Has anyone tried doing a factory reset and not doing the update?

Yes, and it did not help at all.

Wait, really?

So my Samsung Galaxy z-fold 3 was sent to Samsung due to an entirely different reason, I used one of the Spigen tough armor cases on my z-fold 3 and was stupid enough to let the adhesive stick to the millimeter wave 5G cover that is above the volume rocker buttons and when I took the case off to clean the device it completely pulled the millimeter wave cover off. I sent the phone to Samsung and they contacted me and let me know that they fixed the millimeter wave cover but also fix the LTE issue the phone was having so I wonder what else is really going on with the default 3 in t-mobile?

Just did the *#2263# fix and it resolved the data issue. Thanks for all the help guys!

This is what I found on the Samsung forum. So far it seems to have corrected the issue for now. But we will see if it reverts back to in and out service or not.

I wanna say this has helped me and now I can send messages and make calls and other things without connecting to home wifi. Follow those steps theh work.

^^ This - after spending time on the phone with support who "Never heard of this issue" I located this and tested, my phone has been stable for 48 hours vs going offline every 30 minutes. Even worse is that I did some traveling from Seattle (T-Mobiles home) to Portland and this expensive phone was nothing more than a timepiece the entire trip. Yet my S21 Ultra had a connection the entire time.

So I had great luck with this action, and would tell T-Mobile but they are now 24 hours past when they promised to call back to see if the general settings\network reset worked (hint, it did not). 

I have the unlocked version directly from Samsung and I'm using it with the TMo Sim card. After doing all the dialer code settings, going to Tmo and finding everything Whitesalt mentioned to be true, etc. I finally just took it to Samsung's authorized service center, Best Buy Geek Squad, which Samsung said I could do. They had it for 2 hours and restored the software to the original Android 11 3.1.1 Now the phone works again without me having to do the dialer *#2263# 

So for me this connectivity problem turned out to a software issue so far.

Well guys I sent mines to Samsung and as previously stated they changed the pba. Upon receipt, I downloaded android 12 and have no more issues. Hope this helps because I love the phone as many of you do!

I've tried this "#2263# thing several times but mine phone always says unable to process this request. How do I get the code to run thru? Any suggestions?
