Solved: Wifi calling disappeared

Reefraider · ‎31-12-2020

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.

I downloaded the update as normal then once download was complete I popped the sim out the top of the phone. Then I started the update to my phone. then when the phone restarted I reinserted the sim. Now when I restart my phone the WiFi calling reappears on its own. Now I know its a bit late since you've updated your phone but try this at the next update. I hope this helps my fingers are crossed for you.

If you've updated already turn phone off, eject sim then turn on phone and reinsert sim you should get WiFi calling back. If not restart phone and it should appear.

This was for an S20 ultra so may work for S21, let me know.

Cheers Ian

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.
