Enclosures: Press release dated December 4, 2003 - Turkcell Provides Update On

                                                           FOR IMMEDIATE RELEASE



            TURKCELL PROVIDES UPDATE ON DISPUTE WITH TURK TELEKOM ON
                         INTERCONNECTION FEE STRUCTURE


Istanbul, Turkey: December 4, 2003--Turkcell (NYSE:TKC, ISE: TCELL), the leading
provider of mobile communications services in Turkey, today announced a new
development regarding the interconnection fee dispute between Turk Telekom and
Turkcell.

In November 2000, Turk Telekom demanded that Turkcell share all interconnection
fees equally with Turk Telekom going forward and retroactively from April 1998
as a result of the favorable decision acquired by the Turkish Electrical
Engineer's Society ("EES") in their lawsuit against Turk Telekom filed with the
Ankara Ninth Administrative Court in October 2000. In that lawsuit, the EES
claimed that the interconnection fee regime set out in the Interconnection
Agreement between Turkcell and Turk Telekom violated public policy. Although
Turkcell was not a party to this lawsuit, the Ankara Ninth Administrative Court
annulled the interconnection fee structure set out in the Interconnection
Agreement between Turkcell and Turk Telekom. However, in July 2003, Turkcell
obtained a court decision from the Ankara Seventh Commercial Court, which stated
that Turk Telekom should continue to comply with the original interconnection
agreement until a new contract was reached. Furthermore, following Turk
Telekom's demand for opinions concerning the Ankara Ninth Administrative Court's
decision regarding revenue distribution, both the Ankara Ninth Administrative
Court and the Court of Cassation issued decrees implying that the Ankara Ninth
Administrative Court's prior verdict did not involve equal interconnection fee
sharing and stated that the conflict should be resolved by a mutual agreement by
the parties.

On December 3, 2003, Turk Telekom informed Turkcell that it has stopped making
its monthly interconnection fee payments in accordance with the recently
obtained injunction from the Ankara First Commercial Court. Previously, the
Ankara First Commercial Court twice rejected Turk Telekom's similar claims.
Accordingly, Turk Telekom did not make the interconnection fee payment for
October 2003 that is scheduled for November 30, 2003, amounting to TL35.9
trillion (approximately US$24.7mn as of today). The lawsuit overseen in the
Ankara First Commercial Court involves the interconnection fee payments
applicable for the period of September 2001 to August 2002, amounting to TL490
trillion (approximately US$355.9 mn as of September 30, 2003).

                                       1




Considering the new interconnection agreement between Turk Telekom and Turkcell,
which does not entail equal sharing of interconnection fees, the court decision
of the Ankara Seventh Commercial Court and opinions of the Court of Cassation
and the Ankara Ninth Administrative Court, Turkcell believes that the recent
injunction decision is unfair and inconsistent with the prior court decisions.
Additionally, Turkcell believes that the non-payment conflicts created by Turk
Telekom are not reasonable and against the principles of the new interconnection
agreement signed between the parties.

The case regarding the essence of this dispute continues in the Ankara Seventh
Commercial Court.
