TURKCELL PROVIDES UPDATE ON NATIONAL ROAMING DISPUTE

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

Istanbul Stock Exchange

ISTANBUL

Special Subjects:

Previously, Turkcell announced that The Telecommunication Authority (“TA”) had fined the Company, claiming that Turkcell had not complied with its responsibility under Turkish regulations (Telegram and Telephone Law number 406, Article: 10) to provide national roaming. Accordingly, Turkcell was charged a fine of TL21,822,150,300,000 (approximately US$15.3mn as of November 30, 2004). Turkcell paid the fine in April 2004, and subsequently commenced legal actions against the TA’s ruling, in addition to seeking an injunction to cease implementation of the Regulation issued by TA regarding national roaming.

In response to the lawsuit filed by Turkcell regarding the TA’s decision, the 10th Chamber of the Council of State in Turkey has issued an injunction to cease the decisions and actions that are the subject of a lawsuit until the case is finalized, but rejected Turkcell’s request for an injunction to cease implementation of the Regulation regarding national roaming. Although the case still continued, as of January 2005, Telecommunications Authority paid back TRY 21,822 (approximately US$16.6 million as of February 23, 2006) with respect to the aforesaid injunction.

Now, the above mentioned case has been concluded and the Council of State in Turkey annulled the TA’s decision imposing fine on our Company but rejected Turkcell’s request to annul the regulation regarding national roaming.

We hereby confirm that the above-mentioned explanations are furnished as per the provisions of the Communiqué Serial no VIII/39, that they reflect all information we have gathered so far, that they are in accordance with our corporate documents, that we have used all endeavours to collect the complete and true related information and that we assume the responsibility for this disclosure.
