S21 Ultra No Network Conection after the last Update

[Juan greenfield]

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?

I read through the whole post. I gather most people a hardware swap was needed a very few had a software problem.  Mostly all happened after an update.  100% of the time samsung failed to fix the issue.

I have this exact same issue. This did not fix it.
