It appears that some T-Mobile customers are experiencing an issue with their iPhones’ eSIMs
In the afternoon yesterday, Bloomberg’s Mark Gurman tweeted about an issue affecting some T-Mobile iPhone users. Many of Apple’s core communication services, including iMessage and FaceTime, were suddenly disabled for some eSIM-activated lines.
There is a very nasty iPhone and @TMobile bug where iMessage and FaceTime for a device’s phone number will randomly deactivate and there is no way to reactivate it. The only solution that worked for me is getting a new physical SIM card. An extremely disappointing issue.

Removing the eSIM and re-registering the account on the iPhone is one option for resolving the problem. T-Mobile stores can also activate and install a physical SIM card that can reactivate iMessage and FaceTime.
It has since been revealed that T-Mobile is working with Apple to resolve the problem. Even though this bug has been confirmed to affect iPhone customers on iOS versions 15.4, 15.5, and the current version of iOS 15.6.
T-Mobile reached out to say they are working with Apple on trying to resolve the issue. Sounds early though. T-Mobile saying it is an iCloud/Apple ID-related problem. Hopefully this gets resolved in an iOS update. https://t.co/DuvSpHGP3l
