T-Mobile has confirmed what the rumor mill had already established as almost definite: Android phones on the network will start getting WiFi-calling capability. Formerly known as UMA — that branding seems to have been stripped in this latest push — WiFi calling allows users with compatible plans to save their minutes / messages by calling and texting over wireless networks. The first two Android phones to be endowed with this feature will be the T-Mobile myTouch and Motorola Defy, with a trio of BlackBerries (Curve 8520, Curve 3G, and Bold 9700) and the Nokia E73 Mode already able to tap into the functionality.
T-Mobile has been offering its UMA service since 2007, although it has gone mostly under-the-radar until this recent announcement, with Android support bound to bring many more users into the fold. It’s likely that both the unannounced Motorola Cliq 2 and LG Optimus will ship with WiFi calling as well.
