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?

Still no solution? I cannot believe this. I am doing the 190th reply and still no solution NOR AN APPROPRIATE REPLY FROM Samsung mods.
My phone cant be used, this is so frustrating.
My biggest issue is that I do not get notified of any missed call while the connection is lost. Zero. And people calling me do NOT get the usual "the number you have dialed is not available", but rather no signal / message / feedback at all

I understand how very frustrating it is... 

They need to recall the phones. Like how many more folks phones going go down. Especially with new updates. I am scared to he'll and back to do any updates. I even have chrome needing to do update but I'm like he'll no. Idk how my phone just " started" working normal again. All I know is I didn't have 400$ to upgrade to the 22. Which I'm hearing has issues to. When I pay this off as much I love my galaxy and boy do I ever unless Samsung starts better maintenance with on call tech which btw was not a bad one... I used the chat there was nothing more than what trained in and get a ticket order to send off. 

I am just astounded at even w warranty and free upgrade I still have come outta pocket. 

As explained to me now days free upgrades are no longer the phones they are the memory sizes. Heck if I could get extra insurance coverage that be great! If your Sim works I think I'd just buy me a different phone style that's what I was gonna do if mine was broke for long was.

I am having the same issue, had my phone sent back to samsung to check it out, who replaced the sub board/ charging port. Made no difference. Good to know i am not alone.

Finally, after 4 rounds of failed repair attempts my phone was judged to be unrepairable and I will get a PARTIAL refund.

Goodbye Samsung, good luck to you guys!

The MAINboard needs to be replaced!!!!!!

To solve it go to setting- connection -mobile network- turn off Volte Calls sim 1 or 2 ( this is causing the issue) and for network select LTE/3g/2g.

Sorry to tell you that but this is total B.S. I have tried this method but it did fix the issue. THE ONLY SOLUTION IS TO REPLACE THE MAIN BOARD 

[medonalo]

I agree this is one of the worst phones I have ever bought, but this was the only solution in my case, and it's working fine for me.

If I can delete my reply because you are right, the issue accrued again 😁😁😁😁

[Khunter76]

Wouldn't worked for my situation.. If you re read my post on my issues I had no Data issues. So z downloading or using airplane mode was obsolete. I hate that everyone is having issues.  Oh BTW yall remember how G7 edges screens where? They rolled in corners very little protection if dropped. Well, guess what they did it to 22! Man, i tell you what, crazy design and cost will be high
