Wi-Fi Calling lets you make and receive calls over Wi-Fi when your mobile signal is weak or unavailable.
If you’re having problems, make sure Wi-Fi Calling is on in your phone settings. You also need to be connected to a Wi-Fi network that supports voice calls.
Wi-Fi Calling only works in the UK. It doesn’t work abroad.
I have a compatible device, but don't see a "Wi-Fi Calling" setting in my menu
You may need to update your phone's software to the latest version.
Check how to do this for your phone.
If you're using Wi-Fi Calling for the first time, you may need to switch off your phone and turn it back on before you see the 'Wi-Fi Calling' indicator.
Connected to Wi-Fi, but don't see the Wi-Fi Call indicator?
If your Wi-Fi signal isn't strong enough or can't support a voice call, your phone won't show the "Wi-Fi Call" indicator. This can sometimes happen over busy connections.
If you get this problem at home, it may be due to a problem with your internet connection. Start by checking if you can access the internet on your phone or other devices.

Poor quality calls?
To use Wi-Fi Calling, we recommend a connection speed of 1mbps (megabits per second). If you've still got problems, it could be because your broadband isn't fast enough, or because you're using up your bandwidth by streaming films at the same time.
If you're on public Wi-Fi with many other users, congestion or low bandwidth may affect call quality. You may need to check you're logged in correctly to access the Wi-Fi - not all public Wi-Fi hotspots will keep you logged in. If you continue to experience poor connection, we recommend turning off Wi-Fi Calling.
Can't change settings for Call Waiting, Call Forwarding or Withhold Number
You can't activate these three services while on Wi-Fi Calling or without a mobile signal. The best thing is to set them up beforehand, and they'll work as usual. You can't deactivate Call Forwarding while you're using Wi-Fi Calling, even when network coverage is available.
