OBS_VALUE: Mobile communication operators are not regulated as SMP unless they voluntarily file an application with the regulating authority to be considered as such and prove that they meet relevant criteria. Mobile segment is dominated by four operators: Megafon, Vympelkom, Tele2 and MTC. However, as on 2022, register of operators having significant market power in the field of communications does not contain mobile operators: http://rkn.gov.ru/communication/register/p197/. Rates are thus currently not regulated for the mobile operators.
