Telefónica Móviles’ Ecuadorean unit Movistar Ecuador has announced the launch of new services based on GSM technology following a successful two-month trial in the cities of Quito, Guayaquil and Cuenca. Historically, Movistar has relied on TDMA and CDMA technologies to deliver its services, but has now opted for GSM to take advantage of the introduction of number portability and to be able to offer low cost handsets. Until now rival operator Porta, owned by América Móvil, has been the sole champion of GSM in Ecuador. It boasts around 3.38 million users and leads the pack with a 65% share of the country’s 5.2 million mobile subscribers. The country’s third operator Alegro PCS operates a CDMA network.
