Hi, I have a S21 Ultra since late January, I had issues in the past but now since the last Update 3 days ago My Mobile Network stopped working, I have an (Ø) symbol not even empty bars, the SIM card works great on other devices, but non SIM card works on this device, I tried reseting the network settings, Wiped cache partition, factory reset, airplane mode on and Off, looks like the antenna stopped working completely, not a single SIM card works on this device.
I have Wifi connection but is not what I bought this phone for, I want network service, is there any other solution I can try?
Solved! Go to Solution.

It seems to be a hardware issue. A mainboard replacement is the only fix.

Yesterday my phone updated itself to Android 12 and both sims started to disconnect randomly, even during phone calls.
Is there any way to restore the previous version? I bought this phone in Italy three months ago...

Hi i am from UAE,
i faced the similar issue no signals after Dec update. I took the phone to one of the service center, they flash the phone and installed software again, now its working fine. But i lost all the data 😞

This won't help. Please go back to the service centre and ask them to replace your mainboard.
