Hi guys,
I've my S21 Ultra having Mobile Network issues since almost two weeks.
I saw it is something that happen to other users. But, how to solve?
I tried changing Sim card, etc.. The issue is clearly the smartphone.

Any idea?

Thank you.

Not sure what problem you've experienced but I sometimes got Not Registerd On Netowork problem and reseting the phone temporarily fixed the problem and I'd say its probably the phone but I'm not too sure in your case

Hey there

Other users have found success for this issue by performing a Reset Mobile Network Settings.

It won't delete your data.

Basically it's a hardware issue with the phone.. mine went in 3 times, each occasion I was fobbed off by the service centre.. at the end I traded it in..

So what is the solution?

I saw different users complaining about this problem since about two weeks, but not a word by samsung itself.

A reset of the network doesnt work. Going in Offline Mode solves for just few seconds. 

Reboot doesnt solve.

The smartphone is pretty new. It is ridiculous to have this problem with a high-grade smartphone.

I might have the same issue with my Samsung Galaxy S21 5G. For the last couple of weeks my mobile network has been acting weird by not always sending/receiving mms and not updating some app feeds sometimes.
