      TURKCELL ANNOUNCES REVISION TO INTERCONNECTION AGREEMENT WITH TELSIM

Istanbul, Turkey, October 13, 2003 - Turkcell (NYSE:TKC, ISE:TCELL), the leading
provider of mobile communications services in Turkey, today announced that it
has signed an agreement with Telsim amending certain sections of the
Interconnection Agreement dated October 4, 1999, between Turkcell and Telsim
("the Agreement"). Turkcell and Telsim amended pricing terms of the Agreement in
response to the Access and Interconnection Regulation introduced by the
Telecommunication Authority of Turkey in May 2003. The amended agreement came
into effect as of today.

All the following rates are set in Turkish Lira and will be revised by the
parties every three months based on the consumer price index. During periods of
sharp devaluation of the Turkish Lira, the devaluation rate will also be taken
into consideration in such revisions. The amended pricing terms of the Agreement
will be applicable until the end of 2004 when both parties will revise them
based on conditions reached at that time. All the rates are net of all
applicable taxes. US Dollar rates given in brackets after Turkish Lira
denominated rates below are calculated based on the current exchange rate and
may be subject to change.

According to the revised agreement, Turkcell will pay TRL210,000 (apprx.
US$0.152) per minute to Telsim for traffic originating on Turkcell's network and
terminating on Telsim's network. Telsim will pay the same rate to Turkcell for
the reverse traffic. This rate, after quarterly revisions, will be subject to a
discount of 4.762% in May 2004 as part of this agreement. Turkcell will pay
Telsim TRL25,000 (apprx. US$0.018), for each SMS originating on Turkcell's
network and terminating on Telsim's network. Telsim will pay the same rate to
Turkcell for the reverse traffic.

                                                           FOR IMMEDIATE RELEASE



       TURKCELL ANNOUNCES THE DISPUTE ON FREQUENCY USAGE FEES IS RESOLVED



Istanbul, Turkey, October 15, 2003 - Turkcell (NYSE:TKC, ISE:TCELL), the leading
provider of mobile communications services in Turkey, today announced that the
dispute with the Telecommunications Authority (the "Authority") on frequency
usage fee is resolved.

In January 2002, Turkcell applied to the Authority requesting it to review the
protocol obligating Turkcell to collect frequency usage fees from its
subscribers on the grounds that it was impossible to collect these fees from
prepaid subscribers. Upon the request of the Authority in February 2002 to pay
the frequency usage fees, Turkcell filed a lawsuit against the Authority
requesting cancellation of the protocols obligating it to collect the frequency
usage fees from prepaid subscribers. In July 2002, the court decided in favor of
Turkcell. However, the Authority appealed the decision and in March 2003 the
Court of Appeals accepted the Authority's appeal and annulled the decision of
the lower court.

After the Court of Appeals' decision, Turkcell paid TL86.9 trillion (US$61.1
million, as of June 30, 2003) for the year 2003. Turkcell did not paid the fees
due for 2002, as the legal process was ongoing, however, Turkcell accrued legal
reserves in its financials. The disputed amount for the year 2002 is TL52.3
trillion (US$36.8 million, as of June 30, 2003) in principal and TL58.6 trillion
(US$41.2 million as of June 30,2003) in interest as of June 30, 2003.

The lower court revised its decision to make it in line with the Court of
Appeal's decision and rejected Turkcell's request the cancellation of the
protocols obligating it to collect the frequency usage fees from the prepaid
subscribers. The decision is final and not subject to appeal.
