Wi-Fi Calling is a great feature by Apple launched in iOS 9, which is exclusive to the iPhone 6 and 6 Plus, allows users to place cellular calls over a Wi-Fi network in situations where they have a poor cell signal. Course the Wi-Fi Calling must get the support of carriers, such as its first supporter AT&T.
Although iOS 9 public not yet officially released, but there have been some of developers and users are testing iOS 9 beta on their device. And some AT&T subscribers have received a prompt about ‘Enabling Wi-Fi calling’, once they enabled this feature, they will be able to make cellular calls from their iPhone 6 and / or iPhone 6 Plus on a Wi-Fi network, when the cell signal is not strong enough to handle the call.
How to Setup Wi-Fi calling and Find out If It’s Currently Available in Your Area.
To turn on Wi-Fi Calling, go to the Phone panel in the Settings app and select the Wi-Fi Calling option. It should be at the top of the second section, just below “My Number.” On this page you’ll find a single toggle. Turn that on to begin the setup process. You’ll be given some basic privacy information and asked if you want to continue.
At this point, the beta used to simply return an error message, but with the changes on AT&T’s side today, you’ll now see a lengthy a agreement that you’ll need to accept before you can proceed. It gives warnings about potential issues with 911 calls and some boilerplate disclaimers.
Once you’ve agreed to the terms, you’ll be told whether the feature is available in your area. If it is, you should start seeing it work over the next few minutes. If not, you’ll need to wait until AT&T enables it for your market.
