Hi
I recently updated my Samsung Galaxy M34 5G to One UI 8 and started facing network issues. 
I am not able to call anyone neither receiving any call. If someone is calling it is saying number is out of reach of not available.
I tried resetting network several times and that will solve my problem for 5 minutes and after that same issue persist, tried resetting my entire phone then it worked fine for 3-4 hours and again the same.
Is anyone facing the same issue?
Any idea how can I revert back to One UI 7 back again.

Hi
It is not showing any error message, just I am not able to call anyone neither receive any call.
Internet is not working. It is not showing any error log or message.
I have connected to chat support but they also didn't help with anything, they are suggesting to go to nearest Service Centre and that is bit far fromy place and festival is also there so can't go now.
