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

Hello,

 

I used to text this mobile phone for several months.  I am using a Samsung Galaxy S21.  However, today, the text fails to be sent.  Then, I look at my contacts for the mobile phone number and it is changed to:

sip:[phone number]@msg.pc.tmobile.com;user=phone

 

I removed this and updated the contacts with the correct phone number, but the text does not go through and the contacts is changed back to sip:[phone number]@msg.pc.tmobile.com;user=phone

 

Any idea what is going on?  I am able to text other people.

 

Thanks,

 

Paul

I am having exact same issue with just one contact.

We were just in t .obile store. I can send message to that number now using my existing contact. But, receive replies on the "sip" contact. The language in the "sip" contact makes it seemlike messages going through a PC.

Bump. Also having this issue with exactly ONE contact. This person uses Metro PCS. Just started within the last week or two.

They did nothing. They were at a loss. It is not fixed.

Following. I lost the ability to text my son although he can text me and I have no problem texting anyone else. I get the same "phone number" in my contacts. T-mobile showed my how to test network connections and it worked for 3 messages then failed again. Let me know if anyone else has any ideas.

I don’t know what’s going on but I can tell you that the SIP address looks like a long-ago backdoor to allow people to call T-Mobile phones from PCs and other Internet devices. It was closed down due to security concerns. I only found out about it a couple of weeks ago.

I don't speak for T-Mobile.

I saw PC in there and thought same....but messages that do go through are her phone to mine. It's very weird.

I am having the same issue. It’s one contact, my husband. The people at the T-Mobile store had no idea what was going on. So no solution. I tried to delete and redo the contact, nothing helped. Oddly about 5 months ago my husband was having a problem texting me. It ended up resolving itself.

T

I have the same problem and it only one contact, my fiance. What is the solution? 

J

Same. It’s my mom. Anyone have an answer yet?

S

I'm having same problem.  It's with 1 contact.  Tmobile can't help? No solution?

M

Had the same issue with sip and only affecting 1 contact.  We did the system  update to Android 13 and she texted me and I responded and it worked.

It was the update that did this when updated a week ago. Do they have new update that fixes it? I have s22. 

C

I'm having the same issue. Why isnt this resolved yet?

M

Had the same issue with sip and only affecting 1 contact.  We did the system  update to Android 13 and the sip went away.  Thought all was good when she texted me I was able to text back but then then a few minutes later I cant get texts to go through to her again.. ERG!!

I'm having the exact same problem with a couple of my contacts. Happened after the latest update. T-Mobile please fix your mistake!

J

I just started having this same issue with my Mom. This is clearly a common problem. Where is the fix T-Mobile?

A

I'm having the same problem with a new contact. She can text me, but I can not text her. Weird. Please fix
