Ecuadorian mobile operator Movistar, owned by Spain’s Telefónica, plans to shut down its AMPS/TDMA network on 31 December 2008, according to a statement from regulator Suptel. The cellco has stopped marketing and activating new TDMA connections, and is aggressively migrating its users to its GSM network, the watchdog added. The AMPS/TDMA network has been operational since 1993 and once it is shut down Movistar will be able to optimise its CDMA and GSM spectrum, Suptel said. According to TeleGeography’s GlobalComms database, Movistar added commercial GSM services to its portfolio in September 2005, and by the end of 2006 its subscriber mix was 51.5% GSM, 43.3% CDMA and 5.2% TDMA. It reported a total of 2,480,100 subscribers at the end of March 2007, giving it a 28% market share.
