The most recent iOS 9 beta added WiFi calling options for AT&T subscribers, but when the beta was released last week, the feature was not functional.

As of today, some users in the MacRumors forums who are running iOS 9 noticed a different message when attempting to activate the feature, and just hours later, WiFi calling began working for a limited number of AT&T subscribers.

When attempting to activate WiFi calling in the Settings app, users who have access to the feature are receiving a welcome screen, a disclaimer, and a notice that WiFi calling has been activated and should be available within a few minutes. During the setup period, users are required to enter an address that emergency services will visit as a caller's location cannot be determined from a WiFi call.


Following a short waiting period, WiFi calling becomes ready for use with the "Wi-Fi calling on This iPhone" option toggled on. While a few of our readers have had success getting the WiFi calling feature working, several other users do not have access, suggesting AT&T may be testing the feature in a limited number of areas ahead of launch.


WiFi calling was first introduced with iOS 8, and shortly after the feature debuted, AT&T announced plans to support it. The company has not made any further announcements, but it is likely an official launch will come after iOS 9 is released to the public in September. An AT&T employee who is also a MacRumors reader says that his store has not received word on an upcoming launch, so official word on further availability of WiFi calling may still be a few weeks off.

WiFi calling is a feature that lets calls be placed over a wireless connection when cellular connectivity is poor. It is similar in function to Apple's own FaceTime audio feature, and has thus far been limited to T-Mobile and Sprint users.

I wonder how the performance is compared to their MicroCell. Can anybody weigh in with their experience after they've tried it?

Come on Verizon... This would be so handy at work where there is literally no reception in 80% of the building, yet wifi throughout...
Hopefully your work doesn't block most Internet access like mine does. lol If it's not HTTP or HTTPS, it's pretty much blocked.

mine keeps showing it then canceling it. It says "Oops" then it goes thru the second time, but fails back to "Oops"! :(

Welcome to 2006!

On a more serious note, I wonder if AT&T will end up charging for this?

I assume it will go through the billing system for international calling but I don't think they will charge for the ability to use the service. HDVoice is required and already charge for that.

Does anybody know why this is only enabled for iPhones 5c, 5s and newer? I'm assuming it must be a hardware-based deficiency in my iPhone 5.
The initial rollout from Apple perspective is iPhone 6 only, I hope that my iPhone 5s has the hardware to support WIFI Calling.

Wonder if it'll be able to be activated via carrier update like with T-Mobile. When they launched it, it just popped up and said I had a carrier update then I had the screen availability like the pics above show.

Finally a reason to risk putting iOS 9 Beta on my main phone.

Is this working for anyone in the Miami, FL area yet? Wonder if it's by area, or just random.
