUFIN) to repurchase shares or pay dividends without incurring additional taxes.

See Mexican Operations, Non-Mexican Operations and Other Investments under this
Item 4.

On May 11, 2010, we commenced two separate but concurrent offers to acquire outstanding shares of Telmex
Internacional and CGT. Unless extended, the offers will expire on June 10, 2010. Telmex Internacional provides a wide range of telecommunications services in Brazil, Colombia and other countries in Latin America. CGT is a holding company with
controlling interests in Telmex Internacional and Telmex. Upon completion of the exchange offers, we will acquire controlling interests in CGT, Telmex Internacional (directly and indirectly thought CGT) and Telmex (indirectly through CGT). The
principal purpose of the offers is to pursue synergies between our business and that of Telmex Internacional.

The completion
of the two exchange offers is subject to conditions. It is possible that if not all such conditions are obtained or met we will not complete the exchange offers. Accordingly, there can be no assurance as to whether or when the exchange offers will
be completed.

Our Mexican business is subject to comprehensive regulation and oversight by the SCT, Cofetel, Cofeco and Profeco. The SCT is part of the
executive branch of the Mexican federal government, and Cofetel is an independent agency of the SCT. Cofeco and Profeco are independent agencies of the Ministry of Economy (Secretaría de Economía). Regulation and oversight are
governed by the General Communications Law (Ley de Vías Generales de Comunicación,or the General Communications Law), the Telecommunications Law, the telecommunications regulations adopted under both the General
Communications Law and the Telecommunications Law, the Federal Antitrust Law (Ley Federal de Competencia Económicaor Federal Antitrust Law), the Federal Customer Protection Law (Ley Federal de Protección al
Consumidor) and the concessions and license agreements granted by the SCT. See Regulation.

Unlike the
United States, Mexico uses the calling party pays system for cellular calls, under which subscribers only pay for outgoing calls, unless subscribers are outside their local area. See RegulationCalling Party Pays.

Services and Products

We offer services and products in Mexico directly through Telcel or through Telcels subsidiaries and affiliates in Mexico.

Voice services

We offer wireless voice and data services under a variety of rate plans to meet the needs of different user segments. The rate plans are
either postpaid, where the customer is billed monthly for the previous month, or prepaid, where the customer pays in advance for a specified volume of use over a specified period.

Telcels postpaid plans include the following charges:



| |  |  | monthly charges, which usually include a number of minutes of use and in some cases other services such as short text messages and/or internet services
with certain or unlimited capacity, all of which are included in the monthly service charge;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | usage charges, for usage in excess of the services specified in the monthly charge; and
| | - |  | ---------------------------------------------------------------------------------------



| |  |  | additional charges, including charges for services not included in the monthly charge, which include voicemail, general information and content.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------

Certain plans include the cost of national roaming and long-distance in the price per minute so that all
calls within Mexico cost the same amount per minute. Some postpaid plans are designed for high and moderate usage subscribers, who are typically willing to pay higher monthly fees in exchange for larger blocks of minutes that are included in the
monthly service charge, services such as voicemail, call forwarding, call waiting, caller ID and three-way calling, and lower per minute airtime charges under a single contract. To satisfy the more limited needs of low-usage postpaid subscribers,
Telcel also offers plans which provide a moderately priced, fixed monthly charge coupled with a high per minute airtime charge and relatively few included minutes. As part of postpaid plans, Telcel typically offers additional digital services such
as voicemail, call forwarding, call waiting, caller ID and three-way calling, which are all included in the monthly fee. In addition, Telcel offers its postpaid customers the flexibility to manage their additional usage costs by contracting
additional minutes of use under the prepaid system. Telcel also offers certain packages that may be added to the aforesaid plans, which could include greater SMS capacity (300, 1500 and 2500 SMS), videoconference services (65, 120, 175 or 300
minutes), internet data transfer services (2, 10, 20, 50, 150, 500 or 100 Mbs). Users may incorporate e-mail, push e-mail, file transfer, social networks and browsing services. Additionally, Telcel offers customized services to its corporate
clients. Postpaid customers may terminate plans at any time, except customers that receive a handset as part of subscribing to a plan, which must remain with the plan for at least between one year and up to two years, depending on the cost of the
handset.

Rates for postpaid plans have not increased since April 1999 and are expected to remain stable as long as the
Mexican economic environment remains stable. In recent periods, we have offered postpaid plans that include effective price-per-minute reductions. In addition, Telcel offers discounts and promotions that reduce the effective rates paid by its
customers for calls to fixed lines or Telcel and other wireless customers.

We also offer prepaid plans, known as
Amigo Kit, which includes activation or monthly charges. Prepaid customers purchase a prepaid credit for a specific amount of airtime that may be used for all services offered by Telcel, except international roaming, which is
available for prepaid customers in limited countries.

Prepaid customers typically generate lower levels of cellular usage and
are often unwilling to make a fixed financial commitment or do not have the credit profile to purchase postpaid plans. Prepaid services serve the needs of distinct consumer segments such as the youth market, families, customers with variable income
who otherwise would not be able to obtain service due to their credit profile, and customers who prefer to pay in cash. Prepaid customers also include parents who wish to control costs for their children.

##### Table of Contents

Basic rates for prepaid plans have remained unchanged since 2002. However, we offer
promotions including: (i) increase in the credit amount depending on the credit purchased; (ii) loyalty programs resulting in decreasing the per minute cost of local voice services (on-net); and (iii) free calls of up to 5 minutes and
free SMS for a determined number of preselected local on-net telephone numbers. Beginning in 2006, we offer a preferential rate to customers who have remained active for a period of at least one year with respect to certain outgoing calls. Our
prepaid subscribers may choose to be billed per minute (rounding each call to the next full minute), per second (paying a fixed rate for the first minute and another fixed rate for additional seconds), and beginning on April 2007, per call
(consisting of a fixed rate for any call lasting up to 10 minutes). Prepaid subscribers may also choose to combine per minute and per call billing (calls lasting up to two minutes are billed on a per minute basis, while calls lasting longer than two
minutes are billed on a per call basis for each additional 15 minute block).

Likewise, Telcel offers prepaid services
relating to Internet data transfers which are available in a daily, weekly and monthly basis.

National long distance rates
for prepaid plans remained at Ps. 2.25 per minute in 2009.

We believe the prepaid market represents a large and growing
under-penetrated market in Mexico. Compared to the average postpaid plan, prepaid plans involve higher average per minute airtime charges, lower customer acquisition costs and billing expenses, and low credit or payment risk. However, prepaid
customers on average have substantially lower use than postpaid customers and do not pay monthly fees and, as a result, generate substantially lower average monthly revenues per customer.

Data services

Short Message Services (SMS)

In January 2002, we began to offer two-way SMS to our customers as part of its value-added services. Since the launch of two-way SMS,
Telcel has experienced significant growth in traffic. Through arrangements with other mobile operators, Telcel began to offer to its customers the ability to send and receive short messages to and from users of networks of other carriers throughout
Mexico in the fourth quarter of 2003. Since December 2004, postpaid and prepaid customers may send and receive short messages to and from users of networks in the United States and other countries. In 2007, Telcel began to offer to its customers the
ability to send and receive short messages to and from users of Nextel México, the largest trunking carrier in Mexico.

Multimedia Messaging Service (MMS)

As an enhanced version of SMS, MMS allows customers the capability to send, in a single message, multiple color images, sounds and text to
another mobile phone or e-mail account. Telcel began to offer MMS through GSM technology to postpaid and prepaid customers in March 2003. Beginning in 2007, our customers can also send and receive multimedia messages to and from users of networks of
other Mexican carriers.

Premium SMS, Premium MMS

In April 2002, we became the first Mexican operator to offer premium information services through our SMS capabilities, including weather
reports, financial quotes and entertainment news. Other content services include personalized ring tones, text and video games, wallpapers, screensavers, themes, video clips and interactive forums.

Starting in 2003, Telcel began proving services SMS platform services to third parties, including security alarm services and notices
sent by banks to their account holders.

##### Table of Contents

Starting in June 2006, we were the first Mexican operator to offer to our postpaid customers
premium information services through our MMS capabilities, including news and weather reports, horoscopes and soccer score alerts and match results.

Content Community

To further enhance its content offerings with well-known brands, Telcel has built a Content Community through agreements and
special alliances with nationally and internationally renowned entertainment companies. These agreements and special alliances allow Telcel to offer premium content services through the Ideas Telcel and the Ideas Music Store portals,
and music download services through the Ideas Music Store portal. Although some links are shared between both portals, they are independent.

Data transmission

We offer the following technologies: High Speed Circuit Switch Data (HSCSD), packet switch data through General Packet Radio Services
(GPRS), enhanced data rates for GSM evolution (EDGE), Universal Mobile Telecommunications Systems (UMTS) and High Speed Downlink Packet Access (HSDPA).

GPRS is a non-voice value added service that allows information to be sent and received across a mobile telephone network. GPRS radio
resources are used only when users are actually sending or receiving data. Rather than dedicating a radio channel to a mobile data user for a fixed period of time, the available radio resource can be concurrently shared between several users. This
efficient use of scarce radio resources means that large numbers of GPRS users can share the same bandwidth and be served from a single cell. The number of users supported depends on the application being used and how much data is being transferred.
Because of the spectrum efficiency of GPRS, there is less need to build in idle capacity that is only used during peak hours. GPRS therefore lets Telcel maximize the use of its network resources.

EDGE is a standardized set of improvements to the GSM radio interface. EDGE and GPRS traffic can function on any GPRS network, provided
the carrier implements certain upgrades, which include certain modifications, installations and upgrades to base stations. The implementation of EDGE effectively triples the rate of gross data transmission offered by GPRS.

Because GPRS and EDGE transmit information through data channels rather than voice channels, they facilitate faster connections than
previous technologies, such as CSD and HSCSD. GPRS and EDGE services are able to accommodate corporate applications such as transmission of still and moving images, document sharing and other file transfer services, e-mail, WAP and WEB browsing,
alarms, localization and other telemetric services.

HSDPA is a wireless technology for the third generation UMTS network,
which is a wireless telephone communications protocol that allows networks based on UMTS to have higher data transfer speed and capacity. Our HSDPA deployment supports down-link speeds of 3.6.Mbs per seconds.

HSDPA not only allows Telcel to provide data transfer services offered by GSM based technologies (HSCSD, GPRS and EDGE), but also permits
the provision of services that require a greater transfer rate, such as streaming media, instant document transfer (favoring mobile use of social networks), and increased security applications, particularly for banking and commercial services.

Ideas Telcel

Through the Ideas Telcel portal, Telcel offers its customers mobile entertainment services, including SMS, MMS, e-mail, news and
personalized downloads, such as ring tones, screensavers, themes, games, applications,

chat services, images, and others. The Ideas Telcel portal is constantly being improved taking advantage of the evolution, of the Wireless Application Protocol, or WAP, which
is a global standard designed to make Internet services available to mobile telephone users. Basing our Ideas Telcel portal in WAP allows both GSM and UMTS (including those with low-cost handsets) users to use it.

Internet browsing

At present, Telcel offers WAP and WEB browsing for both GSM and UMTS networks. WAP allows a micro browser in a mobile phone to
link into a gateway service in Telcels network, the Ideal Telcel portal, enabling users to scroll through different pages of information of third parties on the Internet. Telcels WAP gateway enables its prepaid and postpaid users
to access e-mail, banking, and a variety of reservation and other types of electronic commerce services.

Likewise, Telcel
offers Internet access through HTTP (WEB protocol), which may be used by smart phones, netbooks, routers, as well as any computer using broad band cards (PC cards or USB cards) or through connection via handsets.

E-mail

E-mails, access and hosting services are available in both GSM and UMTS networks. Users may access e-mail services using WAP, as well as
WEB, allowing them to access and send e-mails not only from their handsets, but from any Internet access equipment that uses a Telcel network. Internet e-mail users may also receive SMS notification whenever they receive an incoming e-mail.

Push E-mail

Push e-mail permits constant synchronization between Telcels network and the corresponding e-mail server, thus allowing users real
time e-mail access. Additionally, tasks, calendar and contact information are also synchronized. Push e-mail services are available for BlackBerry OS, Windows Mobile, Symbian, Android, Web OS, and may be used by all smart phones offered by Telcel.

Push-to-Talk Services

In 2004, we began to offer push-to-talk services (two-way half duplex voice service) over our GSM network. Postpaid customers may use
push-to-talk over cellular, or POC, to communicate with other Telcel customers that subscribe to this service across Mexico at no cost in addition to the fixed monthly charge. POC is geared mainly towards potential customers
in the business environments.

Oficina Móvil Telcel

Oficina Móvil is a services suite designed to provide companies productivity enhancing applications. Among the services offered by
Oficina Móvil Telcel, there are push e-mail, logistic applications via bar codes, vehicle locator services, virtual voice private networks and SMS.

M-Banking

Telcel offers services that allow customers to perform certain banking activities from their mobile phones using applications developed
specially for SIM cards and profiting from the WAP protocol. These applications allow users not only to access their bank account balances, but also to carry out banking transactions.

Ideas TVIdeas Radio

In May 2006, Telcel launched TV content services which allow certain costumers to access news, cartoon, documentary and sports channels
through their handsets. Telcel provides these services through an agreement with a content distributor. Telcels TV content services, are available for EDGE users with compatible handsets, and since 2007 are also available for our UMTS users.
In 2007, Telcel launched radio contents.

Videoconference

Telcel offers simultaneous audio and video communication in real time for UMTS users.

Products

Telcel offers a variety of products as complements to its wireless service, including handsets and accessories such as chargers, headsets,
belt clips and batteries. As a result of launch and deployment of our 3G network, Telcel started to offer broadband cards and netbooks. As part of its prepaid service offering, Telcel provides new customers with an Amigo Kit,
which includes airtime, a handset, a charger and other accessories at a discounted price. For prepaid customers that own GSM and 3G handsets, Telcel also offers an Amigo Chip, which includes airtime and the chip for the handset.
New postpaid customers also receive a terminal (handset, smartphone, netbook, pccard/usb modem) a charger and other accessories complimentary or at a discounted price, if they enter into a long-term contract with Telcel.

Most of the handsets that Telcel currently offers are GSM tri-band, which can switch between the 850, 900 and 1900 megahertz radio
spectrums. In addition, Telcel offers four-band handsets, which can also operate in the 900 megahertz radio spectrum and/or the 1800 megahertz radio spectrum. Telcel no longer offers analog and TDMA handsets. Beginning in 2007, Telcel offers 3G
handsets, which operate on our 3G network and GSM network, depending on the customers location.

Interconnection

Telcel earns interconnection revenues from calls to any of its subscribers that originate with another service provider. Telcel charges
the service provider from whose network the call originates an interconnection charge for the time Telcels network is used in connection with the call. Telcel must pay interconnection fees in respect of calls made by its subscribers to
customers of other service providers (mobile and fixed). See RegulationInterconnection under this Item 4.

There has been extensive controversy, and legal and administrative proceedings, concerning the terms of interconnection in Mexico. See
RegulationInterconnection under this Item 4.

Roaming

Telcel offers international roaming services to its subscribers through the networks of cellular service providers with which Telcel has
entered into international roaming agreements around the world. Telcel also provides GSM and 3G roaming services in Mexico to customers of Telcels international roaming partners. Subscribers are able to roam out of Mexico by paying
international roaming fees. Telcel has entered into approximately 435 agreements covering GSM and 3G networks around the world. As of the date of this annual report, Telcel had commercially launched roaming GSM services covering 169 countries and
GPRS services covering 131 countries for postpaid subscribers. Telcels customers can roam in 3G networks covering 56 countries. Telcels 3G network also provides inbound roaming to customers of its international roaming partners.

Telcel and its international roaming partners are channeled through Cibernet Plc, which functions as a central international clearing house that collects and make the settlement between the participating providers.

Marketing

We develop
customer and brand awareness through our marketing and promotion efforts and high-quality customer care. We build upon the strength of our well-recognized brand name to increase consumer awareness and customer loyalty, employing continuous
advertising efforts through print, radio, television, sponsorship of sports events and other outdoor advertising campaigns. In addition, Telcel employs concentrated advertising efforts to promote specific products and services such as the
Amigo Kit and related products, certain GSM and UMTS postpaid plans and certain value-added services. In October 2003, Telcel launched Círculo Azul, a loyalty rewards program that offers postpaid
customers points that can be redeemed for handsets and other goods or services provided by third parties.

In 2009, our
marketing efforts were mainly focused on communicating that we have one of the best 3G networks in the world and showing the advantages such network has through value-added services.

Telcel targets groups of customers who share common characteristics or have common needs. Telcel then assembles a packet of services that
meets the particular needs of that targeted group through one of its various pricing plans.

Sales and Distribution

Telcel markets its wireless services primarily through exclusive distributors located throughout Mexico. In the year ended
December 31, 2009, approximately 78% of Telcels sales of handsets were generated by cellular distributors (including retail chains), with approximately 19% from sales in company-owned stores, and approximately 3% from direct sales to
corporate accounts.

As of December 31, 2009, Telcel had relationships with a network of over 1,423 exclusive
distributors, who sell Telcels services and products through approximately 41,187 points of sale and receive commissions. Telcel operates permanent training and evaluation programs for distributors to help maintain the level of service
quality.

Telcels company-owned retail stores offer one-stop shopping for a variety of cellular services and products.
Walk-in customers can subscribe for postpaid plans, purchase prepaid cards and purchase handsets and accessories. Company-owned stores also serve as points of customer service, technical support and payment centers. As of December 31, 2009,
Telcel owned and operated 259 customer sales and service centers throughout the nine regions of Mexico and will continue to open new service centers as necessary in order to offer its products directly to subscribers in more effective ways.

Telcel also distributes prepaid cards and handsets, the latter as part of the Amigo Kit consisting of
handsets and free airtime ranging from 25 to 250 minutes, through distributors that include Telmex, Sears, Sanborns and its network of retail outlets. Telmex purchases the Telcel prepaid cards and handsets on the same or similar commercial terms
offered to other cellular distributors. We estimate that, as of December 31, 2009, prepaid cards are available through approximately 160,000 points of sale in Mexico.

We sell prepaid airtime principally through the sale of cards. We also offer customers the option of buying airtime through other means.

To service the needs of its large corporate and other high-usage customers, Telcel has a
dedicated corporate sales group.

Billing and Collection

We bill our postpaid customers through monthly invoices, which detail itemized charges such as usage, services such as voicemail, call
forwarding, call waiting, caller ID and three-way calling, and long-distance, roaming charges, and value added services such as SMS, data and web usage, in addition to applicable taxes. Customers may pay their bills through pre-authorized debit or
credit charges, in person at banks (including through banks Internet websites), at Telcel retail stores and other designated retail stores, and through Telcels Internet website.

If a postpaid customers payment is overdue, service may be suspended until full payment for all outstanding charges is received. If
the subscribers payment is more than 60 days past due, service may be discontinued. Accounts that are more than 90 days past due are considered doubtful accounts.

A prepaid customer who purchases airtime credit has between 7 to 60 days, depending on the amount purchased, to use the airtime. It is
possible to purchase airtime credit in any of the following amounts: Ps.30, Ps.50, Ps.150, Ps.200, Ps.300 and Ps.500. Users may also use the pasatiempo service, which allows one prepaid user to transfer up to Ps.100 of airtime credit to
another prepaid user by sending a SMS. After 30 or 60 days, the customer can no longer use that airtime for outgoing calls unless the customer purchases additional airtime credit. After 180 days, unless the customer has purchased additional airtime
credit, the service is discontinued and the balance, if any, is recognized as revenue.

Customer Service

Telcel places a high priority on providing its customers with quality customer care and support. Approximately 68% of Telcels
employees are dedicated to customer service. Customers may call a toll-free telephone number or go to one of the customer sales and service centers located throughout the nine regions for inquiries regarding their service or plan options. In
addition, using Telcels website, subscribers may learn about the various offered rate plans, products and promotions, as well as subscribe for additional services and pay bills on line.

Wireless Network

Telcels wireless networks use digital technologies both in the 850 megahertz frequency spectrum and in the 1900 megahertz frequency
spectrum. In October 2002, Telcel launched a new network using global system for mobile communications (GSM) digital technology in the 1900 megahertz frequency spectrum. GSM is a digital standard used in Europe, North America and elsewhere and it is
the most widely used digital wireless technology in the world. In 2006, Telcel started deploying the GSM, GPRS and EDGE technologies in the 850 megahertz frequency spectrum. In February 2008, Telcel launched a UMTS third generation network in Mexico
in the 850 megahertz frequency spectrum. Telcel maintains a TDMA network in the 850 megahertz frequency spectrum. TDMA is a digital technology developed previously than GSM network that divides radio spectrum into assigned time slots to transmit
signals.

GSM network

Telcel has built and installed a GSM network in the 1900 megahertz frequency spectrum in all nine regions in Mexico, which began
commercial operation in October 2002. Telcel continues with the expansion of its GSM network, using the 850 megahertz spectrum since 2006. The GSM network allows Telcel to augment its digital capacity and progress in its evolution toward the third
generation of wireless technology. GSM technology supports a wide range of voice and data services, including SMS, MMS, HSCSD, GPRS and EDGE, and is

##### Table of Contents

currently the most widely used and tested wireless system in the world. GSM technology, which is used in all nine regions, is expected to yield global economies of scale in developing network
equipment and handsets, as well as seamless global roaming capabilities.

Currently, Telcels GSM network offers service
in all nine regions in Mexico. As of December 31, 2009, Telcels GSM subscriber base accounted for approximately 92% of Telcels total subscribers.

Telcel upgraded the GSM/GPRS network with EDGE technology. It has implemented EDGE technology in more than 186,984 localities, including
all the major cities in Mexico. EDGE can be deployed in existing spectrum with minimum changes in hardware. As customers upgrade their equipment to EDGE, Telcel expects that all the applications developed and deployed today will be able to operate
at significantly higher speeds and in more places.

Third generation technologies

Third generation (3G) technologies provide high-speed wireless packet data access and all Internet-related services that can be
offered through broadband with the advantage of mobility. Any successful third generation strategy must allow the wireless provider to achieve a pervasive footprint quickly and cost effectively and on a global scale through international roaming
capacities.

Telcel is deploying a UMTS third generation network in Mexico using the existing 850 megahertz spectrum and began
offering 3G services in February 2008. 3G technologies enable network operators to offer users a wider range of more advanced services while achieving greater network capacity through improved spectral efficiency. Services include wide-area wireless
phone telephony, video calls and broadband data, all in a mobile environment. Telcel is deploying its UMTS network using the high-speed downlink packet access protocol (HSDPA), which is a mobile telephony communications protocol that allows networks
based on UMTS to have higher data transfer speeds and capacity. Telcels HSDPA deployment supports down-link speeds of 3.6 megabits per second. Our 3G networks use the same technology that is generally used throughout Europe to provide 3G
services. We elected to deploy the UMTS/HSDPA networks principally because:



| |  |  | New market opportunities.    It allows us to enter new markets and provide new services, such as the wireless broadband
market, which we believe has significant growth potential throughout Latin America and the Caribbean.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Handset compatibility.    UMTS handsets are compatible with our GSM networks, so a customer can use one handset to connect
to our UMTS and GSM networks. This allows us to focus the deployment of our new networks in areas of high demand for 3G services, principally large urban areas.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Spectral compatibility.    With our new networks, we can generally offer 3G services using our existing licenses in the 850
megahertz spectrum, which is being increasingly underutilized by our remaining TDMA customers. In addition to being efficient from a cost perspective, deployment in the 850 megahertz spectrum is more efficient and provides better coverage than
deployment in the 1900 megahertz spectrum.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Increased voice capacity.    Our new networks give us approximately 5.7 times more capacity to provide voice services than
our existing GSM network using our current spectrum (considering a 5 megahertz fully-used spectrum).
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Cost effective deployment.    Unlike some of the 3G networks being deployed in the United States, UMTS networks use some of
the same basic network plant and equipment as GSM networks. This has permitted us to achieve a quicker and more cost effective deployment of 3G services, than would have been possible using other technologies.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

Telcel is the first operator to deploy UMTS/HSDPA technologies in Mexico. As of
December 31, 2009, Telcels UMTS/HSDPA network covered 101,209 localities, including all of Mexicos principal cities. Telcel plans to continue expanding its 3G coverage in Mexico throughout 2010. As of December 31, 2009,
Telcels UMTS/HSDPA subscriber base accounted for approximately 4% of Telcels total subscribers.

Telcel currently
relies on Ericsson for the supply of more than 41% (measured in terms of cost) of its switch and cell site equipment. Telcel purchases handsets and other customer equipment primarily from the major vendors in the industry, including Nokia Research
in Motion (RIM), Sony-Ericsson, Apple, Motorola, LG, and Samsung.

TDMA network

Telcel has a nationwide TDMA network. TDMA permits the use of advanced dual-band handsets that allow for roaming across analog and digital
systems and across 850 megahertz and 1900 megahertz spectrums. TDMA digital technology also allows for enhanced services and features, such as SMS, extended battery life, added call security and improved voice quality. This network is currently used
by subscribers who have not yet migrated to newer networks.

Spectrum

Telcel currently holds concessions in each of the nine regions of Mexico in both the 850 megahertz and 1900 megahertz radio spectrums and
has a functioning nationwide network. Two other companies also hold concessions for nationwide service using the 850 or 1900 megahertz spectrum.

Telcel currently holds 28.4 megahertz of capacity in the 1900 megahertz spectrum in each of Mexicos nine regions. It acquired 10
megahertz (Band D) of this capacity in 1998 and 10 megahertz (Band F) in 2005, in each case through public auctions. Telcel acquired 8.4 megahertz (Band A) as a result of the assignment of capacity from Unefon, S.A. de C.V. during 2005. This
assignment was approved by Cofeco and the SCT and no considerationin addition to the U.S.$267.7 million (Ps. 3,309 million) paid to Unefon in 2003 for the service agreementwas paid for the assignment.

Fixed wireless

Fixed wireless technology provides wireline quality voice telephony available over cellular networks. Voice channels are delivered over
the existing telephone wiring within the residence or small business premises, allowing customers to utilize their existing telephones.

Telcel provides public fixed wireless services in rural, semi-urban and urban regions in Mexico.

Property

Telcels
wireless network includes transport and computer equipment, as well as exchange and transmission equipment consisting primarily of switches (which set up and route telephone calls either to the number called or to the next switch along the path, and
which may also record information for billing and control purposes), cellular base stations (radio transmitters or receivers that maintain communications with the cellular telephones within given geographical areas or cells), microcells
(small cells covered by low-power base stations), and local links and repeaters (equipment for radio or fiberoptic transmission between network elements). Telcel owns all of its network routing and switching equipment. Telcel owns certain properties
for commercial and administrative offices, the installation of some of its equipment, and 190 customer sales and service centers, while it leases other locations. Telcel operates certain equipment on Telmex property under a co-location agreement.
See Related Party Transactions under Item 7.

Telcel currently relies on Ericsson for the supply of approximately 41% (measured in terms
of cost) of its switch and cell site equipment. Telcel purchases handsets and other customer equipment primarily from the major vendors in the industry, including Nokia, Research in Motion (RIM), Sony-Ericsson, Apple, Motorola, LG and Samsung.

Competition

Telcel faces competition from other mobile providers using the 850 megahertz spectrum and from providers with PCS licenses that have
developed and continue to develop wireless service on the 1900 megahertz spectrum. Telcels principal competitors in Mexico are Grupo Iusacell, S.A. de C.V. and Telefónica Móviles. We also compete with Nextel in certain segments.
According to Cofetel, Telcels share of the Mexican cellular market was approximately 74% as of December 31, 2009.

The effects of competition on Telcel depend, in part, on the business strategies of its competitors and the general economic and business
climate in Mexico, including demand growth, interest rates, inflation and exchange rates. The effects could include loss of market share and pressure to reduce rates. Telcel believes that its strategies to meet competition will continue to help
limit its loss of market share and that any loss of market share will be partly offset by increasing demand.

Regulation

The following is a summary of certain provisions of the General Communications Law, the Telecommunications Law, Federal Customer
Protection Law and the telecommunications regulations applicable to Telcel and of the various concessions held by Telcel.

General

The General Communications Law, the Telecommunications Law and the telecommunications regulations provide the general legal framework for
the regulation of telecommunications services in Mexico. The Telecommunications Law replaced certain provisions of the General Communications Law and established that only those provisions of the General Communications Law not opposed to the
Telecommunications Law would remain in effect. Other regulations implementing particular provisions of the Telecommunications Law have been adopted or are pending. The main objectives of the Telecommunications Law are to promote the efficient
development of the telecommunications industry, to encourage fair competition in the provision of quality, low-priced services and to assure satisfactory breadth of coverage of the Mexican population.

Under the Telecommunications Law, an operator of public telecommunications networks, such as Telcel, must operate under a concession
granted by the SCT. Such a concession may only be granted to a Mexican citizen or corporation and may not be transferred or assigned without the approval of the SCT. A concession to provide services which utilize electro-magnetic frequencies, such
as cellular telecommunications services, may have a term of up to twenty years and may be extended for additional terms of equal duration.

The Telecommunications Law requires public telecommunications concessionaires to establish open network architecture which permits
interconnection and interoperability. Operators of private networks that do not use electro-magnetic frequencies or provide services to the public are not required to obtain a concession, permit or registration.

Regulatory oversight

The SCT, through Cofetel, is the government agency principally responsible for regulating telecommunications services. The SCTs
approval is required for any change in Telcels bylaws. It also has broad powers to monitor Telcels compliance with the concessions, and it can require Telcel to supply it with such technical, administrative and financial information as
it may request. Telcel is required to publish its annual network expansion program and must advise the SCT of the progress of its expansion and modernization program on a quarterly basis.

##### Table of Contents

Cofetel is an independent agency within the SCT, with five commissioners appointed by the
President of Mexico, one of whom is appointed as chairman. Cofetels mandate is to regulate the Mexican telecommunications sector. Many of the powers and obligations of SCT under the Telecommunications Law and the telecommunications regulations
have been delegated to Cofetel.

The Telecommunications Law gives certain rights to the Mexican government in its relations
with concessionaires, including the right to take over the management of an operators networks, facilities and personnel in cases of imminent danger to national security, internal peace or the national economy, natural disasters and public
unrest. The Telecommunications Law also provides that at the expiration of Telcels concessions, the Mexican government has a right of first refusal to acquire Telcels assets used directly in the exploitation of frequency bands. See
Termination of the Concessions under this Item 4.

In addition, we are subject to regulation from
Profeco under the Federal Consumer Protection Law. This law regulates publicity, the quality of services and information required to be provided to consumers and provides a mechanism to address consumer complaints. Profeco has the authority to
impose fines, which can be significant.

Antitrust Investigations

The Telecommunications Law authorizes SCT to impose specific requirements as to rates, quality of service and information on any wireless
operator that is determined by Cofeco to have substantial power in a specific market according to the Federal Antitrust Law. Pursuant to the Telecommunications Law, SCT has the power to adopt specific regulations on rates, quality of service,
disclosure of information or other special regulations.

Cofeco is conducting investigations into market power and
monopolistic practices in the telecommunications sector. Depending on the resolution of these investigations, they may result in new regulations applicable to Telcel. See Legal ProceedingsMexicoCofeco under Item 8.

Number Portability

Cofetel rules for the portability of fixed-line and mobile telephone numbers took effect in June 2008. One of the objectives of these
rules is to increase competition among operators. The portability rules allow customers to change providers without contacting their current provider, so we may lose customers without having the opportunity to influence their decision. The rules
also require that we bear the costs of changes in our network and any other investments necessary to implement portability, without being able to charge other operators. To date, the portability rules have not materially affected our subscriber
base.

Rates

The Telecommunications Law provides that concessionaires may freely determine the rates for telecommunications services, including
interconnection. Mobile rates are not subject to a price cap or any other form of price regulation. However, Telcel and other mobile carriers operating in Mexico are required to register with Cofetel their rates for mobile service prior to
implementing such rates. Cofetel is authorized to impose specific rate requirements on any operator that is determined to have substantial market power under the Federal Antitrust Law. Although COFECO has determined that Telcel has substantial
market power in the nationwide market for voice services, we cannot predict what regulatory measures might be taken in response to COFECOs determination.

In addition to the cellular and PCS concessions
detailed in the tables above, in December 2002, the SCT granted Telcel a concession to install and operate a telecommunications network to provide national and international long distance services, as well as data transmission services. The
concession was granted for an

initial term of 15 years, and it is subject to extension for an additional 15-year period. The concession
limited Telcel to provide these services only to its wireless subscribers until December 2005. In 2006, Telcel completed the build out of its long distance network which allows Telcel to carry all the national long distance traffic originated from
Telcels customers to other customers. Also, since May 2007, Telcel opened its interconnection with the local network of Telmex in Mexico City and with the long distance network of AT&T.

ConcessionsFees

There are two different types of fees that we may be required to pay in connection with our concessions.

Aprovechamientos.Some concessions require Telcel to pay semi-annual fees (aprovechamientos) equal
to a percentage of gross revenues derived from the concessioned services. The percentage ranges between 5% and 10%. These fees apply to the 850 megahertz (Band B) concessions, except for Region 9 which covers Mexico

City and the states of Mexico, Morelos and Hidalgo. For the Region 9 Band B concession, these fees were eliminated pursuant to a court decision, against an increase of Ps. 2,149.5 million in
the aggregate consideration payable for the concession (from Ps. 116.4 million to Ps. 2,265.9 million). Telcel paid Ps. 150.9 million in cash and credited Ps. 1,998.5 million of fees it had previously paid. Fees of this type do
not apply to the 1900 megahertz (Band D) concessions, which Telcel purchased for a fixed amount in 1998, and the 1900 megahertz (Band A) concessions, which Telcel acquired from Unefon.

Derechos.Owners of concessions granted or renewed on or after January 1, 2003 are required to pay
annual fees (derechos) for the use and exploitation of radio spectrum bands. The amounts payable are set forth by the Ley Federal de Derechos and vary depending on the relevant region and radio spectrum band. These annual fees apply to
all spectrum bands, including those that are already subject to the payment of fees (aprovechamientos) based on gross revenues. Currently, we are not required to pay these fees in respect of our Bands A, B and D concessions since they were
awarded prior to 2003, but we are required to pay them in respect of additional 10 megahertz of capacity in the 1900 megahertz spectrum (Band F) acquired in 2005.

Telcel challenged the validity of these annual fees, on the grounds that they violate the Mexican Constitution and certain
provisions of the Telecommunications Law. In January 2009, one chamber (sala) of the Mexican Supreme Court denied our request for an injunction, but that decision was subject to rehearing because another chamber
(sala) issued a contrary ruling in a case brought by another operator challenging the same law. In April 2009, the Mexican Supreme Court definitively denied Telcels request for an injunction. Telcel has paid the annual
fees notwithstanding its legal challenges.

ConcessionsExpansion, modernization and service quality
requirements

Telcels concessions impose a number of requirements for expansion and modernization of its network.
The concessions establish certain minimum network capacities that Telcel must achieve, to extend service coverage to a targeted percentage of population. Telcel is in compliance with these requirements.

The concessions also set forth extensive requirements for the quality and continuity of Telcels service, including, in some cases,
maximum rates of incomplete and dropped calls and connection time. In May 2003, Cofetel issued the Fundamental Technical Plan for Quality of Local Mobile Services Networks, applicable to all operators, including Telcel, which imposes additional
service quality requirements. We are in compliance with the service quality requirements of our concessions and the Technical Plan.

ConcessionsCompetition

The telecommunications regulations and the concessions contain various provisions designed to introduce competition in the provision of
communications services. In general, the SCT is authorized to grant concessions to other parties for the provision of any of the services provided by Telcel under the concessions.

ConcessionsRenewal

The eight Band B concessions covering regions other than the Mexico City area were granted for initial terms of twenty years that will
expire in 2010 or 2011. Our ability to renew the eight Band B concessions in the coming years will be subject to a number of factors beyond our control. Among other possible factors, renewal of the eight concessions will be conditioned on our
compliance with the terms and conditions of the relevant concessions during their terms, payment of a renewal fee and our acceptance of terms and conditions which may differ from those applicable under the existing concessions.

During the first quarter of 2010, the SCT recognized Telcels right to renew, for additional 15-year terms, its 8 Band B
concessions, covering all regions other than the Mexico City area and requested Telcel accept terms and conditions with the concessions and pay an upfront fee. Telcel has accepted the terms and conditions determined by SCT and paid the upfront fee.

##### Table of Contents

The Band B concession covering the Mexico City area (Region 9) was renewed effective October
2000 for a term of fifteen years that will expire in October 2015. On April 20, 2010 Telcel requested renewal of the Band B concession covering the Mexico City area (Region 9). The Band D concessions will expire in 2018, the Band A
concessions in 2019 and the Band F concessions in 2025. All of these concessions are subject to renewal for additional 20-year terms.

ConcessionsTermination

The General Communications Law, the Telecommunications Law and the concessions include various provisions under which the concessions may
be terminated before their scheduled expiration dates. Under the Telecommunications Law, the SCT may cause early termination of any of the concessions in certain cases, including:



| |  |  | failure to exercise rights under a concession during the 180 days after that concession is granted;
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | failure to expand telephone services at the rate specified in the concession;
| | - |  | -----------------------------------------------------------------------------



| |  |  | interruption of all or a material part of the services provided by Telcel;
| | - |  | --------------------------------------------------------------------------



| |  |  | acts by Telcel with the effect of impeding the operations of other concessionaires;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | refusing interconnection arrangements with other concessionaires;
| | - |  | -----------------------------------------------------------------



| |  |  | change of jurisdiction by Telcel;
| | - |  | ---------------------------------



| |  |  | transfer, assignment of, or grant of liens to, Telcels concessions or any asset used to provide service without SCTs approval;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------



| |  |  | failure to pay certain government fees;
| | - |  | ---------------------------------------



| |  |  | violation of the prohibition against ownership of shares of Telcel by foreign states;
| | - |  | -------------------------------------------------------------------------------------



| |  |  | any material modification of the nature of Telcels services without prior SCTs approval; and
| | - |  | ----------------------------------------------------------------------------------------------



| |  |  | breach of certain other obligations under the General Communications Law.
| | - |  | -------------------------------------------------------------------------

In addition, the concessions provide for early termination by the SCT following administrative proceedings in the event of:



| |  |  | a material and continuing violation of any of the conditions set forth in the concessions;
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | material failure to meet any of the service expansion requirements under the concessions;
| | - |  | -----------------------------------------------------------------------------------------



| |  |  | material failure to meet any of the requirements under the concession for improvement in the quality of service;
| | - |  | ----------------------------------------------------------------------------------------------------------------



| |  |  | engagement in any telecommunications business not authorized under the concession and requiring prior approval of the SCT;
| | - |  | --------------------------------------------------------------------------------------------------------------------------



| |  |  | following notice and a cure period, failure without just cause to allow other concessionaires to interconnect their networks to Telcels network;
or
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | bankruptcy of Telcel.
| | - |  | ---------------------

The General Communications Law and all but one of Telcels 850 megahertz concessions provide that in the event of early termination
of Telcels mobile concessions, all assets that are the subject of such concession would revert to the Mexican government without compensation to Telcel. In the event of early termination of any of Telcels PCS concessions, the Mexican
government would have the option to purchase the equipment, installations and other assets used directly for the exploitation of the frequencies which are the subject of such concession. The latter regime also applies to one of Telcels 850
megahertz concessions.

Calling Party Pays

In Mexico, calls to and from our mobile subscribers are subject to the calling party pays system, under which subscribers only
pay for outgoing calls. Subscribers have the option of retaining the mobile party pays system. The calling party pays system has applied to local calls since 1999 and to long-distance calls since November 2006. Mobile
operators do not charge airtime fees to customers receiving calls, except for roaming fees applicable when subscribers receive calls outside their local areas. Two long-distance carriers, Axtel and Avantel, have challenged the validity of the long
distance calling party pays system through judicial proceedings and are operating under a court order obtained in those proceedings that temporarily suspends the application to them of the calling party pays system.

Interconnection fees

Under the calling party pays system, when the customer of one operator (local or long-distance) places a call to a customer of another
operator, the first operator pays the second a fee, which is referred to as an interconnection fee.

Under Mexican law,
interconnection fees are negotiated between operators. For some periods, we have been unable to reach agreement on fees with some operators, and operators that are unable to agree have sought the intervention of Cofetel to establish interconnection
fees. Our interconnection agreements with each operator require us to offer that operator the best rates we offer to other similar operators, and as a result if a single operator obtains a more favorable rate through a final, non-appealable
resolution or decision from Cofetel, SCT or the courts, we may be required to offer that rate to other operators even though we have previously agreed with them on rates.

There has been extensive controversy in Mexico concerning the interconnection fees payable by fixed-line operators to mobile operators on
fixed-to-mobile calls for periods beginning with 2005. The principal stages in the controversy, as it relates to interconnection with Telcel, are summarized below.



| |  |  | December 2004 Agreement.    In December 2004, most Mexican telecommunications operators agreed on interconnection fees for
the years 2005 through 2007. The agreement provided for annual reductions of 10% and also provided that the reductions would be reflected in the tariffs charged by fixed operators to their customers. The following are the interconnection fees agreed
upon in December 2004:
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | January 1, 2005 to December 31, 2005: Ps. 1.71 per minute or fraction;
| | - |  | ----------------------------------------------------------------------



| |  |  | January 1, 2006 to December 31, 2006: Ps. 1.54 per minute or fraction; and
| | - |  | --------------------------------------------------------------------------



| |  |  | January 1, 2007 to December 31, 2007: Ps. 1.34 per minute or fraction.
| | - |  | ----------------------------------------------------------------------



| |  |  | August 2006 Cofetel Resolutions.    Axtel, independently, and Avantel and Alestra, jointly, began proceedings with Cofetel
(desacuerdos de interconexión) to establish the applicable interconnection fees for termination of public commuted traffic under the calling party pays system in local mobile service networks, between them and Telcel.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

As a result of the proceedings (desacuerdos de interconexión), on August 31, 2006,
Cofetel issued two resolutions (the Axtel Resolution and the Avantel/Alestra Resolution) establishing the local interconnection fees payable by the two carriers to Telcel for the years 2005 through 2010, as follows: from
(i) January 1 to December 31, 2005: Ps. 1.71 per interconnection minute; (ii) January 1 to September 30, 2006: Ps. 1.54 per interconnection minute; (iii) October 1, 2006 to December 31, 2007:
Ps. 1.23 per interconnection minute; (iv) January 1 to December 31, 2008: Ps. 1.12 per interconnection minute; (v) January 1 to December 31, 2009: Ps. 1.00 per interconnection minute;
(vi) January 1 to December 31, 2010: Ps. 0.90. Several of these fees were lower than the fees Telcel had agreed with other operators.

##### Table of Contents

In addition, Cofetel ruled that starting in 2007, interconnection fees would be determined
by adding the total seconds of all completed calls rounded to the next minute, rather than by rounding each call to the next minute, before calculating the sum of total network occupation. In order to mitigate the effects of this change on Telcel,
Cofetel authorized Telcel to collect a surcharge of 25% in 2007, 18% in 2008 and 10% in 2009 over the interconnection fees billed to Axtel, Avantel y Alestra. Telcel challenged the Axtel Resolution and the Avantel/Alestra Resolution.



| |  |  | August 31, 2006 Avantel/Alestra Resolution.    Telcel challenged Cofetels August 2006 Avantel and Alestra
Resolution on interconnection rates between the two carriers and Telcel. In November 2009, the court decided that Cofetel was not empowered to add elements to the controversy set forth in the proceedings (desacuerdos de interconexión)and could not issue resolutions on matters which were not originally requested (for example, interconnection fees for the years 2008 to 2010). Consequently, the August 2006 Avantel and Alestra Resolution was declared without effect, and Cofetel
was ordered to issue a new resolution establishing interconnection fees for the years 2005 to 2007. However, the courts ruling was silent in respect of the analysis and the assessment of several of the acts challenged by Telcel. Accordingly,
in December 2009 Telcel challenged the ruling before the competent courts. Cofetel also challenged the ruling. Avantel joined the two challenges through a recurso de revisión adhesiva.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | August 31, 2006 Axtel Resolution, December 2007 Judicial Decision and January 2008 Cofetel Resolution.    In September
2006, Telcel began a judicial proceeding (juicio de amparo) challenging the Axtel Resolution on interconnection rates between Axtel and Telcel. In December 2007, the district court invalidated the Axtel Resolution in its entirety and directed
Cofetel to issue a new resolution covering solely the periods from 2005 through 2007. In January 2008, as directed by the court, Cofetel issued a resolution establishing interconnection rates between Telcel and Axtel for the periods from 2005
through 2007 on the same terms as Cofetels August 2006 resolution. Telcel challenged this resolution as to the rates applicable for that period. In October 2009, the court ruled against Telcel finding that, among other things, the model used
by Cofetel to calculate interconnection fees had been appropriate. In its ruling, the court determined that the interconnection fees resulting from Cofetels model should be: (i) Ps. 0.71 for 2005; (ii) Ps. 0.74 for 2006; and
(iii) Ps. 0.78 for 2007. Telcel challenged (recurso de revisión) the ruling arguing that, even if Cofetels model was appropriate, the results obtained by the judge were erroneous because Cofetel did not use real and updated
information while implementing their methodology. Cofetel also challenged the ruling. Axtel joined the two challenges through a recurso de revisión adhesiva.

| |  |  | December 2006 Agreements.    In the fourth quarter of 2006, most industry operators other than Axtel and Avantel, agreed on
interconnection fees payable for termination services for local and long-distance (national and international) calls in mobile networks under the calling party pays system for the years 2005 through 2010. These agreements contemplated
the following continued reductions in fees: (i) 2005: Ps. 1.71 per interconnection minute; (ii) 2006: Ps. 1.54 per interconnection minute; (iii) 2007: Ps. 1.34 per interconnection minute; (iv) 2008: Ps.
1.21 per interconnection minute; (v) 2009: Ps. 1.09 per interconnection minutes; and (vi) 2010: $1.00 per interconnection minute.

| |  |  | 2008 Proceedings Involving Axtel.    In December 2007 and March 2008, Axtel initiated proceedings with Cofetel to establish
interconnection rates for the years from 2008 through 2011. In May 2008, before Cofetel issued a resolution, Axtel obtained a court order to prevent Cofetel from issuing a resolution on interconnection between Axtel and Telcel. Axtel then filed an
administrative review proceeding (recurso de revision) with the Mexican Ministry of Communications and Transportation (Secretaría de Comunicaciones y Transportes or SCT). Axtel contended that, by failing to issue a resolution on
interconnection between Axtel and Telcel for interconnection fees for 2008 through 2011, Cofetel had refused to act (negativa ficta). Through the administrative review proceeding (recurso de revision), Axtel requested that the SCT
review that refusal.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In July 2008, Telcel obtained a court order which prevented the SCT from ruling on
Axtels challenge to Cofetels supposed refusal to act on interconnection fees between Axtel and Telcel.

##### Table of Contents

However, in September 2008, SCT issued a resolution establishing the following
interconnection fees for 2008 through 2011: (i) 2008: Ps. 0.5465 per interconnection minute; (ii) 2009: Ps. 0.5060 per interconnection minute; (iii) 2010: Ps. 0.4705 per interconnection minute; and (iv) 2011: Ps.
0.4179 per interconnection minute. These fees are substantially less than the fees agreed upon with the rest of the industry operators. Telcel challenged the resolution and, in October 2008, obtained a court order suspending the effects of it
until a final ruling is issued.



| |  |  | April 2009 Cofetel ResolutionAvantel Interconnection Disagreement.    In April 2009, Cofetel issued a resolution
establishing the following interconnection fees for 2008 through 2010 applicable between Avantel (a subsidiary of Axtel) and Telcel for termination of public commuted traffic under the calling party pays system in Telcels mobile
network: (i) 2008: Ps. 1.12 per interconnection minute plus a surcharge of 18% over the total interconnection minutes billed; (ii) 2009: Ps. 1.00 per interconnection minute plus a surcharge of 10% over the total minutes billed;
and (iii) 2010: Ps. 0.90 per interconnection minute without any surcharge, based on the assumption that the valuation method consist of adding the actual duration of the calls measured in seconds and then rounding up to the next minute. In
May 2009, Telcel challenged the resolution and a final judicial decision is still pending.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We expect that
interconnection fees for fixed-to-mobile calls will continue to be the subject of litigation and administrative proceedings. We cannot predict when or how these matters will be resolved. The competitive and financial effects of any resolution could
be complex and difficult to predict. Although the matters in dispute primarily concern one operator, Axtel (and its subsidiary Avantel), if those matters are resolved adversely to us through a final, non-appealable resolution or decision from
Cofetel, SCT or the courts, the impact could be material because Telcel would be required to offer to the other operators any more favorable fees it is required to provide to Axtel and/or Avantel, as of the date of such final, non-appealable
resolution or decision. This could materially reduce Telcels interconnection revenues in future periods. Also, depending on how the disputes are resolved, there could be contractual claims among Axtel and/or Avantel, and Telcel for
reimbursement or payment, as the case may be, of amounts paid or owed between Telcel and Axtel and/or Avantel in respect of time periods from 2005 to 2010.

February 2009 Interconnection Plan

In February 2009, Cofetel published a Fundamental Technical Plan of Interconnection and Inter-operability (Plan Técnico
Fundamental de Interconexión e Interoperabilidad, or the Plan). The Plan addresses the technical, economic and legal conditions of interconnection. With respect to interconnection fees, the Plan establishes a process for
developing an economic model over a relatively brief period and then applying the economic model to determine fees, which could override the existing fee agreements among operators. The Plan also contemplates asymmetrical and discriminatory
treatment for operators with the largest number of access points, including specific technical and legal requirements and different economic, technical and legal conditions from other operators.

We cannot predict the competitive and financial effects that might result from implementation of the Plan. They could be substantially
different from the potential effects of the regulatory steps described above with respect to fixed-to-mobile interconnection. It is also difficult to anticipate the timetable for implementation of the Plan.

In March 2009, Telcel has challenged the Plan in the Mexican courts. In April 2009, Telcel obtained a court order suspending the effects
of the Plan as they relate to Telcel pending resolution of its judicial challenge. As of the date of this annual report, the challenge remains pending.

Consolidation of Local Service Areas

In March 2007, Cofetel issued a resolution to eliminate 70 local service areas and in September 2008, it issued a resolution to eliminate
an additional 125 local service areas, reducing the total number of local service



41

##### Table of Contents

areas from 397 to 202 in a process that began in November 2008 and will be completed in 2010. If implemented as issued, the resolution would have the effect of requiring mobile operators to
reassign the local area code numbers for a significant number of their subscribers. We are currently in discussions with Cofetel for a technical solution to the reassignment of local area codes as a result of the consolidation. As of the date of
this annual report, we have not reached an agreement with Cofetel regarding this matter. We do not expect the consolidation of local service areas to have a significant negative impact on our results of operations.

Mobile Telephone National User Registry

In February 2009, the Federal Telecommunications Law was amended in order to create the Mobile Telephone National User Registry
(Registro Nacional de Usuarios de Telefónia Móvil or RENAUT). In accordance with said amendment, operators must maintain a registry including the identity of all their subscribers and a ledger of all communications
made by each users line as well as provide to the relevant authorities information obtained. Among other provisions, the amendment establishes that users who purchased a mobile line after April 10, 2009 (date when the amendment became
effective), could not use it until they register their line with the RENAUT. Likewise, the amendment establishes that existing users as of the date in which the amendment became effective had a one-year term to register the mobile telephone line.
Consequently, lines that were not registered as of April 10, 2010, were to be suspended without a reactivation right by operators. Pursuant to applicable regulations issued by Cofetel, Telcel has complied with the line and communication
registry as well as the information provision processes.

Notwithstanding the foregoing and solely for purposes of protecting
its subscribers from the suspension ordered by the amendment, Telcel began a judicial proceeding (juicio de amparo) against certain provisions of the Federal Telecommunications Law. The enforceability of the relevant provisions of the
amendment has been stayed by a court order. We expect final resolution of the juicio de amparo during 2010.

Telcel
continues to fulfill all actions required in connection with the registry of its subscribers (both new and preexisting) and of their communications as well as the information provision process in compliance with the rules issued by Cofetel to comply
with the Federal Telecommunications Law.

NON-MEXICAN OPERATIONS

We have subsidiaries or businesses in the telecommunications sector in Brazil, the Southern Cone region (Argentina, Paraguay, Uruguay and
Chile), Colombia and Panama, the Andean region (Ecuador and Peru), Central America (El Salvador, Guatemala, Honduras and Nicaragua), the United States and the Caribbean (the Dominican Republic, Jamaica and Puerto Rico). Our principal subsidiaries
outside Mexico are described below. The revenues of our subsidiaries other than Telcel represented 63.9% of our consolidated revenues for 2009, as compared to 60.9% of our consolidated revenues for 2008.

In addition, we expect to have opportunities to invest in other telecommunications companies outside Mexico, especially in Latin America
and the Caribbean, because we believe that the telecommunications sector will continue to be characterized by growth, technological change and consolidation. We may take advantage of these opportunities through direct investments or other strategic
alliances.

The following table sets forth financial and operating information for certain of our non-Mexican operations for
the periods indicated. Lines in service are presented as of year-end. For some segments or periods, information may not be comparable to prior periods because it includes the results of operations of acquired companies as from the date of
consolidation in our financial statements. See Note 20 to our audited consolidated financial statements.

Brazil (Claro Participações)

General

Claro Participações S.A , or Claro Participações, through its subsidiaries is one of the three
largest providers of wireless telecommunication services in Brazil, with an estimated nationwide market share in Brazil at December 31, 2009, of approximately 25.5%. Brazil is the largest market in Latin America in terms of wireless customers.

Claro Participações provides services in Brazil under a unified brand name and it offers a variety of rate
plans to its postpaid customers and offers prepaid services in all of its markets. At December 31, 2009, Claro Participações served approximately 44.4 million subscribers compared to 38.7 million subscribers at
December 31, 2008 and our licensed area covered approximately 192 million licensed points of presence. At December 31, 2009, approximately 80.5% of Claro Participações subscribers were prepaid customers.

Claro Participações owns and operates cellular networks using GSM and UMTS/HSDPA digital technology. We
operate in Brazil under the PCS (Serviço Móvel Pessoal) regime. Claro Participações launched its GSM network in 2003 in certain major urban areas, and as of December 31, 2009, the GSM network
covered more than 3,290 cities and was used by 96.2% of Claro Participações wireless subscribers. We continue rolling out the GSM network with the goal of providing similar coverage as the Band A incumbent providers in the major
markets.

In addition, during the fourth quarter of 2007, we began offering 3G services in Brazil under our new
UMTS/HSDPA network. We continue the rollout of UMTS/HSDPA technologies in Brazil and by December 31, 2009, our UMTS/HSDPA network covered 391 towns, where approximately 54.8% of Brazils population resides. We were the first operator to
offer 3G services in Brazil. In order to rollout 3G services in Brazil, during the 2007 auction, we acquired 20 megahertz of additional spectrum in each of five regions and 30 megahertz of additional spectrum in each of six regions.

We have built our operations in Brazil through a number of transactions commencing in 2000 and ending with the acquisitions of operators
in the metropolitan area of São Paulo and in the states of Ceará, Piauí, Rio Grande do Norte, Paraiba, Pernambuco and Alagoas during 2003 and the acquisition of a license in the Minas Gerais region in 2005. In April 2005,
Stemar, a company owned by Claro, was awarded a license to operate wireless services in the Minas Gerais region. In September 2007, Claro acquired licenses to operate wireless services in the cities of Londrina and Tamarana (Paraná) and the
north region (Amazonas, Pará, Maranhão, Roraima and Amapá) in Brazil. At December 31, 2009, our two principal operating subsidiaries, Claro S.A. and Americel, had approximately 9,485 employees. We own all of our network
equipment in Brazil.

We operate in Brazil through two principal operating subsidiaries, Claro and Americel. Claro is licensed
to operate in the metropolitan area of São Paulo and in the states of Rio de Janeiro, Espírito Santo, São Paulo, Rio Grande do Sul, Santa Catarina, Paraná, Ceará, Piauí, Rio Grande do Norte, Paraiba,
Pernambuco, Alagoas, Bahia, Sergipe, Minas Gerais, Amazonas, Pará, Maranhão, Roraima and Amapá, and Americel in seven states in the central-west and northern regions of Brazil.

Through a number of holding companies we own more than 99.9% of the share capital of Claro S.A. and 99.3% of the share capital of
Americel. BNDESPar (the private equity arm of BNDES, the Brazilian development bank) holds approximately 0.03% and 0.62% of the share capital of Claro and Americel, respectively.

Sales and Distribution

Claro Participações markets its wireless services primarily through retail chains (approximately 8,521 points of sale) and
exclusive distributors (dealers) (approximately 3,056 points of sale) located throughout the regions

where it operates in Brazil. In the year ended December 31, 2009, approximately 55% of Claro Participações sales of handsets were generated by retail chains, 20% by
exclusive distributors (dealers) and approximately 5% from sales in company-owned stores, of which there are approximately 179. Claro Participações also sells and distributes its products and services over the Internet.

Claro Participações has implemented permanent training and evaluation programs for dealers to help maintain the level of
service quality.

Claro Participações company-owned retail stores offer one-stop shopping for a variety of
cellular services and products. Walk-in customers can subscribe for postpaid plans, prepaid plans, purchase prepaid cards and purchase handsets. Claro Participações stores serve as customer sales and service centers and Claro
Participações expects to continue to open new service centers as necessary in order to offer its products directly to subscribers in more effective ways.

Claro Participações has a corporate sales group to service the needs of its large corporate and other high-usage customers.

Billing and Collection

Claro Participações bills its postpaid customers through monthly invoices, which detail itemized charges such as usage,
services such as voicemail, and long-distance and roaming charges, in addition to applicable taxes. Customers may pay their bills with a credit card, through online banking, or in person at the post office or outlets of federal lottery houses(Casas Lotéricas).

If a postpaid customers payment is overdue, service may be suspended until the payment
for outstanding charges is received. If the subscribers payment is more than 60 days past due, service may be discontinued. Accounts that are more than 180 days past due are categorized as doubtful accounts together with all other accounts
related to the same client.

A prepaid customer who purchases a card has between 90 and 180 days from the date of activation
of the card to use the airtime. After such time, the customer can no longer use that airtime for outgoing calls unless the customer activates a new card. Sixty days after the card expires, unless the customer activates a new card, the balance on the
card, if any, is recognized as revenue.

Competition

Although the number of competitors has decreased primarily as a result of consolidation, competition in the Brazilian wireless industry is
substantial and varies by region. In addition to us, there are three other groups in Brazil with significant nationwide coverage. The largest is Vivo, a joint venture between Telefónica Móviles and Portugal Telecom. The joint venture
or one of its partners owns interests in some of the wireless companies that were created upon the breakup of Telebrás. The others are Telecom Italia Mobile (TIM) and Grupo Oi, which incorporated Brasil Telecoms operations, with
substantial government participation (49% through BNDES), becoming the largest fixed line operator and the fourth largest wireless operator. Other regional competitors are CTBC and Sercomtel. We also face competition from Nextel, a joint venture
between Motorola and Nextel Communications, Inc., for trunking services to the corporate segment in urban areas.

Since we
began providing 3G services in 2008, we also face competition in the broadband internet market from mobile companies that also offer 3G services as well as from other telecommunications companies and cable television operators, which were already
providing broadband internet access services through asymmetric digital subscriber line (ADSL) or cable technology.

Regulatory environment

Under the General Telecommunications Law (Lei Geral de Telecomunicações) an independent regulatory agency, Anatel,
regulates the telecommunications industry. Anatel has the authority to grant concessions and licenses for all telecommunications services, except for broadcasting services.

Beginning in 1997, there have been two cellular service providers in all markets in Brazil, one operating in subfrequency Band A and
another in subfrequency Band B. Since 1999, the entire Brazilian telecommunications sector has been open to competition.

In
September 2000, Anatel published guidelines for the implementation of PCS (Serviço Móvel Pessoal) operations in Brazil. Under the guidelines, Brazil is divided into three regions for PCS operations within the 1800 megahertz
frequency, as opposed to ten regions for the cellular service providers. All concessionaires in Brazil have migrated to the PCS regime. Upon migration to PCS, the Band A and Band B cellular providers have the right to apply for long distance
services licenses and are no longer subject to cellular regulations that restricted them from operating in more than two regions per Band. Regulations require that migrating companies adopt PCS service plans and provide for the establishment of
charges for the use of one operators network by another. During 2003, our operating companies in Brazil exchanged their original concessions for 15-year PCS authorizations. The 15-year period started from the time the original concessions were
granted, generally in 1997 or 1998. The operating companies may extend the term of the license for an additional 15 years, upon the payment of a fee.

The September 2000 guidelines also established rules regarding the selection of up to three additional wireless providers per region,
corresponding to Bands C, D and E. Beginning in February 2001, Anatel initiated a series of auctions through which it sold rights to D-Band and E-Band licenses. After canceling the auction of new licenses under the C-Band, Anatel implemented
procedures in May 2002 for the sale of C-Band bandwidth in installments not to exceed 50 megahertz per existing service provider, through which each of Claro Participações principal operating companies acquired bandwidth.

In December 2007, Anatel auctioned the remaining spectrum of Bands A, B, C, D, and E to existing service providers as
extension blocks. In this auction, we acquired spectrum to initiate operations in the northern region of Brazil (Amazonas, Pará, Maranhão, Amapá and Roraima) and in the cities of Londrina and Tamarana.

As part of Anatels plan to auction 3G licenses (in the 2100 megahertz spectrum), Anatel issued a resolution in 2006 increasing the
maximum overall spectrum permitted per operator from 50 megahertz to 80 megahertz. In December 2007, Anatel auctioned new 3G bands (Bands F, G, I and J in the 2100 megahertz spectrum) dividing Brazil into 11 regions. In that auction, we acquired 20
megahertz of additional spectrum in each of five regions and 30 megahertz of additional spectrum in each of six regions. Anatel imposed certain coverage obligations related to the purchase of additional spectrum to be fully-implemented during an
eight-year period. One of the more relevant obligations require the four main operators in Brazil to provide mobile services in every city where there is no current provider by 2010. Claro S.A. is responsible for 25% or 459 of the relevant cities
identified by Anatel. By the end of 2009, Claro S.A. had complied with the coverage of 269 cities, with the obligation to cover the remaining 190 in July 2010. If the coverage obligations assumed by Claro S.A. are not complied with, our operation
may suffer regulatory penalties.

In Brazil, rates for telecommunications services are regulated by Anatel. In general, PCS
licensees are authorized to increase basic plan rates only for inflation (less a factor determined by Anatel based on the productivity of each operator during the year) and on an annual basis. However, operators are allowed to create non-basic plans
(known as alternative plans) and modify them, without prior Anatel approval. Discounts from existing service plans, both basic and non-basic, are allowed without Anatel approval.

Currently, operators determine interconnection fees by agreement, subject to Anatel intervention only in case of disputes. On February
2005, Anatel commenced an arbitration proceeding against all mobile and fixed



47



---

##### Table of Contents

line operators in Brazil regarding the inflation adjustment applied by operators on the interconnection fees. The operators agreed on an interim price adjustment of 4.5% on mobile interconnection
fees. In 2006, the arbitration panel requested that the operators hire a consulting firm to analyze and recommend a resolution to the arbitration. Because operators could not agree on a single firm, two firms were hired and each presented a report
to Anatel. For the remaining proceedings, Anatel decided in 2009 to confirm the 4.5% interim adjustment. During 2007 and 2008, we entered into agreements with all mobile and some fixed operators in Brazil establishing interconnection fees. In 2009
we were unable to readjust interconnection fees as a result of Anatel determination that there should be no increase in the fixed to mobile public charges. As the mobile network termination fees are directly related to this charge, we were unable to
readjust the interconnection fees. During the first quarter of 2010, fixed operators increased public charges and, therefore, we were able to readjust our interconnection fees.

In 2009, interconnection fees were submitted to investigation by the Economic Defense Department under the allegation of price squeeze.

In the auction rules for 3G licenses published in 2007, it was established that, by October 2009, all service authorizations
terms should be unified under three major areas. During the last quarter of 2009, Anatel determined that interconnection fees should be submitted to negotiation between operators to establish a unified value. We expect that during 2010 we will reach
an agreement with other operators. Should the value be determined other that the average, we may suffer a financial impact.

In 2005, Anatel defined a series of cost-based methods, including the fully allocated cost methodology, for determining interconnection
fees charged by operators belonging to an economic group with significant market power. Anatel has not published all of the applicable regulations, but the implementation of the cost-based methodology is expected to take effect in 2010. In 2009,
mobile operators in Brazil provided Anatel with 2008 annual operating data. This information is intended to support Anatels future cost-based methods for determining interconnection fees. When these methods are ultimately implemented and if we
are deemed to be an economic group with significant market power, the revenues and results of operations of our Brazilian operations may be affected. Anatel had recently published a public consultation determining that economic groups with more than
20% of market share will be considered with significant market power only for purposes of interconnection fees. Should this proposal be approved, we are deemed to be an economic group with significant market power.

In July 2006, Brazilian regulators adopted a change in the interconnections regime relating to the methodology required for the
recognition of interconnection fees. Under the new methodology (full bill), we recognize interconnection revenues (and costs) on a gross basis, rather than on a net basis as required by the prior system (bill and keep).

In March 2007, Anatel issued a resolution establishing the portability of fixed and mobile numbers. Through this resolution, customers
have the option of retaining the fixed and mobile numbers if and when they change service providers within each state of Brazil. The implementation process of this resolution took two years, with national roll out that began in August 2008 in
certain cities and ended in March 2009. Anatel has nominated an independent entity, supported by mobile and fixed operators, to manage portability solicitations and has determined, through an administrative ruling, the maximum one-time fee to be
charged to a customer for the election to retain its number.

In 2007, Anatel issued a revision of the PCS rules which
revision came into effect in February 2008. Under the revised PCS rules, service providers are required to implement customer service centers in all regions of Brazil with more than 100,000 inhabitants, charge only for delivered SMS messages and
reimburse unused prepaid credits. Other main changes to the PCS rule include the regulation of the duration of contracts with a given operator (maximum of 12 months per contract) and the right of customers to change service plans with the same
operator without penalties.

##### Table of Contents

In 2008, Anatel approved the General Regulatory Plan (or PGR) which identifies significant
issues in the telecom industry and sets forth a timetable for future regulations. The PGR included Anatels plans within the next two years to regulate MVNO (Mobile Virtual Network Operators) practices, expand broadband services to rural and
low-income areas and implement rules related to fixed incumbents infrastructure usage. Regulation of MVNO is expected to be published in 2010.

Anatel has also shown intention to organize several auctions in 2010 in connection with the remaining available spectrum in the 2,100,
1,900, 1,800, 900 and 850 MHz frequencies, and 3.5GHz frequencies (3,400 to 3,600 MHz). It is also expected that Anatel will allocate the 2.5GHz (2,500 to 2,690 MHz) frequency by the end of 2010.

more than 304,000 virtual points of sale. Comcels strategy is to continue to expand its customer base through the build-out of its network.

At December 31, 2009, Comcel had 3,910 employees.

In each of the three regions of Colombia, we compete with Telefónica Móviles and Colombia Móvil, a consortium
acquired by Millicom in 2006. Colombia Móvil started nationwide commercial operations in November 2003. Comcel also competes with traditional fixed-line telephone service operators. In addition, Comcel faces competition from alternative
wireless services, including mobile radio and paging services, rural wireless operators and trunking services. These competing wireless services are widely used in Colombia as a substitute for fixed-line services.

The Ministry of Communications and the CRC are responsible for regulating and overseeing the telecommunications sector, including
cellular operations. The Ministry of Communications, which granted the cellular concessions in 1994, supervises and audits the performances of the concessionaires legal and contractual obligations. The activities of Comcel are also supervised
by the Colombian Superintendency of Industry and Commerce (Superintendencia de Industria y Comercioor SIC), which enforces antitrust regulations, promotes free competition in the marketplace and protects consumer rights.

In September 2009, the CRC issued a series of resolutions stating that Comcel has a dominant position in Colombias
market for outgoing mobile services. Under Colombian law, a market participant is considered to have a dominant position in a specified market if the regulators determine that it has the capacity to control the conditions in that market. The CRC
made its determination based on Comcels traffic, revenues and subscriber base. The resolutions also included regulations that would require Comcel to charge rates (excluding access fees) for mobile-to-mobile calls outside the Comcel network
(off net) that are no higher than the fees charged for mobile-to-mobile calls within the Comcel network (on net) plus access fees. The regulations were first implemented on December 4, 2009 and Comcel does not expect
them to have a material impact on its business and results of operations in Colombia. See Legal ProceedingsComcel Dominant Position under Item 8.

Comcel holds ten-year concessions, acquired in 1994, to provide wireless telecommunications services in the eastern, western and
Caribbean regions of Colombia. Under the terms of the concessions, Comcel is required to make quarterly royalty payments to the Ministry of Communications based on its revenues. Under the terms of an agreement entered into in March 2004, the
Ministry of Communications agreed to renew Comcels concessions through 2014.

networks and third generation technology. We expect to spend approximately 15.0% of our budgeted capital expenditures in Mexico and the United States, 59.0% in South America, 13.0% in Central America and 13.0% in the Caribbean.

We expect to finance our capital expenditures for 2010 with funds generated from operations and, depending on market conditions and our
other capital requirements, new debt financings.



|Item 5. | Operating and Financial Review and Prospects
|------- | --------------------------------------------

The following discussion should be read in conjunction with our audited consolidated financial statements and the notes thereto included
in this annual report. Our financial statements have been prepared in accordance with Mexican FRS, which differs in certain respects from U.S. GAAP. Note 21 to our audited consolidated financial statements provides a description of the principal
differences between Mexican FRS and U.S. GAAP, as they relate to us, a reconciliation to U.S. GAAP of income and total shareholders equity, a description of how operating income under U.S. GAAP was determined and cash flow statements for the
years ended 2008 and 2009 under U.S. GAAP.

Under Mexican FRS, our financial statements for periods ending prior to
January 1, 2008 recognized the effects of inflation on financial information. Inflation accounting under Mexican FRS had extensive effects on the presentation of our financial statements through 2007. See Inflation Accounting under
this Item 5 and Note 2(f) to our audited consolidated financial statements.

The following discussion analyzes certain
operating data, such as average revenues per subscriber (also referred to as ARPU), average minutes of use per subscriber (also referred to as average MOUs per subscriber) and churn rate, that are not included in our
financial statements. We calculate ARPU for a given period by dividing service revenues for such period by the average number of subscribers for such period. The figure includes both prepaid and postpaid customers. We calculate churn rate as the
total number of customer deactivations for a period divided by total subscribers at the beginning of such period.

##### Table of Contents

We provide this operating data because it is regularly reviewed by management and because
management believes it is useful in evaluating our performance from period to period. We believe that presenting information about ARPU and MOUs is useful in assessing the usage and acceptance of our products and services, and that presenting churn
rate is useful in assessing our ability to retain subscribers. This additional operating information may not be comparable with similarly titled measures and disclosures by other companies.

We count our wireless subscribers by the number of lines activated. We continue to count postpaid subscribers for the length of their
contracts. We disconnect, or churn, our postpaid subscribers at the moment they voluntarily discontinue their service or following a prescribed period of time after they become delinquent. We disconnect our prepaid subscribers after a
period of four months after they discontinue using our service, so long as they have not activated a calling card or received traffic. We calculate our subscriber market share by comparing our own subscriber figures with the total market subscriber
figures periodically reported by the regulatory authorities in the markets in which we operate. We understand that these regulatory authorities compile total market subscriber figures based on subscriber figures provided to them by market
participants, and we do not independently verify these figures.

Inflation Accounting

Through the end of 2007, Mexican FRS required us to recognize effects of inflation in our financial statements. They also required us to
present financial statements from prior periods in constant pesos as of the end of the most recent period presented. We present financial information for 2008 and 2009 in nominal pesos and financial information for 2007 and prior years in constant
pesos as of December 31, 2007.

Cessation of Inflation Accounting under Mexican FRS

Mexican FRS changed beginning on January 1, 2008, and the inflation accounting methods no longer apply, except where the economic
environment qualifies as inflationary for purposes of Mexican FRS. The environment is inflationary if the cumulative inflation rate equals or exceeds an aggregate of 26% over three years (equivalent to an average of 8% in each year).
Based on current forecasts, we do not expect the Mexican economic environment to qualify as inflationary in 2010, but that could change depending on actual economic performance.

Changes in Mexican FRS

Note 2z.3 to our audited consolidated financial statements discusses new accounting pronouncements under Mexican FRS that came into force
in 2009 and that will come into force in 2010. The pronouncements that became effective on January 1, 2009 were fully implemented in the financial statements included in this annual report. In 2010, other pronouncements might affect certain
aspects of our financial statements. The 2009 accounting pronouncements were applied on a prospective basis and prior years financial statements have not been adjusted. As a result, our financial statements for 2009 may not be comparable to
our financial statements for prior years.

Transition to IFRS

Beginning with the year ended December 31, 2012, Mexican issuers with securities listed on a Mexican securities exchange will be
required to prepare financial information in accordance with IFRS as issued by the IASB. Issuers may voluntarily report using IFRS before the change in the reporting standards becomes mandatory. We have begun presenting financial statements in
accordance with IFRS for the fiscal year ended December 31, 2010.

Overview

Trends in Operating Results

We have experienced significant growth in our operating revenues (14.2% in 2009, 10.9% in 2008 and 28.2% in 2007) and operating income
(9.1% in 2009, 12.2% in 2008 and 39.6% in 2007) in recent years.Besides acquisitions, the principal factors affecting our operating revenues and operating income relate to growth in subscribers and traffic. Traffic can grow as a result of
increased usage by existing customers or as a result of subscriber growth or both. In recent years, we have experienced a significant increase in the usage of value-added services, such as data services.

We have generally experienced both increased usage and subscriber growth in recent periods. Due principally to competitive pressures, we
generally have not increased prices in recent periods. In many of our markets, we have introduced promotions and discount packages that tend to result in higher MOUs and lower ARPU. In addition, interconnection rates have been reduced in many of our
markets. During 2009, for example, interconnection rates in Mexico, Colombia and Chile declined by 10%, 50% and 40%, respectively, as compared to 2008 levels. We expect the trend of declining prices to slow in 2010, but we also expect pressure on
ARPU as a result of the economic crisis. Traffic increases may not continue to fully offset further price or rate declines, which may adversely affect our revenues and operating income.

At December 31, 2009, we had approximately 201.0 million wireless subscribers, as compared to 182.7 million at
December 31, 2008, a 10.0% increase. During 2008, we experienced a 29.3 million or 19.1% increase in wireless subscribers. During 2007, we experienced a 28.6 million or 23.0% increase in wireless subscribers. Subscriber growth during
2009, 2008 and 2007 was substantially attributable to organic growth rather than acquisitions of new companies. We experienced wireless subscriber growth in every segment, with the largest amounts attributable to Brazil (5.7 million net new
subscribers, or 31.07% of total net new subscribers), the United States (3.2 million net new subscribers, or 17.73% of total net new subscribers), Mexico (2.8 million net new subscribers, or 15.32% of total net new subscribers) and the Southern Cone
(2.2 million net new subscribers, or 12.1% of total net new subscribers). The rate of organic growth in subscribers was adversely affected by the recent economic crisis. However, the South American economies recovered faster than we expected. This
recovery resulted in faster subscriber growth in these markets and allowed us to meet our target for subscriber growth in 2009.

We believe that many of the markets we serve provide opportunities for continued growth; and as subscribers and traffic increase, we
generally expect to report higher revenue and operating income (before depreciation and amortization) as a result of economies of scale. These effects can be partly or wholly offset, however, by the effects of competition on prices and subscriber
acquisition costs. Our operating margins, particularly in certain geographic segments, have tended to decline during periods of accelerated subscriber growth because of the costs of acquiring new subscribers, which include subsidies for equipment
purchases and activation commissions. As our subscriber base grows and new subscribers represent a lower fraction of our subscriber base, our operating margins have generally improved, although we cannot give assurances that this improvement will
continue.

We have launched and are actively promoting 3G and value-added services in all of our markets (excluding TracFone).
The introduction of 3G services in our markets contributed to an increase of 31.1%, 24.1% and 19.8% in data revenues in 2007, 2008 and 2009, respectively. Data revenues accounted for 18.1% of service revenues in 2009, as compared to 13.5% in 2008
and 12.4% in 2007. We expect that data revenues as a percentage of our service revenues will continue to increase as 3G services are more widely adopted.

Market and competitive conditions differ considerably in the markets in which we operate, and these conditions are sometimes subject to
rapid change.

Effects of Recent Business Acquisitions

During 2007 and 2008, we made significant acquisitions. The consolidation of these companies affects the comparability of our recent
results. We accounted for all of these acquisitions using the purchase method, and the results of each acquired company were consolidated in our financial statements as from the month following the consummation of its acquisition. Our audited
consolidated financial statements reflect the consolidation of these companies as follows:



| |  |  | Telecomunicaciones de Puerto Rico, Inc. (from April 2007);
| | - |  | ----------------------------------------------------------



| |  |  | Oceanic Digital Jamaica Limited (from December 2007); and
| | - |  | ---------------------------------------------------------



| |  |  | Estesa Holding Corp. (from September 2008).
| | - |  | -------------------------------------------

There were no significant acquisitions in 2009.

Geographic Segments

We have operations in 18 countries, which are grouped for financial reporting purposes in nine geographic segments. Segment information is
presented in Note 19 to our audited consolidated financial statements included in this annual report. Mexico is our largest single geographic market, accounting for 36.0% of our total operating revenues in 2009 and 29.4% of our total wireless
subscribers at December 31, 2009. The percentage of our total operating revenues represented by Mexico decreased in 2009, as a result of acquisitions outside Mexico and faster organic revenue growth outside Mexico. We expect that our
non-Mexican operations will continue to grow faster than Mexico, though exchange rate variations may affect the comparison in any given year.

Brazil is our second most important market in terms of revenues and subscribers, accounting for 20.9% of our total operating revenues in
2009 and 22.1% of our total wireless subscribers at December 31, 2009. We have made significant investments in Brazil in recent periods, through acquisitions and expansions of our networks, and the importance of our Brazilian operations has
increased significantly with respect to our overall results.

Our Colombian and Panamanian operations have experienced
accelerated subscriber growth in recent years; and, as a result, Colombia has become our third largest market in terms of revenues (9.4% in 2009) and subscribers (13.8% in 2009).

The table below sets forth the percentage of our revenues and total wireless subscribers represented by each of our operating segments
for the periods indicated.

##### Table of Contents

Our subsidiaries report significantly different operating margins. In 2009, Mexico reported
operating margins higher than our consolidated operating margin, while the other segments reported lower operating margins.

Factors that drive financial performance differ for our operations in different countries, depending on subscriber acquisition costs,
competitive situation, regulatory environment (including fees and revenue-based payments related to our concessions), economic factors, interconnection rates, capital expenditures requirements, debt profile and many other factors. Accordingly, our
results of operations in each period reflect a combination of different effects in the different countries.

In recent years,
we have experienced faster growth in our postpaid subscriber base than in our prepaid subscriber base, due in part to the quality of coverage and service and the technological platforms that allow us to offer more variety in data services. In 2009,
Mexico, the Dominican Republic and the Caribbean reported postpaid subscriber increases that significantly exceeded those reported in 2008.

Effects of Economic Conditions and Exchange Rates

Our results of operations are affected by economic conditions in Mexico, Brazil, Colombia and the other countries in which we operate. The
current recessionary environment in every country in which we operate may also impact our results of operations. In periods of slow economic growth, demand for telecommunications services tends to be adversely affected.

Effects of Exchange Rates

Our results of operations are affected by changes in currency exchange rates. As discussed above, currency variations between the Mexican
peso and the currencies of our non-Mexican subsidiaries, especially the Brazilian real, may affect our results of operations as reported in Mexican pesos.

Changes in the value of the various operating currencies of our subsidiaries against the U.S. dollar also result in exchange losses or
gains on our net U.S. dollar-denominated indebtedness and accounts payable. Appreciation of these currencies against the U.S. dollar generally results in foreign exchange gains, while depreciation of these currencies against the U.S. dollar
generally results in foreign exchange losses. We recorded foreign exchange gains of Ps. 4,557 million in 2009. We recorded foreign exchange losses of Ps. 13,686 million in 2008 and foreign exchange gains of Ps. 2,463 million in 2007.
Changes in exchange rates also affect the fair value of derivative instruments that we use to manage our currency risk exposures. We recognized Ps. 732 million in fair value losses on derivatives in 2009.

Offers for Telmex Internacional and CGT

On January 13, 2010, we announced that we intend to conduct two separate but concurrent offers to acquire outstanding shares of
Telmex Internacional and CGT. Telmex Internacional provides a wide range of telecommunications services in Brazil, Colombia and other countries in Latin America. CGT is a holding company with controlling interests in Telmex Internacional and Telmex,
a leading Mexican telecommunications provider. If the offers are completed, we will acquire controlling interests in CGT, Telmex Internacional (directly and indirectly through CGT) and Telmex (indirectly through CGT). The principal purpose of the
offers is to pursue synergies between our business and that of Telmex Internacional.

The completion of the offers will be
subject to satisfaction of certain conditions. It is possible that if not all such conditions are obtained or met we will not complete the offers. Accordingly, there can be no assurance as to whether or when the offers will be completed.

Effects of Regulation

We operate in a regulated industry. Although currently we are free to set end prices to our wireless customers, our results of operations
and financial condition have been, and will continue to be, affected by regulatory actions and changes. In recent periods, for example, regulators have imposed or promoted decreases to interconnection rates, and we expect further decreases in
interconnection rates in Mexico, Chile and Colombia. Lower interconnection revenues have often been offset by increased traffic resulting from lower effective prices to customers, but this may change.

In addition, some jurisdictions may impose specific regulations on wireless carriers that are deemed dominant. Although we are not
currently subject to any regulations or restrictions as a result of our market position, we are one of the subjects in ongoing general market investigations in Mexico to ascertain whether one or more cellular operators have substantial market power
in one or more sectors of the telecommunications industry. In November 2008, Cofeco issued a preliminary report (dictamen preliminar) finding that Telcel has substantial market power. The preliminary report was confirmed by the publication on
February 10, 2010 in the Official Gazette of the relevant findings of a resolution relating to the existence of substantial market power in the nationwide market for voice services. In February 2010, Telcel filed an administrative proceeding
(recurso administrativo de reconsideración) before Cofeco. When this administrative proceeding was rejected by Cofeco for analysis, Telcel filed an appeal (amparo indirecto) before an administrative judge against the rejection
of the proceeding and against the issuance, subscription and publication of the February 10, 2010 resolution. Under the Antitrust Law and the Federal Telecommunications Law, if Cofeco makes a final finding of substantial market power concerning
an operator, Cofetel can impose on that operator specific regulations with respect to tariffs, quality of service and information. We cannot predict what regulatory steps Cofetel may take in response to determinations by Cofeco.

In September 2009, the CRC issued a series of resolutions stating that our Colombian subsidiary, Comcel, has a dominant position in
Colombias market for outgoing mobile services. Under Colombian law, a market participant is considered to have a dominant position in a specified market if the regulators determine that it has the capacity to control the conditions in that
market. The CRC made its determination based on Comcels traffic, revenues and subscriber base. The resolutions also included regulations requiring Comcel to charge rates (excluding access fees) for mobile-to-mobile calls outside the Comcel
network (off net) that are not higher than the fees charged for mobile-to-mobile calls within the Comcel network (on net) plus access fees. The regulations were first implemented in December 4, 2009. These regulations
will limit our flexibility in offering pricing plans to our customers, but we cannot predict the effects on our financial performance.

Composition of Operating Revenues

Most of our operating revenues (88.5% in 2009) is comprised of service revenues. Of our service revenues, the largest portion (34.0% in
2009) is from airtime charges for outgoing calls. We also derive a significant portion of our revenues from interconnection charges billed to other service providers for calls completed on our network. The primary driver of usage charges (airtime
and interconnection charges) is traffic, which, in turn, is driven by the number of customers and by their average usage. Postpaid customers generally have an allotment of airtime each month for which they are not required to pay usage charges.
Service revenues also include (1) monthly subscription charges paid by postpaid customers, (2) long-distance charges and (3) charges for value-added and other services, such as roaming, call forwarding, call waiting, call blocking and
short text messaging.

Revenues from sales of prepaid services are deferred and recognized as airtime is used or when it
expires, and are included under usage charges. Monthly basic rent under post-paid is billed in arrears based on the plan



66

##### Table of Contents

and package rates approved and correspond to services rendered, except in Mexico and Colombia, where basic monthly rent is billed one month in advance. Revenues are recognized at the time
services are provided. Billed revenues for the service not yet rendered are recognized as deferred revenues.

We also have
sales revenues from selling handsets and other equipment. Most of our new subscribers purchase a handset, and although we also sell new handsets to existing customers, changes in sales revenues are driven primarily by the number of new customers.
The pricing of handsets is not geared primarily to making a profit from handset sales, because it also takes into account the service revenues that are expected to result when the handset is used.

Seasonality of our Business

Our business has been subject to a certain degree of seasonality, characterized by a higher number of new clients during the fourth
quarter of each year. We believe seasonality is mainly driven by the Christmas shopping season.

Consolidated Results of Operations

Operating Revenues

Operating revenues increased by 14.2% in 2009. The Ps. 49,056 million total increase was attributable to increases in service
revenues (Ps. 50,988 million), partially offset by a decrease in equipment revenues (Ps. 1,932 million). We experienced subscriber growth in all of our markets for wireless services.

Service revenues increased by 17.1% in 2009. The total increase of Ps. 50,988 million in service revenues is principally due to
increased traffic and subscriber growth (Ps. 23,792 million, or 8.0% of the increase) reflecting a significant increase in the usage of value added services and to exchange rate variations (Ps. 27,196 million, or 9.1% of the increase)
primarily attributable to the appreciation of the Brazilian real and the Colombian peso against the Mexican peso.

Equipment
revenues decreased by 4.1% in 2009, from Ps. 47,505 million to Ps. 45,573 million. This decrease primarily reflects a decrease in the average selling price of handsets. Equipment revenues as a percentage of total revenues decreased from
13.7% in 2008 to 11.5% in 2009.

In 2008, our operating revenues increased by Ps. 34,075 million, or 10.9%, compared to
2007. The total increase of Ps. 31,813 million in service revenues reflects principally increased traffic and subscriber growth (Ps. 28,122 million), as our wireless subscriber base increased by 19.1%. The balance of the increase in
service revenues reflects increases due to exchange rate variation (Ps. 7,021 million) and to the effect of consolidating Puerto Rico for the full year (Ps. 3,039 million), offset in part by the effect of inflation accounting on 2007
revenues (Ps. 6,370 million). This was partly offset by lower ARPU attributable principally to promotions and discount packages, lower interconnection rates in some markets and a growing proportion of prepaid subscribers, who generate less
revenue per line than postpaid subscribers.

Equipment revenues accounted for Ps. 2,261 million, or 6.6%, of the
Ps. 34,075 million increase in operating revenues in 2008. This primarily reflects subscriber growth. Equipment revenues as a percentage of total revenues decreased from 14.5% in 2007 to 13.7% in 2008.

Operating Costs and Expenses

Cost of sales and servicesCost of sales and services represented 41.8% of operating revenues in 2009, 42.2% of operating
revenues in 2008 and 42.5% of operating revenues in 2007. In absolute terms, cost of sales and services increased by 13.0% in 2009 and 10.3% in 2008, due principally to increases in interconnection rates, infrastructure rental costs, network
maintenance costs and radio base station rental costs.



67



---

##### Table of Contents

Cost of sales was Ps. 76,187 million in 2009 and Ps. 75,117 million in 2008 and
primarily represents the cost of handsets sold to subscribers. Costs of handsets increased by 1.4% in 2009 and by 7.3% in 2008 and exceeded our revenues from the sale of handsets by 40.0% during 2009 and 36.7% during 2008, since we subsidize the
cost of handsets for new subscribers.

Cost of services increased by 25.3% in 2009 to Ps. 17,945 million. This increase in
cost of services was greater than the growth in service revenues, which increased by 17.1% in 2009. Cost of services increased faster than service revenues primarily due to increases in revenue-based concession payments in Mexico, the fee for
renewal of our concession in Ecuador, infrastructure costs, employee salary increases and infrastructure maintenance costs. Cost of services increased by 13.6% in 2008 compared to 2007, while service revenues increased by 11.9% during the same
period.

Commercial, administrative and generalCommercial, administrative and general expenses represented 18.3%
of operating revenues in 2009, 18.0% of operating revenues in 2008 and 17.2% of operating revenues in 2007. On an absolute basis, commercial administrative and general expenses increased by 16.1% in 2009 and 16.3% in 2008. The increase in
commercial, administrative and general expenses in 2009 principally reflects higher advertising expenses, higher commissions paid to our distributors, establishment of new customer service centers and an increase in our uncollectible accounts.

Telcel, like other Mexican companies, is required by law to pay to its employees, in addition to their agreed compensation
and benefits, profit sharing in an aggregate amount equal to 10% of Telcels taxable income. Conecel, our Ecuadorian subsidiary, and Claro Peru, our Peruvian subsidiary, are also required to pay employee profit sharing at a rate of 15% of
Conecels and 10% of Claro Perus taxable income. We recognize these amounts under commercial, administrative and general expenses.

Depreciation and amortizationDepreciation and amortization increased by 27.1% in 2009 and 3.4% in 2008. As a percentage of
revenues, depreciation and amortization increased from 12.1% in 2008 to 13.4% in 2009. The increases in depreciation and amortization in 2009 and 2008 reflect the substantial investments made in our networks and a charge of Ps. 4,462 million in
2009 and of Ps. 1,996 million in 2008, in each case due to the shortening of the useful life of certain GSM assets in Brazil in 2009.

Operating Income

Operating income increased by 9.1% in 2009 and 12.2% in 2008. Operating income in 2009 reflects a charge of Ps. 4,462 million due to
the shortening of the useful life of certain plants and equipment in Brazil. Absent this additional depreciation charge in Brazil, our operating income during 2009 would have increased by 11.4% in 2009.

All of our segments reported operating income in 2009.Operating margin (operating income as a percentage of operating revenues)
was 26.4% in 2009, 27.6% in 2008 and 27.3% in 2007. The decrease in our operating margin in 2009 is due principally to the increased depreciation costs in Brazil and an increase in indirect taxes, including taxes on our concessions, local taxes and
employee profit sharing. Improvement in our operating margin in 2008 reflected principally the increase in service revenues.

Comprehensive Financing Cost

Under Mexican FRS, comprehensive financing cost reflects interest income, interest expense, foreign exchange gain or loss and other
financing costs. Through 2007, comprehensive financing cost also included gain or loss attributable to the effects of inflation on monetary assets and liabilities.

We had comprehensive financing cost of Ps. 2,982 million in 2009, as compared to comprehensive financing cost of Ps. 13,865
million in 2008 and Ps. 387 million in 2007. The decrease in comprehensive

##### Table of Contents

financing cost in 2009 reflects principally (a) a 12.5% decrease in net interest expense due to a decrease in net debt, (b) foreign exchange gains of Ps. 4,557 million due
principally to the appreciation of the Mexican peso against the U.S. dollar and (c) a decrease in net other financing costs, primarily due to fair value losses of our derivative financial instruments, commissions and stock exchange registration
and listing costs.

The increase in financing cost in 2008 reflects principally (a) foreign exchange losses of
Ps. 13,686 million due principally to the depreciation of the Mexican peso against the U.S. dollar, (b) net other financing income of Ps. 6,358 million, primarily due to fair value gains on currency derivatives and (c) no
monetary gains or losses in 2008, due to the cessation of inflation accounting under Mexican FRS, as compared to a monetary gain of Ps. 5,038 million in 2007.

For 2009, 2008 and 2007, changes in the components of financing cost were as follows:



| |  |  | Net interest expense decreased by 12.5% in 2009 and increased by 38.0% in 2008. The decrease in 2009 was primarily attributable to a decrease in our
consolidated net debt. The increase in 2008 was primarily attributable to increased net debt resulting from increased capital expenditures.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We had a net foreign exchange gains of Ps. 4,557 million in 2009, compared to a loss of Ps. 13,686 million in 2008 and a gain of
Ps. 2,463 million in 2007. The foreign exchange gain in 2009 was primarily attributable to the 3.5% appreciation of the Mexican peso against the U.S. dollar. The foreign exchange loss in 2008 was primarily attributable to the depreciation of
the Mexican peso against the U.S. dollar and was partly offset by gains on currency derivatives described below. The foreign exchange gain in 2007 was primarily attributable to appreciation of the Mexican peso against the US. dollar and of the
Brazilian real and the Colombian peso against the Mexican peso and the U.S. dollar.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | In 2009 and 2008, following the cessation of inflation accounting under Mexican FRS, we did not record monetary gains or losses. In 2007, we reported a
Ps. 5,038 million net monetary gain, as compared to Ps. 3,848 million in 2006. The increase in 2007 was primarily related to higher inflation in many of our markets, as well as an increase in our average net indebtedness. See
Inflation Accounting under this Item 5.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We reported a net other financing loss of Ps. 1,820 million in 2009, compared to a gain of Ps. 6,358 million in 2008 and a loss of
Ps. 3,153 million in 2007. Net other financing costs include fair value gains and losses of financial instruments, commissions, fair value gains and losses on the sale of investments. In 2009, our net other financing cost was principally
attributable to fair value losses of our financial instruments and commissions. In 2008, our net financing income was principally attributable to a net fair value gain on our currency derivatives of Ps. 7,497 million. In 2007, our net financing
costs were principally attributable to the write-off of our investment in U.S. Commercial Corp. and fair value gain on our derivative instruments.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We capitalized financing cost of Ps. 1,627 million in 2009, Ps. 7,054 million in 2008 and Ps. 1,158 million in 2007, in each case
related to construction of our plant, property and equipment.

Income Tax

Our effective rates of provisions for corporate income tax as a percentage of pretax income were 22.4%, 25% and 27.7% for 2009, 2008 and
2007, respectively. Our effective rate in 2009 and 2008 includes the partial reversal of the valuation allowance corresponding to tax losses in Brazil. The statutory rate of Mexican corporate income tax was 28% in 2009, 2008 and 2007.

In 2008, Mexico introduced a new flat rate business tax (Impuesto Empresarial a Tasa Única, or
IETU). IETU is calculated by reference to the income derived from the transfer of goods, the lease of assets and the rendering of services. The rate for 2008 and 2009 was 16.5% and 17%, respectively. Hereafter, the rate will be 17.5%.

Other Expense, Net

In 2009, we recorded net other expense of Ps. 2,166 million in 2009, compared to net other expense of Ps. 2,327 million in 2008
and Ps. 3,713 million in 2007. The expense in 2009 reflects principally other net financing costs and other non-operating costs. The expense in 2008 reflects principally an impairment of goodwill in Honduras and the accrual for interest and
penalties for certain tax contingencies in Brazil. The expense in 2007 reflects principally our decision to discontinue the use of certain time division multiple access (or TDMA) equipment in Colombia and Ecuador.

Equity in Results of Affiliates

Our proportionate share of the results of equity-method affiliates resulted in income of Ps. 196 million in 2009, Ps. 109
million in 2008 and Ps. 58 million in 2007. The income in 2009, 2008 and 2007 reflect principally our share of the income reported by Grupo Telvista, S.A. de C.V., a Mexican sociedad anónima de capital variable.

Net Income

We had majority net income of Ps. 76,913 million in 2009, Ps. 59,486 million in 2008 and Ps. 58,588 million in 2007. The
increase in net income in 2009 reflects principally the Ps. 8,663 million increase in operating income and a significant reduction (Ps. 10,884 million) in our comprehensive financing cost. The increase in net income in 2008 principally reflects
our increase in operating income, which was substantially offset by an increase in our exchange losses. The increase in net income in 2007 principally reflects our increased operating income, which was partially offset by an increase in our income
tax expense.

Results of Operations by Geographic Segment

We discuss below the operating results of our subsidiaries that provide telecommunication services in our principal markets. All amounts
discussed below are presented in accordance with Mexican FRS. Note 2(a)(ii) to our audited consolidated financial statements included in this annual report describes how we translate the financial statements of our non-Mexican subsidiaries. Exchange
rate changes between the Mexican peso and those currencies affect our reported results in Mexican pesos and the comparability of reported results between periods.

The following table sets forth the exchange rate used to translate the results of our significant non-Mexican operations, as expressed in
Mexican pesos per foreign currency unit, and the change from the rate used in the prior year.

Mexico

Operating revenues in Mexico increased by 5.2% in 2009 and 6.4% in 2008, benefiting from subscriber growth and increases in traffic.
Service revenues increased by 9.3% in 2009 and 6.3% in 2008, reflecting growth in revenues from value-added, airtime and long distance services, partially offset by a decrease in interconnection revenues due to lower interconnection fees that were
not compensated by volume. Equipment revenues in Mexico decreased by 6.5% in 2009 and increased by 7.4% in 2008, principally due to a reduction in the average sales price of handsets. The number of subscribers in Mexico increased by 5.0% in 2009 and
12.7% in 2008.

Average MOUs per subscriber increased by 11.3% in 2009 and 21.7% in 2008. ARPU decreased by 1.2% in 2009 and
7.5% in 2008. During both years, we lowered the price of some of our services through new commercial plans and promotions, which contributed to the increase in subscribers and MOUs but had a negative impact on ARPU. In addition, in 2008 and 2009,
our ARPU was negatively affected by lower interconnection rates and an increase in the share of our total traffic represented by data services, such as SMS messaging and other 3G services, which on average generate lower revenues per minute of use
than voice services. Reductions in interconnection tariffs also resulted in lower interconnection revenues. The churn rate for our Mexican operations was 3.2% in 2009, 3.3% in 2008 and 3.4% in 2007.

Operating income increased by 10.6% in 2009 and 4.6% in 2008. Our operating margin was 48.2% in 2009 and 45.8% in 2008. The increase in
our operating margin in 2009 is due principally to an increase in our operating revenues and the implementation of strict controls in our operating costs and expenses, which remained unchanged as a percentage of our operating revenues. In 2008,
operating margin decreased, reflecting an increase in cost and expenses principally due to equipment subsidies, uncollectible accounts and employee profit sharing, which was greater than the increase in operating revenues in that year. Finally,
depreciation and amortization expenses of our Mexican operations as a percentage of its operating revenues increased slightly from 6.2% in 2008 to 6.5% in 2009.

For Mexico, the financial information set forth in Note 19 to our audited financial statements includes revenues and costs from group
corporate activities, such as licensing fees and group overhead expenses. The discussion above refers to our operating results in Mexico and excludes the results of our group corporate activities.

Brazil

Operating revenues in Brazil increased by 16.8% in 2009 and 20.9% in 2008. The increase in 2009 was primarily attributable to the
appreciation of the Brazilian real against the Mexican peso as well as an increase in traffic and subscriber growth. The number of our subscribers in Brazil increased by 5.7 million subscribers in 2009 to approximately 44.4 million
subscribers as of December 31, 2009. The increase in operating revenues in 2008 was primarily attributable to increased traffic and subscriber growth and data revenue. The 6% appreciation of the Brazilian real against the Mexican peso in 2008
also contributed to the increase in operating revenues in 2008, as 6.9% of the 20.9% was due to currency effects. The number of subscribers increased by 8.5 million subscribers in 2008 to approximately 38.7 million subscribers.

Average MOUs per subscriber decreased by 9.4% in 2009 and increased by 20.7% in 2008. ARPU decreased by 0.3% in 2009 and 3.1% in 2008.
Calculated in nominal Brazilian reais, ARPU decreased by 8.0% in 2009 and 7.4% in 2008. The decrease in average MOUs and ARPU during 2009 reflects a significant increase in the use of data services as compared to voice (airtime and long distance)
services. The increase in average MOUs during 2008 as well as the decrease in ARPU during 2008 reflects the impact on traffic of our lowering of prices through new commercial plans and promotions for our 3G services. Our churn rate was 2.8% in 2009
and 2.7% in 2008.

Operating income decreased by 13.7% in 2009 and increased by 161.0% in 2008. Operating income in 2009 and
2008 reflects primarily the effect of higher depreciation expense resulting from the shortening of the useful

lives of certain GSM and TDMA assets in 2009 and 2007 as compared to 2008. In 2009, the depreciation expense resulting from the shortening of the useful lives of certain GSM assets was Ps. 4,462
million. The depreciation expense in 2008 relating to GSM and TDMA assets was Ps. 1,996 million. Operating margin (1.7% in 2009 and 2.2% in 2008) continues to be affected by a high level of depreciation and amortization expenses relative to revenues
due to the significant costs incurred to deploy networks. Absent these depreciation expenses, the operating margin would have been 5.1% in 2008 and 7.1% in 2009. Depreciation and amortization expenses represented 22.5% of our operating revenues in
2009 and 21.4% in 2008.

Southern ConeArgentina, Chile, Paraguay and Uruguay

Our operating revenues in Argentina, Chile, Paraguay and Uruguay increased by 21.6% in 2009 and 12.1% in 2008. The increase in 2008 and
2009 was attributable primarily to subscriber growth. The number of subscribers increased by 2.2 million subscribers in 2009 to approximately 21.8 million subscribers at year-end. Since 2007, our postpaid subscriber base has grown at a
faster rate than our prepaid subscriber base. The currency effects between the Argentine peso and the Mexican peso did not have a significant effect on our operating revenues in 2009 and 2008.

Average MOUs per subscriber increased by 9.2% in 2009 and 2.3% in 2008. ARPU increased by 8.5% in 2009 and decreased by 4.8% in 2008.
Expressed in nominal local currencies, ARPU increased in 2009 by 5.9% in Argentina, 52% in Paraguay and 4% in Uruguay and decreased by 15% in Chile. In 2008, ARPU increased by 3.0% in Argentina and 11.7% in Paraguay and decreased by 10.0% in Uruguay
and 7.3% in Chile. The increase in MOUs in 2009 principally reflected reflects an increase in our airtime traffic and a significant increase in traffic and revenues from data and value-added services. The increase in MOUs in 2008 principally
reflected a decrease in prices due to promotions and airtime subsidies including free calls to friends and family. Our churn rate remained stable at 2.6% in 2008 and 2009.

Operating income increased by 32.9% in 2009 and 112.0% in 2008. This increase in 2009 reflected an increase in operating revenues and a
reduction in our subscriber acquisition costs and other operating costs and expenses. The increase in 2008 reflected principally both a significant increase in our operating revenues and a reduction in the commissions payable to our distributors.

Colombia and Panama

Operating revenues increased by 13.5% in 2009 and 10.2% in 2008. The increase in operating revenues in 2009 was attributable to the
appreciation of the Colombian peso against the Mexican peso and subscriber growth. The increase in operating revenues in 2008 was attributable principally to subscriber growth, increased traffic, the appreciation of the Colombian peso against the
Mexican peso and increased revenue from long distance charges. The Colombian peso appreciated 11.9% against the Mexican peso in 2008, and currency appreciation accounted for approximately 6.5% of the increase in revenues during 2008. Also, we began
providing long distance services in Colombia in 2008. These factors more than offset a decrease in interconnection tariffs of 50% in Colombia beginning in December 2007. In 2009, the number of subscribers in Colombia and Panama increased by 1.5% to
approximately 27.8 million as of December 31, 2009. In 2008, the number of subscribers in Colombia increased by 22.6%.

Average MOUs per subscriber increased by 10.2% in 2009 and 28.7% in 2008. ARPU increased by 8.8% in 2009 and decreased by 4.8% in 2008.
Calculated in nominal Colombian pesos, ARPU decreased by 3.3% in 2009 and 8.4% in 2008. The increase on average MOUs per subscriber in 2009 reflected primarily an increase in traffic resulting from the net increase in subscriber growth. The increase
on average MOUs per subscriber in 2008 reflected primarily the reduction in prices for our voice and data services. The decrease in ARPU in local currency during 2009 reflected the lower interconnection fees which were not compensated by the
increase in volume. The decrease in ARPU during 2008 reflected principally the lowering of our prices for voice and data services through promotions and lower rates. A substantial majority of our subscriber growth in 2009 and 2008

was attributable to an increase in prepaid customers, which generate on average less minutes of use and revenues than postpaid customers. Our churn rate increased from 2.4% in 2008 to 3.5% in
2009.

Our operating income increased by 8.2% in 2009 and 43.8% in 2008. Operating income in 2009 reflects the implementation
of stricter controls in our operating costs and expenses, particularly with respect to handset subsidies.Operating income in 2008 reflects a reduction in subscriber acquisition costs and the effect in 2007 of higher depreciation expense
resulting from the useful lives of certain GSM assets. Our operating margin was 32.0% in 2009 and 33.6% in 2008.

We began
operating in Panama in March 2009. The commencement of operations in Panama did not have a significant impact in the operating margin and results of operations of this segment.

Andean RegionEcuador and Peru

Operating revenues in Ecuador and Peru increased by 29.0% in 2009 and 24.7% in 2008. The increase in operating revenues in 2009 reflected
principally the appreciation of the local currencies against the Mexican peso and subscriber growth. Currency effects contributed to 71.7% of the growth in operating revenues in 2009. The increase in operating revenues in 2008 was attributable
principally to subscriber growth and increased traffic. In 2009, the number of subscribers increased by 14.7% to approximately 17.7 million at year-end 2009. In 2008, the number of subscribers increased by 24.9%.

Average MOUs per subscriber increased by 16.4% in 2009 and 27.3% in 2008. ARPU increased by approximately 13.0% in 2009 and decreased by
approximately 3.0% in 2008. The increase in ARPU during 2009 reflected the appreciation of local currencies against the Mexican peso. The decline in ARPU during 2008 reflected principally subscriber growth and a reduction in our rates per minute.
Our churn rate decreased from 2.4% in 2008 to 2.2% in 2009.

Operating income increased by 45.1% in 2009 and 41.8% in 2008.
Our operating margin was 29.4% in 2009 and 26.1% in 2008. The increase in operating margin during 2009 resulted from a reduction in subscriber acquisition costs. The increase in operating margin during 2008 resulted from an increase in revenues,
partially offset by a Ps. 136 million income-based payment related to our concession in Ecuador.

Central
AmericaEl Salvador, Guatemala, Honduras and Nicaragua

Operating revenues in El Salvador, Guatemala, Honduras and
Nicaragua increased by 13.0% in 2009 and decreased by 5.1% in 2008. The increase in 2009 reflected principally the 15.6% appreciation of the local currencies (mainly the dollar) against the Mexican peso, which compensated for a 2.6% decrease in
operating revenues in local currencies. The decrease in 2008 reflected principally a decrease in nearly all sources of operating revenue as a result of a decrease in our share of the market. In 2009, the number of wireless subscribers in Central
America increased by 4.1% to 9.5 million at year-end 2009. The number of fixed line subscribers increased by 0.8%, to approximately 2.3 million at year-end. In 2009, wireless services accounted for approximately 51.9% of our operating
revenues, and fixed-line and other services for approximately 48.1%, as compared to 52.5% and 47.5%, respectively, in 2008.

Average MOUs decreased by 6.9% in 2009 and 13.4% in 2008. ARPU increased by 5.1% in 2009 and decreased by 23.4% in 2008. The increase in
ARPU in 2009 reflects principally the appreciation of the local currencies, in particular the U.S. dollar, against the Mexican peso. Calculated in local currencies, ARPU decreased primarily as a result of increased competition for wireless customers
in the region.

Operating income decreased by 36.1% in 2009 and 35.5% in 2008. Operating margin was 10.7% in 2009 and 18.9% in
2008. The decrease in operating income and margin in 2009 reflected principally increased network maintenance costs and radio base station rental costs.The decrease in operating income and margin in 2008 reflected principally increased
network maintenance costs and acquisition costs related to triple-play.

United States

Operating revenues in the United States increased by 38.1% in 2009 and 6.0% in 2008. The increase in operating revenues in 2009 reflected
principally new commercial plans and promotional packages that contributed to the increase in subscriber growth. The increase in operating revenues in 2008 was attributable principally to subscriber growth and increased traffic. In 2009, the number
of TracFone subscribers increased by 28.9% to approximately 14.4 million as of December 31, 2009; and in 2008, the number of TracFone subscribers increased by 17.6% to approximately 11.2 million as of December 31, 2008.

Average MOUs per subscriber increased by 6.1% in 2009 and 5.6% in 2008. ARPU increased by 11.7% in 2009 and decreased by 9.0%
in 2008. The increase in ARPU in 2009 reflects our new commercial plans and promotional packages. The decline in ARPU in 2008 was primarily attributable to the increasing portion of TracFones traffic that is comprised of digital traffic, which
results in lower revenues per minute than analog traffic. The churn rate increased from 3.8% in 2008 to 4.0% in 2009.

Operating income increased by 1.4% in 2009 and decreased by 37.3% in 2008. TracFones operating margin decreased from 5.7% in 2008
to 4.2% in 2009. The increase in operating income in 2009 reflected currency effects due to the appreciation of the U.S. dollar against the Mexican peso and subscriber growth. The decrease in operating margin in 2009 reflects higher subscriber
acquisition costs due mainly to equipment subsidies and publicity expenses.

Dominican Republic

Operating revenues in the Dominican Republic increased by 26.8% in 2009 and 2.3% in 2008. The increase in 2009 reflects the appreciation
of the Dominican peso against the Mexican peso and subscriber growth. The increase in 2008 reflected principally subscriber growth in the wireless market and improved service promotions. In 2009, the number of wireless subscribers in the Dominican
Republic increased by 24.5%, and in 2008, the number of wireless subscribers increased by 44.6%. In 2009, the number of fixed line subscribers decreased by 0.9%, and the number of fixed line subscribers increased by 3.1% in 2008. In 2009, wireless
services accounted for approximately 49.2% of our operating revenues as compared to approximately 43.8% in 2008. Fixed-line and other services accounted for approximately 50.8% as compared to 56.2% in 2008.

Average MOUs decreased by 15.3% in 2009 and 6.7% in 2008. ARPU increased by 0.8% in 2009 and decreased by 15.5% in 2008. The decrease in
average MOUs and the increase in ARPU in 2009 reflect currency effects. Calculated in Dominican pesos, ARPU decreased by 12.7% in 2009. The declines in 2008 primarily reflected promotions and airtime subsidies and a growing proportion of prepaid
subscribers, who generate less revenue per line than postpaid subscribers.

Operating income increased by 15.4% in 2009 and
decreased by 14.5% in 2008. Operating margin was 27.3% in 2009 and 30.0% in 2008. The increase in operating income and the decrease in operating margin in 2009 reflected principally indirect taxes on network maintenance and operation costs.The decrease in operating income and margin in 2008 reflected principally the growing proportion of our prepaid subscribers, which resulted in increased subscriber acquisition costs, equipment subsidies and customer service expenses.

CaribbeanPuerto Rico and Jamaica

Operating revenues in the Caribbean increased by 14.7% in 2009 and 31.7% in 2008. The increase in 2009 and 2008 reflected principally the
appreciation of the U.S. dollar against the Mexican peso and organic growth. In 2009, the number of wireless subscribers in Puerto Rico and Jamaica increased by 37.6%, and in 2008, the number of wireless subscribers increased by 14.5%. In 2009, the

decrease in operating income and operating margin in 2009 reflected principally an increase in indirect taxes including two real property taxes that became effective in Puerto Rico in 2009.

Liquidity and Capital Resources

Principal Uses of Cash

We generate substantial resources from our operations. On a consolidated basis, operating activities provided Ps. 152,809 million in
2009 and Ps. 87,464 million in 2008. Our cash and cash equivalents amounted to Ps. 27,446 million at December 31, 2009, compared to Ps. 22,092 million as of December 31, 2008. We believe that our working capital is
sufficient for our present requirements. We use the cash that we generate from our operations primarily for the following purposes:



| |  |  | We must make substantial capital expenditures to continue expanding and improving our networks in each country in which we operate. In 2009 and 2008,
we invested approximately Ps. 45,395 million and Ps. 57,134 million, respectively, in plant, property and equipment. As of December 31, 2009, we had not disbursed Ps. 24,621 million of our investments in 2008, which will be
disbursed in 2010. We have budgeted capital expenditures for 2010 to be approximately U.S.$ 3,500 billion (Ps. 45,815 million). See Capital Expenditures under Item 4.

| |  |  | During 2008 we spent approximately Ps. 13,737 million to acquire or renew licenses, principally Ps. 8,830 million to acquire additional
spectrum in Brazil, Ps. 3,001 million to renew our concession in Ecuador and Ps. 896 million to acquire a license in Panama. We did not spend any funds in the acquisition or renewal of licenses in 2009. The amount we spend on acquisitions
and licenses varies significantly from year to year, depending on acquisition opportunities, concession renewal schedules and needs for more spectrum.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | In 2008, we had a significant increase in our inventory, as compared to 2007, resulting from an increase in volume and inventory acquisition costs and
currency effects.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We must pay interest on our indebtedness and repay principal when due. As of December 31, 2009, we had Ps. 9,168 million of principal due in
2010.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | If we have resources after meeting our obligations and capital expenditure requirements, we may pay dividends, or repurchase our own shares from time
to time. We paid Ps. 25,979 million in dividends in 2009 and Ps. 8,904 million in dividends in 2008, and our shareholders have approved the payment of a Ps. 0.32 dividend per share in 2010. Dividends for 2009 included an extraordinary
dividend of Ps. 0.50 per share paid on December 2009. We also spent (including commissions and value-added taxes) Ps. 24,706 million repurchasing our own shares in the open market in 2009 and Ps. 41,755 million in 2008. Our
shareholders have authorized additional repurchases, and whether we do so will depend on considerations including market price and our other capital requirements. We have made additional repurchases in 2010.

##### Table of Contents

The following table summarizes certain contractual liabilities as of December 31, 2009.
Our purchase obligations and approximately 51.4% of our debt described below are denominated in U.S. dollars. The table does not include accounts payable or pension liabilities, and amounts set forth in the table do not include interest and do not
give effect to hedging transactions.

|(2) | See discussion below.
|--- | ---------------------

Other
than the amounts described in the table above, we had no other outstanding material purchase commitments as of December 31, 2009. We enter into a number of supply, advertising and other contracts in the ordinary course of business, but we do
not believe that any of those contracts are material to our liquidity.

Under many of our concessions and licenses, we are
required to make annual royalty payments in order to continue using such concessions and licenses. These payments are typically calculated as a percentage of gross revenues generated under such concessions and licenses. In the case of the 1900
megahertz spectrum (Band F) concessions in Mexico, however, we are required to pay Ps. 255 million (subject to adjustment for inflation) annually for 20 years in respect of the 10 megahertz acquired during 2005.

We could have opportunities in the future to invest in other telecommunications companies worldwide, primarily in Latin America and the
Caribbean, because we believe the telecommunications sector in Latin America will continue to undergo consolidation. For example, we may pursue further market consolidation opportunities in Brazil and Argentina depending on their terms and
conditions. We can give no assurance as to the extent, timing or cost of such investments. We may also pursue opportunities in other areas in the world.Some of the assets that we acquire may require significant funding for capital
expenditures. See the discussion included earlier in this annual report under OverviewEffects of Recent Acquisitions under this Item 5 for more information about these transactions.

Borrowings

In addition to funds generated from operations, we have used borrowings to fund acquisitions and capital expenditures and refinance debt.
We have relied on a combination of equipment financings, borrowings from international banks and borrowings in the Mexican and international capital markets. Beginning in the second half of 2008, with the difficult circumstances in the credit
markets, we arranged several equipment financing facilities to further improve our liquidity position. As of the date of this report, we have an aggregate of U.S.$1,297 million in committed undrawn equipment financing facilities from three different
sources.

As of December 31, 2009, our total consolidated indebtedness was Ps. 110,909 million, compared to Ps.
143,486 million as of December 31, 2008. Our net debt (total debt minus cash and cash equivalents) at December 31, 2009 decreased by 31.2% as compared to December 31, 2008. This decrease reflects, among other things, our
increased capacity for generating cash flow.

##### Table of Contents

During 2010, we have taken advantage of favorable market conditions to raise a substantial
amount of additional funds by issuing debt securities in different markets. In March 2010, we issued three series of peso-denominated notes in the domestic Mexican market, consisting of Ps. 4,600 million in notes maturing in 2015, Ps. 7,000 million
in notes maturing in 2020 and Ps. 3,271 million in notes maturing in 2025. Later in March 2010, we issued three series of U.S. dollar-denominated notes in the international market, consisting of U.S.$750 million in notes due 2015, U.S.$2.0 billion
in notes due 2010 and U.S.$1.25 billion in notes due 2040. In April 2010, we issued Swiss franc-denominated notes in the domestic Swiss market, consisting of CHF230 million in notes due 2015.

Without taking into account the effects of derivative financial instruments that we use to manage our interest rate and currency risk
liabilities, approximately 76.2% of our indebtedness at December 31, 2009 was denominated in currencies other than Mexican pesos (approximately 51.4% in U.S. dollars and 24.8% in other currencies, principally in Colombian and Chilean pesos and
euros), and approximately 24.5% of our consolidated debt obligations bore interest at floating rates. Of our total debt at December 31, 2009, Ps. 6,355 million (or 5.7%) was classified as short-term based on the original terms.

Our ability to access the international debt capital markets on the terms described below has been helped by the credit rating given to
our debt. As of the date of this annual report, our dollar-denominated senior notes are rated A2 by Moodys Investors Service, BBB+ (positive watch) by Standard and Poors Rating Group and A- by Fitch Ratings. Adverse economic conditions
or changing circumstances may, however, cause our ratings to be downgraded. The weighted average cost of all our third-party debt at December 31, 2009 (excluding commissions and reimbursement of certain lenders for Mexican taxes withheld) was
approximately 5.8%.

Our major categories of indebtedness at December 31, 2009 are as follows:



| |  |  | U.S. dollar-denominated senior notes.    At December 31, 2009, we had approximately U.S.$3.9 billion (Ps. 51,608
million) outstanding under series of U.S. dollar-denominated senior notes issued in the international capital markets between 2004 and 2009:
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | U.S.$795 million (Ps. 10,381 million) senior notes due 2014, bearing interest at a fixed rate of 5.500%;
| | - |  | --------------------------------------------------------------------------------------------------------



| |  |  | U.S.$473 million (Ps. 6,181 million) senior notes due 2015, bearing interest at a fixed rate of 5.750%;
| | - |  | -------------------------------------------------------------------------------------------------------



| |  |  | U.S.$583 million (Ps. 7,615 million) senior notes due 2017, bearing interest at a fixed rate of 5.625%;
| | - |  | -------------------------------------------------------------------------------------------------------



| |  |  | U.S.$750 million (Ps. 9,794 million) senior notes due 2019, bearing interest a fixed rate of 5.000%;
| | - |  | ----------------------------------------------------------------------------------------------------



| |  |  | U.S.$981 million (Ps. 12,815 million) senior notes due 2035, bearing interest at a fixed rate of 6.375%; and
| | - |  | ------------------------------------------------------------------------------------------------------------



| |  |  | U.S.$369 million (Ps. 4,822 million) senior notes due 2037, bearing interest at a fixed rate of 6.125%.
| | - |  | -------------------------------------------------------------------------------------------------------



| |  |  | Mexican-peso denominated senior notes.    At December 31, 2009, we had approximately Ps. 12,872 million
outstanding under two series of peso-denominated senior notes sold in the international and Mexican capital markets: on October 5, 2005, we issued Ps. 5,000 million in principal amount of 9.0% senior notes due January 2016 and on
December 18, 2006 we issued Ps. 8,000 million in principal amount of 8.46% senior notes due 2036. These notes are denominated in Mexican pesos, but all amounts in respect of the notes are payable in U.S. dollars, unless a holder of notes
elects to receive payment in Mexican pesos in accordance with certain specified procedures.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Mexican peso-denominated domestic senior notes (certificados bursátiles).    At December 31, 2009, we had
Ps. 13,491 million in domestic senior notes that were sold in the Mexican capital markets.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

| | These domestic senior notes were issued by us between 2002 and 2009, and have varying maturities, ranging from 2010 through 2018. Some bear interest at fixed rates, and others at variable rates
based on CETES (a rate based on the cost of Mexican treasuries) or TIIE (a Mexican interbank rate). Recent issuances of domestic senior notes include:
| | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | On April 11, 2007, we issued Ps. 500 million in 5-year floating domestic senior notes. The notes bear interest at a discount of 6 basis
points below TIIE, and mature on April 5, 2012;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | On November 1, 2007, we issued Ps. 2,500 million in 3-year floating domestic senior notes. The notes bear interest at a discount of 10 basis
points below TIIE, and mature on October 28, 2010;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | On November 1, 2007, we issued Ps. 2,000 million in 10-year fixed rate domestic senior notes. The notes bear interest at a rate of
8.39% per annum, and mature on October 19, 2017;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | On March 7, 2008, we issued Ps. 2,500 million in 10-year fixed rate domestic senior notes. The notes bear interest at a rate of
8.11% per annum, and mature on February 22, 2018;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | On September 12, 2008, we issued Ps. 3,000 million in 5-year floating domestic senior notes. The notes bear interest at a spread of 55 basis
points over CETES, and mature on September 6, 2013; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | On September 12, 2008, we issued Ps. 2,100 million in 5-year UDI denominated equivalent fixed rate domestic senior notes. The notes bear
interest at a rate of 4.10% per annum and mature on September 6, 2013.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Bank loans.    At December 31, 2009, we had approximately Ps. 9,226 million outstanding under a number of bank
facilities bearing interest principally at fixed and variable rates based on LIBOR. We are also party to a U.S.$2 billion revolving syndicated facility that matures on April 2011. At December 31, 2009, the entire U.S.$2 billion was available
for borrowing. Loans under the facility bear interest at LIBOR plus a spread. The syndicated facility limits our ability to incur secured debt, to effect a merger as a result of which the surviving entity would not be América Móvil or
Telcel, to sell substantially all of our assets or to sell control of Telcel. The facility does not allow us to impose any restrictions on the ability of Telcel to pay dividends or make distributions to us. In addition, the bank facilities require
us to maintain a consolidated ratio of debt to EBITDA not greater than 4.0 to 1.0 and a consolidated ratio of EBITDA to interest expense not less than 2.5 to 1.0.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Equipment financing facilities with support from export development agencies.    We have a number of equipment financing
facilities, under which export development agencies provide support for financing to purchase exports from their respective countries. These facilities are medium- to long-term, with periodic amortization and interest at a spread over LIBOR/EURIBOR.
They are extended to us or to operating subsidiaries, with the guarantee of Telcel. The aggregate amount outstanding under equipment financing facilities at December 31, 2009 was U.S.$928 million (Ps. 12,124 million).
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Sale and leasebacks.    Our subsidiaries in Ecuador, Peru, Nicaragua and Honduras have entered into sale and leaseback
transactions with respect to a portion of its telephone plant. At December 31, 2009, lease payment obligations under these contracts amounted to U.S.$87 million (Ps. 1,133 million). Payments are due on a monthly and three-month basis
through 2012 and bear interest at fixed or variable rates plus a spread.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Colombian peso-denominated notes.    In 2004, Comcel issued Colombian peso-denominated notes that were sold in the Colombian
capital markets in three different series. These notes bear interest at a variable rate based on the Colombian consumer price index rate (IPC) plus a spread, and mature in 2010 and 2013. These notes are guaranteed by América Móvil. In
2006, Comcel issued Colombian peso-denominated notes that were sold in the Colombian capital markets. These notes bear interest at a 7.59% fixed rate, and mature on 2016. These notes are not guaranteed by América Móvil. At
December 31, 2009, the aggregate principal amount outstanding under these notes was Ps. 5,749 million.

##### Table of Contents

All of the public securities issued by América Móvil in international and
Mexican capital markets and amounts due under our syndicated loan facility and export credit facilities are guaranteed by Telcel.

At December 31, 2009, Telcel had, on an unconsolidated basis, unsecured and unsubordinated obligations of approximately Ps.
93,908 million (U.S.$7,204 million), excluding debt owed to us or our other subsidiaries. This amount represents outstanding obligations of Telcel under guarantees of parent company and subsidiary indebtedness. In addition, at December 31,
2009, our operating subsidiaries other than Telcel had indebtedness of Ps. 17,001 million (U.S.$1,302 million).

Risk Management

We regularly assess our interest rate and currency exchange exposures in order to determine how to manage the risk associated
with these exposures. In Mexico, we have indebtedness denominated in currencies, principally the U.S. dollar, other than the currency of the operating environment. We use derivative financial instruments to adjust the resulting exchange rate
exposures. We do not use derivatives to hedge the exchange rate exposures that arise from having operations in different countries. We also use derivative financial instruments from time to time to adjust our exposure to variable interest rates or
to reduce our costs of financing. Our practices vary from time to time depending on our judgment of the level of risk, expectations as to exchange or interest rate movements and the costs of using derivative financial instruments. We may stop using
derivative financial instruments or modify our practices at any time. As of December 31, 2009, after taking into account derivative transactions, approximately 30.5% of our total debt was denominated in U.S. dollars and approximately 28.5% was
subject to floating rates.

As of December 31, 2009, we had the following derivatives positions, with an aggregate fair
value of Ps. 8,361 million:



| |  |  | U.S. dollar-Mexican peso cross currency swaps with a notional amount of U.S.$147 million with respect to our total U.S. dollar-denominated debt. Under
these swaps, we have replaced our obligation to make payment in U.S. dollars with an obligation to make payment in Mexican pesos;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | U.S. dollar-Mexican peso forwards for a total notional amount of U.S.$1,965 million to hedge our exposure to our U.S. dollar denominated debt;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Euro-Mexican peso cross currency swap with a notional amount of EUR 82 million with respect to our total Euro-denominated debt. Under this
swap we replaced our obligation to make payment in Euros with an obligation to make payment in Mexican pesos;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Euro-U.S. dollar cross currency swaps with a notional amount of EUR 143 million with respect to our total Euro-denominated debt. Under this
swap we replaced our obligation to make payment in Euros with an obligation to make payment in U.S. dollars; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | A Japanese Yen-U.S. dollar denominated cross-currency swap with a notional amount of Yen¥13,000 million with respect to our total Japanese-Yen
denominated debt. Under this swap, we replaced our obligation to make payment in Japanese Yen with an obligation to make payment in U.S. dollars.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Off-Balance Sheet Arrangements

As of December 31, 2009, we had no off-balance sheet arrangements that require disclosure under applicable SEC regulations.

U.S. GAAP Reconciliation

We had net income under U.S. GAAP of Ps. 74,360 million in 2009 Ps. 54,252 million in 2008 and Ps. 55,529 million in 2007.
Compared to Mexican FRS, net income under U.S. GAAP was approximately 3.4% lower in 2009, 8.9% lower in 2008 and 5.4% lower in 2007.

##### Table of Contents

There are several differences between Mexican FRS and U.S. GAAP that affect our net income
and equity. The most significant difference in their effect on 2009 net income related to the depreciation resulting from the restatement of the carrying value of property, plant and equipment to reflect the effects of inflation up to
December 31, 2007. Under Mexican FRS through December 31, 2007, in order to reflect the effects of inflation on our imported telephone plant and equipment, we restated its value based on the rate of inflation in the respective country of
origin and the prevailing exchange rate at the balance sheet date. The use of this method, which is known as the specific indexation method, is not permitted under U.S. GAAP, and as a result, for purposes of U.S. GAAP, we restated non-monetary
assets based on the Mexican National Consumer Price Index as of December 31, 2007. For a discussion of the principal differences between Mexican FRS and U.S. GAAP, see Note 21 to our audited consolidated financial statements.

Use of Estimates in Certain Accounting Policies

In preparing our financial statements, we make estimates concerning a variety of matters. Some of these matters are highly uncertain, and
our estimates involve judgments we make based on the information available to us. In the discussion below, we have identified several of these matters for which our financial presentation would be materially affected if either (1) we used
different estimates that we could reasonably have used or (2) in the future we change our estimates in response to changes that are reasonably likely to occur.

The discussion addresses only those estimates that we consider most important based on the degree of uncertainty and the likelihood of a
material impact if we used a different estimate. There are many other areas in which we use estimates about uncertain matters, but the reasonably likely effect of changed or different estimates is not material to our financial presentation.

Purchase accountingpurchase price allocation

During 2008 and 2007, we made a number of business acquisitions applying the purchase method of accounting. Accounting for the acquisition
of a business under the purchase method requires the allocation of the purchase price to the various assets and liabilities of the acquired business. For most assets and liabilities, purchase price allocation is accomplished by recording the asset
or liability at its estimated fair value. The most difficult estimations of individual fair values are those involving properties, plant and equipment and identifiable intangible assets, such as our licenses and trademarks. We use all available
information to make these fair value determinations, including the retention of appraisers to determine the fair value of property and equipment, trademarks and an examination of the market value of licenses with similar characteristics to determine
the fair value of licenses.

Estimated useful lives of plant, property and equipment

We estimate the useful lives of particular classes of plant, property and equipment in order to determine the amount of depreciation
expense to be recorded in each period. Depreciation expense is a significant element of our costs and expenses, amounting in 2009 to Ps. 42,953 million, or 10.9% of our operating costs and expenses. See Note 7 to our audited consolidated
financial statements.

We currently depreciate most of our telephone plant and equipment based on an estimated useful life
determined upon the expected particular conditions of operations and maintenance in each of the countries in which we operate. The estimates are based on our historical experience with similar assets, anticipated technological changes and other
factors, taking into account the practices of other telecommunications companies. We review estimated useful lives each year to determine whether they should be changed, and at times, we have changed them for particular classes of assets. We may
shorten the estimated useful life of an asset class in response to technological changes, changes in the market or other developments. This results in increased depreciation expense. For example, during 2007, we shortened the useful life of TDMA and
GSM equipment, particularly in Colombia and Brazil, to reflect the expected migration of customers to newer technologies. This

##### Table of Contents

change resulted in an increase in our depreciation expense for 2007 of Ps. 5,796 million. In 2009, we recorded a depreciation expense of Ps. 4,462 million resulting from the shortening of
the useful lives of certain GSM assets in Brazil. See Note 7 to our audited consolidated financial statements.

Impairment of Long-Lived Assets, Intangibles and Goodwill

We have large amounts of long-lived assets on our balance sheet. Under Mexican FRS and U.S. GAAP, we are required to test long-lived
assets for impairment whenever events or circumstances indicate that the carrying amount may not be recoverable for plant, property and equipment and licenses and trademarks. Impairment testing for goodwill is required to be performed on an annual
basis. To estimate the fair value of long-lived assets, we typically make various assumptions about the future prospects for the business to which the asset relates, consider market factors specific to that business and estimate future cash flows to
be generated by that business. Based on these assumptions and estimates as well as guidance provided by Mexican FRS and U.S. GAAP relating to the impairment of long-lived assets, we determine whether we need to take an impairment charge to reduce
the net carrying value of the asset as stated on our balance sheet to reflect its estimated fair value. Assumptions and estimates about future values and remaining useful lives are complex and often subjective. They can be affected by a variety of
factors, including external factors, such as industry and economic trends, and internal factors, such as changes in our business strategy and our internal forecasts. Different assumptions and estimates could materially impact our reported financial
results. More conservative assumptions of the anticipated future benefits from these businesses could result in impairment charges, which would decrease net income and result in lower asset values on our balance sheet. Conversely, less conservative
assumptions could result in smaller or no impairment charges, higher net income and higher asset values.

In 2008, we
recognized an impairment in the value of goodwill of Ps. 527 million, an impairment in the value of our plants, property and equipment of Ps. 113 million and an impairment in the value of our licenses of Ps. 99 million. During 2009,
we did not recognize any impairment of long-lived assets or goodwill.

Deferred Taxes

We are required to estimate our income taxes in each of the jurisdictions in which we operate. This process involves the
jurisdiction-by-jurisdiction estimation of actual current tax exposure and the assessment of temporary differences resulting from the differing treatment of certain items, such as accruals and amortization, for tax and financial reporting purposes,
as well as net operating loss carry forwards and other tax credits. These items result in deferred tax assets and liabilities, which are included in our consolidated balance sheets. We must assess in the course of our tax planning procedures the
fiscal year of the reversal of our deferred tax assets and liabilities, and if there will be future taxable profits in those periods to support the recognition of the deferred tax assets. Significant management judgment is required in determining
our provisions for income taxes, deferred tax assets and liabilities. The analysis is based on estimates of taxable income in the jurisdictions in which the group operates and the period over which the deferred tax assets and liabilities will be
recoverable or settled. If actual results differ from these estimates, or we adjust these estimates in future periods, our financial position and results of operations may be materially affected.

We record a valuation allowance to reduce the deferred tax assets to an amount that we believe is more likely than not to be realized. In
assessing the need for the valuation allowance, we considered future taxable income and ongoing tax planning strategies. In the event that our estimates of projected future taxable income and benefits from tax planning strategies are lowered, or
changes in current tax regulations are enacted that would impose restrictions on the timing or extent of our ability to utilize the tax benefits of net operating loss carry-forwards in the future, an adjustment to the recorded amount of net deferred
tax assets would be made, with a related charge to income.

Accruals

Accruals are recorded when, at the end of the period, we have a present obligation as a result of past events, whose settlement requires
an outflow of resources that is considered probable and can be measured reliably. This obligation may be legal or constructive, arising from, but not limited to, regulation, contracts, common practice or public commitments, which have created a
valid expectation for third parties that we will assume certain responsibilities. The amount recorded is the best estimation performed by our management in respect of the expenditure that will be required to settle the obligations, considering all
the information available at the date of our financial statements, including the opinion of external experts, such as legal advisors or consultants. Accruals are adjusted to account for changes in circumstances for ongoing matters and the
establishment of additional accruals for new matters.

If we are unable to reliably measure the obligation, no accrual is
recorded and information is then presented in the notes to our consolidated financial statements.

Because of the inherent
uncertainties in this estimation, actual expenditures may be different from the originally estimated amount recognized.

Labor Obligations

We recognize liabilities on our balance sheet and expenses in our income statement to reflect our obligations related to our
post-retirement seniority premiums, pension and retirement plans in the countries in which we operate and offer defined contribution and benefit pension plans. The amounts we recognize are determined on an actuarial basis that involves many
estimates and accounts for post-retirement and termination benefits in accordance with Mexican FRS and U.S. GAAP.

We use
estimates in four specific areas that have a significant effect on these amounts: (a) the rate of return we assume our pension plan will achieve on its investments, (b) the rate of increase in salaries that we assume we will observe in
future years, (c) the discount rates that we use to calculate the present value of our future obligations and (d) the expected rate of inflation. The assumptions we have applied are identified in Note 11 (Mexican FRS) and Note 21
(U.S. GAAP) to our audited consolidated financial statements. These estimates are determined based on actuarial studies performed by independent experts using the projected unit-credit method. The latest actuarial computation was prepared as of
December 2009. We review the estimates each year, and if we change them, our reported expense for pension costs may increase or decrease according to market conditions.

Allowance for Doubtful Accounts

We maintain an allowance for doubtful accounts for estimated losses resulting from the failure of our customers, distributors and cellular
operators to make required payments. We base these estimates on the individual conditions of each of the markets in which we operate that may impact the collectibility of accounts. In particular, in making these estimates we take into account
(i) with respect to accounts with customers, the number of days since the calls where made, (ii) with respect to accounts with distributors, the number of days invoices are overdue and (iii) with respect to accounts with cellular
operators, both the number of days since the calls where made and any disputes with respect to such calls. The amount of loss, if any, that we actually experience with respect to these accounts may differ from the amount of the allowance maintained
in connection with them.

MANAGEMENT

Directors

Our Board of
Directors has broad authority to manage our company. The Board of Directors is supported by our committees, especially by our Audit and Corporate Practices Committee, which is comprised by independent members. In particular, the Board of Directors
must approve prior opinions of the competent committee, among others:



| |  |  | our non-ordinary course transactions with related parties;
| | - |  | ----------------------------------------------------------



| |  |  | the use and disposition of the companys assets;
| | - |  | ------------------------------------------------



| |  |  | certain material transactions such as (a) transactions not in the ordinary course of business, (b) transactions representing an investment
greater than 5% of the companys assets on a consolidated basis and (c) transactions involving guarantees or the incurrence of financial obligations for more than 5% of the companys assets on a consolidated basis;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | executive and director compensation;
| | - |  | ------------------------------------



| |  |  | appoint and discharge our chief executive officer; and
| | - |  | ------------------------------------------------------



| |  |  | waivers for board members, executives and other persons with influence on the company, to benefit from business opportunities pertaining to the
company.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------

The company must publicly disclose any case in which the resolution of the board differs from the
opinion of the committee regarding any of these matters.

Additionally, in the event that a person or group of persons intend
to acquire an amount of shares equal or exceeding 10% of our voting stock, our Board of Directors authorization is required. In the event that our Board of Directors rejects the relevant authorization, it shall appoint a substitute acquirer.

Our bylaws provide for the Board of Directors to consist of between five and twenty one directors and allow for the
appointment of an equal number of alternate directors. Directors need not be shareholders. A majority of our directors and a majority of the alternate directors must be Mexican citizens and elected by Mexican shareholders. A majority of the holders
of the AA Shares and A Shares voting together elect a majority of the directors and alternate directors, provided that any holder or group of holders of at least 10% of the total AA Shares and A Shares is entitled to name one director and an
alternate director. Two directors and two alternate directors, if any, are elected by a majority vote of the holders of L Shares. Each alternate director may attend meetings of the Board of Directors and vote in the absence of a corresponding
director. Directors and alternate directors are elected or ratified at each annual general meeting of shareholders and each annual ordinary special meeting of holders of L Shares, and each serves until a successor is elected and takes office. In
accordance with the Mexican Securities Market Law (Ley del Mercado de Valores, or the Mexican Securities Market Law), shareholders are required to make a determination as to the independence of our directors, though the CNBV may
challenge this determination. Pursuant to our bylaws and the Mexican Securities Market Law, at least 25% of our directors must be independent. In order to have a quorum for a meeting of the Board of Directors, a majority of those present must be
Mexican nationals.

All of the current members of the Board of Directors, the Executive Committee, the Audit and Corporate
Practices Committee, and the Operations in Puerto Rico and the United States of America Committee, as well as the Corporate Secretary and the Corporate Pro-Secretary, were elected or ratified at the annual general shareholders meeting held on
April 7, 2010, with eight directors elected by the AA Shares and A Shares voting together and two directors elected by the L Shares. No alternate directors were appointed.

Our bylaws provide that the members of the Board of Directors are appointed for terms of one
year. Pursuant to Mexican law, members of the Board continue in their positions after the expiration of their terms for up to an additional 30 day period if new members are not appointed. Furthermore, in certain circumstances provided under the
Mexican Securities Law, the Board of Directors may appoint temporary directors who then may be ratified or substituted by the shareholders meetings. The names and positions of the members of the Board elected and ratified at the annual general
shareholders meeting held on April 7, 2010, their year of birth, and information concerning their committee membership and principal business activities outside América Móvil are as follows:

Executive Committee

Our bylaws provide that the Executive Committee may generally exercise the powers of the Board of Directors, with certain exceptions. In
addition, the Board of Directors is required to consult the Executive Committee before deciding on certain matters set forth in the bylaws, and the Executive Committee must provide its views within ten calendar days following a request from the
Board of Directors, the Chief Executive Officer or the Chairman of the Board of Directors. If the Executive Committee is unable to make a recommendation within ten calendar days or if a majority of the Board of Directors or any other corporate body
duly acting within its mandate determines in good faith that action cannot be deferred until the Executive Committee makes a recommendation, the Board of Directors is authorized to act without such recommendation. The Executive Committee may not
delegate its powers to special delegates or attorneys-in-fact.

The Executive Committee is elected from among the directors
and alternate directors by a majority vote of the holders of common shares (AA Shares and A Shares). The Executive Committee is currently comprised of three members. The majority of its members must be Mexican citizens and elected by Mexican
shareholders. Two members of the Executive Committee are named by our Mexican controlling shareholders and one member by AT&T, Inc. (formerly SBC International, Inc.). See Major Shareholders under Item 7. The current members of
the Executive Committee are Messrs. Patrick Slim Domit and Daniel Hajj Aboumrad, named by the Mexican controlling shareholders, and Mr. Rayford Wilkins, named by AT&T.

The Audit and Corporate Practices Committee consists of Messrs. Alejandro Soberón Kuri, Chairman, Ernesto Vega Velasco, Pablo

approximately 87.1% of the employees of Telcel. All management positions at Telcel are held by non-union employees. Salaries and certain benefits are renegotiated every year. In March 2010, Telcel and the union agreed to a 4.8% nominal increase in
basic wages.

Under our labor agreements and Mexican labor law, we are obligated to pay seniority premiums to retiring
employees and pension and death benefits to retired employees. Retirees will be entitled to receive pension increases whenever salary increases are granted to current employees.

Some of our foreign subsidiaries, including our Brazilian subsidiaries, Telgua, ENITEL, CTE, Claro Chile, AMX Argentina and TELPRI, also
have active employee unions.

We believe that we have good current relations with our workforce.

|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

According to reports of
beneficial ownership of our shares filed with the SEC on March 1, 2010, Carlos Slim Helú, together with his sons and daughters (together, the Slim Family), may be deemed to control us through their beneficial ownership held
by a trust and another entity and their direct ownership of shares.

Our former controlling shareholder, Amtel, and AT&T
Inc., as successors of Carso Global Telecom and SBC International, Inc., respectively, were parties to an agreement relating to their ownership of AA Shares. Among other things, the agreement subjects certain transfers of AA Shares by either party
to a right of first offer in favor of the other party, although the right of first offer does not apply to the conversion of AA Shares to L Shares, as permitted by our bylaws, or the subsequent transfer of L Shares. The agreement also provides for
the composition of the Board of Directors and the Executive Committee and for each party to enter into a Management Services Agreement with us. According to reports of beneficial ownership of our shares filed with the SEC on May 4, 2007 the
Slim Family and a Mexican trust that holds AA Shares for the benefit of the Slim Family (the Control Trust) expect to enter into amendments of the agreement with AT&T pursuant to which the Slim Family and the Control Trust will act
as successor to Amtel (except that we do not expect to enter into a Management Services Agreement with the Control Trust or the Slim Family).According to reports of beneficial ownership filed with the SEC, the Slim Family may be deemed to
control us through their beneficial ownership of shares held by the Control Trust and Inmobiliaria Carso and their direct ownership of shares. See Directors and Executive Committee under Item 6 and Related Party
Transactions under this item 7.

The following table identifies each owner of more than 5% of any series of our shares
as of April 30, 2010. Except as described in the table below and the accompanying notes, we are not aware of any holder of more than 5% of any series of our shares. Figures below do not include the total number of L Shares that would be held by
each shareholder upon conversion of the maximum number of AA Shares or A Shares, as provided for under our bylaws. See BylawsShare Capital under Item 10. Holders of five percent or more of any class of our shares have the same
voting rights with respect to their shares as do holders of less than five percent of the same class.

RELATED PARTY TRANSACTIONS

Transactions with Telmex, Telmex Internacional and subsidiaries

We have, and expect to continue to have, a variety of contractual relationships with Telmex, Telmex Internacional and their subsidiaries,
including some of their international subsidiaries.

According to beneficial ownership reports filed with the SEC, Telmex and
Telmex Internacional may be deemed to be under common control with us.

Continuing Commercial Relationships

Because both we, on the one hand, and Telmex or Telmex Internacional, on the other hard, provide telecommunications services in some of
the same geographical markets, we have extensive operational relationships. These relationships include interconnection between their respective networks; use of facilities, particularly for the co-location of equipment on premises owned by Telmex;
use of their private circuits; the provision of long distance services to our customers; and use by each of the services provided by the other. These relationships are subject to a variety of different agreements, and the most significant of these
relationships are between Telcel and Telmex in Mexico and between our Brazilian subsidiaries and Embratel, a subsidiary of Telmex Internacional that provides fixed-line telecommunication services, in Brazil. Many of them are also subject to specific
regulations governing telecommunications services. The terms of these agreements are generally similar to those on which each company does business with unaffiliated parties.

These operational relationships are material to our financial performance. In 2009, Ps. 18,070 million of our total operating
revenues were attributable to interconnection with Telmex and its subsidiaries, primarily representing payments under the calling party pays system arising from fixed-to-mobile calls. We had Ps. 274,481 million in accounts receivable from
Telmex and certain of its subsidiaries. We had Ps. 25,628 million in accounts receivable from Telmex Internacional and certain of its subsidiaries, and accounts payable of Ps. 615,804 million to Telmex Internacional and certain of its
subsidiaries at December 31, 2009. Also in 2009, Ps. 7,218 million of our cost of services was attributable to payments to Telmex and its subsidiaries, primarily representing interconnection payments for long-distance calls carried by
Telmex or its subsidiaries and use of facilities under leases and collocation agreements with Telmex or its subsidiaries.

In
the ordinary course of business, our subsidiaries in Brazil lease real property from Embratel. The aggregate amount of consideration paid for these leases is approximately R$1.2 million (Ps. 9.0 million) on an annual basis. We may, from
time to time, lease additional real estate from Embratel.

Telmex distributes Telcel handsets and prepaid cards on commercial
terms, and Embratel provides call center services to the operating subsidiaries of Claro Participações S.A.

Other Commercial Relationships

In 2005, Telmex Argentina, S.A., a subsidiary of Telmex Internacional, and AMX Argentina, S.A. entered into an agreement for the
construction of approximately 1,943 kilometers of fiber optic transmission lines in Argentina. The project concluded in 2009, representing a total cost of approximately Ps. 313 million (U.S. $24 million, based on the exchange rate on
December 31, 2009).

In 2005, our subsidiary, Claro Chile, S.A. and Telmex Chile Holding, S.A. (Telmex
Chile), a subsidiary of Telmex Internacional, entered into an agreement for the provision of capacity and infrastructure by Telmex Chile for a period of 20 years. Pursuant to the agreement, Claro Chile pays a monthly disbursement of U.S.$22.0
million (Ps. 190.0 million, based on the exchange rate on December 31, 2009). The amount recorded in the results of operations as of December 31, 2009 for this agreement was U.S.$265 million. (Ps. 3,460 million, based on the exchange
rate on December 31, 2009).

In November 2005, Embratel entered into an agreement with Claro Participações
to provide backbone network capacity to our operating subsidiaries in Brazil for a period of 20 years. Pursuant to this agreement our subsidiaries in Brazil are required to pay Embratel a monthly fee that ranges between R$4.0 million and R$6.0
million (Ps. 24.5 million and Ps. 36.8 million, based on the exchange rate on December 31, 2009), depending on the capacity provided under the agreement.

In 2006, Telmex Perú S.A., a subsidiary of Telmex Internacional, and América Móvil Perú, S.A.C., entered into
a turnkey fiber optic network construction agreement in order to jointly build a fiber optic network along the coast of Peru of 2,823 kilometers for approximately Ps. 561 million (U.S.$43 million, based on the exchange rate on December 31,
2009). The construction was awarded through a private bidding process to our affiliates Carso Infraestructura y Construcción, S.A. de C.V. (CICSA) and Grupo Condumex, S.A. de C.V. The project concluded in November 2009.

In 2009, AMX Argentina began the construction of approximately 3,100 kilometers of fiber optic transmission lines in southern
Argentina. The construction work and cable are valued at Ps. 503 million (U.S.$39.0 million, based on the exchange rate on December 31, 2009). Once the work is finalized, we expect that AMX Argentina will enter into a 30-year license for
use agreement with Telmex Argentina, a subsidiary of Telmex Internacional. Additionally, Telmex Internacional transferred to us the rights to use for 15 years the fiber optic ring serving the Buenos Aires metropolitan area (commonly known in
Argentina as the AMBA), which covers most of the urban links of the greater Buenos Aires area (commonly known in Argentina as Gran Buenos Aires) with an approximate value of Ps. 8.1 million (US$ 0.6 million, based on the exchange rate on
December 31, 2009).

The terms of these agreements are generally similar to those on which each company does business
with unaffiliated parties.

Other Transactions

From time to time, we make investments together with affiliated companies and sell or buy investments to or from affiliated companies. We
have pursued joint investments in the telecommunications industry with Telmex.

We may provide, directly or through our
subsidiaries, financing to CGT, Telmex Internacional and/or Telmex.

Transactions with Other Affiliates

We have an agreement to receive consulting services from AT&T. During 2010, we will pay U.S.$7.5 million to AT&T in compensation
for its services.In 2009, 2008 and 2007 we paid U.S.$7.5 million annually to AT&T in compensation for its services.We have agreements with AT&T International that provide for AT&T International completing our
international calls to the United States and for our completing AT&T Internationals calls from the United States.

Prior to our merger with AMTEL, we had a management services agreement with AMTEL, pursuant to which we paid AMTEL U.S.$28.5 million in
2006.

Telcel purchases materials or services from a variety of companies that, according to beneficial ownership reports
filed with the SEC, are under common control with us. These services include insurance and banking services provided by Grupo Financiero Inbursa, S.A.B. de C.V. and its subsidiaries. In addition, we sell products in Mexico through the Sanborns and
Sears store chains. Telcel purchases these materials and services on terms no less favorable than it could obtain from unaffiliated parties, and would have access to other sources if our affiliates ceased to provide them on competitive terms.

DIVIDENDS

We have paid cash dividends on our shares each year since 2001. The table below sets forth the nominal amount of dividends paid per share
in each year indicated, in pesos and translated into U.S. dollars at the exchange rate on each of the respective payment dates.



|                        |  |                 |  |                   |

The
declaration, amount and payment of dividends by América Móvil is determined by majority vote of the holders of AA Shares and A Shares, generally on the recommendation of the Board of Directors, and depends on our results of operations,
financial condition, cash requirements, future prospects and other factors deemed relevant by the holders of AA Shares and A Shares. In April 2007, our shareholders authorized a dividend of Ps. 0.20 per share, which was paid in a single
installment in July 2007. In October 2007, our shareholders approved a special dividend of Ps. 1.00 per share, which was paid in a single installment in November 2007. In April 2008, our shareholders authorized a dividend of Ps. 0.26 per
share, which was paid in a single installment in July 2008. In April 2009, our shareholders authorized a dividend of Ps. 0.30 per share, which was paid in a single installment in July 2009. In December 2009, our shareholders approved a special
dividend of Ps. 0.50 per share, which was paid in a single installment in December 2009. In April 2010, our shareholders authorized a dividend of Ps. 0.32 per share, payable in two equal installments in July and November 2010. These
dividends were or will be paid on each series of our shares.

Our bylaws provide that holders of AA Shares, A Shares
and L Shares participate on a per-share basis in dividend payments and other distributions, subject to certain preferential dividend rights of holders of L Shares. See BylawsDividend Rights and BylawsPreferential Rights
of L Shares under Item 10.

LEGAL PROCEEDINGS

In each of the countries in which we conduct operations, we are party to various legal proceedings in the ordinary course of business.
These proceedings include tax, labor, antitrust, contractual matters and administrative and judicial proceedings concerning regulatory matters such as interconnection and tariffs. See Note 15 to our audited consolidated financial statements included
in this annual report.

Our concessions are generally subject to early termination for violations of their terms, including
certain service, quality, coverage standards and certain interconnection obligations. We are also party to a number of proceedings regarding our compliance with administrative rules and regulations and concession standards. As of the date of this
annual report, we believe that none of these proceedings is likely to result in the revocation of any of our material concessions.

Below is a summary of the most significant legal proceedings in which we are currently involved.

América Móvil

NatTel

The plaintiff, NatTel, LLC (NatTel) sued us and others in a Connecticut state court in the United States based on an August
2007 transaction in which we purchased shares of Oceanic from ODC St. Lucia, a subsidiary of Oceanic Digital Communications, Ltd. (ODC), in which NatTel is a minority shareholder. Under the agreement governing the transaction, the
parties placed approximately U.S.$15 million (approximately Ps. 195.9 million) in escrow with The Bank of New York, and the remaining purchase payments paid certain inter-company debt owed by Oceanic to the majority shareholders in ODCSAC
Capital Associates, LLC and SAC Capital Advisors (collectively, SAC).

In the Connecticut action, NatTel alleges
that the entire transaction was intended to deprive NatTel of its fair share of the sales proceeds, and structured so that SAC received the entire proceeds of the sale. NatTel seeks, among other things, an order that it receive the amount placed in
escrow. On February 7, 2008, we filed a motion to dismiss for lack of personal jurisdiction and insufficient service. The motion principally argues that we do not have sufficient contacts with Connecticut to support the state courts
exercise of personal jurisdiction over us. We believe we have several other meritorious defenses to NatTels claims.

Concurrently with the Connecticut action, NatTel also initiated an adversary proceeding in connection with its bankruptcy case in the
United States Bankruptcy Court for the District of Connecticut against many of the parties in the Connecticut action, including us. The adversary proceeding contains the same allegations as the Connecticut action.

After the filing of the adversary proceeding in bankruptcy court, defendants, excluding us, filed a motion in the District Court for the
District of Connecticut to withdraw the reference of the adversary proceeding, and send those proceedings to the District Court judge who had previously decided a related case against NatTel.

In April 2008, the parties to the Connecticut action agreed to stay the action pending a decision by the District Court on the motion to
withdraw. As of the date of this annual report, the District Court has yet to decide on the motion to withdraw. Accordingly, the Connecticut action remains stayed.

We have not made provisions in our financial statements for this potential liability.

Cempresa

In May or June of 2008, plaintiffs Centro Empresarial Cempresa, S.A. and Conecel Holding Limited, filed a suit in the Supreme Court of the
State of New York against numerous defendants including us and certain of our



98

##### Table of Contents

affiliates, subsidiaries and two members of our Board of Directors, asserting breach of contract, fraud, fraudulent inducement, unjust enrichment and a claim for accounting. The plaintiffs sold a
majority of their shares in our Ecuadorian subsidiary Conecel, to a subsidiary of Telmex in 2000. Telmexs holdings in Conecel were included in our spin-off from Telmex in 2000 and remain held by one of its subsidiaries. The plaintiffs kept a
minority of the shares of Conecel.

The plaintiffs assert that one of their exit strategies with respect to the minority
shares was a right to negotiate for an exchange of those shares for ours. The plaintiffs contend in the lawsuit that the defendants wrongfully deprived them of a share exchange and they seek the alleged value of our shares they claim they would have
received, which the plaintiffs assert amounts to over US$900 million (approximately Ps. 11,754 million). The plaintiffs also seek punitive damages. The plaintiffs additionally assert that the defendants purposefully misrepresented the value of the
plaintiffs minority shares to try to prevent a share exchange. In 2003, the plaintiffs voluntarily sold their minority shares to the defendants, executing comprehensive releases as part of the transactions.

The defendants filed a motion to dismiss asserting numerous defenses, including statute of limitations, release, lack of damages,
personal jurisdiction for certain defendants, and the inability to add to a contract cause of action the fraud causes of action. In December 2008, the trial court denied the motion to dismiss and the defendants appealed. The appellate court stayed
the case in the trial court. The appeal is fully briefed and oral argument took place in April 2009.

The defendants believe
they have numerous meritorious defenses to the plaintiffs claims. In addition to the defenses contained in the motion to dismiss that are issues on appeal, the defendants do not believe that our spin-off from Telmex triggered the share
exchange provision. Moreover, the defendants argue that a plain reading of the provision relating to the potential exchange of shares provides no right to a share exchange, but instead only a right to a good faith negotiation for a
period of 20 days, for a potential share exchange.

We have not made provisions in our financial statements for this potential
liability.

Telcel

CofecoSubstantial market power investigations

The Mexican competition commission, Cofeco, is conducting two substantial market power investigations into certain competitive conditions
in the mobile telecommunications market. The first of these, which commenced in December 2007, is a Cofeco-initiated investigation into whether one or more cellular operators have substantial market power in the market for termination
(interconnection) of calls made as part of the local, national and international calling party pays system. Cofeco has issued a preliminary report (dictamen preliminar) finding that each operator, including Telcel, has substantial market
power in the market for interconnection to its own network.

Interested parties have the opportunity to submit information for
Cofecos review before it issues a final report. Telcel has provided extensive information to Cofeco, and we cannot predict when Cofeco will issue a final report or whether it will modify its preliminary findings.

The second Cofeco investigation, which commenced in April 2008, was initiated by an alleged Telcel subscriber (who in fact was a
subscriber of another mobile operator) and relates to whether Telcel has substantial market power in the nationwide market for voice services. In this investigation, Cofeco issued a preliminary report (dictamen preliminar) in November 2008
finding that Telcel has substantial market power in the national mobile telephone services relevant market. The preliminary report was confirmed by the publication on February 10, 2010 in the Official Gazette of the relevant findings of the
resolution relating to the existence of substantial market power in the nationwide market for voice services.In February 2010, Telcel filed an administrative proceeding (recurso administrativo de reconsideración) before Cofeco.
Cofeco rejected the



99

##### Table of Contents

request to analyze the administrative proceeding. Telcel then filed an appeal (amparo indirecto) before an administrative judge against the rejection of the administrative proceeding and
the issuance, subscription and publication of the resolution in which relevant findings where published on February 10, 2010 in the Official Gazette.

Under the Federal Antitrust Law and the Mexican Telecommunications Law, if Cofeco makes a final finding of substantial market power
concerning an operator, Cofetel can impose on that operator specific regulations with respect to tariffs, quality of service and information. We cannot predict what regulatory steps might be taken in response to determinations by Cofeco.

CofecoMonopolistic practices investigations

Cofeco is currently conducting four separate administrative proceedings against Telcel for alleged monopolistic practices. The first two
concern alleged actions by certain distributors of Telcel in relation to the purchase and sale of cellular phones to third parties. The third proceeding concerns to certain exclusivity agreements with some content providers. In each of these
investigations, Cofeco has determined that Telcel engaged in anti-competitive behavior, and it has imposed fines totaling Ps. 6.7 million in the aggregate and ordered that the alleged behaviors terminate immediately. Telcel has challenged
Cofecos determinations and fines in the courts and no final ruling has been issued.

The fourth investigation concerns
alleged monopolistic practices in the interconnection market. After having concluded the investigation stage, in October 2009 Cofeco notified to Telcel a Notice of Apparent Liability (Oficio de Probable Responsabilidad) for carrying out
monopolistic practices in the commuted termination services relevant market.

Interested parties to this investigation have
the opportunity to submit information for Cofecos review before it issues a final resolution. Telcel has provided extensive information to Cofeco, and we cannot predict when Cofeco will issue a final resolution or whether it will modify the
Notice of Apparent Liability.

Adverse determinations against Telcel in any of these proceedings could result in material
fines, penalties or restrictions on our operations. We have not made provisions in our financial statements for these potential liabilities since at the time Telcels most recent financial statements were published, the amount of the possible
contingency could not be reasonably estimated.

Interconnection Fees

Since 2005, there has been extensive controversy in Mexico concerning the interconnection fees payable by fixed-line operators to mobile
operators on fixed-to-mobile calls. The history and current status of these proceedings is discussed under Information of the CompanyMexican OperationsRegulationsInterconnection Fees under Item 4.

February 2009 Interconnection Plan

On February 10, 2009, Cofetel published a Fundamental Technical Plan of Interconnection and Inter-operability (Plan Técnico
Fundamental de Interconexión e Interoperabilidador Plan). A description of the Plan and our legal challenges to the Plan is included under Information of the CompanyMexican
OperationsRegulationsFebruary 2009 Interconnection Plan under Item 4.

Short Message Services
(SMS)

Under the terms of its concessions for the 850 megahertz spectrum, Telcel must pay to the Mexican federal
government a royalty based on gross revenues from concessioned services. The royalty is levied at rates that vary from region to region and average approximately 6%.



100



---

##### Table of Contents

Telcel believes that short message services are value-added services, which are not
concessioned services, and that revenues from short message services should not be subject to this royalty.

In related
proceedings, Cofetel has ruled that short text messages are subject to the interconnection regulatory regime and that such services do not constitute value-added services. Telcel is currently disputing these issues in an administrative proceeding,
but has made provisions in its financial statements for this potential liability.

Trademarks Tax Assessments

On March 3, 2006, the Mexican Tax Administration Service (Servicio de Administración Tributaria, or
SAT) notified Telcel of an assessment of Ps. 281.7 million (Ps. 155.8 million plus adjustments, fines and late fees) as a result of a tax deduction made by Telcel in 2003 of Ps. 1,267.7 million in connection with royalty
payments made to another of our subsidiaries for the use of certain trademarks. In June 2007, the SAT notified us of an additional assessment of Ps. 541.5 million (Ps. 258.5 million plus adjustments, fines and late fees) as a result of a
tax deduction made by us in 2003 in connection with the aforementioned royalty payments. We and Telcel believe that these deductions were made in accordance with applicable law and have challenged the validity of these assessments.

In December 2007, the SAT notified Telcel of a new assessment of Ps. 453.6 million (Ps. 243.6 million plus adjustments, fines
and late fees) in connection with a deduction of advertising expenses made by Telcel in 2004 in the amount of Ps. 1,678.6 million. The SAT is challenging the validity of this deduction, alleging that the deduction is unfounded because Telcel is
already paying a royalty for the use of the trademarks. Telcel believes that the SATs argument is unfounded and has challenged the assessment in court.

Based on these assessments, we expect that the SAT will challenge deductions made during 2005, 2006 and 2007 for royalty payments and/or
expenses associated with the trademarks. Telcel has not made specific provisions in its financial statements for these potential liabilities.

Comcel

Voice over
IP

In March 2000, the SIC issued Resolution No. 4954, requiring Comcel to pay a fine of approximately U.S,$100
thousand (approximately Ps. 1.3 million) for alleged anti-competitive behavior. In addition to this administrative fine, the SIC ordered Comcel to pay damages to other long distance operators. The long distance operators estimated their damages to
be U.S.$70 million (approximately Ps. 904.2 million). Comcel requested an administrative review of the damages decision, which was denied in June 2000. Comcel appealed, and the appeal was rejected in November 2000. Comcel resubmitted the appeal in
February 2001. Comcel also filed a special action in court challenging the denial of the administrative review.

Following a
series of court proceedings, a Colombian appeals court in June 2002 ordered that Comcels February 2001 appeal be granted and that the administrative decision against Comcel be reviewed. After additional proceedings, the Constitutional Court
revoked the June 2002 decision and ordered the continuance of the procedure for the determination of damages to the other operators.

In January 2008, SIC determined that Comcel was required to pay the long distance operators approximately U.S.$1.8 million (approximately
Ps. 23.5 million, which represents a reduction of approximately 95% of the original amount claimed by the long distance operators). In February 2008, Comcel appealed the SICs resolution on the grounds that Comcel had not caused any damage
nor it incurred in any liability.

In June 2009, Bogotas Judicial District Court of Appeals (Tribunal Superior del
Distrito Judicial de Bogotá), confirmed SICs January 2008 resolution. As a result, Comcel timely paid US$1.8 million fine. As a result of the foregoing, this contingency has been duly terminated.

##### Table of Contents

Distributors

In February 2007, Comcel was notified of an arbitration proceeding initiated against it by Tecnoquímicas, S.A., which was a
distributor of prepaid cards of Comcel until July 2006. In the proceeding, the distributor alleges breach of contract and commercial liability on the part of Comcel. Claimant seeks to recover approximately U.S.$35 million (approximately Ps. 457.1
million) from Comcel. In July 2009, the arbitration tribunal decided that Comcel had to pay Tecnoquímicas, S.A., U.S.$13 million (approximately Ps. 169.8 million), which were timely paid by Comcel. As a result of the foregoing, this
contingency has been duly terminated.

During the second quarter of 2010, Comcel was notified of certain arbitration
proceedings initiated against it by Conexcel S.A., Globaltronics Colombia S.A., Electrophone S.A., Andino Celular S.A. and CTM S.A., all of whom were distributors of Comcel. The plaintiffs allege breach of contract and commercial liability on the
part of Comcel. Considering the aforesaid proceedings have just been notified to Comcel, as of the date of this annual report it is not possible to quantify the total plaintiffs claims.

Dominant position

In September 2009, the CRC issued a series of resolutions stating that Comcel has a dominant position in Colombias market for
outgoing mobile services. Under Colombian law, a market participant is considered to have a dominant position in a specified market if the regulators determine that it has the capacity to control the conditions in that market. The CRC made its
determination based on Comcels traffic, revenues and subscriber base. The resolutions also included regulations that would require Comcel to charge rates (excluding access fees) for mobile-to-mobile calls outside the Comcel network (off
net) that are no higher than the fees charged for mobile-to-mobile calls within the Comcel network (on net) plus access fees. The regulations were first implemented on December 4, 2009 and Comcel does not expect them to have a
material impact on its business and results of operations in Colombia.

Brazil

Anatel Inflation-Related Adjustments

Anatel has challenged each of Tess, S.A., or Tess, and ATL-Telecom Leste, S.A., or ATL, regarding the calculation
of inflation-related adjustments due under these companies concession agreements with ANATEL. 40% of the concession price under each of these agreements was due upon execution and 60% was due in three equal annual installments (subject to
inflation-related adjustments and interest) beginning in 1999. Both companies have made these concession payments, but ANATEL has rejected the companies calculation of the inflation-related adjustments and requested payment of the alleged
shortfalls.

The companies have filed declaratory and consignment actions in Brazilian courts seeking resolution of the
disputes. The court of first instance ruled against ATLs filing for declaratory action in October 2001 and ATLs filing for consignment action in September 2002. Subsequently, ATL filed appeals which are pending. The court of first
instance ruled against Tess filing for consignment action in June 2003 and against Tess filing for declaratory action in February 2009. Tess filed an appeal which is pending. In December 2008, ANATEL charged Tess approximately US$160
million (approximately Ps. 2,089.6 million). Tess filed an appeal and consequently payment has been suspended until the final ruling is issued. In March 2009, ANATEL charged ATL approximately U.S.$100 million (approximately Ps. 1,306 million). ATL
filed an appeal and consequently payment has been suspended until the final ruling is issued.

The aggregate contested amounts
are approximately US$240 million (approximately Ps. 3,134.4 million) (including potential penalties and interest). On December 31, 2005, both ATL and Tess were merged into BCP, S.A. (BCP). In April 2008, BCP changed its name to
Claro S.A. (Claro Brasil).

Claro Brasil has made specific provisions in its financial statements for these
potential liabilities.

BNDESPar

Prior to the acquisition of Telet, S.A. (Telet) and Americel, S.A. (Americel) by Telecom Americas Limited
(Telecom Americas), BNDESPar, a subsidiary of BNDES, the Brazilian development bank, had entered into investment and other shareholder agreements with Americel, Telet and certain of their significant shareholders. Under these agreements,
BNDESPar had the right, among others, to participate in the sale of shares of Telet and Americel in the event of certain transfers of control, for so long as BNDESPar held 5% of the share of capital in those companies.

In October 2003, Telecom Americas increased the capital of each of Telet and Americel and BNDESPars ownership fell below 5% from
approximately 20% in each, as it elected not to exercise its preemptive rights. Subsequently, BNDESPar sent official notices to Telet and Americel reserving its rights under the agreements with respect to certain past transfers of shares. In
November 2004, BNDESPar filed a lawsuit with the competent court of Rio de Janeiro claiming that BNDESPar is entitled to sell its shares in Telet and Americel to Telecom Americas for approximately US$164 million (approximately Ps. 2,141.8 million).
We do not believe that BNDESPar has valid grounds for its claims against Telecom Americas. We cannot provide assurance, however, that Telecom Americas will ultimately prevail in this dispute. Claro Brasil has not made specific provisions in its
financial statements for this potential liability.

Lune Patent Case

A Brazilian company claims that wireless operators in Brazil have infringed its patent over certain caller ID technology. The plaintiff
first brought a patent infringement case in a state court in Brasília, Federal Capital of Brazil, against Americel and later brought cases, as part of two separate proceedings, against other 23 defendants. Although the Company believes that
the patent does not cover the technology that is used by Americel to provide caller ID services, Americel lost the case at the trial level and on first appeal. After the judgment against Americel was rendered, a federal court in Rio de Janeiro,
Brazil, rendered a preliminary injunction decision suspending the effects of the patent, in an action filed by a supplier of caller ID technology. This injunction was later upheld on appeal, and the proceeding for judicial review on the merits of
the validity of the patent is in its initial stages.

Americel filed three special appeals against the decision of the state
court in Brasília, seeking review at the Superior Court of Justice (which is the highest court in Brazil to decide on questions of federal law) and Supreme Court (the highest court in Brazil to decide on questions of constitutional law). The
Court of Appeals has determined that two of Americels special appeals will be heard by the Superior Court of Justice. Americels request for a special appeal before the Supreme Court was denied. Americel filed a motion requesting the
reversal of this decision which is still pending.

The cases against the other operators are currently suspended as a result
of the preliminary injunction suspending the effects of the patent. The plaintiff has brought these cases to the same state trial court that heard the case against Americel, but the defendants have requested that the cases be remitted to another
court on jurisdictional grounds. The Americel judgment does not bind other state courts or federal courts of Brazil. We do not expect that there will be a resolution of these other cases within this year.

In the case against Americel, the plaintiff has requested the court to initiate the necessary proceedings for the execution of judgment.
The court has estimated that the award for damages could amount to as much as approximately US$270 million (approximately Ps. 3,526.2 million). In September 2006, the Higher Court of Justice of Brazil unanimously ruled to stay the trial, due to the
injunction suspending the validity of the patent in question. In September 2009, Lune filed before the Higher Court of Justice of Brazil a motion to revert the ruling to stay the trial. However, Americel obtained a favorable resolution that
maintained the decision to stay the trial until a ruling has been issued in the process held before the federal court in Rio de Janeiro. Lune has challenged the resolution before the Superior Court, but the resolution to stay the trial was
unanimously upheld. We expect



103



---

##### Table of Contents

that the trial will remain stayed as long as the patent remains suspended. Furthermore, Americel benefits from a limited contractual indemnity from its equipment suppliers (Nortel Networks) in
respect of trademark infringement. The process remains suspended by the Superior Court of Justice. Americel has not made specific provisions in its financial statements to cover these potential liabilities.

Tax Assessments against Americel

In December 2005, the Brazilian Federal Revenue Service (Secretaria da Receita Federal do Brasil) issued three tax assessments
against Americel in respect of withholding income taxes and PIS and COFINS taxes (contributions levied on gross revenue) for 2000 through 2005. As of February 2010, the total amount of the tax assessments was R$ 289 million
(approximately Ps. 2,175.5 million), including R$ 89.9 million (approximately Ps. 673.4 million) of taxes and contributions plus fines and interest. Americel has challenged these assessments, and its challenge is pending before the Brazilian
Taxpayers Council (Conselho Administrativo de Recursos Fiscais) in Brasilia. Americel did not make any specific provisions in its financial statements to cover these potential liabilities.

Tax Assessments against ATL

In March 2006, the Brazilian Federal Revenue Service issued two tax assessments against ATL in respect of certain tax credits claimed by
ATL and derived from non-cumulative contributions levied on gross income (PIS and COFINS). Under the Brazilian tax legislation, the calculation and payment of PIS and COFINS has two different regimes, the cumulative and non-cumulative regimes. The
applicability of a regime depends on the nature of the company and its business sector. The cumulative regime applies to revenues derived from the provision of telecommunications services, while the sale of handsets is taxed under the non-cumulative
regime. The non-cumulative regime is based on the value-added concept and allows the taxpayer to claim tax credits corresponding to preceding transactions. ATL (as well as other our Brazilian subsidiaries) offsets the tax credit derived from the
non-cumulative regime for the sale of handsets (the balance between the purchase and the sale of handsets), against contributions owed under the cumulative regime. The Brazilian Federal Revenue Service is arguing that tax credits derived from the
non-cumulative regime may not be used to offset contributions owed under the cumulative regime. The total amount of the tax assessments is approximately R$75 million (approximately Ps. 562.5 million), including R$24.1 million (approximately Ps.
180.8 million) of taxes and contributions plus R$30.8 million (approximately Ps. 231 million) of fines and interest. Claro Brasil has challenged these assessments, and the challenge is pending before the Brazilian Taxpayers Council.

On December 31, 2005, ATL was merged into BCP. In April 2008, BCP changed its name to Claro Brasil.

Claro Brasil did not make any specific provisions in its financial statements to cover these potential liabilities.

Conecel

Tax
Assessments

During 2008, Conecel filed administrative proceedings before the Ecuadorian Revenue Services(Servicio
de Rentas Internas de Ecuador, or the SRI), challenging US$127 million (approximately Ps. 1,658.6 million) of certain tax assessments notified by the SRI amounting to U.S.$138 million (not including interest and penalties)
(approximately Ps. 1,802.3) which related to special consumption (ICE), value-added, income and withholding taxes for the years 2003 to 2006. In March 2008, Conecel paid to the SRI U.S.$14.3 million (approximately Ps. 186.8 million) in respect of
the aforesaid tax assessments.

In December 2008, the SRI notified Conecel of a resolution that denied the challenges filed by
Conecel against the tax assessments. As a result of the foregoing, on January 15, 2009, Conecel filed a lawsuit before a Tax Court in Guayaquil (Tribunal Distrital de lo Fiscal de Guayaquil) challenging the tax assessments, attaching a
bank guarantee of US$12.7 (approximately Ps. 165.9 million), which represented 10% of the contested amount.

In May, 2009, the SRI filed the answer to the complaint. Immediately thereafter, the Tax
Court opened the evidentiary stage of the proceedings and summoned the parties to several document exhibition hearings, which took place in Conecel and the SRI. Accountant experts, certified by the parties, were also summoned to the hearings and
were responsible for issuing expert opinions as to the document exhibition process. The latest expert opinion was filed before the Tax Court on January 27, 2010.

TRADING ON THE MEXICAN STOCK EXCHANGE

The Mexican Stock Exchange, located in Mexico City, is the only stock exchange in Mexico. Founded in 1907, it is organized as a
corporation and operates under a concession from the Ministry of Finance and Public Credit (Secretaría de Hacienda y Crédito Público, or SHCP). Trading on the Mexican Stock Exchange takes place principally
through automated systems between the hours of 8:30 a.m. and 4:00 p.m. Mexico City time, each business day. The Mexican Stock Exchange operates a system of automatic suspension of trading in shares of a particular issuer as a means of controlling
excessive price volatility, but under current regulations this system does not apply to securities such as the A Shares or the L Shares that are directly or indirectly (for example, through ADSs) quoted on a stock exchange (including for these
purposes NASDAQ) outside Mexico.

Settlement is effected three business days after a share transaction on the Mexican Stock
Exchange. Deferred settlement, even by mutual agreement, is not permitted without the approval of the CNBV. Most securities traded on the Mexican Stock Exchange, including ours, are on deposit with S.D. Indeval Institución para el
Depósito de Valores, S.A. de C.V., a privately owned securities depositary that acts as a clearinghouse for Mexican Stock Exchange transactions.

Share and A Share entitles the holder thereof to one vote at any meeting of our shareholders. Each L Share entitles the holder to one vote at any meeting at which holders of L Shares are entitled to vote. Holders of L Shares are entitled to vote

Under Mexican law, holders of shares of any series are also entitled to vote
as a class on any action that would prejudice the rights of holders of shares of such series, and a holder of shares of such series would be entitled to judicial relief against any such action taken without such a vote. There are no other procedures
for determining whether a proposed shareholder action requires a class vote, and Mexican law does not provide extensive guidance on the criteria to be applied in making such a determination.

Shareholders Meetings

General shareholders meetings may be ordinary meetings or extraordinary meetings. Extraordinary general meetings are those called to
consider certain matters specified in Article 182 of the Mexican General Corporations Law, including, principally, amendments of the bylaws, liquidation, merger and transformation from one type of company to another, as well as to consider the
removal of our shares from listing on the Mexican Stock Exchange or any foreign stock exchange. General meetings called to consider all other matters are ordinary meetings. The two directors elected by the holders of L Shares are elected at a
special meeting of holders of L Shares. All other matters on which holders of L Shares are entitled to vote would be considered at an extraordinary general meeting.

A special meeting of the holders of L Shares must be held each year for the election or ratification of directors. An ordinary general
meeting of the holders of AA Shares and A Shares must be held each year to consider the approval of the financial statements for the preceding fiscal year, to elect or ratify directors and to determine the allocation of the profits of the preceding
year. An ordinary general shareholder meeting of all shareholders, including holders of L Shares, must be held to consider the approval of all transactions that represent 20% or more of our consolidated assets within the corresponding immediately
preceding quarter of any fiscal year.

##### Table of Contents

The quorum for an ordinary general meeting of the AA Shares and A Shares is 50% of such
shares, and action may be taken by a majority of the shares present. If a quorum is not available, a second meeting may be called at which action may be taken by a majority of the AA Shares and A Shares present, regardless of the number of such
shares. Special meetings of holders of L Shares are governed by the same rules applicable to ordinary general meetings of holders of AA Shares and A Shares. The quorum for an extraordinary general meeting at which holders of L Shares may not vote is
75% of the AA Shares and A Shares, and the quorum for an extraordinary general meeting at which holders of L Shares are entitled to vote is 75% of the outstanding capital stock. If a quorum is not available in either case, a second meeting may be
called and action may be taken, provided a majority of the shares entitled to vote is present. Whether on first or second call, actions at an extraordinary general meeting may be taken by a majority vote of the AA Shares and A Shares outstanding
and, on matters which holders of L Shares are entitled to vote, a majority vote of all the capital stock.

Holders of 20% of
our outstanding capital stock may have any shareholder action set aside by filing a complaint with a court of law within 15 days after the close of the meeting at which such action was taken and showing that the challenged action violates Mexican
law or our bylaws. In addition, any holder of our capital stock may bring an action at any time within five years challenging any shareholder action. Relief under these provisions is only available to holders:



| |  |  | who were entitled to vote on, or whose rights as shareholders were adversely affected by, the challenged shareholder action; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------



| |  |  | whose shares were not represented when the action was taken or, if represented, were voted against it.
| | - |  | ------------------------------------------------------------------------------------------------------

Shareholders meetings may be called by the Board of Directors, its chairman, its corporate secretary, the Chairman of the Audit and
Corporate Practices Committee or a court. The Chairman of the Board of Directors or the Chairman of the Audit and Corporate Practices Committee may be required to call a meeting of shareholders by the holders or 10% of the outstanding capital stock.
Notice of meetings must be published in the Official Gazette or a newspaper of general circulation in Mexico City at least 15 days prior to the meeting.

In order to attend a meeting, shareholders are required to deposit their shares at the office of our corporate secretary with a Mexican
or foreign banking institution or with a Mexican exchange broker. The depositary for the L Share ADSs and the A Share ADSs does not satisfy this requirement, so ADS holders are not entitled to attend shareholder meetings. However, ADS holders may
still vote through the depositary.

Dividend Rights

At the annual ordinary general meeting of holders of AA Shares and A Shares, the Board of Directors submits our financial statements for
the previous fiscal year, together with a report thereon by the Board, to the holders of AA Shares and A Shares for approval. The holders of AA Shares and A Shares, once they have approved the financial statements, determine the allocation of our
net profits for the preceding year. They are required by law to allocate 5% of such net profits to a legal reserve, which is not thereafter available for distribution except as a stock dividend, until the amount of the legal reserve equals 20% of
our capital stock. The remainder of net profits is available for distribution.

All shares outstanding at the time a dividend
or other distribution is declared are entitled to participate in such dividend or other distribution, subject to certain preferential rights of the L Shares. See Preferential Rights of L Shares under this Item 10.

##### Table of Contents

Preferential Rights of L Shares

Holders of L Shares are entitled to receive a cumulative preferred annual dividend of 0.00042 pesos per share before any dividends are
payable in respect of any other class of América Móvil capital stock. If we pay dividends with respect to any fiscal year in addition to the L Share preferred dividend, such dividends must be allocated:



| |  |  | first, to the payment of dividends with respect to the A Share and AA Shares, in an equal amount per share, up to the amount of the L Share preferred
dividend, and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | second, to the payment of dividends with respect to all classes of América Móvil shares such that the dividend per share is equal.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------

Upon our liquidation, holders of L Shares will be entitled to a liquidation preference equal to:



| |  |  | accrued but unpaid L Share preferred dividends, plus
| | - |  | ----------------------------------------------------



| |  |  | 0.00833 pesos per share (representing the capital attributable to such shares as set forth in our bylaws) before any distribution is made in respect of
our other capital stock in accordance with Article 113 of the Mexican General Corporations Law.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Following
payment in full of any such amount, holders of AA Shares and A Shares are entitled to receive, if available, an amount per share equal to the liquidation preference paid per L Share. Following payment in full of the foregoing amounts, all
shareholders share equally, on a per share basis, in any remaining amounts payable in respect of our capital stock.

Limitation on Capital
Increases

Our bylaws require that any capital increase be represented by new shares of each series in proportion to the
number of shares of each series outstanding.

Preemptive Rights

In the event of a capital increase, except in certain circumstances such as mergers, convertible debentures, public offers and placement
of repurchased shares, a holder of existing shares of a given series has a preferential right to subscribe for a sufficient number of shares of the same series to maintain the holders existing proportionate holdings of shares of that series.
Preemptive rights must be exercised within the next 15 calendar days following the publication of notice of the capital increase in the Official Gazette and a newspaper of general circulation in Mexico City. Under Mexican law, preemptive rights
cannot be traded separately from the corresponding shares that give rise to such rights. As a result, there is no trading market for the rights in connection with a capital increase. Holders of ADSs may exercise preemptive rights only through the
depositary. We are not required to take steps that may be necessary to make this possible.

Limitations on Share Ownership

Our bylaws provide that at least 20% of our capital stock must consist of AA Shares. Our bylaws also provide that A Shares and L Shares
together cannot represent more than 80% of our capital stock. AA Shares can only be held or acquired by:



| |  |  | Mexican citizens;
| | - |  | -----------------



| |  |  | Mexican corporations whose capital stock is held completely by Mexican citizens;
| | - |  | --------------------------------------------------------------------------------



| |  |  | Mexican corporations in which at least 51% of their capital stock may only be held or acquired by (i) Mexican citizens or (ii) Mexican
corporations;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------



111

##### Table of Contents

| |  |  | Mexican credit and insurance companies;
| | - |  | ---------------------------------------



| |  |  | Mexican investment companies operating under the Investment Companies Law (Ley de Sociedades de Inversión) and Mexican institutional
investors as defined in the Mexican Securities Market Law; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Trusts expressly permitted to acquire AA Shares in accordance with Mexican law and in which (i) the majority of the trustees rights are held
by Mexican citizens, corporations whose capital stock is held by Mexican citizens in its majority, and Mexican credit, insurance and investment companies, or (ii) the AA Shares controlled by the trust represent a minority of the outstanding AA
Shares and are voted in the same manner as the majority of the outstanding AA Shares.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

If foreign
governments or states acquire our AA Shares, such shares would immediately be rendered without effect or value.

Non-Mexican
investors cannot hold AA Shares except through trusts that effectively neutralize their votes. AT&T, Inc., one of our shareholders, holds its AA Shares through a trust that has been approved by relevant authorities in Mexico for this purpose.

At a general extraordinary meeting held in Mexico City on March 17, 2010, the shareholders of América
Móvil voted to approve an amendment to its bylaws (estatutos sociales) that added a provision called a foreign exclusion clause. Under the foreign exclusion clause, ownership of América Móvil shares is restricted to
holders that qualify as Mexican investors under Mexican law. The foreign exclusion clause does not apply to the L Shares, and under transitional provisions adopted by the shareholders it does not limit foreign ownership of A Shares outstanding as of
the date of the shareholders meeting approving the amendment.

Restrictions on Certain Transactions

Our bylaws provide that any transfer of more than 10% of the combined A Shares and AA Shares, effected in one or more transactions by any
person or group of persons acting in concert, requires prior approval by our Board of Directors. If the Board of Directors denies such approval, however, Mexican law and our bylaws require it to designate an alternate transferee, who must pay market
price for the shares as quoted on the Mexican Stock Exchange.

Further, the ordinary shareholders meeting shall approve all
transactions that represent 20% or more of our consolidated assets within the corresponding immediately preceding quarter of any fiscal year.

Restrictions on Deregistration in Mexico

Our shares are registered with the National Securities Registry maintained by the CNBV, as required under the Mexican Securities Market
Law and regulations issued by the CNBV.

If we wish to cancel our registration, or if it is cancelled by the CNBV, we are
required to conduct a public offer to purchase all the outstanding shares prior to such cancellation. Such offer shall be addressed exclusively to those persons other than the members of the controlling group of shareholders, who were shareholders
or holders of other securities representing such shares (i) as of the date set forth by the CNBV, if the registration is cancelled by resolution thereof, or (ii) as of the date of the resolution adopted by the general extraordinary
shareholders meeting, if the registration is cancelled voluntarily.

Our bylaws provide that if, after the public offer is
concluded, there are still outstanding shares held by the general public, América Móvil will be required to create a trust for a period of six months, into which we will be required to contribute funds in an amount sufficient to
purchase, at the same price as the offer price, the number of outstanding shares held by the general public that did not consent to the offer.



112



---

##### Table of Contents

Unless the CNBV authorizes otherwise, upon the prior approval of the Board of Directors
which must take into account the opinion of the audit and corporate practices committee, the offer price will be the higher of: (i) the average of the closing price during the previous 30 days on which the shares may have been quoted, or
(ii) the book value of the shares in accordance with the most recent quarterly report submitted to the CNBV and to the Mexican Stock Exchange.

The voluntary cancellation of the registration shall be subject to (i) the prior authorization of the CNBV, and (ii) the
authorization of not less than 95% of the outstanding capital stock in a general extraordinary shareholders meeting.

Tender Offer Rules

Our bylaws provide that any purchasers or group of purchasers that obtain or increase a significant participation
(i.e., 30% or more) in the capital stock of the company, without conducting a previous public offer in accordance with the applicable rules issued by the CNBV, would not have the right to exercise the corporate rights of their shares, and
that the company will not register such shares in the share registry book.

Other Provisions

Variable capital.    We are permitted to issue shares constituting fixed capital and shares constituting
variable capital. All of our outstanding shares of capital stock constitute fixed capital. The issuance of variable-capital shares, unlike the issuance of fixed-capital shares, does not require an amendment of the bylaws, although it does require a
majority vote of the AA Shares and the A Shares.

Forfeiture of shares.    As required by Mexican
law, our bylaws provide that any alien who at the time of incorporation or at any time thereafter acquires an interest or participation in the capital of the corporation shall be considered, by virtue thereof, as Mexican in respect thereof and shall
be deemed to have agreed not to invoke the protection of his own government, under penalty, in case of breach of such agreement, of forfeiture to the nation of such interest or participation. Under this provision a non-Mexican shareholder is deemed
to have agreed not to invoke the protection of his own government by asking such government to interpose a diplomatic claim against the Mexican government with respect to the shareholders rights as a shareholder, but is not deemed to have
waived any other rights it may have, including any rights under the U.S. securities laws, with respect to its investment in América Móvil. If the shareholder invokes such governmental protection in violation of this agreement, its
shares could be forfeited to the Mexican government. Mexican law requires that such a provision be included in the bylaws of all Mexican corporations unless such bylaws prohibit ownership of shares by non-Mexican persons.

Exclusive jurisdiction.    Our bylaws provide that legal actions relating to the execution, interpretation or
performance of the bylaws shall be brought only in Mexican courts.

Duration.    América
Móvils existence under the bylaws continues indefinitely.

Purchase of our own
shares.    According to the bylaws, we may repurchase our shares on the Mexican Stock Exchange at any time at the then prevailing market price. Any such repurchase must conform to guidelines established by the Board of
Directors, and the amount available to repurchase shares must be approved by the general ordinary shareholders meeting. The economic and voting rights corresponding to repurchased shares may not be exercised during the period in which we own such
shares, and such shares are not deemed to be outstanding for purposes of calculating any quorum or vote at any shareholders meeting during such period.

Conflict of interest.    A shareholder that votes on a business transaction in which its
interest conflicts with América Móvils may be liable for damages, but only if the transaction would not have been approved without its vote.



113

##### Table of Contents

Appraisal rights.    Whenever the shareholders approve a change
of corporate purposes, change of nationality of the corporation or transformation from one type of company to another, any shareholder entitled to vote on such change that has voted against it may withdraw from América Móvil and
receive the book value attributable to its shares, provided it exercises its right within 15 days following the adjournment of the meeting at which the change was approved.

Rights of Shareholders

The protections afforded to minority shareholders under Mexican law are different from those in the United States and many other
jurisdictions. The substantive law concerning fiduciary duties of directors has not been the subject of extensive judicial interpretation in Mexico, unlike many states in the United States where duties of care and loyalty elaborated by judicial
decisions help to shape the rights of minority shareholders. Mexican civil procedure does not contemplate class actions, which permit shareholders in U.S. courts to bring actions on behalf of other shareholders. Shareholders cannot challenge
corporate action taken at a shareholders meeting unless they meet certain procedural requirements, as described above under Shareholders Meetings.

As a result of these factors, in practice it may be more difficult for our minority shareholders to enforce rights against us or our
directors or controlling shareholders than it would be for shareholders of a U.S. company.

In addition, under the U.S.
securities laws, as a foreign private issuer we are exempt from certain rules that apply to domestic U.S. issuers with equity securities registered under the U.S. Securities Exchange Act of 1934, including the proxy solicitation rules and the rules
requiring disclosure of share ownership by directors, officers and certain shareholders. We are also exempt from the corporate governance requirements of the NYSE and NASDAQ, except that since July 2005 we are subject to the requirements concerning
audit committees and independent directors adopted pursuant to the Sarbanes-Oxley Act of 2002. For a comparison of our corporate governance policies and the corporate governance requirements of the NYSE and NASDAQ, see Corporate
Governance under this Item 10.

Enforceability of Civil Liabilities

América Móvil is organized under the laws of Mexico, and most of our directors, officers and controlling persons reside
outside the United States. In addition, all or a substantial portion of our assets and their assets are located in Mexico. As a result, it may be difficult for investors to effect service of process within the United States on such persons. It
may also be difficult to enforce against them, either inside or outside the United States, judgments obtained against them in U.S. courts, or to enforce in U.S. courts judgments obtained against them in courts in jurisdictions outside the United
States, in any action based on civil liabilities under the U.S. federal securities laws. There is doubt as to the enforceability against such persons in Mexico, whether in original actions or in actions to enforce judgments of U.S. courts, of
liabilities based solely on the U.S. federal securities laws.

CERTAIN CONTRACTS

Telcel holds concessions granted by the SCT with respect to its licenses in each of the nine regions in Mexico. See Mexican
OperationsRegulation under Item 4. A number of our subsidiaries and affiliates also hold concessions granted by regulatory authorities in the countries in which they operate. See Mexican Operations, Non-Mexican
Operations and Other Investments under Item 4.

Our agreements with related parties are described in
Related Party Transactions under Item 7.

EXCHANGE CONTROLS

Mexico has had a free market for foreign exchange since 1991, and the government has allowed the peso to float freely against the U.S.
dollar since December 1994. There can be no assurance that the government will maintain its current foreign exchange policies. See Exchange Rates under Item 3.

TAXATION

The following summary contains a description of certain Mexican federal and U.S. federal income tax consequences of the acquisition,
ownership and disposition of L Shares, A Shares, L Share ADSs or A Share ADSs, but it does not purport to be a comprehensive description of all of the tax considerations that may be relevant to a decision to purchase, hold or sell shares or ADSs.

The Convention for the Avoidance of Double Taxation and the Prevention of Fiscal Evasion and the Protocols thereto between
the United States and Mexico entered into force on January 1, 1994 and has been amended by an additional protocol that entered into force on July 3, 2003 (together, the Tax Treaty). The United States and Mexico have also
entered into an agreement concerning the exchange of information with respect to tax matters.

This discussion does not
constitute, and should not be considered as, legal or tax advice to holders. The discussion is for general information purposes only and is based upon the federal tax laws of Mexico (including the Mexican Income Tax Law and the Mexican Federal Tax
Code) and the United States as in effect on the date of this annual report (including the Tax Treaty), which are subject to change, and such changes may have retroactive effect. Holders of shares or ADSs should consult their own tax advisers as to
the Mexican, U.S. or other tax consequences of the purchase, ownership and disposition of shares or ADSs, including, in particular, the effect of any foreign, state or local tax laws.

Mexican Tax Considerations

The following is a general summary of the principal consequences under the Mexican Income Tax Law (Ley del Impuesto sobre la Renta,
or the Mexican Income Tax Law) and rules and regulations thereunder, as currently in effect, of an investment in shares or ADSs by a holder that is not a resident of Mexico and that will not hold shares or ADSs or a beneficial interest
therein in connection with the conduct of a trade or business through a permanent establishment in Mexico (a nonresident holder).

For purposes of Mexican taxation, the definition of residence is highly technical and residence arises in several situations. Generally,
an individual is a resident of Mexico if he or she has established his or her home or center of vital interests in Mexico, and a corporation is considered a resident if it has its place of effective management in Mexico. However, any determination
of residence should take into account the particular situation of each person or legal entity.

If a legal entity or an
individual is deemed to have a permanent establishment in Mexico for Mexican tax purposes, all income attributable to that permanent establishment will be subject to Mexican income taxes, in accordance with applicable tax laws.

This summary does not address all of the Mexican tax consequences that may be applicable to specific holders of the shares (including a
holder that controls the Company, an investor that holds 10% or more of the shares or holders that constitute a group of persons for purposes of Mexican law). It also does not purport to be a comprehensive description of all the Mexican tax
considerations that may be relevant to a decision to purchase, own or dispose of the shares. In particular, this summary does not describe any tax consequences arising under the laws of any state, locality, municipality or taxing jurisdiction other
than certain federal laws of Mexico.

##### Table of Contents

Tax Treaties

Provisions of the Tax Treaty that may affect the taxation of certain U.S. holders (as defined below) are summarized below.

The Mexican Income Tax Law has established procedural requirements for a nonresident holder disposing of his shares to be entitled to the
benefits under any of the tax treaties to which Mexico is a party. These procedural requirements include among others the obligation to (i) prove tax treaty residence, (ii) present tax calculations made by authorized certified public
accountants, and (iii) appoint representatives in Mexico for taxation purposes.

Payment of Dividends

Dividends, either in cash or in kind, paid with respect to the L Shares, A Shares, L Share ADSs or A Share ADSs will
not be subject to Mexican withholding tax.

Taxation of Dispositions

Under current Mexican law and regulations, there is no basis for the Mexican tax authorities to impose taxes on income realized by a
nonresident holder from a disposition of shares or ADSs which are registered in the Mexican Stock Exchange, provided that (i) the transaction is carried out through (a) the Mexican Stock Exchange, (b) other securities exchanges or
markets approved by the SHCP, or (c) other securities exchanges or markets with ample securities trading that are located in countries with which Mexico has entered into an income tax treaty, such as the NYSE, the FWB Frankfurter
Wertpapierbörse, NASDAQ and the Mercado de Valores Latinoamericanos en Euros (LATIBEX), and (ii) certain other requirements are met, including that the acquisition was made pursuant to a non-restricted open market offer. Sales
or other dispositions of shares or ADSs carried out in other circumstances generally are subject to Mexican tax, except to the extent that a nonresident holder is eligible for benefits under an income tax treaty to which Mexico is a party.

Pursuant to the Tax Treaty, gains realized by a U.S. resident which is eligible to receive benefits pursuant to the Tax
Treaty from the sale or other disposition of shares, even if the sale or disposition is not carried out under the circumstances described in the preceding paragraphs, will not be subject to Mexican income tax, provided that the gains are not
attributable to a permanent establishment or a fixed base in Mexico, and further provided that such U.S. holder owned less than 25% of the shares representing our capital stock (including ADSs), directly or indirectly, during the 12-month period
preceding such disposition. U.S. residents should consult their own tax advisors as to their possible eligibility under the treaty.

Gains realized by other nonresident holders that are eligible to receive benefits pursuant to other income tax treaties to which Mexico
is a party may be exempt from Mexican income tax in whole or in part. Non-U.S. holders should consult their own tax advisers as to their possible eligibility under such treaties.

If a corporation is a resident in a tax haven (as defined by the Mexican Income Tax Law), the applicable rate will be 40% on the gross
income obtained.

Other Mexican Taxes

Under certain circumstances, a nonresident holder will not be liable for estate, inheritance or similar taxes with respect to its holdings
of shares or ADSs; provided, however, that gratuitous transfers of shares may in certain circumstances result in imposition of a Mexican tax upon the recipient. There are no Mexican stamp, issue registration or similar taxes payable by a nonresident
holder with respect to shares or ADSs.

##### Table of Contents

U.S. Federal Income Tax Considerations

The following is a summary of certain U.S. federal income tax consequences to U.S. holders (as defined below) of the acquisition,
ownership and disposition of shares or ADSs. The summary does not purport to be a comprehensive description of all of the tax consequences of the acquisition, ownership or disposition of shares or ADSs. The summary applies only to U.S. holders that
will hold their shares or ADSs as capital assets and does not apply to special classes of U.S. holders such as dealers in securities or currencies, holders with a functional currency other than the U.S. dollar, holders of 10% or more of our voting
shares (whether held directly or through ADSs or both), tax-exempt organizations, banks or other financial institutions, holders liable for the alternative minimum tax, securities traders electing to account for their investment in their shares or
ADSs on a mark-to-market basis, entities that are treated for U.S. federal income tax purposes as partnerships or other pass-through entities, and persons holding their shares or ADSs in a hedging transaction or as part of a straddle or conversion
transaction.

For purposes of this discussion, a U.S. holder is a holder of shares or ADSs that is:



| |  |  | a citizen or resident of the United States of America,
| | - |  | ------------------------------------------------------



| |  |  | a corporation (or other entity taxable as a corporation) organized under the laws of the United States of America or any state thereof, or
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | otherwise subject to U.S. federal income taxation on a net income basis with respect to the shares or ADSs.
| | - |  | -----------------------------------------------------------------------------------------------------------

Each U.S. holder should consult such holders own tax advisor concerning the overall tax consequences to it of the ownership or
disposition of shares or ADSs that may arise under foreign, state and local laws.

Treatment of ADSs

In general, a U.S. holder of ADSs will be treated as the owner of the shares represented by those ADSs for U.S.
federal income tax purposes. Deposits or withdrawals of shares by U.S. holders in exchange for ADSs will not result in the realization of gain or loss for U.S. federal income tax purposes. U.S. holders that withdraw any shares should consult their
own tax advisors regarding the treatment of any foreign currency gain or loss on any pesos received in respect of such shares.

Taxation of Distributions

In this discussion, we use the term dividends to mean distributions paid out of our current or accumulated earnings and
profits with respect to shares or ADSs. In general, the gross amount of any dividends will be includible in the gross income of a U.S. holder as ordinary income on the day on which the dividends are received by the U.S. holder, in the case of
shares, or by the depositary, in the case of ADSs. Dividends will be paid in pesos and will be includible in the income of a U.S. holder in a U.S. dollar amount calculated by reference to the exchange rate in effect on the date that they are
received by the U.S. holder, in the case of shares, or by the depositary, in the case of ADSs (regardless of whether such pesos are in fact converted into U.S. dollars on such date). If such dividends are converted into U.S. dollars on the date of
receipt, a U.S. holder generally should not be required to recognize foreign currency gain or loss in respect of the dividends. U.S. holders should consult their own tax advisors regarding the treatment of foreign currency gain or loss, if any, on
any pesos received by a U.S. holder or depositary that are converted into U.S. dollars on a date subsequent to receipt. Dividends paid by us will not be eligible for the dividends-received deduction allowed to corporations under the U.S. Internal
Revenue Code of 1986, as amended (the Code).

Subject to certain exceptions for short-term and hedged positions,
the U.S. dollar amount of dividends received by an individual prior to January 1, 2011 with respect to the ADSs will be subject to taxation at a



117



---

##### Table of Contents

maximum rate of 15% if the dividends are qualified dividends. Dividends paid on the ADSs will be treated as qualified dividends if (i) the ADSs are readily tradable on an
established securities market in the United States and (ii) we were not, in the year prior to the year in which the dividend was paid, and are not, in the year in which the dividend is paid a passive foreign investment company
(PFIC). The ADSs are listed on the New York Stock Exchange, and will qualify as readily tradable on an established securities market in the United States so long as they are so listed. Based on our audited consolidated financial
statements and relevant market and shareholder data, we believe that we were not treated as a PFIC for U.S. federal income tax purposes with respect to the 2008 or 2009 taxable year. In addition, based on our audited consolidated financial
statements and our current expectations regarding the value and nature of our assets, the sources and nature of our income, and relevant market and shareholder data, we do not anticipate becoming a PFIC for our 2010 taxable year. Based on existing
guidance, it is not entirely clear whether dividends received with respect to the shares will be treated as qualified dividends, because the shares are not themselves listed on a U.S. exchange. In addition, the U.S. Treasury has announced its
intention to promulgate rules pursuant to which holders of ADSs or common stock and intermediaries though whom such securities are held will be permitted to rely on certifications from issuers to establish that dividends are treated as qualified
dividends. Because such procedures have not yet been issued, it is not clear whether we will be able to comply with them. Holders of ADSs and common shares should consult their own tax advisors regarding the availability of the reduced dividend tax
rate in the light of their own particular circumstances.

Distributions of additional shares or ADSs to U.S. holders with
respect to their shares or ADSs that are made as part of a pro rata distribution to all of our shareholders generally will not be subject to U.S. federal income tax.

Taxation of Dispositions

A U.S. holder generally will recognize capital gain or loss on the sale or other disposition of the shares or ADSs in an amount equal to
the difference between the U.S. holders basis in such shares or ADSs (in U.S. dollars) and the amount realized on the disposition (in U.S. dollars, determined at the spot rate on the date of disposition if the amount realized is denominated in
a foreign currency). Gain or loss recognized by a U.S. holder on such sale or other disposition generally will be long-term capital gain or loss if, at the time of disposition, the shares or ADSs have been held for more than one year. Long-term
capital gain recognized by a U.S. holder that is an individual is taxed at reduced rates of tax. The deduction of a capital loss is subject to limitations for U.S. federal income tax purposes.

Gain, if any, realized by a U.S. holder on the sale or other disposition of the shares or ADSs generally will be treated as U.S. source
income for U.S. foreign tax credit purposes. Consequently, if a Mexican withholding tax is imposed on the sale or disposition of the shares, a U.S. holder that does not receive significant foreign source income from other sources may not be able to
derive effective U.S. foreign tax credit benefits in respect of these Mexican taxes. U.S. holders should consult their own tax advisors regarding the application of the foreign tax credit rules to their investment in, and disposition of, the shares.

Information Reporting and Backup Withholding

Dividends on, and proceeds from the sale or other disposition of, the shares or ADSs paid to a U.S. holder generally may be subject to the
information reporting requirements of the Code and may be subject to backup withholding unless the holder:



| |  |  | establishes that it is a corporation or other exempt holder, or
| | - |  | ---------------------------------------------------------------



| |  |  | provides an accurate taxpayer identification number on a properly completed Internal Revenue Service Form W-9 and certifies that no loss of exemption
from backup withholding has occurred.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The amount of any backup withholding from a payment to a holder will
be allowed as a credit against the U.S. holders U.S. federal income tax liability and may entitle such holder to a refund, provided that certain required information is furnished to the Service.

Distributions.    A holder of shares or ADSs that is, with respect to the United States, a foreign corporation
or a non-resident alien individual (a non-U.S. holder) generally will not be subject to U.S. federal income or withholding tax on dividends received on shares or ADSs, unless such income is effectively connected with the conduct by the
holder of a U.S. trade or business.

Dispositions.    A non-U.S. holder of shares or ADSs will not
be subject to U.S. federal income or withholding tax on gain realized on the sale of shares or ADSs, unless:



| |  |  | such gain is effectively connected with the conduct by the holder of a U.S. trade or business, or
| | - |  | -------------------------------------------------------------------------------------------------



| |  |  | in the case of gain realized by an individual holder, the holder is present in the United States for 183 days or more in the taxable year of the sale
and certain other conditions are met.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Information Reporting and Backup
Withholding.    Although non-U.S. holders generally are exempt from backup withholding, a non-U.S. holder may be required to comply with certification and identification procedures in order to establish its exemption
from information reporting and backup withholding.

|Item 11. | Quantitative and Qualitative Disclosures about Market Risk
|-------- | ----------------------------------------------------------

EXCHANGE RATE AND INTEREST RATE RISKS

We are exposed to market risk principally from changes in interest rates and currency exchange rates. Interest rate risk exists
principally with respect to our net financial liabilities bearing interest at floating rates. Interest rate risk also exists with respect to the fair value of fixed-rate financial assets and liabilities. Exchange rate risk exists with respect to our
financial assets and liabilities denominated in currencies other than Mexican pesos, principally on our U.S. dollar denominated debt. We are also subject to exchange rate risks with respect to our investments outside Mexico.

At December 31, 2009, we had approximately Ps. 20,805 million (as compared to Ps. 13,942 million as of December 31,
2008) in financial assets denominated in currencies other than Mexican pesos, principally consisting of cash, short-term investments and investments in financial instruments, and approximately Ps. 84,546 million (as compared to Ps. 105,675
million as of December 31, 2008) in financial liabilities denominated in currencies other than Mexican pesos, consisting of debt and accounts payable. This decrease in financial liabilities denominated in currencies other than Mexican pesos was
primarily due to repayment of committed revolving facilities. Approximately 67.4% of our non-peso indebtedness as of December 31, 2009 was denominated in U.S. dollars. As of December 31, 2009, we had Ps. 27,155 million (as compared to
Ps. 58,887 million as of December 31, 2008) of debt that bore interest at floating rates. This decrease in debt bearing interest at floating rates was primarily due to reductions in bank facilities and amortization of securities bearing
floating rates.

We regularly assess our interest rate and currency exchange exposures and determine whether to adjust our
position. We may use derivative financial instruments as an economic hedge to adjust our exposures. Our derivatives use practices vary from time to time depending on our judgment of the level of risk, expectations as to interest or exchange rate
movements and the costs of using derivative financial instruments. See Operating And Financial Review And ProspectsRisk Management under Item 5. We have also used derivative financial instruments from to time to seek to reduce
our costs of financing. We may stop using derivative instruments or modify our practices at any time.

SENSITIVITY ANALYSIS DISCLOSURES

The potential increase in net debt and corresponding foreign exchange loss, taking
into account our derivatives transactions, that would have resulted as a December 31, 2009 from a hypothetical, instantaneous 10% depreciation of all of our operating currencies against the U.S. dollar, would have been approximately
Ps. 4,061 million. Such depreciation would have also resulted in additional interest expense of approximately Ps. 287 million per annum, reflecting the increased costs of servicing foreign currency indebtedness.



120



---

##### Table of Contents

A hypothetical, immediate increase of 100 basis points in the interest rates applicable to
our floating rate financial liabilities at December 31, 2009 would have resulted in additional interest expense of approximately Ps. 272 million per year, assuming no change in the principal amount of such indebtedness.

The above sensitivity analyses are based on the assumption of unfavorable movements in exchange or interest rates applicable to each
homogeneous category of financial assets and liabilities. A homogeneous category is defined according to the currency in which financial assets and liabilities are denominated and assumes the same exchange rate or interest rate movement with each
homogeneous category. As a result, exchange rate risk and interest rate risk sensitivity analysis may overstate the impact of exchange rate or interest rate fluctuations for such financial instruments, as consistently unfavorable movements of all
exchange rates or interest rates are unlikely.

|Item 12D. | American Depositary Shares
|--------- | --------------------------

The Bank of New York Mellon, or the Depositary, serves as the depositary for our ADSs. ADS holders are required to pay various fees to the
Depositary, and the Depositary may refuse to provide any service for which a fee is assessed until the applicable fee has been paid.

ADS holders are required to pay the Depositary amounts in respect of expenses incurred by the Depositary or its agents on behalf of ADS
holders, including expenses arising from (i) taxes or other governmental charges, (ii) registration fees payable to us that may be applicable to the transfer of shares upon deposits to or withdrawals from the ADS program, (iii) cable,
telex, and facsimile transmission, (iv) conversion of foreign currency into U.S. dollars, or (v) servicing of the ADSs or the shares underlying ADSs. The Depositary may decide in its sole discretion to seek payment by either billing
holders or by deducting the fee from one or more cash dividends or other cash distributions.

ADS holders are also required to
pay additional fees for certain services provided by the Depositary, as set forth in the table below.

|Item 15. | Controls and Procedures
|-------- | -----------------------

(a) Disclosure controls and procedures.We carried out an evaluation under the supervision and with the
participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of December 31, 2009. There are inherent
limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and
procedures can only provide reasonable assurance of achieving their control objectives. Based upon our evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective to
provide reasonable assurance that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the applicable rules and
forms, and that it is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

(b) Managements annual report on internal controls over financial reporting.Our management is
responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934, as amended. Under the supervision and with the
participation of our management, including our Board of Directors, Chief Executive Officer, Chief Financial Officer and other personnel, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the
framework in Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of
financial reporting and the preparation of financial statements for external purposes in accordance with Mexican Financial Reporting Standards, including the reconciliation to U.S. GAAP in accordance with Item 18 of Form 20-F. Our internal
control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets; (ii) provide
reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with Mexican FRS, and that our receipts and expenditures are being made only in accordance with authorizations of our
management and directors; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of our assets that could have a material effect on our financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections
of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Based on our evaluation under the framework in Internal ControlIntegrated Framework, our management concluded that our internal
control over financial reporting was effective as of December 31, 2009.

Mancera, S.C., a member practice of
Ernst & Young Global, an independent registered public accounting firm, our independent auditor, issued an attestation report on our internal control over financial reporting on April 1, 2010.

S.A.B. de C.V. and subsidiaries management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal
control over financial reporting included in the accompanying Managements Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the companys internal control over financial reporting
based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board
(United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an
understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other
procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A companys internal control over financial reporting is a process designed to provide reasonable assurance regarding the
reliability of financial reporting and the preparation of financial statements for external purposes in accordance with Mexican Financial Reporting Standards, including the reconciliation to U.S. GAAP in accordance with Item 18 of Form 20-F. A
companys internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the
assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with Mexican Financial Reporting Standards, including the reconciliation to U.S.
GAAP in accordance with Item 18 of Form 20-F, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance
regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the companys assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections
of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, América Móvil, S.A.B. de C.V. and subsidiaries maintained, in all material respects, effective internal
control over financial reporting as of December 31, 2009, based on the COSO criteria.

We have also audited, in
accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of América Móvil, S.A.B. de C.V. and subsidiaries as of December 31, 2008 and 2009 and the related
consolidated statements of income and changes in shareholders equity for each of the three years in the period ended December 31, 2009 and the consolidated statement of changes in financial position for the year ended December 31,
2007, the consolidated statements of cash flows for each of the two years in the period ended December 31, 2009, and our report dated April 1, 2010, expressed an unqualified opinion thereon.

|Item 16F. | Change in Registrants Certifying Accountant
|--------- | --------------------------------------------

On and effective November 10, 2009, BDO Seidman, LLP (BDO) was dismissed as TracFones independent auditors after
auditing TracFones financial statements for each of the five years in the period ended December 31, 2008. On November 10, 2009, concurrent with BDOs dismissal as TracFones independent auditors, our Audit and Corporate
Practices Committee appointed Mancera, S.C., a member practice of Ernst & Young Global, (Mancera) as TracFones independent auditor. Mancera has served as América Móvils independent auditor since 2000.
The decision to dismiss BDO and engage Mancera as TracFones independent auditors was approved by our Audit and Corporate Practices Committee.

Neither BDOs reports on TracFones financial statements for the year ended December 31, 2007 or December 31, 2008
nor Manceras reports on our financial statements for such years, for which they relied on such BDO reports, contained any adverse opinion or disclaimer of opinion, or qualification or modification as to uncertainty, audit scope, or accounting
principles.

During the fiscal years ended December 31, 2007 and December 31, 2008 and the interim period from
January 1, 2009 to November 10, 2009, there were no disagreements with BDO on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure that if not resolved to the satisfaction of BDO would
have caused BDO to make references to the subject matter of the disagreements in connection with any report.

|--------- | ---------------------

Our corporate governance practices are governed by our bylaws, the Mexican Securities Market Law and the regulations issued by the CNBV.
We also comply with the Mexican Code of Best Corporate Practices (Código de Mejores Prácticas Corporativas), which was created in January 2001 by a group of Mexican business leaders and was endorsed by the CNBV and the Mexican
Stock Exchange.

|Director Independence.Majority of board of directors must be independent. Controlled companies, which would include our
company if we were a U.S. issuer, are exempt from this requirement. A controlled company is one in which more than 50% of the voting power is held by an individual, group or another company, rather than the public. §303A.01 |  | Director Independence.Majority of board of directors must be independent and directors deemed independent must be
identified in a listed companys proxy statement (or annual report on Form 10-K or 20-F if the issuer does not file a proxy statement). Controlled companies, which would include our company if we were a U.S. issuer, are exempt from
this requirement. A controlled company is one in which more than 50% of the voting power is held by an individual, group or another company, rather than the public. Rules 5605(b)(1), 5615(c)(1) & (c)(2). |  | Director Independence.Pursuant to the Mexican Securities Market Law, our shareholders are required to appoint a board of
directors of no more than 21 members, 25% of whom must be independent. Certain persons are per se non-independent, including insiders, control persons, major suppliers and any relatives of such persons. In accordance with the Mexican
Securities Market Law, our shareholders meeting is required to make a determination as to the independence of our directors, though such determination may be challenged by the CNBV. There is no exemption from the independence requirement for
controlled companies.

|ExecutiveSessions.Non-management directors must meet regularly in executive sessions without management. Independent directors
should meet alone in an executive session at least once a year. §303A.03                                                                                                                                                   |  | Executive Sessions.Independent directors must meet regularly in executive sessions at which only independent directors are present.

|Nominating/Corporate Governance Committee.Nominating/corporate governance committee of independent directors is required. The
committee must have a charter specifying the purpose, duties and evaluation procedures of the committee. Controlled companies are exempt from these requirements. §303A.04                                                |  | Nominating Committee.Director nominees must be selected, or recommended for the boards selection, either by a nominating
committee comprised solely of independent directors or by a majority of independent directors. Each listed company also must certify that it has adopted a formal charter or board resolution addressing the                                                                                                                                                                                                                                  |  | Nominating Committee.    We currently do not have a nominating committee or a corporate governance
committee. We are not required to have a nominating committee. However, Mexican law requires us to have one or more committees that oversee certain corporate practices, including appointment of directors and executives. Under the Mexican Securities
Market Law, committees

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Shareholders of

América Móvil, S.A.B. de C.V.

We have audited the accompanying consolidated balance sheets of América Móvil, S.A.B. de C.V. and subsidiaries as of
December 31, 2008 and 2009 and the related consolidated statements of income and changes in shareholders equity for each of the three years in the period ended December 31, 2009 and the consolidated statement of changes in financial
position for the year ended December 31, 2007 and the consolidated statements of cash flows for each of the two years in the period ended December 31, 2009. These financial statements are the responsibility of the Companys
management. Our responsibility is to express an opinion on these financial statements based on our audits. We did not audit the financial statements of TracFone Wireless, Inc., a consolidated subsidiary, whose assets accounted for approximately 1%
of total consolidated assets at December 31, 2008 and approximately 5% of total consolidated operating revenues for each of the two years in the period ended December 31, 2008. Those financial statements were audited by other auditors
whose report has been furnished to us, and our opinion, insofar as it relates to the amounts included for TracFone Wireless, Inc., is based solely on the report of the other auditors.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those
standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation (including the Companys
conversion of the financial statements of TracFone Wireless, Inc. to Mexican Financial Reporting Standards). We believe that our audits and the report of other auditors provide a reasonable basis for our opinion.

In our opinion, based on our audits and the report of other auditors, the financial statements referred to above present fairly, in all
material respects, the consolidated financial position of América Móvil, S.A.B. de C.V. and subsidiaries as of December 31, 2008 and 2009, and the consolidated results of their operations for each of the three years in the period
ended December 31, 2009, and the consolidated changes in their financial position for the year ended December 31, 2007, and their consolidated cash flows for each of the two years in the period ended December 31, 2009, in conformity
with Mexican Financial Reporting Standards, which differ in certain respects from accounting principles generally accepted in the United States (see Note 21 to the consolidated financial statements).

As mentioned in Note 2 a), f), s) and z.1) to the accompanying consolidated financial statements, as of January 1, 2008, the Company
adopted the new Mexican Financial Reporting Standards B-10, Effects of Inflation, B-15, Translation of Foreign Currencies,D-4, Taxes on Profits and B-2, Statements of Cash Flows, with the effects described therein.

Report of Independent Registered Certified Public Accounting Firm

Board of Directors and Stockholders

TracFone Wireless, Inc.

Miami, Florida

We have audited the accompanying balance sheet of TracFone Wireless, Inc. as of December 31, 2008 and the related
statements of income, changes in stockholders equity, and cash flows for each of the two years in the period ended December 31, 2008. These financial statements are the responsibility of the Companys management. Our responsibility
is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the
standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. Our
audits include consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the
Companys internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of TracFone
Wireless, Inc. at December 31, 2008, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2008 in conformity with accounting principles generally accepted in the United States of
America.

AMÉRICA MÓVIL, S.A.B. DE C.V. AND SUBSIDIARIES

Notes to Consolidated Financial Statements

(In thousands of Mexican pesos,

and thousands of U.S. dollars, except when indicated otherwise)



|1. | Description of Business
|-- | -----------------------

América Móvil, S.A.B. de C.V. and subsidiaries (collectively, the Company or América
Móvil) provides wireless and fixed communications services in Latin America and in the Caribbean. América Móvil obtains its revenues primarily from telecommunications services, including the sale of airtime (including
interconnection under the calling party pays program), monthly rent, long-distance charges, and other services (including roaming, value added services and other service charges), as well as the proceeds from the sale of cellular phones and
accessories.

América Móvil has authorization, licenses, permits and concessions (hereinafter collectively
referred to as licenses) to build, install, operate and use both public and private telecommunications networks and provide telecommunication services (mostly mobile and fixed-line telephony) in the countries in which the Company has
presence (except for in the U.S.). These licenses will expire at various times from 2012 through 2046.

Such licenses require
the payment to the respective governments of a share in sales determined as a percentage of revenues from services under concession. The percentage is set as either a fixed rate or in some cases based on the size of the infrastructure in operation
(except for Guatemala and El Salvador).

|2. | Summary of Significant Accounting Policies and Practices
|-- | --------------------------------------------------------

The consolidated financial statements have been prepared in conformity with Mexican Financial Reporting Standards, issued by the Mexican
Financial Reporting Standards Research and Development Board (Consejo Mexicano para la Investigación y Desarrollo de Normas de Información Financiera, A.C. or CINIF). The principal accounting policies and practices followed by
the Company in the preparation of these consolidated financial statements are described below:

a) Consolidation and basis of translation
of financial statements of foreign subsidiaries

i) Consolidation and equity method

The consolidated financial statements include the accounts of América Móvil, S.A.B. de C.V. and those of its subsidiaries.
The financial statements of the subsidiaries have been prepared for the same accounting period and follow the same accounting principles as those of the Company. All the companies operate in the telecommunications sector or provide services to
companies operating in this sector.

All intercompany balances and transactions have been eliminated in the consolidated
financial statements. Non-controlling interest refers to certain subsidiaries in which the Company does not hold 100% of the shares.

Equity investments in affiliated companies over which the Company exercises significant influence are accounted for using the equity
method, which basically consists of recognizing América Móvils proportional share in the net income or loss and the shareholders equity of the investee.

The results of operations of the subsidiaries and affiliates were included in the Companys consolidated financial statements as of
the month following their acquisition.

ii) Basis of translation of financial statements of foreign subsidiaries

The financial statements of foreign subsidiaries and affiliates, which in the aggregate account for approximately 59%, 61% and 64% of the
Companys total operating revenues for 2007, 2008 and 2009, respectively, and approximately 75% and 85% of the Companys total assets at December 31, 2008 and 2009, are either consolidated or accounted for based on the equity method,
as the case may be, after their financial statements have first been adjusted to conform to Mexican Financial Reporting Standards in the corresponding functional currency and have then been translated to the reporting currency.

The financial statements of the subsidiaries and affiliates located abroad were translated into Mexican pesos, as follows:

Effective January 1, 2008, the Company adopted the MFRS B-15, Foreign Currency Translation. Consequently, the financial
statements as reported by the foreign subsidiaries and affiliates are converted to conform to Mexican Financial Reporting Standards in the local currency, and subsequently translated into the reporting currency. Since none of the Companys
subsidiaries or affiliates operates in an inflationary environment, except for Argentina and Nicaragua; and the local currencies are its functional currencies, the financial statements prepared under Mexican Financial Reporting Standards reported by
the subsidiaries and affiliates abroad in the local currency are translated as follows:



| | i) | all monetary assets and liabilities are translated at the prevailing exchange rate at year-end;
| | -- | -----------------------------------------------------------------------------------------------



| | ii) | all non-monetary assets and liabilities are translated at the prevailing exchange rate at year-end;
| | --- | ---------------------------------------------------------------------------------------------------

| | iii) | shareholders equity accounts are translated at the prevailing exchange rate at the time capital contributions were made and earnings were generated;
| | ---- | -----------------------------------------------------------------------------------------------------------------------------------------------------



| | iv) | revenues, costs and expenses are translated using the average exchange rate;
| | --- | ----------------------------------------------------------------------------



| | v) | translation differences are recorded in shareholders equity in the line item Effect of translation of foreign entities under Accumulated other comprehensive
income items; and
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | vi) | the statement of cash flows was translated using the weighted average exchange rate and the difference is presented in the statement of cash flows under the caption
Adjustment to cash flow for exchange rate differences.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Through December 31, 2007, the
financial statements as reported by the foreign subsidiaries were converted to conform to Mexican Financial Reporting Standards in the local currency, and subsequently restated to constant monetary values based on the inflation rate of the country
in which the subsidiary operates. Under this method, all assets and liabilities were translated at the prevailing exchange rate at year-end; shareholders equity accounts were translated at the prevailing exchange rate at the time capital
contributions were made and earnings were generated; income statement amounts were translated at the prevailing exchange rate at the end of the year being reported on; exchange rate variances and effect of intercompany monetary items were recorded
in the consolidated statements of income; and translation differences were recorded in shareholders equity in the line item Effect of translation of foreign entities under Accumulated other comprehensive income items. For the years
ended December 31, 2007, 2008 and 2009, the gain on translation was Ps. 10,001,762, Ps. 12,044,547 and Ps. 13,236,787, respectively

The statement of changes in financial position for the year ended December 31, 2007 was prepared based on the financial statements
expressed in constant Mexican pesos. The source and application of resources represent the differences between beginning and ending financial statement balances in constant Mexican pesos. Monetary and foreign exchange gains and losses are not
considered as items not requiring the use of resources in the statement of changes in financial position.

b) Revenue
recognition

Revenues are recognized at the time services are provided and when the probability of their collection is
reasonably assured. Mobile telecommunications services are provided either under prepaid (calling cards), or post payment (agreement) plans, or both. In all cases, airtime revenues are recognized as a customer uses the airtime or when the card
expires in the case of prepayments or for unused airtime.

Monthly basic rent under post-paid plans is billed in arrears based
on the plan and package rates approved and correspond to services rendered, except in Mexico and Colombia, where basic monthly rent is billed one month in advance. Revenues are recognized at the time services are provided. Billed revenues for the
service not yet rendered are recognized as deferred revenues.

Revenues from interconnections services, which consist of calls
of other carriers that enter the Companys cellular network (incoming interconnections services), are recognized at the time the service is provided. Such services are billed based on rates previously agreed with the other carriers.

Long-distance charges refer to airtime used in receiving from or making calls to regions or coverage areas outside of the area where the
customer service is activated. The related revenues are recognized at the time the service is provided.

Roaming charges
represent airtime charged to customers for making or receiving calls outside their coverage areas or abroad. The related revenues are recognized at the time the service is provided based on the rates agreed upon by our subsidiaries with other
domestic and international carriers.

##### Table of Contents

Value added services and other services include voice services and data transmission
services (such as two-way and written messages, call information, ring tones, emergency services, among others). Revenues from such services are recognized at the time they are provided or when the services are downloaded.

Sales of handsets and accessories, which for the most part are made to authorized distributors, are recorded as revenue when a) the
products are delivered and accepted by the distributor, b) distributors do not have a right to return the product and c) probability of collection is reasonably assured.

Discounts granted on the sale of cellular equipment to wholesalers, retailers and department store chains are recognized as reductions in
the price of the phone.

Telgua, ENITEL, CTE, Codetel and Puerto Ricos revenues from telephone line installation fees
(net of related costs) are deferred and recognized over the estimated average life of the customer.

The Company usually does
not charge activation fees for its mobile telephony services; however, in certain regions, depending on the particular market, certain activation fees are charged. The Company recognizes revenues from these fees when billed. These revenues are not
deferred because they are not significant to the Companys financial statements.

c) Cost of cellular telephone equipment

The cost related to cellular telephone equipment is recognized in the statements of income at the time the corresponding
income is recognized. Shipping and handling costs for wireless handsets sold to distributors are classified as costs of sales.

d) Network
interconnection costs, long distance costs and rent paid for use of infrastructure

These costs represent the costs of
outgoing calls from the Companys cellular networks to other carriers network, the costs of link-ups between fixed and cellular networks, long-distance charges and rent paid for use of infrastructure (links, ports and measured usage), as
well as the message exchange between operators, all of which are recognized as costs at the time the service is received.

e) Commissions
paid to distributors

Commissions paid with respect to the activation of postpaid customers are recognized as expenses at
the time the new customer is activated in the system and may begin using the Companys cellular network.

Loyalty and
sales volumes commissions are accrued on a monthly basis based on statistical information regarding customer retention, sales volume and the number of acquired customers by each distributor. Loyalty commissions are paid to distributors for customers
that remain for a specified period of time, and sales volume commissions are paid at the time the distributor reaches certain ranges of activated customers.

f) Recognition of the effects of inflation

Mexican FRS B-10,Effects of Inflation, which became effective on January 1, 2008, requires that once it has been confirmed
that the economic environment in which the Company operates has changed from inflationary to non-inflationary as of the beginning of the period, the Company should cease to recognize the effects of inflation. The Company currently operates in a
non-inflationary economic environment because the cumulative inflation rate in Mexico over the past three years was 15.01% (11.56% in 2008).

The financial statements for the years ended December 2009 and 2008 are expressed in nominal pesos, except for those non-monetary items
that include inflation effects at December 31, 2007 and current pesos due to the changes realized subsequent to that date.

##### Table of Contents

Capital stock and retained earnings were restated for inflation through December 31,
2007 based on the Mexican National Consumer Price Index (NCPI).

Through December 31, 2007, the deficit from restatement
of shareholders equity consists of the accumulated monetary position gain at the time the provisions of Bulletin B-10 were first applied, which was Ps. 19,327, and of the result from holding non-monetary assets, which represents the difference
between restatement by the specific indexation method and restatement based on the NCPI. At December 31, 2007, the Ps. 14,562,294 balance of this item is included in shareholders equity under the caption Accumulated other comprehensive
income items. In conformity with Mexican FRS B-10, since it was unpractical to identify the result from holding non-monetary assets with the items giving rise to them, the cumulative result from holding non-monetary assets, together with the
initial effect from the adoption of Bulletin B-10 net of Ps. 771,928 of deferred taxes, was reclassified to retained earnings.

The net monetary position gain shown in the 2007 income statement represents the effect of inflation on monetary assets and liabilities
and is included as part of the caption Comprehensive result of financing.

g) Cash and cash equivalents

Cash and cash equivalents consist basically of bank deposits and highly liquid investments with original maturities of less than 90 days.
Such investments are stated at acquisition cost plus accrued interest, which is similar to their market value.

h) Investments in
marketable securities

Investments in marketable securities have been classified either as trading marketable securities or
available-for-sale marketable securities. All investments are represented by equity securities and are recognized at market value. Changes in the fair value of instruments classified as trading securities are recognized in results of operations.
Changes in the market value of instruments classified as available-for-sale are included in shareholders equity until they are sold.

Should there be objective and lasting evidence of impairment in the value of either its instruments available-for-sale or held to
maturity, the Company determines the amount of the related loss and recognizes such loss as part of the comprehensive financing income (cost). For the year ended December 31, 2007, since the loss on fair value of securities available-for-sale
was other than temporary, the Company included an impairment loss of Ps. 1,362,900 in the statement of income. For the years ended December 31, 2008 and 2009, there were no impairment losses on marketable securities.

i) Allowance for doubtful accounts

The Company recognizes periodically in its results of operations an allowance for doubtful accounts for its portfolios of postpaid
customers, distributors and network operators (basically for interconnection fees). The allowance is based primarily on past write-off experience and on the aging of accounts receivable balances, as well as managements estimates as to when
dispute proceedings with operators will be resolved.

Collection policies and procedures vary by the type of credit extended,
the payment history of customers and the age of the unpaid calls.

The risk of uncollectibility from intercompany receivables
is evaluated annually based on an examination of each related partys financial situation and the markets in which they operate.

j)
Inventories

Cellular equipment inventories are initially recognized at historical acquisition cost, and valued using the
average-cost method.

k) Business acquisitions and goodwill

Business and entity acquisitions are recorded using the purchase method and until 2008, the acquisition of non-controlling interest is
considered a transaction between entities under common control and any difference between the purchase price and the book value of net assets acquired is recognized as an equity transaction. Effective January 1, 2009, in conformity with Mexican
FRS B-7, Business Combinations, if the acquisition of non-controlling interest is made at fair value, the purchase price is also recognized based on the fair value of the net assets acquired.

Goodwill represents the difference between the acquisition price and the fair value of the net assets acquired at acquisition date.

Goodwill is recorded initially at acquisition cost and up to December 31, 2007 was restated using adjustment factors
derived from the NCPI. Goodwill is no longer amortized, but rather is subject to annual impairment valuations at the end of each year, or during the year if there are indications of impairment.

Impairment losses are recognized when the carrying amount of goodwill exceeds its recovery value. The Company determines the recovery
value of goodwill based on its perpetuity value, which is computed by dividing the average excess in the value in use of the cash generating unit where the intangible is identified, by the average of the appropriate discount rates used in the
projection of the present value of cash flows from the cash generating unit.

For the year ended December 31, 2007, there
were no goodwill impairment losses recognized by the Company.

For the year ended December 31, 2008, the Company
recognized a loss of Ps. 527,770 from impairment in the value of goodwill. Such loss was included in the statement of income as part of the caption Other expenses, net. This impairment was originated by the subsidiary in Honduras.

For the year ended December 31, 2009, there was no impairment losses recorded.

l) Telephone plant, property and equipment

Effective January 1, 2008, purchases of plant, property and equipment are recorded at acquisition cost. Through December 31,
2007, plant, property and equipment and construction in progress acquired abroad were restated based on the rate of inflation of the respective country of origin and the prevailing exchange rate at the balance sheet date (specific indexation
factors), while plant, property and equipment of domestic origin were restated based on the NCPI.

Depreciation is computed on
restated values using the straight-line method based on the estimated useful lives of the related assets, starting the month after the assets are put to use.

Annual depreciation rates are as follows:



|                                                                    |  |           
|------------------------------------------------------------------- |  | ----------
|Telephone plant                                                     |  | 10% to 33%
|System-performance monitoring equipment included in telephone plant |  | 33%       
|Buildings                                                           |  | 3%        
|Other assets                                                        |  | 10% to 25%

As of
January 1, 2007, the Company adopted the provisions of Mexican FRS D-6, Capitalization of the Comprehensive Cost of Financing, establishing that entities must capitalize comprehensive financing cost (CFC), which corresponds to net
interest expense, exchange differences, the monetary position result and other financial costs related to the acquisition of the telephone plant.

##### Table of Contents

The comprehensive cost of financing incurred during the building and installation period is
capitalized and was restated up to December 31, 2007 using the NCPI. The net effect of the capitalization of such cost in 2007 was an increase in net income in 2007 of Ps. 1,158,576 (Ps. 834,175 net of taxes), Ps. 7,053,951 (Ps. 5,289,244 net
of taxes) in 2008 and Ps. 1,626,731 (Ps.1,127,202 net of taxes) in 2009.

The value of plant, property and equipment is
reviewed on an annual basis to verify whether there are indicators of impairment. When the recovery value of an asset, which is the greater of its selling price and value in use (the present value of future cash flows), is lower than its net
carrying value, the difference is recognized as an impairment loss.

During the year ended December 31, 2007, the Company
wrote-off the remaining carrying value of its telephone plant that utilizes TDMA technology in Colombia and Ecuador due to its obsolescence. This write-down was made after considering both technological obsolescence of TDMA in those specific
geographies and also other economic and operational considerations. The write-off amounted to Ps. 2,735,000 and has been included as a component of the caption Other expenses, net in the accompanying 2007 consolidated statement of income. The
Company also began to accelerate TDMA depreciation in Brazil (see Note 7).

For the year ended December 31, 2008, the
Company recognized a loss of Ps. 113,422 from impairment in the value of the telephone plant recorded in the consolidated balance sheet. Such loss was included in the statement of operations as part of the caption Other expenses, net.

For the year ended December 31, 2009, there were no impairment losses recognized.

m) Licenses and trademarks

Effective January 1, 2008, the Company records licenses at acquisition cost. Through December 31, 2007, licenses were restated
based on the rate of inflation of each country.

Licenses to operate wireless telecommunications networks are accounted for at
cost or at fair value at the business acquisition date. Licenses are being amortized using the straight-line method over periods ranging from 15 to 40 years, which correspond to the usage period of each license.

Trademarks are recorded at their values in use at the date acquired, as determined by independent appraisers, and are amortized using the
straight-line method over a ten-year period.

The carrying values of intangible assets with definite useful lives are reviewed
annually and whenever there are indications of impairment in such values. When the recovery value of an asset, which is the greater of its selling price and value in use (the present value of future cash flows), is lower than its net carrying
amount, the difference is recognized as an impairment loss.

Intangible assets with indefinite useful lives, including those
that are not yet available for use and intangibles with definite useful lives whose amortization period exceeds 20 years from the date they were available for use, are tested for impairment at the end of each year.

At December 31, 2008, the Company recognized a loss of Ps. 98,661 from impairment in the value of licenses recorded in the
consolidated balance sheet and recognized the loss in the statement of income as part of the caption Other expenses, net. This impairment was originated by the subsidiary in Honduras.

For the years ended December 31, 2007 and 2009, there were no impairment losses recognized.

n) Leases

 Sale and leaseback

The
Company entered into sales and leaseback agreements that meet the conditions for consideration as financial leases. Such agreements give rise to losses derived from the difference between the assets sale price and its value in books that
result in the recognition of deferred charges that are being amortized based on the remaining useful life of the related assets at the time of sale.

 Operating leases

Rent
paid under operating leases is recognized in results of operations as it accrues.

 Financial leases

Lease arrangements are recognized as capital leases if (i) the ownership of the leased asset is transferred to the lessee upon
termination of the lease; (ii) the agreement includes an option to purchase the asset at a reduced price; (iii) the term of the lease is substantially the same as the remaining useful life of the leased asset; or (iv) the present
value of minimum lease payments is substantially the same as the market value of the leased asset, net of any benefit or scrap value.

o)
Transactions in foreign currencies

Transactions in foreign currency are recorded at the prevailing exchange rate at the
time of the related transactions. Foreign currency denominated assets and liabilities are translated at the prevailing exchange rate at the balance sheet date. Exchange differences determined from such date to the time foreign currency denominated
assets and liabilities are settled or translated at the balance sheet date are charged or credited to operations, except for those arising on foreign currency denominated loans for the construction of fixed assets, as such costs are capitalized as
comprehensive financing costs during the construction stage.

See Note 14 for the Companys consolidated foreign currency
position at the end of each year and the exchange rates used to translate foreign currency denominated balances.

p) Accounts payable and
accrued liabilities

Liabilities are recognized whenever (i) the Company has current obligations (legal or assumed)
resulting from past events, (ii) when it is probable the obligation will give rise to a future cash disbursement for its settlement and (iii) the amount of the obligation can be reasonably estimated.

When the effect of the time value of money is material, the amount of the reserve is determined as the present value of the expected
disbursements to settle the obligation. The discount rate applied is determined on a pre-tax basis and reflects current market conditions at the balance sheet date and, where appropriate, the risks specific to the liability. Where discounting is
used, an increase in the reserve is recognized as financial expense.

Reserves for contingent liabilities are recognized only
when it is probable they will give rise to a future cash disbursement for their settlement. Also, contingencies are only recognized when they will generate a loss.

q) Employee benefits

In
Radiomóvil Dipsa, S.A. de C.V. and in Telecomunicaciones de Puerto Rico, S.A., the Company has established defined benefit pension plans. These plans require the valuation and recognition of the accumulated effects of retirement and
post-retirement labor obligations. Such effects are determined based on actuarial studies using the projected unit-credit method.

##### Table of Contents

In Consorcio Ecuatoriano de Telecomunicaciones S.A. (subsidiary in Ecuador), the Company has
an individual capitalization pension plan, whereby it purchases a single-premium deferred annuity from an insurance company, for which the Company only makes a yearly premium payment. In accordance with Mexican FRS D-3, this plan falls under the
category of a defined contribution plan and thus, only the net period cost of the plan must be disclosed.

Seniority premiums
are paid to personnel of the Mexican subsidiaries as required by Mexican labor law. Also under Mexican labor law, the Company is liable for certain benefits accruing to workers who leave or are dismissed in certain circumstances.

The Company recognizes annually the cost for pension benefits, seniority premiums and termination payments based on independent actuarial
computations applying the projected unit-credit method, using real rates (financial hypotheses net of inflation). The latest actuarial computation date was prepared as of December 31, 2009.

In conformity with the labor laws of the rest of the countries in which the Company operates, there are no statutory defined benefit
plans or compulsory defined contribution structures for companies. However, the foreign subsidiaries make contributions to national pension, social security and severance plans in accordance with the percentages and rates established by the
applicable laws.

Such contributions are made to bodies designated by each government and are recorded in results of
operations as direct labor benefits as they are incurred or when the contribution is made.

Effective January 1, 2008,
the Company adopted Mexican FRS D-3, Employee Benefits, which replaced Mexican accounting Bulletin D-3, Labor Obligations. The adoption of Mexican FRS D-3 did not have an effect on the Companys financial position or results of
operation.

Actuarial gains and losses are amortized over the estimated average remaining working lifetime of Company
employees, which is 20 years.

The Company recognizes a reserve for the costs of paid absences, such as vacation time, based
on the accrual method.

r) Employee profit sharing

Current-year employee profit sharing is presented under the caption Commercial, administrative and general expenses in the
income statement.

Beginning January 1, 2008, in connection with the adoption of Mexican FRS D-3, Employee Benefits, the
Company recognized deferred employee profit sharing using the asset and liability method. Under this method, deferred profit sharing is computed by applying the 10% rate (Mexico and Peru) and 15% (Ecuador) to all differences between the book and tax
values of all assets and liabilities. At December 31, 2008 and 2009, the amounts were not significant.

Through
December 31, 2007, deferred employee profit sharing was determined only on temporary differences in the reconciliation of current year net income to taxable income for employee profit sharing purposes, provided there was no indication that the
related liability or asset would not be realized in the future.

s) Taxes on profits

Current year taxes on profits are presented as a short-term liability, net of prepayments made during the year.



F-17



---

##### Table of Contents

The Company determines deferred taxes on profits based on the asset and liability method
established in Mexican FRS D-4, Taxes on Profits. Under this method, deferred taxes on profits are recognized on all differences between the financial reporting and tax bases of assets and liabilities, including effects of translation,
applying the enacted income tax rate or the flat-rate business tax rate (FRBT, applicable only in Mexico), as the case may be, effective as of the balance sheet date, or the enacted rate at the balance sheet date that will be in effect
when the temporary differences giving rise to deferred tax assets and liabilities are expected to be recovered or settled.

The Company periodically evaluates the possibility of recovering deferred tax assets and if necessary, creates a valuation allowance for
those assets that are not more likely than not to be realized.

Effective January 1, 2008, asset tax paid in excess of
income tax in Mexico is treated as a tax credit, while through December 31, 2007, asset tax was recorded as part of deferred income tax. In both cases, an evaluation of its future realization is performed.

As a result of the adoption of Mexican FRS D-4 in 2008, the Company recognized deferred taxes in the amount of Ps. 2,825,486 for the
effects of translation of foreign companies at December 31, 2008. Such amount is presented in a shareholders equity item as part of the caption Accumulated other comprehensive income items.

t) Advertising

Advertising costs are expensed as incurred. For the years ended December 31, 2007, 2008 and 2009, advertising expenses aggregated to
Ps. 7,175,663, Ps. 8,520,506 and Ps. 9,932,119, respectively.

u) Comprehensive income

Comprehensive income consists of the net income for the year plus the following items that are reflected directly in shareholders
equity: the effect of translation of financial statements of foreign entities, the effect of current year deferred taxes, and other items different from net income.

At December 31, 2008 and 2009, an analysis of accumulated other comprehensive income items other than net income is as follows:



|                                          |  |                |   |  |                |  
|----------------------------------------- |  | -------------- | - |  | -------------- | -

|                                          |  |                |   |  |                |

|                                          |  |                |   |  |                |  

v) Earnings per share

The Company determined earnings per share by dividing net majority income by the weighted average number of shares issued and outstanding
during the period. In determining the weighted average number of shares issued and outstanding, shares acquired by repurchases by the Company have been excluded.

w) Use of estimates

The
preparation of financial statements in conformity with Mexican Financial Reporting Standards requires the use of estimates and assumptions. Actual results could differ from these estimates.

x) Concentration of risk

The Companys principal financial instruments consist of bank loans, derivative financial instruments, financial leases and accounts
payable. The Company has other financial assets, such as accounts receivable, prepaid expenses and short-term deposits, that are directly related to its business.

##### Table of Contents

The main risks associated with the Companys financial instruments are cash flow risk,
liquidity risk, market risk and credit risk. The Company performs sensitivity analyses to measure potential losses in its operating results based on a theoretical increase of 100 basis points in interest rates and a 10% change in exchange rates. The
Board of Directors approves the risk management policies that are proposed by the Companys management.

Credit risk
represents the potential loss from the failure of counterparties to completely comply with their contractual obligations. The Company is also exposed to market risks related to fluctuations in interest rates and exchange rates. To reduce the risks
related to fluctuations in exchange rates, the Company uses derivative financial instruments.

Financial instruments which
potentially subject the Company to concentrations of credit risk are cash and cash equivalents, trade accounts receivable, and debt and derivative financial instruments. The Companys policy is designed to not restrict its exposure to any one
financial institution; therefore, the Companys financial instruments are maintained in different financial institutions located in different geographical areas.

The credit risk in accounts receivable is diversified because the Company has a broad customer base that is geographically dispersed. The
Company continuously evaluates the credit conditions of its customers and does not require collateral to guarantee collection of its accounts receivable. In the event the collection of accounts receivable deteriorates significantly, the
Companys results of operations could be adversely affected.

A portion of excess cash is invested in time deposits in
financial institutions with strong credit ratings.

The Company operates internationally and is therefore exposed to market
risks related to fluctuations in exchange rates.

The Company relies on several key suppliers. Approximately 21%, 32% and 31%
of the Companys aggregate interconnection expenditures for the years ended December 31, 2007, 2008 and 2009, respectively, represented services rendered by one supplier; approximately 75%, 70% and 66%, respectively, of the aggregate cost
of cellular telephone equipment for such periods represented purchases from three suppliers; and approximately 58%, 54% and 39%, respectively, of telephone plant purchases were made from two suppliers. If any of these suppliers fails to provide the
Company with services or equipment on a timely and cost effective basis, the Companys business and results of operations could be adversely affected.

y) Derivative financial instruments

The Company is exposed to interest rate and foreign currency risks, which are mitigated through a controlled risk management program that
includes the use of derivative financial instruments. In order to reduce the risks due to exchange rate fluctuations, the Company utilizes swaps, cross currency swaps and forwards to fix exchange rates to the liabilities being hedged; however, since
the Company has not formally documented the hedging relationship, it does not apply hedge accounting rules to its derivative financial instruments.

Derivative financial instruments are recognized in the balance sheet at their fair values, which are obtained from the financial
institutions with which the Company has entered into the related agreements. Changes in the fair value of derivatives are recognized in results of operations.

z) Statement of income presentation

Costs and expenses in the Companys income statement are presented on a combined basis between their nature and function, which
allows operating income levels to be shown, since such classification allows the captions to be compared with other companies in the Telecommunications industry.

The Operating income caption is shown in the statement of income since it is an important indicator used for evaluating the
Companys operating results. Operating income consists of ordinary revenues and operating costs and expenses and thus excludes other income (expenses), net. This presentation is comparable to the one used in the financial statements at and for
the years ended December 31, 2007 and 2008.

##### Table of Contents

z.1) Mexican FRS B-2,Statement of Cash Flows

Mexican FRS B-2 replaced Mexican accounting Bulletin B-12, Statement of Changes in Financial Position. Accordingly, the statement
of cash flows substituted the statement of changes in financial position. The main differences between both statements lie in the fact that the statement of cash flows shows the entitys cash inflows and outflows during the period, while the
statement of changes in financial position shows the changes in the entitys financial structure. Also, the statement of cash flows presents first income before taxes on profits, followed by cash flows from operating activities, then cash flows
from investing activities and finally cash flows from financing activities.

The statements of cash flows for the years ended
December 31, 2008 and 2009 were prepared using the indirect method. The statement of cash flows is not comparable to the statement of changes in financial position that is presented for the year ended December 31, 2007.

z.2) Operating segments

Segment information is prepared based on information used by the Company in its decision-making processes based on the geographical areas
in which América Móvil operates.

z.3) New accounting pronouncements that became effective in 2009

Mexican FRS B-7,Business Combinations

In December 2008, the CINIF issued Mexican FRS B-7, which became effective for fiscal years beginning on or after January 1, 2009.
Mexican FRS B-7 replaced Mexican accounting Bulletin B-7, Business Combinations.

Both Mexican FRS B-7 and Mexican
accounting Bulletin B-7 require the application of the purchase method for the recognition of business combinations. However, unlike Mexican accounting Bulletin B-7, this standard: (i) requires that the total net assets acquired and
consideration paid to be valued at fair value; and (ii) requires that all of the costs incurred in a business combination be recognized in the operating results of the acquiring entity. As a result of this change, it was clarified that goodwill
must be determined for both the controlling (majority) interest and the non-controlling (minority) interest, the latter of which must be valued at fair value.

In certain cases, this standard allows transactions between entities under common control to be treated as business combinations, unlike
Mexican accounting Bulletin B-7, which requires such transactions, without exception, to be stated at book value. Regarding business combinations carried out in stages, this standard also clarifies that the values recognized in the balance sheet of
the buyer for its investment, net of any depreciation, amortization or impairment adjustments, are to be considered as part of the consideration paid (and not at their fair value), when determining goodwill at the time control is acquired over the
investee.

Finally, Mexican FRS B-7 also clarifies that the recognition of push-down adjustments to the financial statements
of the acquired entity is not applicable in Mexico and provides no transitory guidance in this regard.

The Company did not
have business acquisitions in 2009, and thus the adoption of this standard had no impact on the Companys financial statements

Mexican FRS B-8,Consolidated and Combined Financial Statements

Mexican FRS B-8, which is effective for fiscal years beginning on or after January 1, 2009. Mexican FRS B-8 replaces Mexican
accounting Bulletin B-8, Consolidated and Combined Financial Statements and the Valuation of Long-Term Equity Investments. Mexican FRS B-8 establishes the overall guidelines for preparing and presenting consolidated or combined financial
statements, and transfers the guidance related to accounting for long-term equity investments to Mexican FRS C-7.



F-20



---

##### Table of Contents

The most important amendments, changes or additions to this standard are as follows:

Unlike Mexican accounting Bulletin B-8, Mexican FRS B-8 does not require sub-holding companies to present consolidated
financial statements under certain circumstances. In such cases, the investments in subsidiaries of these intermediary holding companies are accounted for using the equity method.

This standard establishes that to determine the existence of control, the Company must consider any potential voting rights held that
might be exercised or converted, regardless of managements actual intention and financial capacity to exercise such rights.

This standard also includes guidelines for the accounting treatment of special purpose entities and, upon adoption, abolishes the
supplementary application of SIC 12, Consolidation - Special Purpose Entities. Mexican FRS B-8 establishes that specific purpose entities over which the Company exercises control must be consolidated, irrespective of their business purpose or
line of business.

e) This standard establishes that changes in equity interest that do not cause loss of
control must be recognized as transactions between shareholders; therefore, any difference between the book value of the equity investment sold or acquired and the value of the consideration paid must be recognized in shareholders equity.

The adoption of this standard did not have an impact on the Companys consolidated financial statements since there was
no change in control, the Company has no special purpose entities and did not acquire any subsidiaries.

Mexican FRS C-7,Investments in Affiliates and Other Permanent Investments

Mexican FRS C-7 modifies the guidelines for
the accounting recognition of investments in affiliates contained in Mexican accounting Bulletin B-8, Consolidated and Combined Financial Statements and the Valuation of Long-Term Equity Investments. Under the new standard, significant
influence is considered to exist when an entity holds an equity interest of more than 10% in the case of publicly traded entities, and 25% in the case of unlisted entities. This standard establishes that in determining the existence of control, any
potential exercisable or convertible voting rights held must be taken into account. Mexican FRS C-7 establishes the guidelines for determining the existence of significant influence in the case of SPEs and provides a specific procedure for
recognizing the accumulated losses incurred by affiliates.

This standard requires the financial statements of affiliates to
be prepared under the same Mexican FRS as those of the controlling company, which eliminates the possibility of recognizing the equity interest in regulated affiliates using financial statements prepared under the specific accounting standards for
their sectors.

The adoption of this standard did not have an impact on the Companys consolidated financial statements.

Mexican FRS C-8,Intangible Assets

This standard replaces Mexican accounting Bulletin C-8, Intangible Assets, for fiscal years beginning on January 1, 2009.

Unlike Mexican accounting Bulletin C-8, this standard establishes that separability is not the only condition necessary to
determine that an intangible asset is identifiable. Mexican FRS C-8 also provides additional guidance on the accounting recognition of intangible assets acquired through exchange transactions and eliminates the presumption that the useful life of an
intangible asset could not exceed twenty years. Furthermore, the standard adds the requirement of an accelerated amortization period as a condition for impairment and modifies the definition of pre-operating costs.

The adoption of this standard did not have an impact on the Companys consolidated financial statements.

##### Table of Contents

The most important new accounting pronouncements that will become effective in 2010 are as
follows:

Mexican FRS C-1,Cash and Cash Equivalents

Mexican FRS C-1 was issued by the CINIF in November 2009 to replace Mexican accounting Bulletin C-1, Cash, and is effective for
fiscal years beginning on or after January 1, 2010. The principal changes compared to the old Mexican accounting Bulletin C-1 are as follows:

a) Under this standard, cash and cash equivalents are required to be grouped together.

b) Mexican FRS C-1 establishes that restricted cash and cash equivalents must be presented in the cash and cash
equivalents caption in the statement of financial position, rather than separately.

c) This standard
substitutes the term short-term demand investments with the new term liquid demand investments.

d) Mexican FRS C-1 also defines the following terms: acquisition costs, cash equivalents, restricted cash and cash
equivalents, liquid demand investments, net realizable value, nominal value and fair value.

The Company does not believe that
the adoption of this new accounting standard will have a material effect on the valuation of its cash and cash equivalents and that it will only give rise to changes in the names of certain items.

The most important new accounting pronouncements that will become effective in 2011 are as follow:

Mexican FRS B-5,Financial Information by Segment

In November 2009, the CINIF issued Mexican FRS B-5, which is effective for fiscal years beginning on or after January 1, 2011.
Mexican FRS B-5 will replace Mexican accounting Bulletin B-5.

Mexican FRS B-5 establishes the criteria for identifying the
segments to be reported by an entity, as well as the standards for disclosing the financial information of such segments. The standard also contains the requirements applicable to the disclosure of certain information related to the entity as a
whole.

The principal changes compared to Mexican accounting Bulletin B-5 are as follows:

Information to be disclosed - Mexican FRS B-5 is management-focused, since the segment information disclosures it requires refer to the
information used by the entitys most-senior business decision makers. Mexican FRS B-5 also requires the disclosure of information related to entitys products, geographic regions, customers and suppliers.

Business risks - In identifying operating segments, this standard does not require that different areas of the business necessarily be
subject to different risks.

Segments in the pre-operating stage - Under Mexican FRS B-5, the different areas of a business in
its pre-operating stage may be classified as operating segments.

Disclosure of financial results - This standard requires
disclosure of interest income and expense, as well as the other comprehensive financing items.

Disclosure of liabilities -
Mexican FRS B-5 requires disclosure of the liabilities included in the regular information for the operating segment that is habitually used by the entitys most-senior business decision makers.

Mexican FRS B-9,Interim Financial Information

In November 2009, the CINIF issued Mexican FRS B-9, which is effective for fiscal years beginning on or after January 1, 2011.
Mexican FRS B-9 will replace Mexican accounting Bulletin B-9.



F-22



---

##### Table of Contents

Mexican FRS B-9 establishes that interim financial information must contain, as a minimum
for each interim period, the following comparative financial statements:



| |  |  | Condensed statement of financial position
| | - |  | -----------------------------------------



| |  |  | Condensed income statement or statement of activities, as applicable
| | - |  | --------------------------------------------------------------------



| |  |  | Condensed statement of changes in shareholders equity
| | - |  | ------------------------------------------------------



| |  |  | Condensed statement of cash flows
| | - |  | ---------------------------------



| |  |  | Notes to financial statements with select disclosures
| | - |  | -----------------------------------------------------

Mexican FRS B-9 requires the interim financial information at the end of a period to be compared to the information at the closing of the
immediately prior equivalent period (except for the statement of financial position), which makes it necessary to also include a comparison with the statement at the immediately prior annual closing date.

International Financial Reporting Standards Adoption

Beginning with the year ended December 31, 2012, Mexican issuers with securities listed on a Mexican securities exchange will be
required to prepare financial statements in accordance with International Financial Reporting Standards (IFRS), as adopted by the International Accounting Standards Board. Issuers may voluntarily report using IFRS before the change in
the reporting standards becomes mandatory. The Company plans to begin reporting financial statements in IFRS no later than 2012.

Reclassifications

Certain captions shown in the 2007 financial statements as originally issued have been reclassified for
uniformity of presentation with the 2008 and 2009 financial statements

z.5) Convenience translation

U.S. dollar amounts as of December 31, 2009 shown in the financial statements have been included solely for the convenience of the
reader and are translated from Mexican pesos as of December 31, 2009, divided by an exchange rate of Ps. 13.059 per dollar, which is the December 31, 2009 exchange rate. Such translation should not be construed as a representation
that the peso amounts have been or could be converted into U.S. dollars at this or any other rate.



|3. | Investments in Marketable Securities
|-- | ------------------------------------

At December 31, 2008 and 2009, the Company does not have a marketable securities portfolio.

However, at December 31, 2007, the net unrealized loss on for-trading securities was Ps. 2,441. The net realized gain was Ps. 29,604
and Ps. 19,786 for the years ended December 31, 2007 and 2008, respectively. All such valuation results are recognized in results of operations.

##### Table of Contents

As a result of the loss in the market value of the securities of the issuer U.S. Commercial
(USCO), in 2007, the Company recorded an other than temporary loss of Ps. 1,362,900 in its results of operations under the other financing costs, net caption. In December 2007, USCOs shares were transferred to the Carso Foundation (a related
party) as a charitable donation.

d) Given the speed in which important breakthroughs and changes in telecommunications
equipment technology arise, the Company reevaluates periodically the estimated useful life of its telephone plant and adjusts the plants remaining useful life accordingly. In 2007, the Company increased the depreciation rate of TDMA technology
and certain other assets primarily in Brazil and Colombia. This change in estimate was made to better reflect the technological advances of telecommunications equipment and other operational decisions. The effect of the depreciation rate increase
was a Ps. 5,796,000 increase in depreciation for 2007. In 2008 the Company did not change the estimated useful life of its telephone plant.

In 2009, the subsidiary in Brazil prospectively increased the depreciation rate of its GSM telephone plant. Such increase represented an
additional charge of Ps. 4,461,748 to depreciation expense for 2009.

e) The most relevant information used in determining the
capitalized comprehensive financing cost is as follows:

a) A description of the principal changes in the caption licenses at December 31, 2007
and 2008 is as follows:

In May 2008, the Company announced that Conecel had been notified by the Consejo Nacional de
Telecomunicaciones de Ecuador that it had accepted Conecels proposal and payments terms regarding the license renewal for a period of 15 years. Conecel made an initial fixed payment of US$ 289 million (Ps. 4,003,439) to the
Ecuadorian government for the new 15-year concession and will subsequently make payments determined at 3.93% of the gross revenues on the services awarded.

On May 7, 2008, the Company was awarded the bid to provide mobile voice services as well as data and video transmission services
(PCS) in Panama. The license obtained by its subsidiary in Panama, Claro Panamá, S.A., grants the right to use and exploit 30 MHz in the 1900 MHz band over a period of 20 years. The amount paid by the Company for such license was US$
86 million (Ps. 895,626).

The Company acquired a license to operate 20 MHz of additional spectrum in five regions in
Brazil and 30 MHz of additional spectrum in six regions in such country. The amount paid by the Company in April 2008 for these new rights aggregated to Ps. 8,830,124 (approximately 1.4 billion Brazilian reais).

For the year ended December 31, 2007:

In March 2007, the Company acquired the shares of Telecomunicaciones de Puerto Rico, Inc. (see Note 9.I)

 In September 2007, the Company was ceded the rights to exploit the 1,895 and 1,970 MHz radio spectrum frequency F sub-bands to operate and provide
cellular telephony services in El Salvador. The amount paid by the Company for such licenses was Ps. 177,269.

 In September 2007, the
Company acquired a B band license for frequencies between 835 and 894 MHz to operate and provide cellular telephony services in Peru. The amount paid by the Company for such licenses was Ps. 251,965.

c) As a result of certain acquisitions, in 2007, the Company also acquired customer-related intangible assets for Ps. 685,679. These
intangible assets are amortized based on their estimated useful lives, which are 5 years.

d) Annual amortization expense
associated with licenses and trademarks is expected to be approximately Ps. 7,420,264 each year for the following five years.

Except for the fixed-rate senior notes, interest rates on the Companys debts are
subject to variances in international and local rates. The Companys weighted-average cost of borrowed funds at December 31, 2009 was approximately 5.8% (5.70% in 2008).

Such rate does not include interest, commissions or the reimbursements for Mexican tax withholdings (typically 4.9% of the interest
payment) that the Company must make to international lenders. In general, fees on financing transactions add ten basis points to financing costs.

The Company is subject to financial and operating covenants under the loan agreements. In
some cases, these covenants limit America Móvil or the guarantors ability to: pledge assets, carry out certain types of mergers, sell off all or substantially all of its assets and sell control over Telcel.

The covenants do not restrict the ability of the subsidiaries to pay dividends or make other distributions to the Company. The most
restrictive financial covenants require the Company to maintain a consolidated ratio of debt to EBITDA not greater than 4 to 1 and a consolidated ratio of EBITDA to interest expense of no less than 2.5 to 1 (based on the terms of the loan
agreements). For some of its loans, Telcel is subject to financial covenants similar to those applicable to América Móvil.

A number of the financing instruments are subject to either acceleration or repurchase at the holders option if there is a change
in the Companys control. At December 31, 2009, the Company has complied with all of the above-mentioned requirements.

At December 31, 2008 and 2009, approximately 87% and 85%, respectively, of the total outstanding consolidated debt is guaranteed by
Telcel.

c) Contingencies

América Móvil

NatTel

The plaintiff, NatTel, LLC (NatTel) sued the Company and others in a Connecticut state court in the United
States based on an August 2007 transaction where the Company purchased shares of Oceanic Digital Jamaica, Ltd. (ODJ) from ODC St. Lucia, a subsidiary of Oceanic Digital Communications, Ltd. (ODC), in which NatTel is a
minority shareholder. Under the agreement governing the transaction, the parties placed approximately US$15 million (approximately Ps. 195.9 million) in escrow with The Bank of New York, and the remaining purchase payments paid certain inter-company
debt owed by Oceanic to the majority shareholders in ODC  SAC Capital Associates, LLC and SAC Capital Advisors (collectively, SAC).

In the Connecticut action (State Suit), NatTel alleges that the entire transaction was intended to deprive NatTel of its fair
share of the sales proceeds, and structured so that SAC received the entire proceeds of the sale. NatTel seeks, inter alia, an order that it receive the approximately US$15 million placed in escrow. On February 7, 2008, the Company filed a
motion to dismiss for (i) lack of personal jurisdiction; and (ii) insufficient service. The motion principally argues that the Company does not have sufficient contacts with Connecticut to

support the state courts exercise of personal jurisdiction over it. The Company believes it has several other meritorious defenses to NatTels claims.

Concurrently with the State Suit, NatTel also initiated an adversary proceeding in connection with its bankruptcy case in the United
States Bankruptcy Court for the District of Connecticut (Bankruptcy Court), against many of the parties in the State Suit, including the Company. The adversary proceeding contains the same allegations as the State Suit.

After the filing of the adversary proceeding in Bankruptcy Court, defendants, excluding the Company, filed a motion in the District Court
for the District of Connecticut (District Court) to withdraw the reference (Motion to Withdraw) of the adversary proceeding, and send those proceedings to the District Court judge who had previously decided a related case
against NatTel.

In April 2008, the parties to the State Suit agreed to stay the State Suit pending a decision by the District
Court on the Motion to Withdraw. As of the date of the accompanying financial statements, the District Court has yet to decide on the Motion to Withdraw. Accordingly, the State Suit remains stayed.

The Company has not made provisions in the accompanying financial statements for this potential liability.

Cempresa

In May or June
of 2008, plaintiffs Centro Empresarial Cempresa, S.A. and Conecel Holding Limited (collectively, Plaintiffs), filed a suit in the Supreme Court of the State of New York against numerous defendants including the Company, certain of its
affiliates, subsidiaries and two members of its Board of Directors (collectively, Defendants), asserting breach of contract, fraud, fraudulent inducement, unjust enrichment and a claim for accounting. Plaintiffs sold a majority of their
shares in our Ecuadorian subsidiary, Consorcio Ecuatoriano de Telecomunicaciones, S.A.  Conecel (Conecel), to a subsidiary of Teléfonos de México, S.A.B. de C.V. (Telmex) in 2000. Telmexs holdings in
Conecel were included in the Companys spin-off from Telmex in 2000 and remain held by one of its subsidiaries. Plaintiffs kept a minority of the shares of Conecel.

Plaintiffs assert that one of their exit strategies with respect to the minority shares was a right to negotiate for an exchange of those
shares of the Company. Plaintiffs contend in the lawsuit that Defendants wrongfully deprive them of a share exchange and they seek the alleged value of the Companys shares they claim they would have receive, which Plaintiffs assert amount to
over US$900 million (approximately Ps. 11,754 million). Plaintiffs also seek punitive damages. Plaintiffs additionally assert that Defendants purposefully misrepresented the value of Plaintiffs minority shares to try to prevent a share
exchange. In 2003, Plaintiffs voluntarily sold their minority shares to Defendants, executing comprehensive releases as part of the transactions.

Defendants filed a motion to dismiss asserting numerous defenses, including statute of limitations, release, lack of damages, personal
jurisdiction for certain defendants, and the inability to add to a contract cause of action the fraud causes of action. In December 2008, the trial court denied the motion to dismiss and Defendants appealed. The appellate court stayed the case in
the trial court. The appeal is fully briefed and oral argument was held in April 2009.

Defendants believe they have numerous
meritorious defenses to Plaintiffs claims. In addition to the defenses contained in the motion to dismiss that are issues on appeal, Defendants do not believe that the Companys spin-off from Telmex triggered the share exchange provision.
Moreover, Defendants argue that a plain reading of the provision relating to the potential exchange of shares provides no right to a share exchange, but instead only a right to a good faith negotiation for a period of 20 days, for a
potential share exchange.

The Company has not made provisions in the accompanying financial statements for this potential
liability.

power in the market for termination (interconnection) of calls made as part of the local, national and international calling party pays system. Cofeco has issued a preliminary report (dictamen preliminar) finding that each operator,
including Radiomóvil Dipsa, S.A de C.V., (Telcel), has substantial market power in the market for interconnection to its own network.

Interested parties have the opportunity to submit information for Cofecos review before it issues a final report. Telcel has
provided extensive information to Cofeco, and the Company cannot predict when Cofeco will issue a final report or whether it will modify its preliminary findings.

The second Cofeco investigation, which commenced in April 2008 was initiated by an alleged Telcel subscriber -who ended up being
subscribed to another mobile operator- and is into whether Telcel has substantial market power in the nationwide market for voice services. In this investigation, Cofeco issued a preliminary report (dictamen preliminar) in November 2008 finding that
Telcel has substantial market power in the national mobile telephone services relevant market. The preliminary report was confirmed by the publication on February 10, 2010 in the Federation Official Gazette (Diario Oficial de la
Federación) of the relevant findings of the resolution relating to the existence of substantial market power in the nationwide market for voice services. In February 2010, Telcel filed an administrative proceeding (recurso administrativo de
reconsideración) before Cofeco. As a result of the aforesaid proceeding being rejected by Cofecto for analysis, Telcel filed an appeal (amparo indirecto) before an administrative judge against the rejection of the mentioned administrative
proceeding and the issuance, subscription and publication of the resolution which relevant findings where published on February 10, 2010 in the Federation Official Gazette (Diario Oficial de la Federación).

Under the Antitrust Law (Ley Federal de Competencia Económica) and the Telecommunications Law (Ley Federal de Telecomunicaciones),
if Cofeco makes a final finding of substantial market power concerning an operator, the Mexican Federal Communications Commission (Comisión Federal de Telecomunicaciones or Cofetel) can impose on that operator specific regulations
with respect to tariffs, quality of service and information. The Company cannot predict what regulatory steps might be taken in response to determinations by Cofeco.

CofecoMonopolistic practices investigations

Cofeco currently conducts four separate administrative proceedings against Telcel for alleged monopolistic practices. The first two
concern alleged actions by certain distributors of Telcel in relation to the purchase and sale of cellular phones to third parties. The third proceeding concerns to certain exclusivity agreements with some content providers. In each of these
investigations, Cofeco has determined that Telcel engaged in anti-competitive behavior, and it has imposed fines totaling Ps. 6.7 million in the aggregate and ordered that the alleged behaviors terminate immediately. Telcel has challenged
Cofecos determinations and fines in the courts and no final ruling has been issued.

The fourth investigation concerns
alleged monopolistic practices in the interconnection market. After having concluded the investigation stage, in October 2008 Cofeco notified Telcel a Writ of Probable Responsibility (Oficio de Probable Responsabilidad) for carrying out monopolistic
practices in the commuted termination services relevant market.

Interested parties to this investigation have the opportunity
to submit information for Cofecos review before it issues a final resolution. Telcel has provided extensive information to Cofeco, and the Company cannot predict when Cofeco will issue a final resolution or whether it will modify the Writ of
Probable Responsibility.

Adverse determinations against Telcel in any of these proceedings could result in material
fines, penalties or restrictions on our operations. Telcel has not made provisions in its financial statements for these potential liabilities since at the time Telcels most recent financial statements were published, the amount of the
possible contingency could not be reasonably estimated.

Interconnection Fees

Since 2005, there has been extensive controversy in Mexico concerning the interconnection fees payable by fixed-line operators to mobile
operators on fixed-to-mobile calls .The principal stages of the controversy, as they relate to interconnection with Telcel, are summarized below.



| |  |  | December 2004 Agreement. In December 2004, most Mexican telecommunications operators agreed on interconnection fees for the years 2005 through 2007.
The agreement provided for annual reductions of 10% and it was further contemplated that the reductions would be reflected in the tariffs charged by fixed operators to their customers. The agreed upon interconnection fees were as follows:
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

January 1, 2005 to December 31, 2005: Ps. 1.71 per minute or part thereof.

January 1, 2006 to December 31, 2006: Ps. 1.54 per minute or part thereof.

January 1, 2007 to December 31, 2007: Ps. 1.34 per minute or part thereof



| |  |  | August 2006 Cofetel Resolutions. Axtel, independently, and Avantel and Alestra, jointly, began proceedings with Cofetel to establish the applicable
interconnection fees for termination of public commuted traffic under calling party pays in local mobile service networks, between them and Telcel.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

As a result of the foregoing proceedings (desacuerdos de interconexión), on August 31, 2006, Cofetel issued two resolutions
(Axtel Resolution and Avantel/Alestra Resoultion) establishing local interconnection fees payable by the aforementioned carriers to Telcel for the years 2005 through 2010, as follows: from (i) January 1 to
December 31, 2005: Ps. 1.71 per interconnection minutes; (ii) January 1 to September 30, 2006: Ps. 1.54 per interconnection minutes; (iii) October 1, 2006 to December 31, 2007: Ps. 1.23 per
interconnection minute; (iv) January 1 to December 31, 2008: Ps. 1.12 per interconnection minute; (v) January 1 to December 31, 2009: Ps. 1.00 per interconnection minute; (vi) January 1 to
December 31, 2010: Ps. 0.90. Several of the foregoing fees were lower than the fees Telcel had agreed with other operators. In addition, Cofetel ruled that starting in 2007, interconnection fees would be determined by adding the total seconds
of all completed calls rounded to the next minute, rather than by rounding each call to the next minute, before calculating the sum of total network occupation.

In order to mitigate the effects of this change on Telcel, Cofetel authorized Telcel to collect a surcharge of 25% in 2007, 18% in 2008
and 10% in 2009 over the interconnection fees billed to Axtel, Avantel y Alestra. Telcel challenged the Axtel Resolution and the Avantel/Alestra Resolution.



| |  |  | August 31, 2006 Avantel/Alestra Resolution. Telcel challenged Cofetels August 2006 Avantel and Alestra Resolution on interconnection rates
between the aforesaid carriers and Telcel. In November 2009, said challenge was decided ruling that Cofetel is not empowered to add elements to the controversy set forth in the foregoing proceedings (desacuerdos de interconexión) and may not
resolve on matters which were not originally requested, for example interconnection fees for the years 2008 to 2010. Consequently, the challenged resolution was declared without effect and Cofetel was ordered to issue a new resolution establishing
interconnection fees for the years 2005 to 2007. Notwithstanding the foregoing, the ruling was silent in connection with the analysis and the assessment of several of the acts challenged by Telcel. Accordingly, on December 2009 Telcel challenged the
ruling before the competent courts. Likewise, Cofetel challenged the ruling. Avantel adhered to the challenges (recurso de revisión adhesiva).

| |  |  | August 31, 2006 Axtel Resolution  December 2007 Judicial Decision and January 2008 Cofetel Resolution  Telcel began a judicial
proceeding (juicio de amparo) challenging the Axtel Resolution on interconnection rates between Axtel and Telcel. In December 2007, the district court invalidated the Axtel Resolution in its entirety and directed Cofetel to issue a new resolution
covering solely the periods from 2005 through 2007. In January 2008, as directed by the court, Cofetel issued a resolution establishing interconnection rates between Telcel and Axtel for the periods from 2005 through 2007 on the same terms as
Cofetels August 2006 resolution. Telcel challenged this resolution as to the rates applicable for the aforementioned period. The ruling on the foregoing challenge was ruled adversely for Telcel in October 2009 arguing that, among others, the
model used by Cofetel to calculate interconnection fees is appropriate; accordingly, the judge determined that the interconnection fees resulting from Cofetels model should be: (i) Ps. 0.71 for 2005; (ii) Ps. 0.74 for 2006; and
(iii) Ps. 0.78 for 2007. Telcel challenged (recurso de revisión) the mentioned ruling arguing that although it may be true that the method used by Cofetel is appropriate, it is also true that the results obtained by the judge are
absolutely erroneous, since Cofetel did not use real and updated information while implementing their method, thus resulting in an incorrect outcome. Likewise, Cofetel challenged the ruling. Axtel adhered to the challenges (recurso de
revisión adhesiva).
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | December 2006 Agreements. In the fourth quarter of 2006, most industry operators, other than Axtel and Avantel, agreed on interconnection fees payable
for termination services for local and long-distance (national and international) calls in mobile networks under the calling party pays system for the years 2005 through 2010. These agreements contemplated continued reductions in fees,
as follows: (i) 2005: Ps. 1.71 per interconnection minute; (ii) 2006: Ps. 1.54 per interconnection minute; (iii) 2007: Ps. 1.34 per interconnection minute; (iv) 2008: Ps.1.21 per interconnection minute;
(v) 2009: Ps. 1.09 per interconnection minutes; and (vi) 2010: Ps. 1.00 per interconnection minute.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

2008 Proceedings Involving Axtel. In December 2007 and March 2008, Axtel initiated proceedings with Cofetel to establish interconnection
rates for the years from 2008 through 2011. In May 2008, prior to Cofetel issuing a resolution, Axtel obtained a court order against Cofetel to prevent Cofetel from issuing a resolution on interconnection between Axtel and Telcel. It also filed an
administrative review proceeding (recurso de revision), against the alleged negative to act (negativa ficta) of Cofetel with the Mexican Ministry of Communications and Transportation (Secretaría de Comunicaciones y Transportes or
SCT), that permits SCT to review the alleged decision by Cofetel. Axtel contended that Cofetel, by failing to issue a resolution on interconnection between Axtel and Telcel for interconnection fees for 2008 through 2011, had refused to
act, and asked SCT to review that refusal.



| |  |  | In July 2008 Telcel obtained a court order which prevented SCT from ruling on Axtels challenge to Cofetels supposed refusal to act on
interconnection fees between Axtel and Telcel.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Notwithstanding the foregoing, in September 2008, however,
SCT issued a resolution establishing interconnection fees for 2008 through 2011, as follows: (i) 2008: Ps. 0.5465 per interconnection minutes; (ii) 2009: Ps. 0.5060 per interconnection minute; (iii) 2010: Ps. 0.4705 per
interconnection minute; and (iv) 2011: Ps. 0.4179 per interconnection minute, based on the assumption that the valuation method consists of adding the actual duration of the calls measured in seconds. These fees are substantially less than
the fees agreed upon with the rest of the industry operators. Telcel challenged said resolution and, in October 2008, obtained a court order suspending the effects of it until a final ruling is issued.



| |  |  | April 2009 Cofetel Resolution  Avantel Interconnection Disagreement. In April 2009, Cofetel issued a resolution establishing the interconnection
fees for 2008 through 2010 applicable between Avantel (a subsidiary of Axtel) and Telcel for termination of public commuted traffic under the calling party pays system in Telcels mobile network, as follows: (i) 2008: Ps.
1.12 per interconnection minute plus a surcharge of 18% over the total interconnection minutes billed; (ii) 2009: Ps. 1.00 per interconnection minutes plus a surcharge of 10% over the total minutes billed; and (iii) 2010: Ps.
0.90 per interconnection minute without any surcharge, based on the assumption that the valuation method

| | consist of adding the actual duration of the calls measured in seconds and then rounding up to the next minute. In May 2009, Telcel judicially challenged said resolution and a final decision is
still pending.
| | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The Company considers that interconnection fees for fixed-to-mobile calls will continue, for
a while, to be the subject of litigation and administrative proceedings and the resulting uncertainty. We cannot predict when or how these matters will be resolved, and the competitive and financial effects of any resolution could be complex and
difficult to predict. Although the matters in dispute primarily concern one operator, Axtel (and its subsidiary Avantel), if those matters are resolved adversely to us through a final, non-appealable resolution or decision from Cofetel, SCT or the
courts, the impact could be material because Telcel would be required to offer to the other operators any more favorable fees it is required to provide, as of the date of said final, non-appealable resolution or decision, to Axtel and/or Avantel.
This could materially reduce Telcels interconnection revenues in future periods. Also, depending on how the disputes are resolved, there could be contractual claims among Axtel and/or Avantel, and Telcel for reimbursement or payment, as the
case maybe, of amounts paid or left unpaid between Telcel and Axtel and/or Avantel in respect to certain time periods from 2005 to 2010.

February 2009 Interconnection Plan

On February 10, 2009, Cofetel published a Fundamental Technical Plan of Interconnection and Inter-operability (Plan Técnico
Fundamental de Interconexión e Interoperabilidad or Plan). The Plan addresses technical, economical and legal conditions of interconnection. With respect to interconnection fees, the Plan establishes a process for developing an
economic model over a relatively brief period and then applying the economic model to determine fees, which, it is suggested, could override the existing fee agreements among operators. The Plan also contemplates asymmetrical and discriminatory
treatment for operators with the largest number of access points, including specific technical and legal requirements and different economic, technical and legal conditions from other operators.

At this time, Telcel cannot predict the effects that might result from the implementation of the Plan. They could be substantially
different from the potential effects of the regulatory steps described above with respect to fixed-to-mobile interconnection. It is also difficult to anticipate the timetable for implementation of the Plan.

In March 2009, Telcel challenged the Plan in the Mexican courts. In April 2009, Telcel obtained a court order suspending the effects of
the Plan as they relate to Telcel pending resolution of its judicial challenge. As of the date of the accompanying financial statements, the challenge remains pending.

Short Message Services (SMS)

Under the terms of its concessions for the 850 megahertz spectrum, Telcel must pay to the Mexican federal government a royalty based on
gross revenues from concessioned services. The royalty is levied at rates that vary from region to region and average approximately 6%.

Telcel believes that short message services are value-added services, which are not concessioned services, and that revenues from short
message services should not be subject to this royalty.

In related proceedings, Cofetel has ruled that short text messages
are subject to the interconnection regulatory regime and that such services do not constitute value-added services. Telcel is currently disputing these issues in an administrative proceeding, but has made provisions in its financial statements for
this potential liability.

Trademarks Tax Assessments

On March 3, 2006, the Mexican Tax Administration Service (Servicio de Administración Tributaria, or SAT) notified
Telcel of an assessment of Ps. 281.7 million (Ps. 155.8 million plus adjustments, fines and late

fees) as a result of a tax deduction made by Telcel in 2003 of Ps. 1,267.7 million in connection with royalty payments made to another of our subsidiaries for the use of certain trademarks.
In June 2007, the SAT notified us of an additional assessment of Ps. 541.5 million (Ps. 258.5 million plus adjustments, fines and late fees) as a result of a tax deduction made by us in 2003 in connection with the aforementioned royalty
payments. The Company and Telcel believe that these deductions were made in accordance with applicable law and have challenged the validity of these assessments.

In December 2007, the SAT notified Telcel of a new assessment of Ps. 453.6 million (Ps. 243.6 million plus adjustments, fines
and late fess) in connection with a deduction of advertising expenses made by Telcel in 2004 in the amount of Ps. 1,678.6 million. The SAT is challenging the validity of this deduction, alleging that the deduction is unfounded because Telcel is
already paying a royalty for the use of the trademarks. Telcel believes that the SATs argument is unfounded and has challenged the assessment in court.

Based on these assessments, the Company expects that the SAT will challenge deductions made during 2005, 2006 and 2007 for royalty
payments and/or expenses associated with the trademarks. Telcel has not made specific provisions in its financial statements for these potential liabilities.

Comcel

Voice over IP

In March 2000, the Colombian Industry and Commerce Superintendence (Superintendencia de Industria y Comercio or SIC) issued
Resolution No. 4954, requiring Comunicación Celular, S.A. (Comcel) to pay a fine of approximately US$100 thousand (approximately Ps. 1.3 million) for alleged anti-competitive behavior. In addition to this administrative fine,
the SIC ordered Comcel to pay damages to other long distance operators. The long distance operators estimated their damages to be US$70 million (approximately Ps. 904.2 million). Comcel requested an administrative review of the damages decision,
which was denied in June 2000. Comcel appealed, and the appeal was rejected in November 2000. Comcel resubmitted the appeal in February 2001. Comcel also filed a special action in court challenging the denial of the administrative review.

Following a series of court proceedings, a Colombian appeals court in June 2002 ordered that Comcels February 2001
appeal be granted and that the administrative decision against Comcel be reviewed. After additional proceedings, the Constitutional Court revoked the June 2002 decision and ordered the continuance of the procedure for the determination of damages to
the other operators.

In January 2008, SIC determined that Comcel was required to pay the long distance operators
approximately US$1.8 million (approximately Ps. 23.5 million, which represents a reduction of approximately 95% of the original amount claimed by the long distance operators). In February 2008, Comcel appealed the SICs resolution on the
grounds that Comcel had not caused any damage nor it incurred in any liability.

In June 2009, Bogotas Judicial District
Court of Appeals (Tribunal Superior del Distrito Judicial de Bogotá), confirmed SICs January 2008 resolution. As a result, Comcel timely paid US$1.8 million fine. As a result of the foregoing, this contingency has been duly terminated.

Distributors

In February 2007, Comcel was notified of an arbitration proceeding initiated against it by Tecnoquímicas, S.A., which was a
distributor of prepaid cards of Comcel until July 2006. In the proceeding, the distributor alleges breach of contract and commercial liability on the part of Comcel. Claimant seeks to recover approximately US$35 million (approximately Ps. 457.1
million) from Comcel. On July 13, 2009, the arbitration tribunal decided that Comcel had to pay Tecnoquímicas, S.A., US$13 million (approximately Ps. 169.8 million), which were timely paid by Comcel. As a result of the foregoing, this
contingency has been duly terminated.

Dominant position

In September 2009, the Colombian Telecommunications Regulatory Commission (Comisión de Regulación de Telecomunicaciones de
Colombia or CRT) issued a series of resolutions stating that Comcel has a dominant position in Colombias market for outgoing mobile services. Under Colombian law, a market participant is considered to have a dominant position in a
specified market if the regulators determine that it has the capacity to control the conditions in that market. The CRT made its determination based on Comcels traffic, revenues and subscriber base. The resolutions also included regulations
that would require Comcel to charge rates (excluding access fees) for mobile-to-mobile calls outside the Comcel network (off net) that are no higher than the fees charged for mobile-to-mobile calls within the Comcel network (on
net) plus access fees. The regulations were first implemented on December 4, 2009 and Comcel does not expect them to have a material impact on its business and results of operations in Colombia.

Brazil

Anatel Inflation-Related
Adjustments

The Brazilian Federal Communications Commission (Agência Nacional de Telecomunicações or
ANATEL) has challenged each of Tess, S.A., or Tess, and ATL-Telecom Leste, S.A., or ATL, regarding the calculation of inflation-related adjustments due under these companies concession agreements with
ANATEL. Forty percent of the concession price under each of these agreements was due upon execution and 60% was due in three equal annual installments (subject to inflation-related adjustments and interest) beginning in 1999. Both companies have
made these concession payments, but ANATEL has rejected the companies calculation of the inflation-related adjustments and requested payment of the alleged shortfalls.

The companies have filed declaratory and consignment actions in Brazilian courts seeking resolution of the disputes. The court of first
instance ruled against ATLs filing for declaratory action in October 2001 and ATLs filing for consignment action in September 2002. Subsequently, ATL filed appeals which are pending. The court of first instance ruled against Tess
filing for consignment action in June 2003 and against Tess filing for declaratory action in February 2009. Tess filed an appeal which is pending. In December 2008, ANATEL charged Tess approximately US$160 million (approximately Ps. 2,089.6
million). Tess filed an appeal and consequently payment has been suspended until the final ruling is issued. In March 2009, ANATEL charged ATL approximately US$100 million (approximately Ps. 1,306 million). ATL filed an appeal and consequently
payment has been suspended until the final ruling is issued.

The aggregate contested amounts are approximately US$240 million
(approximately Ps. 3,134.4 million) (including potential penalties and interest). On December 31, 2005, both ATL and Tess were merged into BCP, S.A. (BCP). In April 2008, BCP changed its name to Claro S.A. (Claro
Brasil).

Claro Brasil has made specific provisions in its financial statements for these potential liabilities.

BNDESPar

Prior to the acquisition of Telet, S.A. (Telet) and Americel, S.A. (Americel) by Telecom Americas Limited
(Telecom Americas), BNDESPar, a subsidiary of BNDES, the Brazilian development bank, had entered into investment and other shareholder agreements with Americel, Telet and certain of their significant shareholders. Under these agreements,
BNDESPar had the right, among others, to participate in the sale of shares of Telet and Americel in the event of certain transfers of control, for so long as BNDESPar held 5% of the share of capital in those companies.

In October 2003, Telecom Americas increased the capital of each of Telet and Americel and BNDESPars ownership fell below 5% from
approximately 20% in each, as it elected not to exercise its preemptive rights. Subsequently, BNDESPar sent official notices to Telet and Americel reserving its rights under the agreements

##### Table of Contents

with respect to certain past transfers of shares. In November 2004, BNDESPar filed a lawsuit with the competent court of Rio de Janeiro claiming that BNDESPar is entitled to sell its shares in
Telet and Americel to Telecom Americas for approximately US$164 million (approximately Ps. 2,141.8 million). The Company does not believe that BNDESPar has valid grounds for its claims against Telecom Americas. The Company cannot provide assurance,
however, that Telecom Americas will ultimately prevail in this dispute. Claro Brasil has not made specific provisions in its financial statements for this potential liability.

Lune Patent Case

A
Brazilian company claims that wireless operators in Brazil have infringed its patent over certain caller ID technology. The plaintiff first brought a patent infringement case in a state court in Brasília, Federal Capital of Brazil, against
Americel and later brought cases, as part of two separate proceedings, against other 23 defendants. Although the Company believes that the patent does not cover the technology that is used by Americel to provide caller ID services, Americel lost the
case at the trial level and on first appeal. After the judgment against Americel was rendered, a federal court in Rio de Janeiro, Brazil, rendered a preliminary injunction decision suspending the effects of the patent, in an action filed by a
supplier of caller ID technology. This injunction was later upheld on appeal, and the proceeding for judicial review on the merits of the validity of the patent is in its initial stages.

Americel filed three special appeals against the decision of the state court in Brasília, seeking review at the Superior Court of
Justice (which is the highest court in Brazil to decide on questions of federal law) and Supreme Court (the highest court in Brazil to decide on questions of constitutional law). The Court of Appeals has determined that two of Americels
special appeals will be heard by the Superior Court of Justice. Americels request for a special appeal before the Supreme Court was denied. Americel filed a motion requesting the reversal of this decision which is still pending.

The cases against the other operators are currently suspended as a result of the preliminary injunction suspending the effects of the
patent. The plaintiff has brought these cases to the same state trial court that heard the case against Americel, but the defendants have requested that the cases be remitted to another court on jurisdictional grounds. The Americel judgment does not
bind other state courts or federal courts of Brazil. The Company does not expect that there will be a resolution of these other cases within this year.

In the case against Americel, the plaintiff has requested the court to initiate the necessary proceedings for the execution of judgment.
The court has estimated that the award for damages could amount to as much as approximately US$270 million (approximately Ps. 3,526.2 million). In September 2006, the Higher Court of Justice of Brazil unanimously ruled to stay the trial, due to the
injunction suspending the validity of the patent in question. In September 2009, Lune filed before the Higher Court of Justice of Brazil a motion to revert the ruling to stay the trial. However, Americel obtained a favorable resolution that
maintained the decision to stay the trial until a ruling has been issued in the process held before the federal court in Rio de Janeiro. Lune has challenged said resolution before the Superior Court, but the resolution to stay the trial was
unanimously upheld. The Company expects that the trial will remain stayed as long as the patent remains suspended. Furthermore, Americel benefits from a limited contractual indemnity from its equipment suppliers (Nortel Networks) in respect of
trademark infringement. The process remains suspended by the Superior Court of Justice. Americel has not made specific provisions in its financial statements to cover these potential liabilities.

Tax Assessments against Americel

In December 2005, the Brazilian Federal Revenue Service (Secretaria da Receita Federal do Brasil) issued three tax assessments against
Americel in respect of withholding income taxes and PIS and COFINS taxes (contributions levied on gross revenue) for 2000 through 2005. As of February 2010, the total amount of the tax assessments was R$ 242 million (approximately Ps.
1,815 million), including R$ 89.9 million (approximately Ps. 673.4 million) of taxes and contributions plus fines and interest. Americel has challenged these assessments, and



F-49

##### Table of Contents

its challenge is pending before the Brazilian Taxpayers Council (Conselho Administrativo de Recursos Fiscais) in Brasilia. Americel did not make any specific provisions in its financial
statements to cover these potential liabilities.

Tax Assessments against ATL

In March 2006, the Brazilian Federal Revenue Service issued two tax assessments against ATL in respect of certain tax credits claimed by
ATL and derived from non-cumulative contributions levied on gross income (PIS and COFINS). Under the Brazilian tax legislation, the calculation and payment of PIS and COFINS has two different regimes, the cumulative and non-cumulative regimes. The
applicability of a regime depends on the nature of the company and its business sector. The cumulative regime applies to revenues derived from the provision of telecommunications services, while the sale of handsets is taxed under the non-cumulative
regime. The non-cumulative regime is based on the value-added concept and allows the taxpayer to claim tax credits corresponding to preceding transactions. ATL (as well as other of the Companys Brazilian subsidiaries) offsets the tax credit
derived from the non-cumulative regime for the sale of handsets (the balance between the purchase and the sale of handsets), against contributions owed under the cumulative regime. The Brazilian Federal Revenue Service is arguing that tax credits
derived from the non-cumulative regime may not be used to offset contributions owed under the cumulative regime. The total amount of the tax assessments is approximately R$54.9 million (approximately Ps. 411.8 million), including R$24.1 million
(approximately Ps. 180.8 million) of taxes and contributions plus R$30.8 million (approximately Ps. 231 million) of fines and interest. Claro Brasil has challenged these assessments, and the challenge is pending before the Brazilian Taxpayers
Council.

On December 31, 2005, ATL was merged into BCP. In April 2008, BCP changed its name to Claro Brasil.

Claro Brasil did not make any specific provisions in its financial statements to cover these potential liabilities.

Conecel

Tax Assessments

During 2008, Conecel filed administrative proceedings before the Ecuadorian Revenue Services (Servicio de Rentas Internas
de Ecuador, or the SRI), challenging US$127 million (approximately Ps.1,658.6 million) of certain tax assessments notified by the SRI amounting to U.S.$138 million (not including interest and penalties) (approximately Ps. 1,802.3) which
related to special consumption (ICE), value-added, income and withholding taxes for the years 2003 to 2006. In March 2008, Conecel paid to the SRI U.S.$14.3 million (approximately Ps. 186.8 million) in respect of the aforesaid tax assessments.

In December 2008, the SRI notified Conecel of a resolution that denied the challenges filed by Conecel against the tax
assessments. As a result of the foregoing, on January 15, 2009, Conecel filed a lawsuit before a Tax Court in Guayaquil (Tribunal Distrita de lo Fiscal de Guayaquil) challenging the tax assessments, attaching a bank guarantee of US$12.7
(approximately Ps. 165.9 million), which represented 10% of the contested amount.

In May, 2009, the SRI filed the answer to
the complaint. Immediately thereafter, the Tax Court opened the evidentiary stage of the proceedings and summoned the parties to several document exhibition hearings, which took place in Conecel and the SRI. Accountant experts, certified by the
parties, were also summoned to the hearings and were responsible for issuing expert opinions as to the document exhibition process. The latest expert opinion was filed before the Tax Court on January 27, 2010.

|18. | Income Tax, Flat Rate Business Tax and Asset Tax
|--- | ------------------------------------------------

I) Mexico

a) Effective
January 2002, the Ministry of Finance and Public Credit authorized América Móvil to consolidate its tax results with those of its Mexican subsidiaries.

Tax consolidation is a legal precept in Mexico that consists of presenting the tax results of all Mexican subsidiaries and the controlling
company (América Móvil, as a legal entity) together as a single legal entity.

b) Asset Tax (AT) and Flat Rate Business Tax (FRBT)

Through 2007, the asset tax was payable based on 1.25% of the average value of most assets.

Beginning January 1, 2008, the Flat-Rate Business Tax (FRBT) Law abolished the Asset Tax Law. The FRBT Law establishes a procedure
for determining asset tax payable through December 2007, which can be recovered beginning in 2008.

Current-year FRBT is
computed by applying the 16.5% (17.0% for 2009) to income determined on the basis of cash flows, net of authorized credits.

FRBT credits result mainly from the negative FRBT base to be amortized, salary and social security contribution credits, and credits
arising from the deduction of certain assets, such as inventories and fixed assets, during the transition period as of the date on which the FRBT became effective.

FRBT is payable only to the extent it exceeds income tax for the same period. To determine FRBT payable, income tax paid in a given
period is first subtracted from the FRBT of the same period.

When the FRBT base is negative because deductions exceed taxable
income, there is no FRBT payable. The amount of the negative base multiplied by the FRBT rate results in a FRBT credit, which may be applied against income tax for the same year or, if applicable, against FRBT payable in the next ten years.

c) Corporate income tax rate

i) The corporate income tax rate for 2007, 2008 and 2009 was 28% in Mexico.

At December 31, 2008 and 2009, the table shown above includes the deferred tax asset of TracFone,
Enitel and Puerto Rico. The deferred tax asset in Puerto Rico refers to the income tax benefit this subsidiary will enjoy upon settling its labor obligations. Deferred taxes also include an account receivable arising from differences in the book and
tax values of the plant and equipment of Comcel in Colombia.

Additionally, there is a deferred income tax asset recognized in
Brazil resulting from tax losses obtained at the time of acquisition and subsequent to the acquisition date, as well as other temporary differences. In 2008 and 2009, the valuation allowance related to this deferred income tax asset was reduced,
resulting in a credit of Ps. 4,428,593 and Ps. 6,419,448, respectively, to deferred income tax expense.

g) Changes in Mexican
tax legislation effective beginning in 2010

On December 7, 2009, the Mexican Congress passed a tax reform bill that
includes an increase in the corporate income tax rate from 28% to 30% from 2010 until 2012, which will then decrease to 29% for 2013 and 28% for 2014 and thereafter.

The effect of such change in the income tax rate represented a decrease of Ps. 279,837 in the Companys deferred income tax
liability, since the reversal amount of certain differences in balance sheet accounts for financial and tax reporting purposes was calculated using the 30% statutory rate.

Dividends paid from sources other than the Net taxed profits account (CUFIN) will be subject to the following gross-up or split factors:



|                    |  |                
|------------------- |  | ---------------
|Year                |  | Gross-up factor
|2009                |  | 1.3889         
|2010 to 2012        |  | 1.4286         
|2013                |  | 1.4085         
|2014 and thereafter |  | 1.3889

Tax consolidation

Additionally, the 2010 Mexican Tax Reform establishes a procedure for a partial or total deconsolidation for certain items that, under the
tax consolidation regulations previously permitted under the law, had been deferred from 2004 to date. Such items are as follows:



| | i) | Tax losses of the controlling company or controlled companies
| | -- | -------------------------------------------------------------



| | ii) | Loss on sale of shares issued by controlled companies
| | --- | -----------------------------------------------------



| | iii) | Book dividends paid from sources other than the CUFIN
| | ---- | -----------------------------------------------------



| | iv) | Adjustments from changes in equity interest percentages
| | --- | -------------------------------------------------------



| | v) | As of 2010, the deferred-payment procedure must include the difference in CUFIN between the controlled companies and the controlling company.
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------

The payment schedule for aforementioned items in the case of a partial deconsolidation would be remitted as follows depending on the year
in which the original tax benefit was taken in the tax consolidation:



|     |  |                       
|---- |  | ----------------------
|Year |  | Portion to be remitted
|2010 |  | 25%                   
|2011 |  | 25%                   
|2012 |  | 20%                   
|2013 |  | 15%                   
|2014 |  | 15%                   

The Companys
deferred tax consolidation items are represented primarily by tax losses that were previously benefited in the Companys tax consolidation but that now should be remitted. These amounts may now be carried forward on an individual basis by the
individual companies for a period of ten years. Such amounts are presented in the deferred tax table above, with retrospective disclosure for comparable amounts in the prior year.

h) At December 31, 2009, the balance of the Companys Restated contributed capital account (CUCA) and Net tax profit account
(CUFIN) aggregated Ps. 105,262,200 and Ps. 3,758,442, respectively.

II) Subsidiaries abroad

a) Net income

The foreign subsidiaries determine their income tax based on the individual results of each subsidiary and in conformity with the specific
tax regime of each country. An analysis of the aggregate pretax income and aggregate tax provisions of these subsidiaries in 2007, 2008 and 2009 is as follows:



|                                                   |  |              |            |      |     |            |  |     |

The significant tax loss carryforwards in the
different foreign countries in which the Company operates have the following expiration dates and characteristics:

i) In
Brazil, tax loss carryforwards do not expire; however, the carryforward amount that may be utilized in each year may not exceed 30% of the tax base for such year, so that in the year on which taxable income is generated, the effective tax rate is
25% rather than the 34% corporate rate.

ii) In Chile, the tax loss carryforwards have no expiration date. The corporate tax
rate is 17%; therefore, at the time tax losses are incurred taxpayers may enjoy a maximum 17% benefit of the amount of the loss.



|19. | Segments
|--- | --------

América
Móvil operates primarily in one operating segment (cellular services); however, as mentioned in Note 1 above, the Company has international telecommunications operations in Mexico, Guatemala, Nicaragua, Ecuador, El Salvador, Brazil,
Argentina, Colombia, United States, Honduras, Chile, Peru, Paraguay, Uruguay, the Dominican Republic, Puerto Rico, Jamaica, and Panama. The accounting policies for the segments are the same as those described in Note 2.

Companys management analyzes the financial and operating information by geographical segment. However, the information for
significant countries, whose revenues aggregates more than 10% of consolidated revenues and more than 10% of consolidated assets, is presented separately.

|20. | Subsequent Events
|--- | -----------------

a) On
January 13, 2010, the Company announced that it will launch a tender offer to the shareholders of Carso Global Telecom, S.A.B. de C.V. (Telecom) for the exchange of the shares they hold in Telecom for shares in América
Móvil. The exchange ratio would be 2.0474 to 1, which means that the shareholders of Telecom would receive 2.0474 shares of América Móvil per each share of Telecom

Should this offer be accepted by the shareholders of Telecom, América Móvil would indirectly acquire 59.4% of the
outstanding shares of Teléfonos de México, S.A.B. de C.V. (Telmex) and 60.7% of the shares of Telmex Internacional, S.A.B. de C.V. (Telmex Internacional). At December 31, 2009, the net debt of Telecom was
approximately Ps. 22,017 million. América Móvil also announced that it will make an offer to the shareholders of Telmex Internacional for the exchange or purchase of shares in Telmex Internacional not already owned by Telecom (39.3%).
The exchange ratio would be 0.373 per share of América Móvil share per share of Telmex Internacional or, if paid in cash, the purchase price would be Ps. 11.66 per share.

In the event that, at completion of the processes described above, a sufficient number of shares are obtained, it is intended to delist
both Telecom and Telmex Internacional in the various securities markets in which their shares are registered. These transactions were approved by the Board of Directors of América Móvil on January 13, 2010.

On February 11, 2010, the Comisión Federal de Competencia Económica (Mexican Federal Antitrust Commission
or COFECO) approved these transactions through a resolution that confirms that the transaction would represent a corporate restructuring that would have no bearing whatsoever on the structure of the markets in which the companies
involved do business.

The completion of the Proposed Offers will also be subject to receiving regulatory approvals and to
other conditions. It is possible that if not all such approvals or conditions are obtained or met we will not complete the Proposed Offers. Accordingly, there can be no assurance as to when we will launch the Proposed Offers or as to whether or when
they will be completed.

b) On March 4, 2010, the Company issued Domestic Senior Notes based on the program that was
authorized by the National Banking and Securities Commission and is registered under the number 2723-4.15-2008-006 in the National Securities Register.

The issuance was for an amount of Ps. 14,881,331, in three tranches, one for Ps. 4,600,000, with a maturity in February 2015, at an
interest rate of 5.32%; the second tranche was issued in Investment Units (IU) that amounted to 743,487,900 (IU) (Ps. 3,281,331), with a maturity in February 2020, at an interest rate of 4.4% and the last tranche amounted to Ps. 7,000,000, with a
maturity in February 2025, at an interest rate of 8.6%.

c) On March 9, 2010, the Company announced in its Board of
Directors meeting that they decided to submit to the Ordinary General Shareholders Meeting to be held on or before April 30, 2010, a proposal to make a payment of a cash dividend from the consolidated net profit tax account of Ps. 0.32
(thirty two peso cents), payable in a single installment, to each of the series of shares AA, A and L that represent the capital stock of AMX (which includes the preferred dividend correspondent to the series
L shares) and to increase in Ps. 50,000 million the outstanding amount to repurchase shares in accordance with article 56 of the Securities Market Law.

d) On March 23, 2010, the Company issued Senior Notes for an amount of US$ 4,000 million, in three tranches, one for US$
750,000, with a maturity in March 2015, at an interest rate of 3.625%; the second tranche amounted to US$ 2,000,000, with a maturity in March 2020, at an interest rate of 5.0% and the last tranche amounted to US$ 1,250,000, with a maturity in March
2040, at an interest rate of 6.125%. The Senior Notes require registration with the SEC, which is expected to take place in the coming months.

|21. | Differences between Mexican FRS and U.S. GAAP
|--- | ---------------------------------------------

The Companys consolidated financial statements are prepared in accordance with Mexican Financial Reporting Standards (Mexican
FRS), which differ in certain respects from generally accepted accounting principles in the United States (U.S. GAAP).

As previously described in Note 2 f), effective January 1, 2008, the Company ceased to recognize the effects of inflation in its
financial statements as required by Mexican FRS B-10. However, as required by such new standard, the financial statement amounts that were previously reported remained unchanged, and the inflation adjustments previously recognized have been
maintained in their corresponding caption. This new standard requires that the restated amounts of non-monetary assets as reported at December 31, 2007 to become the carrying amounts for those assets effective January 1, 2008. The carrying
amounts will also affect net income in subsequent periods. For example, depreciation expense after the adoption of Mexican FRS B-10 is based on carrying amounts of fixed assets that include inflation adjustments recorded prior to the adoption of
Mexican FRS B-10.

The Mexican FRS and US GAAP amounts included in this Note, as they relate to the year ended
December 31, 2009 and 2008, are presented in the carrying amounts as required by MFRS B-10. The effects of inflation that were recorded prior to 2008 have not been reversed in the reconciliations to US GAAP.

The Mexican FRS and U.S. GAAP amounts, included throughout Note 21 for the year ended December 31 2007, are presented in constant
Mexican pesos as of December 31, 2007. The reconciliation to U.S. GAAP for the year ended December 31, 2007 does not include the reversal of the adjustments to the financial statements for the effects of inflation required under Mexican
FRS (Bulletin B-10), except for the methodology for restatement of imported telephone plant, because the application of Bulletin B-10 represented a comprehensive measure of the effects of price level changes in the Mexican economy as permitted by
the SEC.

The principal differences between Mexican FRS and U.S. GAAP, as they relate to the Company, are described below
together with an explanation, where appropriate, of the method used to determine the adjustments that affect operating income, net income, total shareholders equity and cash flows provided by operating, investing and financing activities.

Accounting Standards Codification

On July 1, 2009, FASB Accounting Standards Codification (ASC) became the sole source of authoritative U.S. GAAP
recognized by the Financial Accounting Standards Board (FASB) to be applied by nongovernmental entities for financial statements issued for interim and annual periods ending after September 15, 2009. The ASC did not change U.S. GAAP, but rather
combined the sources of U.S. GAAP and the framework for selecting among those sources into a single source.

Statement of Income
Information

Cost of sales and services, as shown in the statement of income, includes cost of sales of telephone equipment
in the amount of Ps. 69,979,814, Ps. 75,116,949 and Ps. 76,187,077, for the years ended December 31, 2007, 2008 and 2009, respectively.

Cash Flow Information

As described in Note 2 z.1), the Company adopted Mexican FRS B-2, Statement of cash flows, on January 1, 2008. The cash flow
statements as prepared by the Company under Mexican FRS for the years ended December 31, 2008 and 2009 comply with International Accounting Standard (IAS) No. 7, Cash Flow Statements, as issued by the International
Accounting Standards Board (IASB). Therefore, no separate US GAAP statements of cash flow are presented for 2008 and 2009.

##### Table of Contents

However, the financial statements under Mexican FRS for the year ended December 31,
2007, include the presentation of the consolidated statement of changes in financial position in accordance with Bulletin B-12, as described in Note 2 z.1). The changes in the consolidated financial statement balances included in this statement
constitute resources provided by and used in operating, financing and investing activities stated in constant pesos (including monetary and foreign exchange gains and losses).

ASC No. 230, Statement of Cash Flows, does not provide guidance with respect to inflation adjusted financial statements. For
2007, in accordance with Mexican FRS, the changes in current and long-term debt due to re-expression into constant pesos, including the effect of exchange differences, are presented in the statement of changes in financial position in the financing
activities section. The Company has adopted the guidance issued by the AICPA SEC Regulations Committees International Practices Task Force in its meeting held on November 24, 1998, encouraging foreign registrants that file price level
adjusted financial statements to provide cash flow statements that show separately the effects of inflation on cash flows. Also, under U.S. GAAP non-cash investing activities are not reported in the statement of cash flows, whereas in the statement
of changes in financial position prepared under Mexican FRS, non-cash transactions that affect the financial structure of an entity must be presented separately.

If the monetary gain and the exchange gain or loss related to the debt reported in the year ended December 31, 2007 were treated as
components of operating activities, summarized consolidated statements of cash flows derived from information prepared in accordance with U.S. GAAP would be as follows:

Capitalized Interest

Under U.S. GAAP, financing cost incurred during the construction period must be considered as an additional cost of constructed assets to
be capitalized in plant, property and equipment and depreciated over the useful lives of the related assets. The amount of the capitalized interest for U.S. GAAP purposes was determined by applying the weighted-average rate of interest of financing.

Starting January 1, 2007, the Company commenced capitalizing comprehensive cost of financing on assets under
construction (whose construction started on or after January 1 2007), which include interest expense, monetary gains directly associated with borrowings (when operating in an inflationary environment) and, in the case of borrowings denominated
in a foreign currency, foreign currency exchange gains (losses).

The reconciling item for 2007 includes the reversal of the
monetary gain and foreign exchange results capitalized under Mexican FRS, related to borrowings denominated in foreign currencies and corresponding depreciation. In 2008 and 2009, the reconciling item corresponds to the reversal of foreign exchange
gain (loss) capitalized under Mexican FRS, related to borrowings denominated in foreign currencies, as well as the depreciation effect of these differences in prior years.

Valuation of Plant, Property and Equipment

Through December 31, 2007, for Mexican FRS purposes, plant, property and equipment of non-Mexican origin were restated based on the
rate of inflation in the respective country of origin at the prevailing exchange rate at the balance sheet date (specific-indexation method), while plant, property and equipment of domestic origin were restated based on the NCPI.

The alternate restatement method allowed up to December 31, 2007 by Bulletin B-10,
which was the one adopted in 1997 by the Company, is not acceptable for U.S. GAAP purposes; consequently, the difference between this method and the restatement of plant, property and equipment based on the NCPI was taken to the U.S. GAAP
reconciliations subsequently presented.

As a result of this adjustment, plant, property and equipment and shareholders
equity increased by Ps. 4,923,748 as of December 31, 2008 and Ps. 2,563,127 as of December 31, 2009 and depreciation expense increased by Ps. 3,072,871, Ps. 2,668,181 and Ps. 2,360,622, in 2007, 2008 and 2009, respectively.

Deferred Income Tax and Deferred Employee Profit Sharing

As mentioned in Note 2 s), under Mexican FRS, deferred income tax is determined on all differences in balance sheet accounts for financial
and tax reporting purposes, using the enacted income tax rate at the balance sheet date, which is substantially in conformity with ASC No. 740, Income Taxes, except for the treatment of deferred taxes on effect of translation of foreign
entities.

The Company is required to pay employee profit sharing in accordance with Mexican labor law. Deferred employee
profit sharing under US GAAP is determined following the guidelines of ASC No. 740.

Under Mexican FRS, employee
profit sharing is presented as Other expenses, net; whereas under US GAAP, such expenses are presented in operating costs and expenses.

As described in Note 2 r), under Mexican FRS the Company began recognizing deferred employee profit sharing, using the asset and
liability method, beginning January 1, 2008. Under this method, deferred profit sharing is computed by applying the 10% rate to all differences between the values of all assets and liabilities for financial and tax reporting purposes, which is
consistent with ASC 740.

Under Mexican FRS B-15, entities must recognize deferred tax consequences attributable to the effect
of translation of foreign entities following the guidelines of MFRS D-4. However under US GAAP, deferred tax consequences on unremitted foreign earnings are accounted for as a temporary difference, unless the tax law provides a means by which
the investment in a subsidiary may be recovered or transferred tax free. Therefore, the Company has eliminated the deferred tax consequences on the effect of translation of its foreign operations in the reconciliation of shareholders equity
between Mexican FRS and US GAAP. In 2009, the Company repatriated a portion of its previously unremitted foreign earnings, for which incremental taxes were incurred in Mexico. Thus a corresponding deferred tax liability related to the incremental
taxes to be paid on unremitted earnings of those foreign subsidiaries presumed to be remitted in future years was recognized in 2009. This matter is discussed further below.

earnings of Ps. 21,562,097 of those foreign subsidiaries. At December 31, 2009, undistributed earnings of the Companys remaining foreign subsidiaries, which amounted to approximately Ps. 26,211 million were considered indefinitely
reinvested.

Employee benefit obligations

ASC 715, Compensation  Retirement Benefits, requires (1) recognition on the balance sheet of an asset for a defined
benefit plans overfunded status or a liability for a plans underfunded status, (2) measurement of a defined benefit plans assets and its obligations that determine its funded status as of the end of the employers fiscal
year, and (3) recognition of the changes in the funded status of a defined benefit postretirement plan as a component of other comprehensive income in the year the changes occur.

The components of the plan funded status that is reflected in the consolidated balance sheet as of December 31, 2008 and 2009 are as

Accordingly, the statement of changes in shareholders equity at December 31, 2008 and 2009
included a decrease related to actuarial losses of Ps. 2,578,451 (Ps. 1,333,487, net of deferred taxes) and Ps. 2,210,512 (Ps. 849,682, net of deferred taxes), respectively.

The plan assets to cover pension and other post-retirement benefits totaled Ps. 11,358,647 and Ps. 10,822,273 at December 31, 2008
and 2009, respectively. The Companys fund managers seek to minimize investment risk and accordingly have been keeping the fund investments in cash and cash equivalents and debt instruments at fixed rates.

Our current investment strategy, pension assets of Puerto Rico are allocated with a goal to achieve the following distribution:



|                           |  |

|     cash and equivalents |  | 56.2%

|     equity instruments   |  | 2.5% 

Transactions between entities under common control

Mexican FRS requires any difference between the acquisition cost and the carrying value of net assets acquired in some
qualifying transactions between entities under common control be recognized in shareholders equity as a capital transaction. For U.S. GAAP purposes transactions between entities under common control are also recognized as a capital transaction
but are recorded at the lower of net book value or fair value.

Net gain on sale to affiliate

The Company recognized in its equity income in prior years a gain of Ps. 53,929 (América Movils interest) derived from the
sale of assets by CompUSA to Grupo Telvista. Since both entities are affiliates of América Móvil, this gain was considered a transaction between entities under common control and recognized as additional paid in capital for
US GAAP purposes.

Excess of contributed company over cost

The remaining percentage of América Móvils interest in ATL (formerly AlgarTelecom Leste, S.A.) was contributed to
Telecom Américas in 2002 for an amount of Ps. 4,412,376. Under Mexican FRS, the excess paid over carrying value of ATL was considered as a gain and included under the caption other income, net. For US GAAP purposes since this was
considered as a step acquisition, this excess was considered as negative goodwill and netted with the positive goodwill of the other ATL shares acquired in previous years.

Acquisition of non-controlling interest

Mexican FRS requires that acquisitions of non-controlling interests be treated as a capital transaction. Any difference between the
acquisition cost and the carrying value of the net assets acquired is recognized in shareholders equity. Under US GAAP, in accordance with ASC 805, Business Combinations, effective

##### Table of Contents

January 1, 2009, acquisitions of non-controlling interests are also recognized as a capital transaction. Any difference between the acquisition cost and the carrying value of the net assets
acquired is recognized in shareholders equity. Prior to January 1, 2009, acquisitions of non-controlling interests were accounted for using the purchase method of accounting under US GAAP.

ASC 810, Consolidation, establishes new US GAAP accounting and reporting standards for non-controlling interest in a
subsidiary and for the deconsolidation of a subsidiary. ASC 810 is effective January 1, 2009 and requires retroactive presentation and disclosure of existing non-controlling interests as a component of shareholders equity. ASC 810 also
clarifies that changes in a parents ownership interest in a subsidiary that do not result in deconsolidation are equity transactions if the parent retains its controlling financial interest and requires that a parent recognize a gain or loss
in net income when a subsidiary is deconsolidated. The gain or loss will be measured using the fair value of the non-controlling equity investment on the deconsolidation date.

As of December 31, 2008 and 2009, the reconciliation of shareholders equity included an increase of Ps. 929,459 in each year,
related to acquisition of non-controlling interests in prior years.

Accounting for uncertainty in income taxes

For US GAAP purposes, the Company establishes reserves to remove some or all of the tax benefit of any of its tax positions at the
time management determines that it becomes uncertain based upon one of the following conditions: (1) the tax position is not more likely than not to be sustained, (2) the tax position is more likely than not to be
sustained, but for a lesser amount, or (3) the tax position is more likely than not to be sustained, but not in the financial period in which the tax position was originally taken.

For purposes of evaluating whether or not a tax position is uncertain, (1) management presumes the tax position will be examined by
the relevant taxing authority that has full knowledge of all relevant information, (2) the technical merits of a tax position are derived from authorities such as legislation and statutes, legislative intent, regulations, rulings and case law
and their applicability to the facts and circumstances of the tax position, and (3) each tax position is evaluated without consideration of the possibility of offset or aggregation with other tax positions taken.

A number of years may elapse before a particular uncertain tax position is audited and finally resolved or when a tax assessment is
raised. The number of years subject to tax assessments varies depending on the tax jurisdiction and is generally five years for the countries in which the Company principally operates. The tax benefit that has been previously reserved because of a
failure to meet the more likely than not recognition threshold would be recognized in the Companys income tax expense in the first period when the uncertainty disappears under any one of the following conditions: (1) the tax
position is more likely than not to be sustained, (2) the tax position, amount, and/or timing is ultimately settled through negotiation or litigation, or (3) the statute of limitations for the relevant taxing authority to
examine and challenge the tax position has expired.

The adoption of the provisions with respect to the accounting for
uncertain tax positions in ASC 740, Income Taxes, as of January 1, 2007 did not have a material impact on the Companys financial statements and did not result in a cumulative adjustment to retained earnings at adoption, because all
uncertain tax positions that were not more likely than not to be sustained were reserved in prior years. During the years ended December 31, 2008 and 2009, the Company only recorded additional interest of Ps. 11,942 and Ps. 2,925, respectively.
The Company will continue to recognize interest and penalties on liabilities recorded for unrecognized tax benefits in interest expense.

The deferred tax adjustment included in the net income and shareholders equity reconciliations, also includes the effect of
deferred taxes on all U.S. GAAP adjustments reflected in the reconciliation between Mexican FRS and U.S. GAAP.

Goodwill

Beginning January 1, 2005, due to the adoption of Mexican Bulletin B-7, goodwill is no longer amortized, but rather is subject to
periodic impairment valuations.

For US GAAP purposes, the Company adopted ASC 350, Intangibles  Goodwill and
Other, in 2002. For Mexican FRS purposes goodwill was amortized up to December 31, 2004, thus the Company recognized an increase to US GAAP shareholders equity of Ps. 4,483,032 as of December 31, 2008 and 2009 to reverse the
MFRS accumulated amortization of goodwill, since goodwill is not amortized under US GAAP.

Impairment

When performing impairment tests of goodwill, the computation methodologies under Mexican FRS are different than US GAAP. Under Mexican
FRS, the Company is allowed to evaluate the carrying value of goodwill and other long-lived assets in the aggregate, recording any potential impairment loss first to goodwill and then to the remaining long-lived assets evaluated. Under Mexican FRS,
an impairment loss is recognized whenever the carrying value of these assets exceeds their recoverable value, which is the greater of its net selling price (if it can be readily obtained) and its value in use. These values can be determined through
valuation techniques or, in a more practical manner, through a perpetuity value.

Goodwills net selling price shall be
determined in the same manner that goodwill is obtained in a business acquisition. In this case, the net selling price of the business unit must be determined through the use of market values or through valuation techniques.

The determination of the value in use of goodwill through the determination of perpetuity values is made in two steps. In the first step
the Company must determine the excess of the value in use of the cash generating units assets other than intangible assets with indefinite lives and goodwill, where value in use is the projected discounted cash flows of the cash generating
unit. In the second step, the Company must measure the perpetuity value of the excess value in use of the cash generating unit, which is determined by dividing the average of the excess of the value in use determined in step 1 by the average of the
appropriate discount rates used in the cash projections.

Under US GAAP, separate impairments analyses are performed for
goodwill, indefinite lived intangible assets, and other long-lived assets. ASC 350 requires a two-step process to identify and quantify the amount of impairment loss to be recognized for goodwill. The first step of this test requires the comparison
of the fair value of the reporting unit against its carrying value. The fair value of a reporting unit is the amount at which the unit as a whole could be bought or sold in a current transaction between willing parties. In some instances quoted
market prices in active markets provide the best evidence of fair value and should be used as the basis for the measurement, if available. However, there are instances when the market price of an individual equity security may not be representative
of the reporting units fair value taken as a whole. If fair value of the reporting unit is less than its carrying value, a second step is performed to measure the amount of impairment based on cash flows.

Differences in both the aggregation of amounts within the impairment tests and also the differing valuation techniques can at times
create different results with respect to impairment under Mexican FRS as compared to US GAAP. In the 2008 Mexican FRS consolidated financial statements, the Company recognized an impairment loss of Ps. 527,770 related to goodwill and an impairment
loss of Ps. 212,083 related to intangible assets and property, plant and equipment of its Honduran operations. Under US GAAP, the fair value of the reporting unit was greater than its carrying value, and thus no impairment was recorded.
Therefore, such impairments have been reversed in the US GAAP reconciliations included elsewhere in this Note. For the year ended December 31, 2009, there were no impairment losses recognized for Mexican FRS and US GAAP. For the year
ended December 31, 2007, there was a write-off of TDMA assets related to Brazil of Ps. 2,922,109 that was presented under Mexican FRS in the Other expenses, net caption and for US GAAP purposes was presented as part of
Operating income.

Licenses

During 2006, the Company received a definitive ruling by the Federal Tax and Administrative Court in favor of one of the Companys
subsidiary, which established the following:

i) The consideration paid by Telcel to the Federal Government in
the amount of Ps. 116,422 as initial payment and additional payments of Ps. 1,998,539 for the annual share of gross revenues derived from the 15-year extension (expiring in October 2015) for the concession originally granted by the Ministry of
Communications and Transportation (SCT) in October 2000, was unjustified, since such considerations were determined based on a law that was no longer in force.

ii) Telcel should in fact have made a one-time payment for the granting of the concession, in conformity with the law
applicable at that time. On April 11, 2006, the SCT ordered a one-time modification to the amount of the consideration from Ps. 116,422 to Ps. 2,265,931, for the extension and modification of the concession granted.

Accordingly, under Mexican FRS, the Company adjusted the value of the license to reflect the current status of the asset by recognizing
the value of the concession granted by the Federal Government and its corresponding amortization through April 2006, based on the new value assigned by the SCT, increasing the net investment on such license by Ps. 1,354,070 (Ps. 2,265,931 in
investment less Ps. 838,151 in accumulated amortization less cancellation of original net value of license for Ps. 73,710). The increase in the value of the license of Ps. 2,149,509 was settled with a cash payment of Ps. 150,970 and compensating the
additional payments for the annual share of gross revenues in the amount of Ps. 1,998,539, which resulted a net credit to results of operations of Ps. 1,203,100 included in other income in 2006, based on the adjusted investment value of the license.

Amortization expense for the remaining eight-month period ended December 31, 2006, amounted to Ps. 103,465. The total
effect of the mentioned entries represented a net credit to the income statement for Mexican FRS purposes of Ps. 1,099,635.

For U.S. GAAP, the Company could only capitalize the additional amount paid in cash, as the compensation of the other payments was made
with the same entity and did not generate any cash flows. Furthermore, the amortization expense was not adjusted retrospectively; rather, the new net value of the license under U.S. GAAP, in the amount of Ps. 224,680 is being amortized over the
remaining term of the license.

The U.S. GAAP shareholders equity reconciliations show the reversal of adjustments
recognized under Mexican FRS in the amount of Ps. 1,099,635, (credit of Ps. 1,203,100 less amortization expenses of Ps. 103,465) as of December 31, 2008 and 2009, as well as the related accumulated amortization. The net income reconciliations
include the reversal of the amortization expense not recognized under U.S. GAAP in the amount of Ps. 127,399, Ps. 127,526 and Ps. 127,525 in 2007, 2008 and 2009, respectively.

Accounting for Consideration Given by a Vendor to a Customer

ASC 605-50, Customer Payments and Incentives, addresses the income statement characterization of consideration given by a vendor to
a customer. ASC 605-50 is relevant to the Company particularly with respect to accounting for commissions paid to distributors for the activation of postpaid plans, the commissions that are paid to distributors only if a distributor completes a
specified cumulative level of revenue transactions and commissions paid to distributors when a customer remains with the Company for a specified time period.

Application of ASC 605-50 represented a reclassification for US GAAP purposes of commissions paid to distributors from commercial
and administrative expenses to reductions in operating revenues of Ps. 12,245,020, Ps. 14,942,712 and Ps. 17,121,713 for the years ended December 31, 2007, 2008 and 2009, respectively.

Accounting for Revenue Arrangements with Multiple Deliverables

ASC 605-25, Multiple-Element Arrangements, addresses certain aspects of accounting for sales that involve multiple revenue
generating products and/or services sold under a single contractual agreement. Differences between the Companys revenue recognition for multiple-element arrangements under Mexican FRS as compared to US GAAP are included in the
reconciliation of net income and shareholders equity below.

Effects of Inflation Accounting on the U.S. GAAP Adjustments:

Through December 31, 2007, to determine the net effect on the consolidated financial statements of recognizing the
U.S. GAAP adjustments described above, the effects of applying the Mexican FRS inflation accounting provision (described in Note 2) was recognized on such adjustments. These effects were taken into consideration in the preparation of the U.S. GAAP
reconciliations of net income and shareholders equity.

However, the Company has reversed the re-expression of the
financial information for prior periods, as related to its foreign operations, into constant Mexican Pesos at December 31, 2007, using a weighted-average inflation factor of 1.2607, and re-expressed such period into constant Mexican Pesos at
December 31, 2007 using the Mexican only inflation factor of 1.0376, in order to present its financial statements in the same reporting currency for all periods included in this Note.

Effective January 1, 2008, and as a result of adopting MFRS B-10, Effects of inflation, the Company ceased recognizing the
effects of inflation in its financial statements and considered the re-expressed amounts of all non-monetary items as its carrying basis as of January 1, 2008. The Company has not reconciled the inflation adjustments still included in its
non-monetary items, with one exception for the adjustments in the valuation of plant, property and equipment and related depreciation expense, previously mentioned in this Note.

ASC 820, Fair value measurement:

ASC 820, Fair Value Measurements and Disclosures, define fair value as the exchange price that would be received for an asset or
paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. Additionally, the inputs used to measure fair value
are prioritized based on a three-level hierarchy requires entities to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows:



| |  |  | Level 1  Quoted prices in active markets for identical assets or liabilities.
| | - |  | ------------------------------------------------------------------------------



| |  |  | Level 2- Observable inputs other than quoted priced included in Level 1. We value assets and liabilities included in this level using dealer and broker
quotations, bid prices for similar assets and liabilities in active markets, or other inputs that are observable or can be corroborated by observable market data.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Level 3  Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or
liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs.

In accordance with accounting principles generally accepted in the United States, certain
assets and liabilities are required to be recorded at fair value on a recurring basis. For the Company, the only assets and liabilities that are adjusted to fair value on a recurring basis are the pension plan assets and the derivative financial
instruments.

The following tables summarize fair value measurements and disclosures under ASC 820 as of December 31,
2008 and 2009:

In accordance with ASC 820, it is necessary to provide
information about the fair value of certain financial instruments for which it is practicable to estimate that value. The carrying amounts of cash and cash equivalents, accounts receivable and accounts payable and accrued liabilities approximate
fair values due to the short maturity of these instruments.

The fair value of total debt, excluding capital leases, is
estimated using discounted cash flow analyses based on current borrowing rates offered to the Company for debt of the same remaining maturities and the market value for the senior notes at December 31, 2009 and 2008. As of December 31,
2009, the carrying value of total debt is Ps. 110,909,140 (Ps. 143,486,448 at December 31, 2008) and the fair value is Ps. 112,250,692 (Ps. 137,112,998 at December 31, 2008).

As of December 31, 2008 and 2009, the Company had no financial assets or liabilities requiring Level 3 classification, including
those that have unobservable inputs that are supported by little or no market activity and are significant to the fair value of the assets and liabilities.

In addition to assets and liabilities that are recorded at fair value on a recurring basis,
the Company records assets and liabilities at fair value on a nonrecurring basis as required by accounting principles generally accepted in the United States. Generally, assets are recorded at fair value on a nonrecurring basis as a result of
impairment charges. During the year ended December 31, 2009, there were no changes in carrying value as a result of impairment charges.

Summary

Net income,
operating income and total shareholders equity, adjusted to take into account the significant differences between Mexican FRS and U.S. GAAP, are as follows:

A summary of the most significant new pronouncements in U.S. GAAP that became effective in 2009 or after
and may apply to the Company is as follows:

ASC 810,Consolidation

ASC 810, Consolidation, establishes new accounting and reporting standards for the non-controlling interest in a subsidiary and for
the deconsolidation of a subsidiary. It is effective beginning January 1, 2009, requiring retroactive presentation and disclosure of existing non-controlling interest. ASC 810 clarifies that changes in a parents ownership interest in a
subsidiary that do not result in deconsolidation are equity transactions if the parent retains its controlling financial interest and requires that a parent recognize a gain or loss in net income when a subsidiary is deconsolidated. The gain or loss
will be measured using the fair value of the non-controlling equity investment on the deconsolidation date. This standard includes expanded disclosure requirements regarding the interests of the parent and its non-controlling interest. The adoption
of this new guidance resulted in a retrospective adjustment of the Balance Sheet, Income Statement and Shareholders Equity for the prior years, for presentation and disclosures purposes as follows:

ASC 805,Business
Combinations

In December 2007, the FASB issued Statement of Financial Accounting Standards (SFAS)
No. 141(R), Business Combinations, which was later codified as part of ASC 805. Under the revised standard, costs incurred to effect a business acquisition (i.e., acquisition-related costs) must be recognized separately from the
acquisition. In addition, restructuring costs that the acquirer expected but was not obligated to incur, which include changes to benefit plans, were recognized as if they were a liability assumed at the acquisition date; however, the acquirer is
now required to recognize those costs separately from the business combination. ASC 805 is effective for all business acquisitions subsequent to January 1, 2009. The adoption of this standard did not have a material impact on the Companys
financial statements, in part, because it had no material acquisitions in 2009.

ASC 815,Derivatives and Hedging

In March 2008, the FASB issued SFAS No. 161, Disclosures about Derivative Instruments and Hedging Activities, an
amendment of FASB Statement No. 133 (FAS 161), which was later codified as a component of ASC 815. ASC 815 requires enhanced disclosures about an entitys derivatives and hedging activities to improve the transparency of
financial reporting to include (a) how and why an entity uses derivative instruments; (b) how derivative instruments and related hedged items are accounted for under ASC 815 and its related interpretations; and (c) how derivative
instruments and related hedged items affect an entitys financial position, financial performance, and cash flows. ASC 815 is effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008.
The effect of adoption of this new guidance was included in the disclosures as presented herein.

Determination of the Useful Life of Intangible Assets(FAS 142-3)

In April 2008, the FASB issued FASB Staff Position FAS 142-3, Determination of the Useful Life of Intangible
Assets (FSP FAS 142-3), which was codified as a component of ASC 350, Intangibles  Goodwill and Other, and amended the factors that should be considered in developing renewal or extension assumptions used to determine the useful
life of a recognized intangible asset. ASC 350 is effective for financial statements issued for fiscal years beginning after December 15, 2008. The adoption of this new guidance did not have any impact on the Companys financial position
or results of operations.

ASC 820,Fair Value Measurements and Disclosures

In October 2008, the FASB issued FASB Staff Position 157-3, which was later codified as a component of ASC 820, Fair Value Measurements
and Disclosures, which establishes a framework for measuring fair value for all financial assets and liabilities and for non-financial assets and liabilities recognized or disclosed at fair value on a recurring basis (at least annually). For all
other assets and liabilities, these requirements became effective on January 1, 2009. The adoption of ASC 820 resulted in additional disclosures as presented herein.

ASC 715,Compensation  Retirement Benefits

In December 2008, the FASB issued FASB Staff Position FAS 132(R), which was later codified as a component of ASC 715, Compensation
 Retirement Benefits. This ASC requires plan sponsors to provide improved disclosures about plan assets, including categories of plan assets, nature and amount of concentrations of risk and disclosure about fair value measurements of plan
assets, similar to those required by ASC 820. ASC 715 is effective for fiscal years ending after December 2009. This ASC increased the amount of disclosures for plan assets in the Companys 2009 financial statements.

EITF 08-1,Revenue Arrangements with Multiple Deliverables

(codified in ASC 605-25,Multiple-Element Arrangements)

On September 23, 2009, the FASB ratified Emerging Issues Task Force Issue No. 08-1, Revenue Arrangements with Multiple
Deliverables (EITF 08-1). EITF 08-1 updates the guidance pertaining to multiple-element revenue arrangements currently included in ASC 605-25, which originated primarily from EITF 00-21, also titled Revenue Arrangements with Multiple
Deliverables. This new guidance will be effective for annual reporting periods beginning January 1, 2011 for calendar-year entities. The Company is currently evaluating the impact of this new guidance on its financial position, results of
operations, cash flows, and disclosures.

ASC 350,Intangibles  Goodwill & Other

In November 2008, the FASB ratified ASC 350, Intangibles  Goodwill & Other. ASC 350 requires that a defensive
intangible asset be accounted for as a separate unit of accounting and assigned a useful life which reflects the entitys consumption of the expected benefits related to that asset. A defensive intangible asset is an acquired intangible asset
which the acquirer does not intend to actively use, but intends to hold to prevent others from obtaining access to the asset, excluding intangible assets that are used in research and development. An entitys benefit from holding a defensive
intangible asset is the direct and indirect cash flows resulting from the entity preventing others from realizing any value from the intangible assets. The period over which a defensive asset diminishes in fair value can be used as a proxy for the
entitys consumption of the expected benefits related to the asset. This guidance is effective for defensive intangible assets acquired on or after January 1, 2009. The adoption of this new guidance did not have any impact on the
Companys financial position or results of operations.

ASC 855,Subsequent Events

In May 2009, the FASB issued ASC 855, Subsequent Events. ASC 855 establishes general standards of accounting for and disclosure of
events that occur after the balance sheet date but before financial statements are

issued or are available to be issued. In particular, ASC 855 sets forth (1) the period after the balance sheet date during which management of a reporting entity should evaluate events or
transactions that may occur for potential recognition or disclosure in the financial statements, (2) the circumstances under which an entity should recognize events or transactions occurring after the balance sheet date in its financial
statements and (3) the disclosures that an entity should make about events or transactions that occurred after the balance sheet date. In accordance with ASC 855, an entity should apply the requirements to annual financial periods ending after
June 15, 2009. The adoption of this new guidance did not have any impact on the Companys financial position or results of operations.

ASC 810,Consolidation

In December 2007, the FASB issued ASC 810, Consolidation, as amended by SFAS 160, which establishes new accounting and reporting
standards for the non-controlling interest in a subsidiary and for the deconsolidation of a subsidiary, effective beginning January 1, 2009, requiring retroactive presentation and disclosure of existing non-controlling interest. ASC 810
clarifies that changes in a parents ownership interest in a subsidiary that do not result in deconsolidation are equity transactions if the parent retains its controlling financial interest and requires that a parent recognize a gain or loss
in net income when a subsidiary is deconsolidated. The gain or loss will be measured using the fair value of the non-controlling equity investment on the deconsolidation date. This standard includes expanded disclosure requirements regarding the
interests of the parent and its non-controlling interest. The adoption of this new guidance resulted in a retrospective adjustment of the Balance Sheet, Income Statement and Shareholders Equity for the prior years, for presentation and
disclosures purposes as described above in this Note.

Guarantor US GAAP reconciliation of net income and shareholders equity

As discussed at the beginning of Note 21, the following reconciliation to US GAAP does not include the reversal of the adjustments to
the financial statements for the effects of inflation required under Mexican FRS (Bulletin B-10).

Summary

The principal differences between Mexican FRS and U.S. GAAP, as they relate to the consolidating financial statements of the Company, and
those of the Guarantor, are basically the same as those described in Note 21, except for the adjustments applied directly to the sub-holdings companies, such as the non-amortization of goodwill, non-controlling interest, gains or losses on sales to
affiliates and the reversal of the impairment recognized under Mexican FRS.

Net income and total shareholders equity,
adjusted to take into account the material differences between Mexican FRS and U.S. GAAP, are as follows:
