(RIA Novosti) - Mobile TeleSystems, VimpelCom and MegaFon are facing action from Russia's Anti-Monopoly Service.
The service said Thursday it was moving against the country's three biggest mobile operators in the wake of a check into new tariffs used by them for mutual settlements, below the rates set for other mobile operators, reports Trend.
It said the "big three" were using a rate of 0.95 rubles ($0.0351) per connection, whereas other operators had to pay 1.1 rubles ($0.037) for the same service, or 16% more, which put them at a disadvantage.
It said regional operators and operators entering the mobile services market were in an unequal position compared with the established federal operators, which breached anti-monopoly laws.
The case will be heard on September 28.
