Wifi calling disappeared

[Reefraider]

I'm on o2 and since latest ui update wifi calling has mysteriously disappeared was there Wednesday because I called my mother using it. Any help gratefully received.

This is a known issue on the U.K. carrier, O2. 

See... wifi calling for a possible solution.

same issue with the Note now since android 11. can't see how it's o2 fault when it was working perfectly fine. I now have to remove the sim and put it back in every time I restart the phone so WiFi calling kicks in again

Same with me and it's been getting very annoying never had this problem before the update so I'm guessing it was the last update that started this problem. And I am wondering if its just o2 that it's affecting! So guessing that it may be a Samsung software glitch.

The Wi-fi calling issue appears to affect all the S20 devices on the U.K's O2 network. Devices like my own on the unbranded, BTU, firmware are not seeing this problem on non O2 networks.

This is a non branded s20 on the o2 network,

Correct... as I stated in my previous post...

"The Wi-fi calling issue appears to affect all the S20 devices on the U.K's O2 network. Devices like my own on the unbranded, BTU, firmware are not seeing this problem on non O2 networks."

This would indicate that O2 is the problem.
