Lost capability to text: Contacts show sip:[phone number]@msg.pc.tmobile.com;user=phone

I have this issue as well.  In case it helps, I've noticed something that might help T-mobile better understand the issue and might help us all find a workaround.

I've found 2 contacts so far that have this problem.  Both of them are on my same family plan.  Although others on my family plan still work as expected, so it's seemingly hit-or-miss as to whether this problem occurs.

For the two contacts that have the problem, If I create a new chat and type in their name, it doesn't work as others have mentioned.  However, I am able to still text them if I do this:

• Open the contact in my contacts app
• Click the message icon to message them
• This opens up the messaging app on the historic thread I’ve had with the (functioning) contact.
• Texting out from this works.

However, once i text out using this method.  The texts *back* show up in the sip: named thread instead of my historic thread.

So, it’s not a great workaround, but if you really have to get a hold of someone, you can do it this way.

Tmobile… we'd very much like a fix for this.  ¡Gracias!

BTW, I’m using a Samsung S22 phone, on Android version 13.
