Outgoing Russian President Dmitry Medvedev has called for rules to be put in place to allow domestic mobile phone users to retain their existing numbers after changing service provider, RIA Novosti reports. TeleGeography’s GlobalComms Database notes that the Russian government has been attempting to implement mobile number portability (MNP) since 2005, when it initially floated the idea. In October 2009 the ministry discussed NP implementation with all main players, with most opposing the proposal: according to Mobile TeleSystems (MTS) the modification of its IT systems would cost it USD127 million, while it estimated that across the industry, costs could amount to USD500 million. Further, MTS said its research showed that a maximum of 2% of subscribers would use the service, a view apparently echoed by Vimpelcom. Medvedev’s demand follows a meeting with Igor Artemyev, the head of the Federal Antimonopoly Service (FAS), who urged: ‘We can simply use [state] power. Mobile operators’ costs will be minimal’.
