Wrong number on account

[Gb2025]

I changed my number and registered my new SIM card. But my old number is still registered on my account. When I log in, they ask me to activate my sim card. They tell it's already done. It is because I've been using it for months now. What do I do to fix this

what do you mean you changed number ? If you just wanted to change your PM number, you didn't need a new sim. You just download the app to your cell, log in and go to the Account tab...tap it and scroll down to see Change Phone Number.
