T-Mobile Tests GSM/Wi-Fi Service in Seattle

T-Mobile USA began testing a fixed-mobile convergence (FMC) service in Seattle that lets callers roam between its GSM network and a Wi-Fi network. The trial service, which is priced at $20 per month for subscribers with monthly packages of $40 or more, lets users make unlimited, nationwide calls using a home Wi-Fi router without using airtime plan minutes. It also enables unlimited calling from T-Mobile hotspot locations.
