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.

I just did the latest update and my Galaxy A53 keeps crashing, freezing, restarting.

1. Wipe device cache in recovery. See this post for steps, as well as other post-update tips:

2. Download Good Guardians from the Galaxy Store and install & run the Galaxy App Booster module.

Why is samsung not responding to everyone? They definitely know about this S22 connectivity and dropped calls issues. They respond to every issue but this issue. Can they fix it already? It is the most inconvenient issue and costs all of us money when they ignore our issues. At this rate we shall move to Apple!

Exactly. I just got off the phone with att with the same problem

Exactly, i tried everything even a factory reset! I'm moving to apple now. Samsung wouldn't even reply on our inquiry! It's a shame because I really liked my S22 but this problem makes it unusable

I am having the same issues as well. I had never had any connectivity problems anywhere during my commutes and now, I am constantly loosing service.
