Far be it from humble Android bloggers to tell a multi-billion-dollar telecom corporation what to do with its nigh-infinite resources. But when you're rolling out something that your competitors have offered for some time, it's usually prudent to make it available to as many people as possible. That doesn't seem to be the case for AT&T's Wi-Fi calling feature. The first phone to get it is the Galaxy S7... no, wait, sorry, I made a mistake. That's the choice that would make sense. The first phone to get AT&T Wi-Fi calling is the LG G4.
Yeah, the G4, LG's flagship model from last year. It's a fine device, and given LG's radical shift towards an awkward modular design it might even be preferable to the G5 for some users. But it's still an inexplicable choice for AT&T, which supports almost every major flagship from this year and probably wants to sell you a new G5, or a Galaxy S7, or even an HTC 10 if they're feeling bold. Why roll out Wi-Fi calling, which is quite a desirable feature for anyone who can't get a crystal-clear cellular connection in their phone or office, to a year-old phone to start with?
AT&T Wi-Fi calling requires a post-paid account, and it's only available on carrier-branded phones (so you can't bring your unlocked G4 to the party). Before today the feature was only available on iPhones on AT&T, but it should be rolling out to more Android phones in the future. Probably. Maybe. Who knows. The next one to get it might be the Kyocera DuraForce or something.
