Wi-Fi Calling On T-Mobile Android Phones Coming Soon

T-Mobile has announced that their full line up of Android handsets, including the recently announced Motorola Defy will soon get the ability to natively make Wi-Fi-based voice calls. The functionality should help users save a lot of calling minutes as they can alternately call over Wi-Fi. T-Mobile has said that the carrier’s solution would be based on the Kineto‚Äôs Smart Wi-Fi Application and on devices that come pre-installed with the Wi-Fi calling system, the service will work out of the box. T-Mobile is expected to offer complete tutorial to users who are not aware about the Wi-Fi calling functionality.

This is a pretty interesting move considering that T-Mobile could be shooting itself in the foot by trading paid calling minutes for free Wi-Fi calls. However, what T-Mobile could be betting on is the fact that this option could push a lot of new subscribers to migrate from their feature phones to a more sophisticated Android phone that could also bring in greater moolah on a monthly basis. Also, since Wi-Fi calling is not possible under all circumstances, T-Mobile should not be expecting a very significant drop in ARPU either.
