After being promised Wi-Fi calling for over a yr by Apple and AT&T…it’s lastly right here.
It’s obtainable for iPhone 6, 6+ and 6S and 6S+ AT&T clients with iOS 9. You’ll need to go to your phone’s settings (Settings > Telephone) and flip it on manually:
You’ll then need to enter in an emergency tackle in case you’re ever in want of help. Wi-Fi isn’t as traceable as your mobile connection, so in the event you have been to name 911, AT&T wants the additional info to determine you.
The feature is sort of useful when you could have a Wi-Fi connection however your cell connection sucks. The phone will change over to Wi-Fi mechanically.
