Wifi calling has stopped working, IMS has changed to 'Not Registered' the service was working fine before hand, getting in touch with o2 is quite a chore to get it sorted.
Phone has the latest update One UI 3.0, Android 11
Could it possibly be due to out of date carrier settings?
Solved! Go to Solution.
Thanks for the swift response Cleoriff, I did already try that. Do you mean insert the sim whilst the phone is powered on or turn it off again?
Edit: I tried that, and it worked straight away. Really appreciate the help!
Just seen your edit. Pleased it's now working @Mattyw
