I have a strange issue. I got a new phone with a new provider (iD mobile) and my phone number changed (let's call this phone number "number B"), I sent PAC to my old provider (Three) to get my number changed back to my initial phone number from before I got a new phone ("number A"). I have messaged two people since my phone number was supposed to change but when I message them they see the number B, and when they message number A - which I was supposed to have again - I don't receive the message. However, I have received messages from my bank and college who only have number A.
I have no idea what's happening, will this fix itself, or is there a different answer?
