I have exactly the same problem, since installing iOS 18 Beta 4 the network loss problem is very common. I also noticed that this problem occurs in motion when the device switches between transmitters. The latest update iOS 18 Beta 4.5 changed nothing at all. I will only add that the problem occurs in Poland, I hope it is only a matter of the new update and not some damage to the modem.

I have the same problem, when I'm on the move the phone changes the transmitter every few seconds, iOS 18.4 has broken something in this regard and the worst thing is that even iOS 18.1 has not fixed it in any way
