One UI 5.1 update has messed up my A52

After downloading One UI 5.1 update on my Galaxy A52 (5G) I could not make or receive calls, the Sim Manager says my mobile number is unknown. I have rebooted, cleared the cache partition and reset to factory settings, but the update is still in the operating system and I can't make calls. It works on Wifi and all the apps are fine. Tried another  Network Sim card and it doesn't recognize it, looks like I'll have to buy another phone, Cheers, Pete

Who is network provider? Contact them if you can't make calls. Once you carry out the update you can't revert back to the original one.

That's at your own risk, flashing firmware. Is it really worth it.

@Scadz  Did you reset the Network connections, Settings-General Management-Reset Network Settings (Wifi,Mobile,Bluetooth)  Some other advice here https://www.guidingtech.com/fix-android-not-making-or-receiving-calls/  if still no solution  contact your Network provider in the first instance,   if by any chance no joy there contact Samsung Support or visit  a Samsung service centre.

I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.

To cut a long story short, I took my mobile back to Curry's, it was still under warranty, the tech said it was a bug in the update. He found a newer update, downloaded it and that sorted it out. Thank you for all your suggestions and support.
