S25 Ultra will randomly switch to "Emergency calls only" (T-Mobile)

[SpAgent19]

Hello. I have been using the S25U and am pleased with its overall performance. However, I have encountered an issue where the phone sometimes switches to "emergency calls only." After contacting T-Mobile, they were unable to detect any problems. I am curious to know, if anyone else has experienced this issue. Any advice or assistance would be greatly appreciated.

Thats possible, have you tried the sim in a different phone?

No. I'll give it a try.
