iOS 8 WiFi Calling: Here's Which Carriers Will Offer It

WiFi calling is one of the neat features available on iOS 8 and the iPhone 6, but not everyone is ready to make it happen for you. The function still needs carrier support, and that's not up to Apple. Now that the major carriers have chimed in, we get a full rundown of which support WiFi calling — and why you might not even care if they don't yet.

T-Mobile is clearly on-board, as they said over and over again at their Uncarrier event. They've even gone so far as to sell a router to make WiFi calling simpler while at home, so they're obviously excited about the technology.

AT&T and Verizon, they're not so excitable. The two largest carriers will support WiFi calling, but not until 2015. AT&T won't commit to a timeframe smaller than the entire year, only saying WiFi calling will hit "sometime" in 2015. Verizon isn't giving a hard timeframe, either, but now says it will come in mid-2015.

Verizon took a minute to subtly jab T-mobile in saying they weren't too worried about WiFi calling because "We built our voice platform so extensively [that] there was never a need for us to tell our customers, 'Oh, our network is not good enough so you need to go on Wi-Fi to complete your call.'"

Though WiFi calling is cool because it's basically free calls, it's really part of Apple's continuity features for iOS and OS X bliss. With OS X Yosemite and iOS 8, users can make and take calls over a WiFi signal. The iPhone is simply used as a backbone for the feature, which is reportedly not quite ready anyway.

Even with T-Mobile's rollout, things don't appear to be so smooth. The carrier seems to be having some issues with the feature, at least for the iPhone 5S and older.
