No apps, no hassle
You don't have to download an app. All you need to do is make sure your phone is connected to a WiFi network.
No change to your bill
Calls using WiFi Calling will be charged at standard rates, just like any other calls or texts you make.
Make calls as usual
Just use your phone as you normally would. If you're out of network coverage, WiFi Calling lets you call or text.
Only connect once
Once you've connected to a WiFi network, you'll automatically connect to that network next time round.
