Hello,
S22 ultra here. After our TMO account was hacked, I keep getting "Sign in to network."
I never had this issue before and suspect it’s on the TMO side of the world. Yes, I have called TMO several times and everyone has been great, they just can’t resolve the problem.
Thanks!
Have you tried changing Sim cards?
No, I will stop by TMO on the way home and do it.
Thanks for the suggestion, I will return with the results.
Chris
New sim card installed, fingers crossed 
As mentioned above, the sim card has been replaced. Unfortunately, the problem still exists.
I have the same issue. Just started 3 days ago. T-Mobile changed by sims card but it was of no help.
Make sure you're not a victim of fraud or scam.
Replace the simm card, keep bugging t mobile. Have them escalate the call to tech specialist. Most of the first line customer reps just read the script.
I was at this for about a month.
Good luck,
Chris
I have never seen “Sign in to network” on my s23 Ultra or any device I have owned and used on T-Mobile. Are you sure your device isn’t compromised? Have you tried factory resetting the device to make sure there isn’t something on there that was/is responsible for your account being hacked?
