MTS Announces New Appointments
and Changes to its Management Structure


Moscow, Russian Federation – October 3, 2005 – Mobile TeleSystems OJSC (“MTS” - NYSE: MBT), the largest mobile phone operator in Russia and the CIS, enters a new phase in the optimization of the Company’s management structure and announces the creation of a number of new management positions.


Mr. Eric Franke, previously Director General of Ukrainian Mobile Communications (UMC), a 100%-owned subsidiary of MTS in Ukraine, has been appointed First Vice-President and COO of MTS. His responsibilities will include managing a number of the Company’s operating functions - Technical Strategy and Development, Information Technology (IT) and Logistics.


Mr. Eric Franke assumes his new position from October 3, 2005. Mr. Adam Wojacki, UMC’s Deputy Director General and Director of Marketing, will serve as Acting Director General of UMC.


Mr. Mikhail Shamolin has been appointed Vice-President for Sales and Customer Service. He will be in charge of managing the Sales and Customer Service division and be responsible for MTS’ Russian macro-regional business units.


The Corporate Development and Strategy functions have been integrated into one division. Ms. Tatiana Evtushenkova, previously Vice-President for Investments and Corporate Development, has been appointed Vice-President for Strategy and Corporate Development.


Mr. Dmitry Prokhorenko, previously Director of Human Resources (HR) at MTS, has been appointed Vice-President for Human Resources. Raising the status of the HR division highlights the importance placed by the Company on applying an efficient staffing policy and implementing uniform talent management standards at MTS.


These new positions have been created within the framework of the management optimization program initiated in 2003. A vital stage of this program was the implementation of a three-tiered management structure comprising of the Corporate Center, Macro-Regional and Regional business units, as well as a greater degree of centralization in such key functions as Strategy, Marketing, Sales and Customer Service, Technical, IT, and Finance and Investments. The most recent changes are aimed at bringing the Company’s management structure in line with its key business priorities.


“The changes in the management structure are due to the further implementation of the management optimization program and are aimed at further strengthening MTS’ leadership position in its markets of operation. The appointments of Eric Franke and Mikhail Shamolin bring additional talent and professional knowledge to our management team,” highlighted MTS’ President and CEO, Vassily Sidorov.
