Sprint may join T-Mobile in offering free Wi-Fi calling for select Android smartphones in a bid to compete with the increasingly popular “Un-Carrier.” The latest rumor comes from an internal Sprint document leaked to Android Central, suggesting the service could launch on Samsung’s Galaxy S4 Mini and Galaxy Mega.
Calls made while your smartphone is connected to a Wi-Fi signal won’t count towards your allotted monthly voice minutes. One issue however, is that you won’t be able to switch back and forth between Sprint’s CDMA signal and Wi-Fi mid-call, meaning if you pick up the phone in your house or office you can’t go outside until you’re done talking. The service also requires you activate Android Location Services.
There’s no word on when the service will arrive, though Sprint’s apparent decision to limit it initially to the Galaxy S4 Mini and Mega suggests we’re likely looking at a slow initial launch with no promise of a carrier-wide rollout. Sprint declined to comment on the rumor when reached for comment by TechnoBuffalo.
