I been through the same thing with tmobile when I had gotten my s20 ultra last March. I had horrible signal, couldn't connect, missed calls and messages and had been on the phone with support over and over for months until I just switched my phone to LTE. They kept saying it was a Samsung issue, I called Samsung and they said it was a carrier issue. So I just gave up on 5G. Then in summer Tmobile announced that their old SIM cards were causing issues with the 5G phones on their network and to get the new SIM card to access their 5G network. Like I said, when I got the new SIM card I had no more connection issues. Like I said, it wasn't a Samsung issue, it was a carrier issue. The phone was trying to connect to a 5G signal and the SIM card couldn't handle that and was causing the signal to get "stuck"...no receiving 5G or LTE signal unless you shut off mobile data by going into airplane mode or restarting your phone. Doing that would free up the SIM card but then you would keep having same issue once the phone finds even a faint 5G signal somewhere and the SIM card would get stuck again.

 

US cellular is a little behind the major carriers as far as 5G adoptation and so they probably don't even know what's causing the issue yet. Eventually they will upgrade their SIM card as well, but since they are a CDMA network, you should change your network to LTE/CDMA and restart your phone. I understand your frustration, I went through it for about a month before I switched my s20 Ultra to LTE before tmobile released their new sim cards.

Have you tried resetting the network settings? Just a heads up, by resetting the network settings, it will remove all wi-fi and Bluetooth settings you currently have saved. Have you tried another SIM card in your device? Do you experience these symptoms if you test your device in safe mode? Based on the symptoms you are experiencing, this appears to be an issue with your carrier, I would recommend reaching out to them for further assistance.

Yes we have tried reset network, yes we have tried new sim, yes we have tried factory reset, yes we have tried firmware updates.

 

No they have not resolved these issues. They are occuring all over the place. It's not carrier specific!!!

 

LOOK!!!!

Are you seriously saying ALL these people across the globe with multiple different carriers are having carrier issues. Samsung need to sort this problem out. A flagship phone that doesn't work reliably as a phone is unacceptable. 

 

Why will Samsung not acknowledge there is a problem here. There clearly is.

 

Maybe we should all just take it to the media and create a PR disaster for samsung since they don't seem to give a toss about their customers.

 

This will be the last Samsung handset I ever buy. I'm done with Samsung.
