                    TURKCELL SIGNS GSM PARTNERSHIP IN UKRAINE


Istanbul, Turkey: April 2, 2004 - Turkcell (NYSE: TKC, ISE: TCELL), the leading
provider of mobile communications in Turkey, announced today that it signed the
closing of the final agreement with the current partners of Digital Cellular
Communication (DCC) regarding Turkcell's and DCC's partnership which will
trigger the start of DCC's GSM operations in Ukraine.

The contract was signed by representatives of both parties during the
Turkish-Ukraine Business Council meetings being held in Kiev by DEIK (The
Foreign Economic Relations Board). These signatures mark the start of the
operational phase of the partnership. The signature ceremony was attended by Mr.
Mehmet Emin Karamehmet, the President of Cukurova Holding A.S., Mr. Muzaffer
Akpinar, Turkcell's Chief Executive, and partners of DCC. The Prime Ministers of
Turkey and Ukraine, Recep Tayyip Erdogan and Victor Yanukovich respectively,
were also present at the ceremony.

As part of the agreement, Turkcell will hold a 51% stake in the new company
after buying DCC shares owned by System Capital Management and Valeriy
Grigorievich Stepanenko for US$50 million. Turkcell's investment, together with
its infrastructure and service expertise, is expected to increase DCC's market
share in Ukraine. DCC is currently the third largest mobile operator in Ukraine.
The agreement between Turkcell and DCC is finalized by the signing of the
contract, which enables the transfer of shares between the partners.

          THE TELECOMMUNICATION AUTHORITY FINES TURKCELL FOR VIOLATING
                            TURK TELEKOM'S MONOPOLY


 Subject: Statement made pursuant to Circular VIII, No: 39 of the
          Capital Markets Board.

Special Subjects:
-----------------


Although, the license agreement signed between Turkcell and the
Telecommunication Authority ("TA") allows Turkcell to establish necessary
infrastructure for the termination of both local and long distance voice traffic
and the monopoly of Turk Telekom has ended as of December 31, 2003, the TA has
fined Turkcell. The TA claims that Turkcell has violated its license agreement
by using infrastructure other than Turk Telekom's for its services. The fine
totals TL31,730,818,040,000 (approximately US$24.3mn as of April 5, 2004).

Turkcell will take the necessary legal actions against the TA's ruling.
