Cell mast handovers can occur even while stationary. It doesn’t only handover because of movement, but also other factors like capacity

Using 4G only made no difference to me
I'm going back to iOS 17 for now. As much as I'm looking forward to iOS 18, a phone has to work as a phone, lol.
 
I have been having this issue both on iOS 18 beta 4 and iOS 18.1 beta 1. Cellular dropping out numerous of times when commuting back and forth to the office. Tried to change over to only 4G and that solved the issue. Using Telenor in Norway.

Sorry, spoke too soon,

It still drops out after being on hold for 30 minutes and speaking to someone it cut out !
 
Someone on reddit claims turning off RCS helps with cellular issues. Not something I‘m willing to sacrifice though …

I don’t even have RCS as an option (in France), but the signal was still going wild on PB2. Seems to be doing better after switching to 4G from 5G Auto.

Update after a longish drive from France to Switzerland this morning.

Set off with 4G only selected in Data, no issues whatsoever (no dropouts) for about 1h20 while in France. As soon as I entered Switzerland, however and the iPhone went into a roaming mode, I had about 7 dropouts in a space of 10 minutes (still on 4G).

So to me 5G or 4G did not seem to make a difference and the fact that the problems started with roaming made me think that it might have something to do with a cellular service provider’s modem profile (or whatever it is called). Sure enough, the Swiss profile (58.5.10) was older than the one used by my native French provider (58.6). This can explain why some of us have the dropouts and others do not.

Edit: still cannot quite figure out the pattern, as sometimes I have separate drop-outs for either of my two lines and sometimes - for both of them. Hopefully the next beta sorts them out.

Having the issue here on EE (UK) too. At home it’s not too bad and drops out very infrequently.

Just been to Gateshead and it was dropping out every few seconds for about 10 minutes until it eventually settled, my phone got a bit warm whilst it was doing this too.

It dropped out on the drive home once too.
 
I'm on 18.1 with AI functions and unfortunately Cellular issue is still present, and there is no patern when it disapear. it's completly random... we need to wait for another build...18.0b5 as well 18.1b2
