Samsung S23 Ultra connection issue no signal

[Bluesocks]

I upgraded to a Samsung S23 Ultra a few weeks ago and have just set up the phone in the last few days but away from WiFi there is no signal. I have 2 different network sim cards in and both show no connection. When within WiFi if I toggle settings it returns but as soon as I leave the house both shut off with a circle icon with a diagonal line through so it is of absolute no use to me. I have tried numerous suggestions from here and also factory reset twice. The same issue remains. 

I see many posts on here showing the same problem which seems to link to an issue with an update?

I have an appointment with EE tomorrow to see what they say about the issue. If anyone can advise further please do?

I disabled 5G and it seems to be stable now (i.e. set network mode to 4G/3G/2G)

I had the same issue for the last two weeks. the signal show only one bar at best ( 0 bar the rest of the time) I

tried reseting the network settuings as suggested above with no success. god I hate samsung and their shitty product + awful customer support

Between dead display in pristine condition that they dont cover under warranty due to invisible crack inside, Zfold 4 hinge that fail to close after 6 month again "not under warranty" and now that : screw that company.

Install Phone by Google 54.0.330599332 or any other version from 2020 on your S23Ultra. Dial *#*#4636#*#*. Change to any nerwork mode you want. You can force LTE(4g) only NR(5g) only or whatever.

I have the same issue also, it's also depends on where you are, for example in the city center it works and I got signal, but in some places even outdoor I don't got signal. I want to return the phone since it still in the warranty but I am not sure if it's a software or hardware problem.

has anyone found a fix for this? I have tried factory reset, switching from physical sim to eSim works periodically but most of the time when not connected to wifi has no signal with a line through it.
