IOS 14.5 Creating Signal & 4G Loss

I have recently upgraded my IPhone X’s IOS to 14.5 from 14.2.2 and since then I am having signal loss randomly along with 4G Cellular Data loss. I have tried hard/soft reset, airplane mode on/off, changing to 3G/4G but all results to temporary solution.

I try to call someone or send an SMS, but it fails to send/call. Then clears all the signal bars, starts searching for a signal, picks up a signal and then I try again and it works.

Then sometime later, I see that signal bars are all cleared again Nd I have no reception.
  • I have tried same SIM Card on Iphone 8 IOS 14.2.2 and no problem.

Does it occur when you move or also when you stand still ?

Such problems were reported on iPhone 12, when switching between reception towers:

It happens when I am in the same house, same room.
