CUSIP No.  4005013100                                               Page 7 of 16

aggregate consideration in the Offers was approximately $7.5 million and was
paid in cash. No additional consideration was paid in connection with the
Offers. The source of the consideration paid in the Offers was an unsecured loan
for $10,007,500 from an affiliate of Movil Access. Subsequent to the
consummation of the Offers, the Company completed a share exchange pursuant to
which all Series A shares and Series V shares (including those underlying the
ADSs) were exchanged, at a ratio of 20 (twenty) to 1 (one), for shares of Common
Stock (the "Exchange"). After the Exchange, the shares acquired in the Offers
represented 69,413,052 shares of Common Stock.

      In a series of open-market purchases on the Mexican Stock Exchange, Movil
acquired 253,500 shares of Common Stock, as described in item (5) below. The
source of the consideration for such open-market purchases was the working
capital of Movil Access.

Salinas has acquired 4,319,270 shares of Common Stock (on a post-Exchange basis)
of the Company, as described in item (5) below. The source of the consideration

Persons beneficially owned, in the aggregate 73,985,822 shares of Common Stock,
of which Mr. Salinas directly owns 4,319,270 shares of Common Stock. Item 4.
Purpose of Transaction.

      On June 12, 2003, Biper and Movil (collectively, the "Purchasers") entered
into an Acquisition Agreement, dated as of June 12, 2003 (the "Acquisition
Agreement"), by and among Bell Atlantic International, Inc., a Delaware
corporation ("BAII"), Bell Atlantic Latin America Holdings, Inc., a Delaware
corporation ("BALAH"), Bell Atlantic New Zealand Holdings, Inc., a Delaware
corporation ("BANZHI"; and BAII, BALAH and BANZHI, collectively, the "Verizon
Selling Shareholders") and Vodafone Americas B.V., a limited liability company
organized and existing under the laws of The Netherlands ("Vodafone Americas"),
pursuant to which the Purchasers agreed to offer to purchase for cash all of the
issued and outstanding shares of capital stock of the Company pursuant to the
concurrent Offers at a price equal to 0.05712180 Mexican pesos per Series A
Share (or the U.S. dollar equivalent), 0.05712180 Mexican pesos per Series V
Share (or the U.S. dollar equivalent) and the U.S. dollar equivalent of 5.712180
Mexican pesos per ADS. Pursuant to the Acquisition Agreement, Vodafone Americas
and the




CUSIP No.  4005013100                                               Page 8 of 16

Verizon Selling Shareholders agreed to tender all of their respective holdings
of capital stock of the Company in the Offers. As of the date of the Acquisition
Agreement, the Verizon Selling Shareholders reported that they owned, in the
aggregate, 657,966,431 Series A shares of the Company, 74,752,002 Series V
Shares and 14,000 ADSs (the "Verizon ADSs") representing approximately 39.4% of
the total capital stock of the Company (collectively, the "Verizon Shares"). As
of such date, Vodafone Americas reported that it owned 303,326,053 Series A
Shares and 339,617,555 Series V Shares representing approximately 34.5% of the
total capital stock of the Company (collectively, the "Vodafone Shares").

      In connection with the transactions contemplated by the Acquisition
Agreement, Vodafone Americas and the Verizon Selling Shareholders also entered
into an Escrow Agreement, dated as of June 12, 2003 (the "Escrow Agreement"), by
and among Purchasers, BAII, BALAH, BANZHI, Vodafone Americas and The Bank of New
York, a New York banking corporation (the "Escrow Agent"), pursuant to which
Vodafone Americas and the Verizon Selling Shareholders agreed to deposit the
Vodafone Shares and the Verizon Shares (other than the Verizon ADSs) in a
securities account for the benefit of the Escrow Agent. Each of Vodafone
Americas and the Verizon Selling Shareholders irrevocably appointed the Escrow
Agent as its attorney-in-fact and proxy to tender such securities into the
Mexican Offer. As promptly as practicable, but in no event more than two
business days after the commencement of the Offers, the Escrow Agent was
obligated to tender the Vodafone Shares and the Verizon Shares (other than the
Verizon ADSs) into the Mexican Offer.

      Pursuant to the Escrow Agreement, the Purchasers also agreed to deposit
into escrow with the Escrow Agent an amount equal to $10 million, representing
the U.S. dollar equivalent of the aggregate consideration to be offered to the
holders of all of the issued and outstanding capital stock of the Company,
including the Series V Shares and ADSs held by the public shareholders. Promptly
following acceptance for purchase of all of the securities tendered in the
Offers, the Escrow Agent, upon instructions from the Purchasers, was obligated
to deliver the amounts necessary to pay for the tendered securities to the
depositaries for the Mexican Offer and the U.S. Offer.

      In accordance with the Acquisition Agreement, each of Vodafone Americas
and Verizon Selling Shareholders tendered all of its holdings of capital stock
of the Company in the Mexican Offer and did not withdraw such shares. On July
28, 2003 the Mexican Offer expired and on July 29, 2003 the U.S. Offer expired,
and Movil accepted for payment all shares of the Company's capital stock validly
tendered




CUSIP No.  4005013100                                               Page 9 of 16

into the Offers and not withdrawn. Following the consummation of the Offers, the
Reporting Persons beneficially owned all of the shares of capital stock of the
Company previously owned by Vodafone Americas and the Verizon Selling
Shareholders. In addition, Vodafone Americas, the Verizon Selling Shareholders
and the Company terminated the Shareholders Agreement, dated March 30, 2001, by
and among the Company, the Verizon Selling Shareholders and Vodafone Americas
with effect from the consummation of the Offers.

      The foregoing summary of the material provisions of the Acquisition
Agreement and the Escrow Agreement is qualified in its entirety by reference to
the respective agreements, copies of which are filed hereto as Exhibits 1 and 2,
respectively. Exhibits 1 and 2 are specifically incorporated herein by reference
in answer to this Item 4.

      The purpose of the Offers was to enable the Reporting Persons to acquire
control of the Company.

      In addition to the shares of capital stock acquired in the Offers, each of
Movil and Mr. Salinas has engaged in a series of open-market purchases on the
Mexican Stock Exchange, acquiring 253,500 and 4,319,270 shares of Common Stock,
respectively, as described in Item 5 below.

      As set forth in the publicly-filed documents in connection with the
Offers, the Company is highly leveraged and has insufficient cash flow from
operations and cash on hand to meet its debt obligations. At this time, Movil
does not contemplate making any capital contribution to the Company.

      The Reporting Persons are continually evaluating and reviewing their
present and future interests in and intentions with respect to the Company and
the Company's business affairs, financial position and prospects. Based on such
evaluation and review, general economic and industry conditions, and other
factors that the Reporting Persons deem relevant, the Reporting Persons may
consider from time to time various courses of action of the types described in
clauses (a) through (j) of Item 4 of Schedule 13D. Such actions may include,
among other things, the acquisition of Common Stock or ADSs through open market
purchases, privately negotiated transactions, tender offers, exchange offers, a
merger, a reorganization or other business combination transaction, or
otherwise, as applicable, or the Reporting Persons may sell all or a portion of
the Common Stock in privately negotiated transactions or in the open market, in
each case subject to the factors and conditions referred to above. In addition,
the Reporting Persons may formulate other purposes, plans or proposals regarding
the Company or any of its securities to




CUSIP No.  4005013100                                              Page 10 of 16

the extent deemed advisable in light of general investment and trading policies,
market conditions or other factors.

Item 5. Interest in Securities of the Issuer.

      (a) As set forth above, pursuant to the Offers, Movil acquired 414,369,557
Series V shares, 961,292,484 Series A shares and 125,990 ADSs of the Company.
Subsequent to the consummation of the Offers, the Company completed the Exchange
pursuant to which all Series A shares and Series V shares (including those
underlying the ADSs) were exchanged, at a ratio of 20 (twenty) to 1 (one), for
shares of Common Stock of the Company. After the Exchange, the shares acquired
