        Notes to Condensed Consolidated Financial Statements (unaudited)


NOTE A - BASIS OF PRESENTATION

The accompanying unaudited condensed consolidated financial statements have been
prepared in accordance with generally accepted accounting principles for interim
financial information and with the instructions to Form 10-Q and Rule 10-01 of
Regulation S-X. Accordingly, they do not include all of the information and
footnotes required by generally accepted accounting principles for complete
financial statements. In the opinion of management, all adjustments (consisting
of normal recurring accruals) considered necessary for a fair presentation have
been included. Operating results for the three and six months ended June 30,
1999 are not necessarily indicative of the results that may be expected for the
year ending December 31, 1999. For further information, refer to the
consolidated financial statements and footnotes thereto included in the
Company's annual report on Form 10-K for the year ended December 31, 1998.

In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities," which is required to be adopted in fiscal years
beginning after June 15, 2000. Management does not anticipate that the adoption
of this new standard will have a significant effect on earnings or the financial
position of the Company.

NOTE B - MERGER AGREEMENT

On May 3, 1999, the Company announced that it had entered into an agreement with
SBC Communications Inc. ("SBC") under which it would be acquired in a
transaction valued at $29.50 per outstanding share. In addition, based on
information provided by SBC, Telefonos de Mexico S.A. de C.V. will purchase an
interest in the SBC subsidiary that will acquire the Company. The Company
expects to complete the merger in the third quarter of 1999 pending regulatory
approvals.

NOTE H - DEFERRED STOCK OPTION EXPENSE

In connection with the distribution of all the common stock of CoreComm Limited
to the Company's shareholders in 1998, the Company made an equitable adjustment
to certain employee and non-employee director stock options. The deferred stock
option expense included in shareholders' deficiency was a non-cash charge
recorded in accordance with APB Opinion No. 25, "Accounting for Stock Issued to
Employees" as a result of the new measurement date. The Company recognized
$5,241,000 as a non-cash stock option charge in the six months ended June 30,
1999. The remaining $11,046,000 will be charged to stock option expense over the
vesting period of the stock options as follows: $5,240,000 in 1999, $4,550,000
in 2000 and $1,256,000 in 2001.

NOTE I - COMMITMENTS AND CONTINGENT LIABILITIES

As of June 30, 1999, the Company was committed to purchase approximately
$7,800,000 for cellular network and other equipment and for construction
services. In addition, as of June 30, 1999, the Company had commitments to
purchase cellular telephones, pagers and accessories of approximately
$2,000,000.

In 1992, the Company entered into an agreement which in effect provides for a
twenty year license to use its service mark in Puerto Rico and U.S. Virgin
Islands which is also licensed to many of the non-wireline cellular systems in
the United States. The Company is required to pay licensing and advertising
fees, and to maintain certain service quality standards. The total fees paid for
1999 were $302,000, which were determined by the size of the Company's markets.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND
         FINANCIAL CONDITION

On May 3, 1999, the Company announced that it had entered into an agreement with
SBC Communications Inc. ("SBC") under which it would be acquired in a
transaction valued at $29.50 per outstanding share. In addition, based on
information provided by SBC, Telefonos de Mexico S.A. de C.V. will purchase an
interest in the SBC subsidiary that will acquire the Company. The Company
expects to complete the merger in the third quarter of 1999 pending regulatory
approvals.

In 1998, the Company acquired, through its wholly-owned subsidiary CoreComm
Limited, three communications related businesses in the United States and was
the high bidder for 15 LMDS licenses in Ohio. As a result of acquisitions in
April and June 1998, the Company consolidated the results of operations of the
acquired businesses from the dates of acquisition. In September 1998, the
Company completed the distribution of all of the common stock of CoreComm
Limited to its shareholders.

                              RESULTS OF OPERATIONS

THREE MONTHS ENDED JUNE 30, 1999 AND 1998

Service revenue increased to $42,487,000 from $38,308,000. Service revenue
includes $1,200,000 in 1998 from acquired businesses. For the Company's cellular
and paging business in Puerto Rico and the U.S. Virgin Islands, lower average
revenue and minutes of use of new prepaid subscribers and the selection by
existing subscribers of alternate rate plans resulted in average monthly revenue
per cellular subscriber for the second quarter decreasing to $41 in 1999 from
$55 in 1998. The Company expects these trends to continue for the foreseeable
future. Ending subscribers were 361,900 and 234,400 as of June 30, 1999 and
1998, respectively. Ending pagers in use were 59,900 and 53,400 as of June 30,
1999 and 1998, respectively.

The income from equipment, before depreciation of rental equipment, decreased to
$304,000 from $665,000 due to lower selling prices on digital cellular
telephones sold to prepaid subscribers. The Company intends to continue to sell
telephones at or above cost to prepaid subscribers. The income from equipment in
1998 includes $45,000 from acquired businesses.

Operating expenses decreased to $4,190,000 from $5,303,000. Operating expenses
in 1998 include $1,052,000 from acquired businesses. For the Company's cellular
and paging business in Puerto Rico and the U.S. Virgin Islands, operating
expenses decreased to $4,190,000 from $4,251,000 primarily due to a reduction in
interconnection expense, offset by additional costs associated with the expanded
network (including paging operations). Operating expenses as a percentage of
service revenue, excluding CoreComm Limited businesses, decreased to 10% in 1999
from 11% in 1998.

          Cellular Communications of Puerto Rico, Inc. and Subsidiaries


Selling, general and administrative expenses decreased to $17,649,000 from
$19,058,000. Selling, general and administrative expenses include $1,417,000
from acquired businesses and general and administrative expenses of the parent
company of $510,000 in 1999 and $832,000 in 1998. For the Company's cellular and
paging business in Puerto Rico and the U.S. Virgin Islands, selling, general and
administrative expenses increased to $17,139,000 from $16,809,000 primarily as a
result of an increase in selling and marketing costs, which was partially offset
by a decrease in bad debt expense.

Stock option expense of $2,621,000 in 1999 is a non-cash charge recorded in
accordance with APB Opinion No. 25, "Accounting for Stock Issued to Employees"
due to an equitable adjustment made to certain employee and non-employee
director stock options in connection with the distribution of CoreComm Limited
to the Company's shareholders in 1998. The Company has $11,046,000 of deferred
stock option expense as of June 30, 1999 that will be charged as non-cash stock
option expense over the vesting period of the stock options as follows:
$5,240,000 in 1999, $4,550,000 in 2000 and $1,256,000 in 2001.

Depreciation of rental equipment increased to $380,000 from $275,000 due to an
increase in the number of rental telephones and pagers.

Depreciation expense increased to $7,236,000 from $6,423,000 primarily because
of an increase in property, plant and equipment.

Amortization expense decreased to $1,696,000 from $1,710,000 primarily due to a
decrease in goodwill from the 1998 acquisitions.

Interest income and other, net, increased to $741,000 from $494,000 primarily
due to gains on disposals of property, plant and equipment of $327,000.

Interest expense increased to $7,931,000 from $5,395,000 as a result of the new
bank loan commencing in August 1998.

The provision for income taxes increased to $618,000 from $370,000 as a result
of an increase in Puerto Rico and U.S. Virgin Islands taxable income of certain
of the Company's consolidated subsidiaries.

SIX MONTHS ENDED JUNE 30, 1999 AND 1998

Service revenue increased to $83,336,000 from $72,767,000. Service revenue
includes $1,200,000 in 1998 from acquired businesses. For the Company's cellular
and paging business in Puerto Rico and the U.S. Virgin Islands, lower average
revenue and minutes of use of new prepaid subscribers and the selection by
existing subscribers of alternate rate plans resulted in average monthly revenue
per cellular subscriber for the six months ended June 30 decreasing to $42 in
1999 from $55 in 1998. The Company expects these trends to continue for the
foreseeable future. Ending subscribers were 361,900 and 234,400 as of June 30,
1999 and 1998, respectively. Ending pagers in use were 59,900 and 53,400 as of
June 30, 1999 and 1998, respectively.

telephones sold to prepaid subscribers. The Company intends to continue to sell
telephones at or above cost to prepaid subscribers. The income from equipment in
1998 includes $45,000 from acquired businesses.

Operating expenses decreased to $8,071,000 from $9,418,000. Operating expenses
in 1998 include $1,052,000 from acquired businesses. For the Company's cellular
and paging business in Puerto Rico and the U.S. Virgin Islands, operating
expenses decreased to $8,071,000 from $8,366,000 primarily due to a reduction in
interconnection expense, offset by additional costs associated with the expanded
network (including paging operations). Operating expenses as a percentage of
service revenue, excluding CoreComm Limited businesses, decreased to 10% in 1999
from 12% in 1998.

Selling, general and administrative expenses decreased to $34,614,000 from
$35,687,000. Selling, general and administrative expenses in 1998 include
$1,417,000 from acquired businesses and general and administrative expenses of
the parent company of $977,000 in 1999 and $1,328,000 in 1998. For the Company's
cellular and paging business in Puerto Rico and the U.S. Virgin Islands,
selling, general and administrative expenses increased to $33,637,000 from
$32,942,000 primarily as a result of an increase in selling and marketing costs,
which was partially offset by a decrease in bad debt expense.

Stock option expense of $5,241,000 in 1999 is a non-cash charge recorded
in accordance with APB Opinion No. 25, "Accounting for Stock Issued to
Employees" due to an equitable adjustment made to certain employee and
non-employee director stock options in connection with the distribution of
CoreComm Limited to the Company's shareholders in 1998. The Company has

The provision for income taxes increased to $1,460,000 from $836,000 as a result
of an increase in Puerto Rico and U.S. Virgin Islands taxable income of certain
of the Company's consolidated subsidiaries.


                         LIQUIDITY AND CAPITAL RESOURCES


The Company requires capital to expand its Puerto Rico and U.S. Virgin Islands
cellular and paging network and for debt service. The Company is currently
adding cell sites and increasing capacity throughout its Puerto Rico and U.S.
Virgin Islands markets. The Company expects to use approximately $17,800,000 in
the second half of 1999 for contemplated additions to the cellular network, the
paging network and for other non-cell site related capital expenditures. The
Company's commitments at June 30, 1999 of $7,800,000 for cellular network and
other equipment and for construction services are included in the total
anticipated expenditures. The Company expects to be able to meet these
requirements with cash and securities on hand and cash from operations.

In August 1998, a wholly-owned indirect subsidiary of the Company, CCPR
Services, Inc. ("Services"), entered into a $170,000,000 credit agreement with
various banks. Services has $15,000,000 available under the bank loan until
September 2001. The terms include the payment of interest at least quarterly at
a floating rate, which is, at Services' option, either (a) the greater of the
bank's prime rate or the Federal Funds Rate plus 0.5% or (b) LIBOR, plus, based
on the ratio of CCPR, Inc. (a wholly-owned subsidiary of the Company and the
parent company of Services) and subsidiaries' debt to cash flow and the floating
rate in effect, either 0% to 1.25% or 1.25% to 2.5%. The effective rate on
Services' borrowings as of June 30, 1999 was 6.8%. The terms also include an
unused commitment fee of 0.5% per annum which is payable quarterly. Principal
payments commence on September 30, 2001 based on two amortization schedules. One
schedule is for the first $95,000,000 borrowed which includes quarterly payments
until June 2006. The other schedule is for the remainder of the amount borrowed
which includes quarterly payments until June 2005.

In connection with the bank loan, CCPR, Inc. has pledged to the banks the stock
of its subsidiaries and CCPR, Inc. and its subsidiaries have given the banks a
security interest in their assets. CCPR, Inc. and its other subsidiaries have
guaranteed the payment in full when due of the principal, interest and fees
owing under the bank loan, which guarantee is full, joint and several. The bank
loan also includes, among other things, restrictions on CCPR, Inc. and its
subsidiaries (i) dividend payments, (ii) acquisitions, (iii) investments, (iv)
sales and dispositions of assets, (v) additional indebtedness and (vi) liens.
The bank loan requires that CCPR, Inc. and subsidiaries maintain certain ratios
of indebtedness to cash flow, fixed charges to cash flow and debt service to
cash flow.

<PAGE>   14
          Cellular Communications of Puerto Rico, Inc. and Subsidiaries


In January 1997, Services issued $200,000,000 principal amount 10% Senior
Subordinated Notes due 2007 (the "Notes"). The Notes are unconditionally
guaranteed by CCPR, Inc., which guarantee is full, joint and several. The Notes
are due on February 1, 2007. Interest on the Notes is payable semiannually on
February 1 and August 1. The Notes are redeemable, in whole or in part, at the
option of Services at any time on or after February 1, 2002, at a redemption
price of 105% that declines annually to 100% in 2005, in each case together with
accrued and unpaid interest to the redemption date. The Indenture contains
certain covenants with respect to Services, CCPR, Inc. and certain subsidiaries
that limit their ability to, among other things, (i) incur additional
indebtedness, (ii) pay dividends or make other distributions or restricted
payments, (iii) create liens, (iv) sell assets, (v) enter into mergers or
consolidations or (vi) sell or issue stock of subsidiaries.

The Company is highly leveraged. Such leverage could limit the Company's ability
to obtain additional financing for working capital, capital expenditures,
acquisitions or general corporate purposes, increases its vulnerability to
adverse changes in general economic conditions or increases in interest rates,
and requires that a substantial portion of cash flow operations be dedicated to
debt service requirements. The leveraged nature of the Company and the Company's
continued compliance with the restrictions in its debt agreements could limit
its ability to respond to market conditions, meet extraordinary capital needs or
restrict other business activities such as acquisitions. In addition, the
Company is a holding company with no significant assets other than its
investments in and advances to its subsidiaries. The Company is therefore
dependent upon receipt of funds from its subsidiaries to meet its own
obligations, however the debt agreements effectively prevent the payment of
dividends, loans or other distributions to the Company. The Company expects to
be able to meet its own obligations at least through the next twelve months with
cash, cash equivalents and marketable securities on hand.

Management does not anticipate that the Company and its subsidiaries will
generate sufficient cash flow from operations to repay at maturity the entire
principal amount of the outstanding indebtedness. Accordingly, the Company may
be required to consider a number of measures, including (i) refinancing all or a
portion of such indebtedness, (ii) seeking modifications of the terms of such
indebtedness, (iii) seeking additional debt financing, which would be subject to
obtaining necessary lender consents, (iv) seeking additional equity financing or
(v) a combination of foregoing. The particular measures the Company may
undertake and the ability of the Company to accomplish those measures will
depend on the financial condition of the Company and its subsidiaries at the
time, as well as a number of factors beyond the control of the Company. No
assurance can be given that any of the foregoing measures can be accomplished,
or can be accomplished on terms which are favorable to the Company.

Cash provided by operating activities was $20,094,000 and $20,219,000 for the
six months ended June 30, 1999 and 1998, respectively. The increase is primarily
a result of an increase in operating income and changes in operating assets and
liabilities. Purchases of property, plant and equipment of $21,078,000 in 1999
were primarily for additional cell sites and increased capacity in the Company's
cellular and paging networks.

<PAGE>   15
          Cellular Communications of Puerto Rico, Inc. and Subsidiaries


Write-offs of accounts receivable, net of recoveries as a percentage of service
revenues was 1.79% for the six months ended June 30, 1999 compared to 3.6% for
the year ended December 31, 1998. This percentage decreased because the Company
and its subsidiaries have increased prepaid subscribers.


YEAR 2000

The Company had a comprehensive Year 2000 project designed to identify and
assess the risks associated with its information systems, products, operations
and infrastructure, suppliers, and customers that are not Year 2000 compliant,
and to develop, implement and test remediation and contingency plans to mitigate
these risks. The project included four phases: (1) identification of risks, (2)
assessment of risks, (3) development of remediation and contingency plans and
(4) implementation and testing. The Company's assessment was focused on its
information technology ("IT") systems, in particular it's cellular and paging
network and its billing, provisioning and customer service system. The Company
also evaluated the readiness of third-parties such as utility companies that the
Company depends upon for the operation of its network. The Company's leased
office space and other non-IT equipment which may have embedded technology that
may be affected by the Year 2000 problem is being separately assessed.

The Company completed the assessment, remediation, and testing of its critical
IT systems. In addition, the evaluation of the readiness of major third-parties
is complete. The Company completed contingency plans for all critical business
processes. Throughout the remainder of the year the Company will review and
update its plans to ensure their applicability. In addition, the Company will
ensure that all personnel involved in the contingency plans are properly trained
and prepared. The Company incurred approximately $2,300,000 related to its Year
2000 project and estimates that it will incur nominal additional costs.

The Company currently believes that the most reasonably likely worst case
scenario with respect to the Year 2000 is the failure of the electric company or
the local exchange telephone company to be ready for the year 2000. This could
cause a temporary interruption in the provision of service to customers or in
the Company's ability to complete telephone calls, or both. Either or both could
have a material adverse effect on operations, although it is not possible at
this time to quantify the amount of revenues and gross profit that might be
lost, or the costs that could be incurred. The contingency plan to address some
of these risks involve utilizing back-up power supplies and alternative
interconnections, which would require time to implement and may be constrained
due to capacity and/or training limitations. The Company has had experience in
implementing its disaster recovery plan due to Hurricane Georges, which struck
Puerto Rico and the U.S. Virgin Islands in September 1998 and caused the
electric company and local exchange telephone company to experience service
interruptions.

          Cellular Communications of Puerto Rico, Inc. and Subsidiaries


Because the Company uses a variety of information systems and has additional
systems embedded in its operations and infrastructure, the Company cannot be
sure that all of its systems will work together in a Year 2000-ready fashion.
Furthermore, the Company cannot be sure that it will not suffer business
interruptions, either because of its own Year 2000 problems or those of
third-parties upon whom the Company is reliant for services. The Company is
continuing to evaluate its Year 2000-related risks and corrective actions.
However, the risks associated with the Year 2000 problem are pervasive and
complex; they can be difficult to identify and address, and can result in
material adverse consequences to the Company. Even though the Company completed
all of its assessments, identified and tested remediation plans believed to be
adequate, and developed contingency plans believed to be adequate, some problems
may not be identified or corrected in time to prevent material adverse
consequences to the Company.
