No signal after iOS 18

I did the security update of iOS 17.7.1

Then I waited for the iOS18.0.1 and after that I cant make calls or use 4G/5G. After the 18.1 still the same.

No sim working on my device but all 3 i tried working on other devices

I tried restart, on/off airplane mode, reset network connections. I did format the phone clean and with backup but still no calls.

After the format 5G is working slowly but it stops when i try to make a call or someone is calling.
