S21 Ultra No Network Conection after the last Update

[Juan greenfield]

Hi, I have a S21 Ultra since late January, I had issues in the past but now since the last Update 3 days ago My Mobile Network stopped working, I have an (Ø) symbol not even empty bars, the SIM card works great on other devices, but non SIM card works on this device, I tried reseting the network settings, Wiped cache partition, factory reset, airplane mode on and Off, looks like the antenna stopped working completely, not a single SIM card works on this device.

I have Wifi connection but is not what I bought this phone for, I want network service, is there any other solution I can try?

Can you describe your exact problem in more detail...? Did this happen right after the July update...?

[tploumen]

It would be nice if Samsung could acknowledge the problem and could tell us if they are working on a software fix.

[Nattyrubynat]

Did you solve the problem? 

[tploumen]

No, and you...?

[tploumen]

Did anyone fix the problem already...??

I got security pach october but nothing changed i still have no signal. I will wait for ui4.0 if hat doesnt help then i'll change carrier. After that i will switch samsung forever, this is ridiculous in 2021 i dont have 4g and people cant call me. Does anyone know how to contach google support except email or live chat

Exactly the same mate. I installed the october patch yesterday, but still no signal issues with 4g 😞

Can you give me your exact model number...? Mine is: SM-G998BZTHEUB.

I'm asking this because maybe we are in a bad hardware batch.

SM-G998B/DS

I need to know the full number (you can see it in your order receipt) or read in on the box. Because there different versions like 256 Gb, 512 Gb etc.
