LONDON, 09 February, 2011 – Mobile TeleSystems OJSC (“MTS” - NYSE: MBT), the leading telecommunications operator in Russia and the CIS, has recently announced the launch of MTS Navigator, its highly advanced personal search, mapping and navigation solution powered by Telmap on the iPhone.

The service is now available for free to all MTS’ iPhone users.

MTS Navigator, powered by Telmap, provides full Russian language support and includes in-car navigation with 3D moving maps, turn-by-turn voice instructions that announce street names, a dedicated pedestrian mode, and access to thousands of points of interest across Russia such as gas stations, parking lots, restaurants, bars, hotels and more. It is specifically designed to enrich users’ on-the-go experiences, beyond in-car and pedestrian navigation.

“We are exhilarated that MTS is joining more and more tier-1 operators across EMEA who see the value in providing users with free search, mapping and local search. We believe that providing an excellent local search, mapping and navigation service free of charge will turn out as a win-win proposition as it will be expanded to a full mobile location companion, serving all users’ needs while on the go, from real-time traffic, speed cameras alerts to location-enabled social interactions and relevant commercial offers”, says Oren Nissim, Telmap CEO.

“The free offering of MTS Navigator to our iPhone users is part of our overall strategy of providing an excellent, comprehensive set of location-based services to our subscribers, putting them in the center and striving to anticipate and cater for all their on-the-go needs in a smooth, user-friendly way“, said Mikhail Gerchuk, MTS Vice-President and Chief Commercial Officer.
