Wifi calling M31 android 10

[M315]

I am in uk and cannot find a setting to to turn wifi calling on . My network provides for  this . Have seen all sorts of videos but not for.uk .

Wi-Fi calling is available on devices from supporting Network Providers, @M315. If this was added on your phone when you purchased your phone from your Network provider, you'll be able to find thin the Phone app > 3 dots in top right > Settings.

Thanks for that but as I have sim only from my Network provider and bought the phone myself ,elsewhere  , perhaps that is the problem . The Samsung M31 is not listed on their help page .

I too have this issue. in the UK the Samsung M31 was an Amazon only purchase and my provider (Vodafone) do support WiFi calling, which this SIM was using on another phone previously.
All wifi calling options seem to be missing from the UI.
I was hoping for a change on the Android 11 update !!
