I don't know why this is happening, but I'd really like it to stop. It turns the thread into an MMS thread causing subsequent replies to always be sent via MMS, not SMS.
Details:
I have two phones, a Samsung Galaxy Nexus on Verizon Wireless and a LG Nexus 5 on T-Mobile. The Nexus 5 phone number was recently (a couple months ago) ported from VZW to T-Mobile.
This only seems to happen with the one number on Verizon, not all messages sent from Verizon.
When the Galaxy Nexus on Verizon sends a text message to the Nexus 5, it appears to have come from <number>@vtext.com.
In an attempt to solve the problem I have:
1. deleted the thread associated with the Galaxy Nexus on the Nexus 5
2. deleted the contact associated with the number of the Galaxy Nexus on the Nexus 5
3. Cleared the cache for Messaging, Hangouts and People applications
4. Rebooted Nexus 5
5. Sent a text message from Nexus 5 to Galaxy Nexus
at this point, the thread appears to be an SMS thread with the top showing <number> (not <number>@vtext.com).
If I hit "back" to go to the list of threads and then select the thread, now it shows the thread as being from <number>@vtext.com and not <number>.
This leads me to believe there is something associated with this number cached somewhere on the Nexus 5, or alternatively, something is being sent back from Verizon with the acknowledgement of the SMS that says @vtext.com.
This is super frustrating as it switches the entire thread to an MMS thread (not SMS). Any suggestions as to how to make this stop?
Is there something in verizon's provisioning system that still thinks this is a Verizon phone?
Is there some other hidden data in Android associating this phone number with @vtext.com? How can I clear it?
Thank you.
