Cellcos shut down AMPS/TDMA services

26 Jul 2007

Ecuadorian mobile operator Porta plans to shut down its AMPS/TDMA network by 30 September 2007, according to a statement by regulator Suptel, quoted by BNamericas. Porta, owned by Mexico’s América Móvil, is in the process of migrating its client base from TDMA to GSM technology. Rival cellco Movistar Ecuador also plans to shut down its AMPS/TDMA network on 31 December 2008. The company, a unit of Spanish giant Telefónica, has already stopped marketing new AMPS/TDMA connections and is aggressively encouraging a migration to GSM.
