S22 Ultra "not on registered network"

edavis1003 — Fri, 30 May 2025 19:25:46 GMT

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?

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.

S22 Ultra Not Registered to a Network After Update

Members_bj4Kww7 — Fri, 30 May 2025 20:27:41 GMT

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.

It is still deactivated, yes. They haven't got me registered on the mobile network yet, but that's why it's deactivated right now. You can call them or go into your nearest T-Mobile store and tell them that your phone number is not registered on the mobile network and if there's a way that they can register it.

Ok cool. Thank you. I am on with them now doing the same thing I already did with them yesterday. I asked them to just register my phone on the network and they said they are seeing it on the network. I'll ask them again to just re-register it if they tell me there's nothing more they can do. I'll keep you posted.

I had this exact problem after I cleared cache partition. I had to call my company and they had to send me a new SIM card or a register a esim.. after that my problem was fixed.

I was just on the phone with both T Mobile and Samsung for over an hour and nothing. Samsung is expediting my case to an expert. In the meantime I just cleared the cache partition as you suggested but am still having the same issue. Do I need a new eSim afterwards for it to work?

Re: Re: S22 Ultra Not Registered to a Network After Update

Deezi — Fri, 30 May 2025 22:14:17 GMT

Yeah I did too.. he literally got to call T-Mobile back and tell them they have the reset your network to your SIM or give you an esim trust me

AHhh didn't work. Just got off the phone with my provider after clearing cache and nothing. Same issue with the phone not being registered. to the network.

Deezi — Fri, 30 May 2025 23:49:03 GMT

Yeah that's exactly what happened to me they literally had to open my account at T-Mobile and reset my whole account to an esim because my actual SIM got messed up after that
