S22 Ultra "not on registered network"

[edavis1003]

On 5/26, my S22 Ultra suddenly disconnected from the network. Even though it showed bars and 5G, I was unable to make calls. Occasionally, it showed "no service" at the top and a notification that "your phone's not on a registered network, so you can only make emergency calls." After a Google search, I tried:

1. Phone restart

2. Airplane mode off and on

3. Software is up to date 

4. Removed SIM, wiped down, reinserted

5. Another SIM

6. Reset network settings

7. Toggled SIM on & off

8. Factory reset

Then: 

9. AT&T, 2 different stores over 3 visits - every time I was in the store, it connected. But it clearly was not a network issue, so they could only offer replacement by insurance or trade in

10. Geek Squad - offered replacement, same as AT&T

11. uBreakiFix - offered to replace parts, but stated 70% of the time, it is a software error, and the phone must be replaced anyway. 

I can't find any information on Samsung recognizing the issue, which seems to be quite widespread over the past year & including S23 Ultra, and offering replacement. I am out of warranty, and my extended warranty with All State has expired. 

Are we going to get a class action lawsuit? Sign me up.

Do you have AT&T as your phone carrier?

[edavis1003]

Yes

Then all they have to do is register your phone number onto the mobile network. My phone carrier already has deactivated my phone number because I kept getting the exact same notifications.

It sounds like you are having antennae issues on your S22U. The only way to solve this is through a Samsung authorized service center. They will know exactly how to fix this issue.

Ever since May 25th/26th and the most recent update, my S22 Ultra cannot get Registered to a Newtork. I have tried everything both Samsung and my carrier (T Mobile) have suggested. On/Off, Airplane Mode, Manual Network remove adds, Resets, remove and reinster SIM. clean SIM, get an E-Sim. 

So far both T Mobile and Samsung said it's a known issue but I was wondering if anyone found a fix for this issue?

Samsung Team - please don't give me the generic routine (try this this and this), as we have all tried your suggestions and nothing is working. Obviuosly it is an update issue and even with the new update this morning, it is still occurring.

Thanks in advance!

My phone number is deactivated right now. All T-Mobile has to do is register your phone number onto the mobile network and you should be all set.

Thank you. Is it still deactivated or were they able to get you back on line? Do I have to go in store or can I call them? I will try and give it a try.
