MOSCOW, July 31 (RAPSI) – The Federal Antimonopoly Service (FAS) has launched a case against four top Russian mobile operators over alleged violation of competition legislation, deputy head of the watchdog Anatoly Golomolzin said during the FAS press conference on Monday.

Earlier this month, the watchdog announced that actions of MTS, MegaFon, VimpelCom (Beeline brand) and T2 Mobile (Tele2 brand) may have violated the competition law by setting different prices for mobile phone service in customer’s home region and in roaming on the territory of Russia.

The watchdog issued warnings to the mobile operators prompting them to eliminate unreasonable difference in prices within two weeks.
