Item 4.  Ownership:

(a)     Amount beneficially owned:

     SBCI is  required  under  Mexican law to hold its shares of the Issuer in a
     trust.  Under the terms of the  trust,  SBCI has an  unrestricted  right to
     transfer its Series AA shares ("AA Shares") or convert its AA Shares into L
     Shares (on a one-for-one  basis)  subject to the provisions of Mexican law.
     The  total  number  of L  Shares  that  SBCI  would  beneficially  own upon
     conversion of the 1,059,890,076 AA Shares that it holds is 1,059,890,076.

(b)     Percent of class:                                                  7.6%

     The above  percentage is based upon:  (1) a total of 14,010  million shares
     outstanding as of December 31, 2000  (according to the financial  statement
     for the fourth quarter 2000 published by the Issuer on its website) and (2)
     the assumption  that the L Shares issuable upon conversion of the AA Shares
     are issued and outstanding at the time of such calculation.

(c)  On March  28,  2001,  SBCI  and  Carso  Global  Telecom,  S.A.  de C.V.
     ("Carso")   entered  into  a  shareholders   agreement  (the   "Agreement")
     concerning  voting and disposition of SBCI's AA Shares.  Under the terms of
     the  Agreement,  each  party  agrees  to vote its AA Shares in favor of the
     other party's candidates for the Issuer's Board of Directors. The Agreement
     provides that SBCI has an  unrestricted  right to transfer its AA Shares or
     to  convert  its AA  Shares  into L Shares  provided  that  after  any such
     transaction,  the remaining number of outstanding AA Shares  constitutes at
     least 20  percent  of the  outstanding  capital  stock of the  Issuer.  The
     Agreement also provides that in the event Carso sells  sufficient AA Shares
     so that it no longer owns a majority of the  outstanding  AA Shares,  Carso
     may require SBCI to sell AA Shares to the same  purchaser on the same terms
     and conditions.

    (i)    Sole power to vote or to direct the vote:                   0 Shares
