amount does not include Notes authenticated and delivered upon registration of transfer of, in exchange for, or in lieu of, other Securities of such series pursuant to Sections 304, 305, 306, 906 or 1105 of the Base Indenture), which amount shall be
specified in the Company Order for the authentication and delivery of Notes pursuant to Section 303 of the Base Indenture. The principal of the Notes shall be due and payable at their Stated Maturity. 

(b) The Company may, from time to time and without the consent of the Holders, issue additional notes on terms and conditions identical
to those of the Notes (except for issue date, issue price and the date from which interest shall accrue and, if applicable, first be paid), which additional notes shall increase the aggregate principal amount of, and shall be consolidated and form a
single series with, the Notes. 
 (c) The Stated Maturity of the Notes shall be October 27, 2026. The Notes shall bear
interest at the rate of 5.000% per annum from October 27, 2011 or from the most recent Interest Payment Date to which interest has been paid or duly provided for, as the case may be, payable annually in arrears on

  
 3 

 
October 27, commencing on October 27, 2012, until the principal thereof is paid or made available for payment on or prior to the Stated Maturity of the Notes; provided, however,
that any amount of interest on any Note which is overdue shall bear interest (to the extent that payment thereof shall be legally enforceable) at the rate per annum then borne by such Note from the date such amount is due to the day it is paid or
made available for payment, and such overdue interest shall be paid as provided in Section 306 of the Base Indenture. 

(d) If, prior to October 27, 2026, the United Kingdom adopts the euro as its lawful currency in accordance with the Treaty
Establishing the European Community, as amended from time to time, the Notes will be re-denominated into euro, and the regulations of the European Commission relating to the euro shall apply to the Notes as so re-denominated. The circumstances and
consequences described in this Section 201(d) will not entitle the Company, the Trustee or any Holder of the Notes to redeem early, rescind or receive notice relating to the Notes, repudiate the terms of the Notes, the Base Indenture or this
Eleventh Supplemental Indenture, raise any defense, request any compensation or make any claim, nor will these circumstances and consequences affect any of the Company’s other obligations under the Notes, the Base Indenture or this Eleventh
Supplemental Indenture. 
 Section 202. Denominations. 
 The Notes shall be issued only in denominations of £100,000 and integral multiples of £1,000 in excess thereof. 
 Section 203. Computation of Interest. 
 Interest on the Notes shall be
computed on the basis of the actual number of days elapsed in an interest period divided by 365 or, in the case of an Interest Payment Date falling in a leap year, 366. 
 Section 204. Forms Generally. 
 The Notes shall be in
substantially the forms set forth in this Section 204, with such appropriate insertions, omissions, substitutions and other variations as are required or permitted by this Eleventh Supplemental Indenture, and may have such letters, numbers or
other marks of identification and such legends or endorsements placed thereon as may be required to comply with the rules of any securities exchange or as may, consistently herewith, be determined by the officers executing such Notes, as evidenced
by their execution thereof; provided that if any Notes are issued in certificated and not global form, such Notes shall be in substantially the form set forth in this Section 204, but shall not contain the legends relating to Global
Notes or the “Schedule of Increases or Decreases in Global Note.” 
 Upon their original issuance, the Notes shall be
issued in the form of one or more Global Notes in definitive, fully registered form, without coupons, substantially in the form set forth in this Section 204. Such Global Notes shall be registered in the name of the Common Depositary, or its
nominee, and deposited with the Common Depositary, duly executed by the Company and authenticated by the Trustee as hereinafter provided. The aggregate amount of any Global Notes may from time to time be increased or decreased by adjustments made on

 América Móvil, S.A.B. de C.V. (the “Company,” which term includes any successor
Person under the Indenture hereinafter referred to), a sociedad anónima bursátil de capital variable organized and existing under the laws of the United Mexican States (“Mexico”), for value received, hereby promises to
pay to The Bank of New York Depository (Nominees) Limited, or registered assigns, as common depositary for Clearstream Banking, société anonyme and Euroclear Bank, S.A./N.V., the principal sum of Five Hundred Million pounds sterling
(or the equivalent amount of euro, if the United Kingdom adopts the euro), as revised by the Schedule of Increases and Decreases in Global Note attached hereto on October 27, 2026 (unless earlier redeemed, in which case, on the applicable
Redemption Date) and to pay interest thereon from October 27, 2011 or from the most recent Interest Payment Date to which interest has been paid or duly provided for, as the case may be, annually in arrears on October 27 of each year,
commencing on October 27, 2012 at the rate of 5.000% per annum, until the principal hereof is paid or made available for payment; provided that any principal of, and any premium and interest on, this Note which is overdue shall bear
interest (to the extent that payment thereof shall be legally enforceable) at the rate per annum then borne by this Note from the date such amount is due to but not including the day it is paid or made available for payment, and such overdue
interest shall be paid as provided in Section 306 of the Base Indenture. 
 Interest on the Notes shall be calculated on
the basis of a 365-day year or, in the case of an Interest Payment Date falling in a leap year, a 366-day year, and the actual number of days elapsed from and including the last Interest Payment Date (or, with respect to interest payable on the
first Interest Payment Date, from the issue date of this Note) to but excluding the Interest Payment Date on which the interest payment falls due. 
 The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date shall, as provided in the Indenture, be paid to the Person in whose name this Note (or one or more
Predecessor Notes) is registered at the close of business on the Regular Record Date for such interest, which shall be the October 15 (whether or not a Business Day) next preceding such Interest Payment Date. Any such interest not so punctually
paid or duly provided for on any Interest Payment Date shall forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this Note (or one or more Predecessor Notes) is registered at the
close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of this Note not less than 10 days prior to such Special Record Date, or be paid at any time
in any other lawful manner not inconsistent with the requirements of 

  
 5 

 any securities exchange on which this Note may be listed, and upon such notice as may be required by such
exchange, all as more fully provided in the Indenture. 
 Payment of the principal of, and premium, if any, and interest on,
this Note shall be made at the office of the Trustee or agency of the Company in the Borough of Manhattan, The City of New York, New York and at the Specified London Office of the Paying Agent and, if and for so long as the Notes are admitted to
listing on the Official List of the Luxembourg Stock Exchange and trading on the Euro MTF, at the office of the Luxembourg Paying Agent, in each case maintained for such purpose and at any other office or agency maintained by the Company for such
purpose, in pounds sterling (or euro, if the United Kingdom adopts the euro) against surrender of this Note in the case of any payment due at the Maturity of the principal thereof (other than any payment of interest that first becomes payable on a
day other than an Interest Payment Date); provided, however, that at the option of the Company, payment of interest may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Security
Register. [If the Note is a Global Note, then insert — Notwithstanding the foregoing, payment of any amount payable in respect of a Global Note shall be made in accordance with the Applicable Procedures of the Depositary.] 

Reference is hereby made to the further provisions of this Note set forth on the reverse hereof, which further provisions shall for all
purposes have the same effect as if set forth at this place. 
 Unless the certificate of authentication hereon has been
executed by the Trustee referred to on the reverse hereof by manual signature, this Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose. 

IN WITNESS WHEREOF, the Company has caused this instrument to be duly executed.

 (b) Form of Reverse of Note. 

This Note is one of a duly authorized issue of securities of the Company (the “Notes”), issued under an Indenture, dated as of
September 30, 2009 (the “2009 Indenture”), among the Company, Radiomóvil Dipsa, S.A. de C.V., a sociedad anónima de capital variable organized and existing under the laws of Mexico (“Telcel,” which term
includes any successor Person under the Indenture), The Bank of New York Mellon, as Trustee (the “Trustee,” which term includes any successor trustee under the Indenture), Security Registrar, Paying Agent and Transfer Agent, as amended and
supplemented by the 

  
 6 

 
Ninth Supplemental Indenture dated as of October 27, 2011 (the “Ninth Supplemental Indenture” and, together with the 2009 Indenture, the “Base Indenture”), among the
Company, Telcel and the Trustee, as further supplemented by the Eleventh Supplemental Indenture dated as of October 27, 2011 (the “Eleventh Supplemental Indenture” and, together with the Base Indenture, the “Indenture”)
among the Company, the Trustee and The Bank of New York Mellon (Luxembourg) S.A., as Luxembourg Paying Agent and Luxembourg Transfer Agent and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights,
duties and immunities thereunder of the Company, the Trustee and the Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered. The terms, conditions and provisions of this Note are those stated in
the Indenture (including those made a part of the Indenture by reference to the Trust Indenture Act) and those set forth in this Note. This Note is one of the series designated on the face hereof. 

Additional notes on terms and conditions identical to those of this Note (except for issue date, issue price and the date from which
interest shall accrue and, if applicable, first be paid) may be issued by the Company without the consent of the Holders of the Notes. The amount evidenced by such additional Notes shall increase the aggregate principal amount of, and shall be
consolidated and form a single series with, the Notes, in which case the Schedule of Increases and Decreases in Global Note attached hereto will be correspondingly adjusted. 
 If, prior to October 27, 2026, the United Kingdom adopts the euro as its lawful currency in accordance with the Treaty Establishing the European Community, as amended from time to time, this Note
will be re-denominated into euro, and the regulations of the European Commission relating to the euro shall apply to this Note as so re-denominated. The circumstances and consequences described in this paragraph will not entitle the Company, the
Trustee or any Holder of this Note to redeem early, rescind or receive notice relating to this Note, repudiate the terms of this Note or the Indenture, raise any defense, request any compensation or make any claim, nor will these circumstances and
consequences affect any of the Company’s other obligations under this Note or the Indenture. 
 In any case where any
Interest Payment Date, Redemption Date or Stated Maturity of any Note shall not be a Business Day, then (notwithstanding any other provision of the Indenture or of the Notes) payment of principal and premium, if any, or interest need not be made on
such date, but may be made on the next succeeding Business Day with the same force and effect as if made on the Interest Payment Date, Redemption Date or at the Stated Maturity, as the case may be; provided that no interest shall accrue for
the period from and after such Interest Payment Date, Redemption Date or Stated Maturity, as the case may be. 
 In the event of
redemption of this Note in part only, a new Note or Notes of this series and of like tenor for the unredeemed portion hereof shall be issued in the name of the Holder hereof upon the cancellation hereof. 

If an Event of Default with respect to Notes shall occur and be continuing, the principal of all of the Notes may be declared due and
payable in the manner and with the effect provided in the Indenture. 
 All payments of principal, premium, if any, and interest
in respect of the Notes shall be made after withholding or deduction for any present or future taxes, duties, assessments or governmental charges of whatever nature imposed, levied, collected, withheld or assessed by or on behalf of Mexico or any
authority therein or thereof having power to tax (“Mexican Taxes”). In the event of any withholding or deduction for any Mexican Taxes, the Company shall pay such additional amounts (“Additional Amounts”) as will result in
receipt by the Holders of Notes on the respective due dates of such amounts as 

  
 7 

 
would have been received by them had no such withholding or deduction (including for any Mexican Taxes payable in respect of Additional Amounts) been required, except that no such Additional
Amounts shall be payable with respect to any payment on a Note to the extent: 
 (i) that any such taxes,
duties, assessments or other governmental charges are imposed solely because of (A) a connection between the Holder and Mexico other than the ownership or holding of such Note and the mere receipt of payments with respect to such Note or
(B) failure by the Holder or any other Person to comply with any certification, identification or other reporting requirement concerning the nationality, residence, identity or connection with Mexico of the Holder or any beneficial owner of
such Note if compliance is required by law, regulation or by an applicable income tax treaty to which Mexico is a party, as a precondition to exemption from, or reduction in the rate of, the tax, assessment or other governmental charge and we have
given the Holders at least 30 days’ notice prior to the first payment date with respect to which such certification, identification or reporting requirement is required to the effect that Holders will be required to provide such information and
identification; 
 (ii) of any such taxes, duties, assessments or other governmental charges with respect to
such Note presented for payment more than 15 days after the date on which such payment became due and payable or the date on which payment thereof is duly provided for and notice thereof given to Holders, whichever occurs later, except to the extent
that the Holder of such Note would have been entitled to such Additional Amounts on presenting such Note for payment on any date during such 15-day period; 
 (iii) of estate, inheritance, gift or other similar taxes, assessments or other governmental charge imposed with respect to such Note; 

(iv) of any tax, duty, assessment or other governmental charge payable otherwise than by deduction or withholding from
payments on such Note; 
 (v) of any payment on such Note to a Holder who is a fiduciary or partnership or a
person other than the sole beneficial owner of any such payment, to the extent that a beneficiary or settlor with respect to such fiduciary, a member of such a partnership or the beneficial owner of such payment would not have been entitled to the
Additional Amounts had such beneficiary, settlor, member or beneficial owner been the Holder of such Note; 

(vi) of any tax, duty, assessment or other governmental charge imposed on a payment to an individual and required to be
made pursuant to European Council Directive 2003/48/EC on the taxation of savings income or any other directive implementing the conclusions of the ECOFIN Council meetings of November 26 and 27, 2000, December 13, 2001, and
January 21, 2003, or any law or agreement implementing or complying with, or introduced in order to conform to, such a directive; and 
 (vii) any combination of the items in Clauses (i) through (vi) above. 

For purposes of the provisions described in Clause (i) above, the term “Holder” of any Note means the direct nominee of
any beneficial owner of such Note, which holds such beneficial owner’s interest in such Note. Notwithstanding the foregoing, the limitations on the Company’s obligation to pay Additional Amounts set forth in Clause (i)(B) above shall not
apply if (a) the provision of information, documentation or other evidence described in such Clause (i)(B) would be materially more onerous, in form, in procedure or in the substance of information disclosed, to a Holder or beneficial

  
 8 

 
owner of a Note (taking into account any relevant differences between U.S. and Mexican law, regulation or administrative practice) than comparable information or other reporting requirements
imposed under U.S. tax law (including the United States—Mexico Income Tax Treaty), regulations (including proposed regulations) and administrative practice or (b) Rule I.3.17.11 (or any successor provision) is in effect, unless the
provision of the information, documentation or other evidence described in such Clause (i)(B) is expressly required by statute, regulation, rule or administrative practice in order to apply Rule I.3.17.11 (or any successor provision) and the Company
cannot obtain such information, documentation or other evidence on its own through reasonable diligence and the Company otherwise would meet the requirements for application of Rule I.3.17.11 (or any successor provision). In addition, such Clause
(i)(B) shall not be construed to require that a non-Mexican pension or retirement fund or a non-Mexican financial institution or any other Person register with the Ministry of Finance and Public Credit for the purpose of establishing eligibility for
an exemption from or reduction of Mexican withholding tax. 
 The Company shall provide the Trustee with the constancia
or other relevant documentation, if any (which may consist of certified copies of such documentation), satisfactory to the Trustee evidencing the payment of Mexican Taxes in respect of which the Company has paid any Additional Amounts. Copies of
such documentation shall be made available to the Holders of the Notes or any Paying Agent, as applicable, upon request therefor. 
 The Company shall pay all stamp, issue, registration, documentary or other similar duties, if any, which may be imposed by Mexico or any governmental entity or political subdivision therein or thereof, or
any taxing authority of or in any of the foregoing, with respect to the Indenture or the issuance of the Notes. 
 All
references herein and in the Indenture to principal, premium, if any, interest or any other amount payable in respect of any Note shall be deemed to include all Additional Amounts, if any, payable in respect of such principal, premium, interest or
other amount payable, unless the context otherwise requires, and express mention of the payment of Additional Amounts in any provision hereof shall not be construed as excluding reference to Additional Amounts in those provisions hereof where such
express mention is not made. 
 In the event that Additional Amounts actually paid with respect to the Notes pursuant to the
preceding paragraphs are based on rates of deduction or withholding of withholding taxes in excess of the appropriate rate applicable to the Holder of such Notes, and, as a result thereof such Holder is entitled to make claim for a refund or credit
of such excess from the authority imposing such withholding tax, then such Holder shall, by accepting such Notes, be deemed to have assigned and transferred all right, title, and interest to any such claim for a refund or credit of such excess to
the Company. However, by making such assignment, the Holder makes no representation or warranty that the Company will be entitled to receive such claim for a refund or credit and incurs no other obligation with respect thereto. 

All references herein and in the Indenture to principal in respect of any Note shall be deemed to mean and include any Redemption Price
payable in respect of such Note pursuant to any redemption right hereunder (and all such references to the Stated Maturity of the principal in respect of any Note shall be deemed to mean and include the Redemption Date with respect to any such
Redemption Price), and all such references to principal, premium, interest or Additional Amounts shall be deemed to mean and include any amount payable in respect hereof pursuant to Section 1009 of the Base Indenture. 

The Company may, at its option, redeem the Notes upon not less than 30 nor more than 60 days’ notice, at any time and, only in the
case of clause (ii) below, from time to time: 

  
 9 

 (i) in whole but not in part, at a Redemption Price equal to the sum of
(A) 100% of the principal amount of the Notes being redeemed, (B) accrued and unpaid interest thereon to the Redemption Date and (C) any Additional Amounts which would otherwise be payable thereon up to but not including the
Redemption Date, solely if, as a result of any amendment to, or change in, the laws (or any rules or regulations thereunder) of Mexico or any political subdivision or taxing authority thereof or therein affecting taxation or any amendment to or
change in an official interpretation or application of such laws, rules or regulations, which amendment to or change in such laws, rules or regulations becomes effective on or after October 27, 2011, the Company would be obligated, after making
reasonable endeavors to avoid such requirement, to pay Additional Amounts in excess of the Additional Amounts that the Company would be obligated to pay if payments made on the Notes were subject to withholding or deduction of Mexican Taxes at the
rate of 4.9%; provided, however, that (1) no notice of redemption pursuant to this clause (i) may be given earlier than 90 days prior to the earliest date on which the Company would be obligated to pay such Additional Amounts if a
payment on the Notes were then due and (2) at the time such notice of redemption is given, the Company’s obligation to pay such Additional Amounts remains in effect; and 

(ii) in whole or in part, at a Redemption Price equal to the greater of (1) 100% of the outstanding principal amount
of the Notes being redeemed and (2) the sum of the present values of the remaining scheduled payments of principal and interest thereon (exclusive of interest accrued to the Redemption Date) discounted to the Redemption Date on an annual basis
(calculated using a 365-day year or a 366-day year, as applicable, and the actual number of days elapsed) at the Sterling Benchmark Rate plus 44 basis points, plus, in the case of (1) and (2), accrued and unpaid interest on the principal amount
of such Notes to but not including the Redemption Date. 
 For purposes of clause (ii) above, the following terms shall
have the specified meanings: 
 “Sterling Benchmark Rate” means, with respect to any Redemption Date, the rate per
annum equal to the annual equivalent yield to maturity or interpolated maturity of the Comparable Sterling Benchmark Issue, assuming a price for the Comparable Sterling Benchmark Issue (expressed as a percentage of its principal amount) equal to the
Comparable Sterling Benchmark Price for such Redemption Date. 
 “Comparable Sterling Benchmark Issue” means the U.K.
Government security or securities selected by an Independent Sterling Investment Banker as having an actual or interpolated maturity comparable to the remaining term of the Notes to be redeemed that would be utilized, at the time of selection and in
accordance with customary financial practice, in pricing new issues of sterling-denominated corporate debt securities of a comparable maturity to the remaining term of such Notes. 

“Comparable Sterling Benchmark Price” means, with respect to any Redemption Date, (i) the average of the Sterling
Reference Dealer Quotations for such Redemption Date, after excluding the highest and lowest such Sterling Reference Dealer Quotations or (ii) if the Trustee obtains fewer than four such Sterling Reference Dealer Quotations, the average of all
such quotations. 
 “Independent Sterling Investment Banker” means one of the Sterling Reference Dealers appointed by
the Company. 

  
 10 

 “Sterling Reference Dealer” means (i) each of Deutsche Bank AG, London Branch
and HSBC Bank plc or their affiliates which are primary securities dealers in securities of the U.K. Government, and their respective successors; provided, that if any of the foregoing shall cease to be a primary government securities dealer
of securities of the U.K. Government (a “Primary Sterling Dealer”), the Company will substitute therefor another Primary Sterling Dealer and (ii) any other three Primary Sterling Dealers selected by the Company. 

“Sterling Reference Dealer Quotation” means, with respect to each Sterling Reference Dealer and any Redemption Date, the
average, as determined by the Trustee, of the bid and asked prices for the Comparable Sterling Benchmark Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by such Sterling Reference Dealer at
11:00 a.m. (Central European Time) on the third business day preceding such Redemption Date. 
 The Indenture permits, with
certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company, on the one hand, and the rights of the Holders of the Notes, on the other hand, at any time by the Company and the
Trustee with the consent of the Holders of a majority in principal amount of the Notes at the time Outstanding. The Indenture also contains provisions (1) permitting the Holders of a majority in principal amount of the Notes at the time
Outstanding, on behalf of the Holders of all Notes, to waive compliance by the Company with certain provisions of the Indenture and (2) permitting the Holders of a majority in principal amount of the Notes at the time Outstanding, on behalf of
the Holders of all Notes, to waive certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and
of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note. 
 As provided in and subject to the provisions of the Indenture, the Holder of this Note shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a
receiver or trustee, or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Notes, the Holders of not less than 25% in principal amount of
the Notes at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee indemnity reasonably satisfactory to it, and the Trustee shall not have
received from the Holders of a majority in principal amount of Notes at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and
offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Note for the enforcement of any payment of principal hereof or premium, if any, and/or interest hereon on or after the respective due dates expressed
herein. 
 No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the
obligation of the Company, which is absolute and unconditional, to pay the principal of and premium, if any, and interest on this Note at the times, place and rate, and in the coin or currency, herein prescribed. 

As provided in the Indenture, and subject to certain limitations therein set forth (including, without limitation, the restrictions on
transfer under Section 304 of the Indenture), the transfer of this Note is registrable in the Security Register, upon surrender of this Note for registration of transfer at the office of the Trustee or agency of the Company in any place where
the principal of and any premium and interest on this Note are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder

  
 11 

 
hereof or his attorney duly authorized in writing, and thereupon one or more new Notes of this series and of like tenor, of authorized denominations and for the same aggregate principal amount,
shall be issued to the designated transferee or transferees. 
 The Notes are issuable only in registered form without coupons
in denominations of £100,000 and integral multiples of £1,000 in excess thereof. As provided in the Indenture, and subject to certain limitations therein set forth, Notes are exchangeable for a like aggregate principal amount of Notes of
like tenor of a different authorized denomination, as requested by the Holder surrendering the same. 
 No service charge shall
be made for any such registration of transfer or exchange, but the Company or the Trustee may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. 

Prior to due presentment of this Note for registration of transfer, the Company, the Trustee and any agent of the Company or of the
Trustee may treat the Person in whose name this Note is registered as the owner hereof for all purposes, whether or not this Note is overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

 [If the Note is a Global Note, then insert—This Note is a Global Note and is subject to the provisions of the
Indenture relating to Global Notes, including the limitations in Section 304 of the Indenture on transfers and exchanges of Global Notes.] 
 This Note and the Indenture shall be governed by, and construed in accordance with, the law of the State of New York.

(a) Section 304(2) of the Base Indenture is hereby amended and restated with respect to the Notes as follows: 

“(2) Notwithstanding any other provision in this Indenture or the Notes, no Global Note may be exchanged in whole or
in part for Notes registered, and no transfer of a Global Note in whole or in part may be registered, in the name of any Person other than the Depositary or a nominee thereof unless (A) the Depositary has notified the Company that it is

request for certificates has been made by the Company upon 60 days’ prior written notice given to the Trustee in accordance with the Applicable Procedures of the Depositary and a copy of such notice has been received by the Company from the
Trustee. Any Global Note exchanged pursuant to Clause (A) above shall be so exchanged in whole and not in part and any Global Note exchanged pursuant to Clause (B) or (C) above may be exchanged in whole or from time to time in part as
directed by the Depositary. Any Note issued in exchange for a Global Note or any portion thereof shall be a Global Note; provided that any such Note so issued that is registered in the name of a Person other than the Depositary or a nominee
thereof shall not be a Global Note.” 
 (b) Section 304(5) of the Base Indenture is hereby amended and restated with
respect to the Notes as follows: 

  
 13 

 “(5) None of the Depositary or any members of, or participants in, the
Depositary (“Agent Members”), or any Person on whose behalf Agent Members may act, shall have any rights under this Indenture with respect to any Global Note, or under any Global Note, and the Depositary or such nominee, as the case may
be, may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and holder of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the
Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or such nominee, as the case may be, or impair, as between the Depositary, its Agent Members
and any other person on whose behalf an Agent Member may act, the operation of customary practices of such Persons governing the exercise of the rights of a holder of any Note.” 
 Section 207. Maintenance of Office or Agency 
 (a) With respect to any Notes

Indenture. 
 (b) If and for so long as the Notes are admitted to listing on the Official List of the Luxembourg Stock Exchange

 América Móvil, S.A.B. de C.V. (the “Company,” which term includes any successor
Person under the Indenture hereinafter referred to), a sociedad anónima bursátil de capital variable organized and existing under the laws of the United Mexican States (“Mexico”), for value received, hereby promises to
pay to The Bank of New York Depository (Nominees) Limited, or registered assigns, as common depositary for Clearstream Banking, société anonyme and Euroclear Bank, S.A./N.V., the principal sum of One Billion euro (or such other lawful
currency of the member states of the European Monetary Union that have adopted or that will adopt the single currency in accordance with the Treaty Establishing the European Community, as amended by the Treaty on European Union, as at the time of
payment shall be legal tender for the payment of public and private debts), as revised by the Schedule of Increases and Decreases in Global Note attached hereto on October 25, 2019 (unless earlier redeemed, in which case, on the applicable
Redemption Date) and to pay interest thereon from October 27, 2011 or from the most recent Interest Payment Date to which interest has been paid or duly provided for, as the case may be, annually in arrears on October 25 of each year,
commencing on October 25, 2012 at the rate of 4.125% per annum, until the principal hereof is paid or made available for payment; provided that any principal of, and any premium and interest on, this Note which is overdue shall bear
interest (to the extent that payment thereof shall be legally enforceable) at the rate per annum then borne by this Note from the date such amount is due to but not including the day it is paid or made available for payment, and such overdue
interest shall be paid as provided in Section 306 of the Base Indenture. 
 Interest on the Notes shall be calculated on
the basis of a 365-day year or, in the case of an Interest Payment Date falling in a leap year, a 366-day year, and the actual number of days elapsed from and including the last Interest Payment Date (or, with respect to interest payable on the
first Interest Payment Date, from the issue date of this Note) to but excluding the Interest Payment Date on which the interest payment falls due. 
 The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date shall, as provided in the Indenture, be paid to the Person in whose name this Note (or one or more
Predecessor Notes) is registered at the close of business on the Regular Record Date for such interest, which shall be the October 15 (whether or not a Business Day) next preceding such Interest Payment Date. Any such interest not so punctually
paid or duly provided for on any Interest Payment Date shall forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this Note (or one or more Predecessor Notes) is registered at the
close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of this Note not less than 10 days prior to such Special Record Date, or be paid at any time
in any other lawful manner not inconsistent with the requirements of 

 
any securities exchange on which this Note may be listed, and upon such notice as may be required by such exchange, all as more fully provided in the Indenture. 

Payment of the principal of, and premium, if any, and interest on, this Note shall be made at the office of the Trustee or agency of the
Company in the Borough of Manhattan, The City of New York, New York and at the Specified London Office of the Paying Agent and, if and for so long as the Notes are admitted to listing on the Official List of the Luxembourg Stock Exchange and trading
on the Euro MTF, at the office of the Luxembourg Paying Agent, in each case maintained for such purpose and at any other office or agency maintained by the Company for such purpose, in euro (or such other lawful currency of the member states of the
European Monetary Union that have adopted or that will adopt the single currency in accordance with the Treaty Establishing the European Community, as amended by the Treaty on European Union, as at the time of payment shall be legal tender for the
payment of public and private debts) against surrender of this Note in the case of any payment due at the Maturity of the principal thereof (other than any payment of interest that first becomes payable on a day other than an Interest Payment Date);
provided, however, that at the option of the Company, payment of interest may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register. Notwithstanding the foregoing, payment
of any amount payable in respect of a Global Note shall be made in accordance with the Applicable Procedures of the Depositary. 

Reference is hereby made to the further provisions of this Note set forth on the reverse hereof, which further provisions shall for all
purposes have the same effect as if set forth at this place. 
 Unless the certificate of authentication hereon has been
executed by the Trustee referred to on the reverse hereof by manual signature, this Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

 [REVERSE OF NOTE] 
 This Note is one of a duly authorized issue of securities of the Company (the “Notes”), issued under an Indenture, dated as of September 30, 2009 (the “2009 Indenture”), among the
Company, Radiomóvil Dipsa, S.A. de C.V., a sociedad anónima de capital variable organized and existing under the laws of Mexico (“Telcel,” which term includes any successor Person under the Indenture), and The Bank of
New York Mellon, as Trustee (the “Trustee,” which term includes any successor trustee under the Indenture), Security Registrar, Paying Agent and Transfer Agent, as amended and supplemented by the Ninth Supplemental Indenture dated as of
October 27, 2011 (the “Ninth Supplemental Indenture” and, together with the 2009 Indenture, the “Base Indenture”), among the Company, Telcel and the Trustee, as further supplemented by the Tenth Supplemental Indenture dated
as of October 27, 2011 (the “Tenth Supplemental Indenture” and, together with the Base Indenture, the “Indenture”) among the Company, the Trustee and The Bank of New York Mellon (Luxembourg) S.A., as Luxembourg Paying Agent
and Luxembourg Transfer Agent and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Notes and of the terms
upon which the Notes are, and are to be, authenticated and delivered. The terms, conditions and provisions of this Note are those stated in the Indenture (including those made a part of the Indenture by reference to the Trust Indenture Act) and
those set forth in this Note. This Note is one of the series designated on the face hereof. 
 Additional notes on terms and
conditions identical to those of this Note (except for issue date, issue price and the date from which interest shall accrue and, if applicable, first be paid) may be issued by the Company without the consent of the Holders of the Notes. The amount
evidenced by such additional Notes shall increase the aggregate principal amount of, and shall be consolidated and form a single series with, the Notes, in which case the Schedule of Increases and Decreases in Global Note attached hereto will be
correspondingly adjusted. 
 In any case where any Interest Payment Date, Redemption Date or Stated Maturity of any Note shall
not be a Business Day, then (notwithstanding any other provision of the Indenture or of the Notes) payment of principal and premium, if any, or interest need not be made on such date, but may be made on the next succeeding Business Day with the same
force and effect as if made on the Interest Payment Date, Redemption Date or at the Stated Maturity, as the case may be; provided that no interest shall accrue for the period from and after such Interest Payment Date, Redemption Date or
Stated Maturity, as the case may be. 
 In the event of redemption of this Note in part only, a new Note or Notes of this series
and of like tenor for the unredeemed portion hereof shall be issued in the name of the Holder hereof upon the cancellation hereof. 
 If an Event of Default with respect to Notes shall occur and be continuing, the principal of all of the Notes may be declared due and payable in the manner and with the effect provided in the Indenture.

 All payments of principal, premium, if any, and interest in respect of the Notes shall be made after withholding or deduction
for any present or future taxes, duties, assessments or governmental charges of whatever nature imposed, levied, collected, withheld or assessed by or on behalf of Mexico or any authority therein or thereof having power to tax (“Mexican
Taxes”). In the event of any withholding or deduction for any Mexican Taxes, the Company shall pay such additional amounts (“Additional Amounts”) as will result in receipt by the Holders of Notes on the respective due dates of such
amounts as would have been received by them had no such withholding or deduction (including for any Mexican 

  
 4 

 
Taxes payable in respect of Additional Amounts) been required, except that no such Additional Amounts shall be payable with respect to any payment on a Note to the extent: 

(i) that any such taxes, duties, assessments or other governmental charges are imposed solely because of (A) a
connection between the Holder and Mexico other than the ownership or holding of such Note and the mere receipt of payments with respect to such Note or (B) failure by the Holder or any other Person to comply with any certification,
identification or other reporting requirement concerning the nationality, residence, identity or connection with Mexico of the Holder or any beneficial owner of such Note if compliance is required by law, regulation or by an applicable income tax
treaty to which Mexico is a party, as a precondition to exemption from, or reduction in the rate of, the tax, assessment or other governmental charge and we have given the Holders at least 30 days’ notice prior to the first payment date with
respect to which such certification, identification or reporting requirement is required to the effect that Holders will be required to provide such information and identification; 

(ii) of any such taxes, duties, assessments or other governmental charges with respect to such Note presented for payment
more than 15 days after the date on which such payment became due and payable or the date on which payment thereof is duly provided for and notice thereof given to Holders, whichever occurs later, except to the extent that the Holder of such Note
would have been entitled to such Additional Amounts on presenting such Note for payment on any date during such 15-day period; 
 (iii) of estate, inheritance, gift or other similar taxes, assessments or other governmental charge imposed with respect to such Note; 

(iv) of any tax, duty, assessment or other governmental charge payable otherwise than by deduction or withholding from
payments on such Note; 
 (v) of any payment on such Note to a Holder who is a fiduciary or partnership or a
person other than the sole beneficial owner of any such payment, to the extent that a beneficiary or settlor with respect to such fiduciary, a member of such a partnership or the beneficial owner of such payment would not have been entitled to the
Additional Amounts had such beneficiary, settlor, member or beneficial owner been the Holder of such Note; 

(vi) of any tax, duty, assessment or other governmental charge imposed on a payment to an individual and required to be
made pursuant to European Council Directive 2003/48/EC on the taxation of savings income or any other directive implementing the conclusions of the ECOFIN Council meetings of November 26 and 27, 2000, December 13, 2001, and
January 21, 2003, or any law or agreement implementing or complying with, or introduced in order to conform to, such a directive; and 
 (vii) any combination of the items in Clauses (i) through (vi) above. 

For purposes of the provisions described in Clause (i) above, the term “Holder” of any Note means the direct nominee of
any beneficial owner of such Note, which holds such beneficial owner’s interest in such Note. Notwithstanding the foregoing, the limitations on the Company’s obligation to pay Additional Amounts set forth in Clause (i)(B) above shall not
apply if (a) the provision of information, documentation or other evidence described in such Clause (i)(B) would be materially more onerous, in form, in procedure or in the substance of information disclosed, to a Holder or beneficial owner of
a Note (taking into account any relevant differences between U.S. and Mexican law, regulation or administrative practice) than comparable information or other reporting requirements imposed under

  
 5 

 
U.S. tax law (including the United States—Mexico Income Tax Treaty), regulations (including proposed regulations) and administrative practice or (b) Rule I.3.17.11 (or any successor
provision) is in effect, unless the provision of the information, documentation or other evidence described in such Clause (i)(B) is expressly required by statute, regulation, rule or administrative practice in order to apply Rule I.3.17.11 (or any
successor provision) and the Company cannot obtain such information, documentation or other evidence on its own through reasonable diligence and the Company otherwise would meet the requirements for application of Rule I.3.17.11 (or any successor
provision). In addition, such Clause (i)(B) shall not be construed to require that a non-Mexican pension or retirement fund or a non-Mexican financial institution or any other Person register with the Ministry of Finance and Public Credit for the
purpose of establishing eligibility for an exemption from or reduction of Mexican withholding tax. 
 The Company shall provide
the Trustee with the constancia or other relevant documentation, if any (which may consist of certified copies of such documentation), satisfactory to the Trustee evidencing the payment of Mexican Taxes in respect of which the Company has
paid any Additional Amounts. Copies of such documentation shall be made available to the Holders of the Notes or any Paying Agent, as applicable, upon request therefor. 
 The Company shall pay all stamp, issue, registration, documentary or other similar duties, if any, which may be imposed by Mexico or any governmental entity or political subdivision therein or thereof, or
any taxing authority of or in any of the foregoing, with respect to the Indenture or the issuance of the Notes. 
 All
references herein and in the Indenture to principal, premium, if any, interest or any other amount payable in respect of any Note shall be deemed to include all Additional Amounts, if any, payable in respect of such principal, premium, interest or
other amount payable, unless the context otherwise requires, and express mention of the payment of Additional Amounts in any provision hereof shall not be construed as excluding reference to Additional Amounts in those provisions hereof where such
express mention is not made. 
 In the event that Additional Amounts actually paid with respect to the Notes pursuant to the
preceding paragraphs are based on rates of deduction or withholding of withholding taxes in excess of the appropriate rate applicable to the Holder of such Notes, and, as a result thereof such Holder is entitled to make claim for a refund or credit
of such excess from the authority imposing such withholding tax, then such Holder shall, by accepting such Notes, be deemed to have assigned and transferred all right, title, and interest to any such claim for a refund or credit of such excess to
the Company. However, by making such assignment, the Holder makes no representation or warranty that the Company will be entitled to receive such claim for a refund or credit and incurs no other obligation with respect thereto. 

All references herein and in the Indenture to principal in respect of any Note shall be deemed to mean and include any Redemption Price
payable in respect of such Note pursuant to any redemption right hereunder (and all such references to the Stated Maturity of the principal in respect of any Note shall be deemed to mean and include the Redemption Date with respect to any such
Redemption Price), and all such references to principal, premium, interest or Additional Amounts shall be deemed to mean and include any amount payable in respect hereof pursuant to Section 1009 of the Base Indenture. 

The Company may, at its option, redeem the Notes upon not less than 30 nor more than 60 days’ notice, at any time and, only in the
case of clause (ii) below, from time to time: 
 (i) in whole but not in part, at a Redemption Price equal
to the sum of (A) 100% of the principal amount of the Notes being redeemed, (B) accrued and unpaid interest thereon to the Redemption Date and (C) any Additional Amounts which would otherwise be payable thereon up

  
 6 

 
to but not including the Redemption Date, solely if, as a result of any amendment to, or change in, the laws (or any rules or regulations thereunder) of Mexico or any political subdivision or
taxing authority thereof or therein affecting taxation or any amendment to or change in an official interpretation or application of such laws, rules or regulations, which amendment to or change in such laws, rules or regulations becomes effective
on or after October 27, 2011, the Company would be obligated, after making reasonable endeavors to avoid such requirement, to pay Additional Amounts in excess of the Additional Amounts that the Company would be obligated to pay if payments made
on the Notes were subject to withholding or deduction of Mexican Taxes at the rate of 4.9%; provided, however, that (1) no notice of redemption pursuant to this clause (i) may be given earlier than 90 days prior to the earliest date
on which the Company would be obligated to pay such Additional Amounts if a payment on the Notes were then due and (2) at the time such notice of redemption is given, the Company’s obligation to pay such Additional Amounts remains in
effect; and 
 (ii) in whole or in part, at a Redemption Price equal to the greater of (1) 100% of the
outstanding principal amount of the Notes being redeemed and (2) the sum of the present values of the remaining scheduled payments of principal and interest thereon (exclusive of interest accrued to the Redemption Date) discounted to the
Redemption Date on an annual basis (calculated using a 365-day year or a 366-day year, as applicable, and the actual number of days elapsed) at the Bund Rate plus 50 basis points, plus, in the case of (1) and (2), accrued and unpaid interest on
the principal amount of such Notes to but not including the Redemption Date. 
 For purposes of clause
(ii) above, the following terms shall have the specified meanings: 
 “Bund Rate” means, as of any
Redemption Date, the rate per annum equal to the yield to maturity as of such Redemption Date of the Comparable German Bund Issue, assuming a price for the Comparable German Bund Issue (expressed as a percentage of its principal amount) equal to the
Comparable German Bund Price for such Redemption Date. 
 “Comparable German Bund Issue” means the
German Bundesanleihe security selected by any Reference German Bund Dealer as having a fixed maturity most nearly equal to the remaining term of the Notes to be redeemed and that would be utilized at the time of selection and in accordance with
customary financial practice, in pricing new issues of euro-denominated corporate debt securities in a principal amount approximately equal to the then outstanding principal amount of the Notes to be redeemed and of a maturity most nearly equal to
the remaining term of the Notes to be redeemed; provided, however, that, if the remaining term of the Notes to be redeemed is not equal to the fixed maturity of the German Bundesanleihe security selected by such Reference German Bund Dealer,
the Bund Rate shall be determined by linear interpolation (calculated to the nearest one-twelfth of a year) from the yields of German Bundesanleihe securities for which such yields are given, except that if the remaining term of the Notes to be
redeemed is less than one year, a fixed maturity of one year shall be used. 
 “Comparable German Bund
Price” means, with respect to any Redemption Date, the average of all Reference German Bund Dealer Quotations for such date (which, in any event, must include at least two such quotations), after excluding the highest and lowest such Reference
German Bund Dealer Quotations, or if the Trustee obtains fewer than four such Reference German Bund Dealer Quotations, the average of all such quotations. 
 “Reference German Bund Dealer” means each of Credit Suisse Securities (Europe) Limited and Deutsche Bank AG, London Branch, or their affiliates, which are dealers of German Bundesanleihe
securities and one other leading dealer of German Bundesanleihe securities 

  
 7 

 
reasonably designated by the Company; provided, however, that if any of the foregoing shall cease to be a dealer of German Bundesanleihe securities, the Company will substitute therefor
another dealer of German Bundesanleihe securities. 
 “Reference German Bund Dealer Quotation” means, with respect to
each Reference German Bund Dealer and any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable German Bund Issue (expressed in each case as a percentage of its principal amount) quoted in writing
to the Trustee by such Reference German Bund Dealer at 3:30 p.m. (Frankfurt, Germany time) on the third business day preceding such Redemption Date. 
 The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company, on the one hand, and the rights of the Holders
of the Notes, on the other hand, at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Notes at the time Outstanding. The Indenture also contains provisions (1) permitting the
Holders of a majority in principal amount of the Notes at the time Outstanding, on behalf of the Holders of all Notes, to waive compliance by the Company with certain provisions of the Indenture and (2) permitting the Holders of a majority in
principal amount of the Notes at the time Outstanding, on behalf of the Holders of all Notes, to waive certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and
binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note.

 As provided in and subject to the provisions of the Indenture, the Holder of this Note shall not have the right to institute
any proceeding with respect to the Indenture or for the appointment of a receiver or trustee, or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect
to the Notes, the Holders of not less than 25% in principal amount of the Notes at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee
indemnity reasonably satisfactory to it, and the Trustee shall not have received from the Holders of a majority in principal amount of Notes at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any
such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Note for the enforcement of any payment of principal hereof or premium, if any,
and/or interest hereon on or after the respective due dates expressed herein. 
 No reference herein to the Indenture and no
provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and premium, if any, and interest on this Note at the times, place and rate, and in the coin
or currency, herein prescribed. 
 As provided in the Indenture, and subject to certain limitations therein set forth
(including, without limitation, the restrictions on transfer under Section 304 of the Indenture), the transfer of this Note is registrable in the Security Register, upon surrender of this Note for registration of transfer at the office of the
Trustee or agency of the Company in any place where the principal of and any premium and interest on this Note are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security
Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Notes of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, shall be issued
to the designated transferee or transferees. 

  
 8 

 The Notes are issuable only in registered form without coupons in denominations of
€100,000 and integral multiples of €1,000 in excess thereof. As provided in the Indenture, and subject to certain limitations therein set forth, Notes are exchangeable for a like aggregate principal amount of Notes of like tenor of a
different authorized denomination, as requested by the Holder surrendering the same. 
 No service charge shall be made for any
such registration of transfer or exchange, but the Company or the Trustee may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. 

Prior to due presentment of this Note for registration of transfer, the Company, the Trustee and any agent of the Company or of the
Trustee may treat the Person in whose name this Note is registered as the owner hereof for all purposes, whether or not this Note is overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

 This Note is a Global Note and is subject to the provisions of the Indenture relating to Global Notes, including the
limitations in Section 304 of the Indenture on transfers and exchanges of Global Notes. 
 This Note and the Indenture
shall be governed by, and construed in accordance with, the law of the State of New York. 
 All terms used in this Note which
are defined in the Indenture shall have the meanings assigned to them in the Indenture.
