Register self service issue

Let me flag a rep to help you out.

Hi there, we’re sorry to hear about this. Is this concerning a prepaid or postpaid account? 

I am paying monthly for a calling/ texting/ data plan. My temperary number it gave me works I just want to get on self serve to see if I can possibly change my number

I think it would be considered post paid as I am able to use my temp number but it hasn't charged me for a first month yet

Did you receive an email about your service and an email for being able to register for self-serce yet? 

It keeps sending me a text asking me to register but when I get to the end of the process it gives me the screen from the screenshot 

Did you request a callback using the link and keyword noted in your posted image?  If not, I suggest doing that
