iOS 14 no signal, no cellular data

Hi!
I've installed iOS beta 4 on my iPhone 11 Pro and since then, I lost the signal and I don't have data. I have another iPhone X with iOS 14, and I don't have issue with it. It only occurs on iPhone 11.

I tried many things like:
  • Reset network setting

  • Turn off/on airplane mode

  • Turn off/on cellular data

  • Hard reboot

  • Soft reboot

  • Reset content and data

  • Turn off/on roaming

...
Same issues
It seems that the cell is looking for the signal constantly.

Do you have any idea how to fix it ?
