S22 ultra network issue driving me crazy

[Middyman83]

So updated my phone. Worked fine for a few days then I suddenly seen emergency calls only. Tried force reset, tried safe mode clear cache. Nothing helped. Turn on wifi and it pickups the network carrier and works fine.

Tried the sim card in another phone works perfectly fine. Tried another sim card from my husbands number with a different carrier and it worked fine without wifi on. 

So my sim card with my carrier isn't working on my phone. The sim isn't fault. The phones antenna is fine as I mentioned different with a different carrier worked fine. 

I cant use my phone with my carrier unless wifi is turned on. I tried manually selecting the carrier but fails to connect. What on earth is happening I cant figure this out. Please help.

Mine is doing the exact same thing, and it won't update, I still have android 13...

Go to your carrier and have an esim installed. That might help

I just started having this problem, too. I had to replace my first S22 Ultra (which I preordered) with this same issue. The pre-ordered phone lasted 4 months until all of a sudden, the sim card wasn't working. For a while, the e-sim worked on that phone until it didn't. Then they sent me a refurbished one because there were no new phones at that point. That was July of 2022. Up until a couple of days ago, I had no issues. I haven't even updated my phone yet. I really am at a loss here. A factory reset didn't fix it the first time I got the brand new phone. I refuse to do it again. I had to help my parents upgrade from the S10 to the S25+. That was a **bleep**g nightmare. The transfer of data not only led to their phones getting hot it didn't transfer over half of the stuff. Plus the photos were all mixed up during the transfer and ended up on their Google storage which led to them having to delete photos because they hit the max storage. I refuse to have the same issue.

Negative , New Sim , or ESim does nothing for the S22 ultra connection issues.

Exactly same problem here.

Similar problem for a fold 5 with an esim. Constantly dropping service, and won't work 4G at all. It's getting frustrating.

Same here with s22. 2 months now! Starting to wonder if it's Samsung trying to get people to buy new phones!!

I had similar issue with my s23. Phone was bricked after one ui 7 update. I thought it was due to the one ui update, like a software issue. I flashed the firmware to the newest version. Didn't work. I even reverted it to older versions. Didn't work either... After some research, I found out that it's likely caused by faulty USB charging board. It turns out that this is a quite common issue with s21,22 and 23. Somehow the antenna is relying on the charging board.

I had the USB charging board replaced. And it worked! Repair kits are available for 15 bucks online. It took me 30 min to replace it. Or you can have someone do it for like $100.

Same issue. All paths seemingly pointing to a known antenna / flex cable manufacturing defect. But my issue started almost exactly the same time as the OP which is very strange indeed...
