I've been going round-and-round with prepaid "support" on this and am at the end of my rope.
Here's the situation:
1) I activated a pre-paid line, with a Verizon provided number, with a Pixel 3XL. I tested the network speeds and coverage with that number including calls/texts/RCS
2) After I was satisfied I ported in my number from T-Mobile. Still using the same SIM in the same phone.
3) Calling/Texting work just fine. However the 3 people I know that can get RCS from me, still get it from the number I originally had, rather than the correct ported number.
Here's what I've tried:
A) Deleted all messaging threads with these folks from my phone and had them do the same on their phones. No Change.
Cleared the data for the messaging App on my phone. No change.
C) Turned off RCS (Chat) on my phone, sent them some messages via regular SMS (those arrive from the right number), then turned Chat back on, and again, back to the wrong number.
D) Once again deleted all threads with these folks and then the data for the messaging app and had one friend do the same on their phone. New chat still comes in from the wrong number.
E) Factory reset my phone. No change.
F) Spent over an hour on multiple calls with multiple reps who didn't even know what RCS was, but still claimed they had fixed the issue, but of course, no change.
I know the Pixel uses Google's Jibe hub, rather than Verizon infrastructure, so the question becomes how do I find someone at Verizon that can fix this?
