Can't log into my sbcglobal email
I have an sbcglobal email account. I know the password and I am logged into it on my old phone, however, I am trying to log into the email on my new phone and my computer and cannot because I do not have an AT&T ID. I have tried to 'manage my account' on my old phone where the email is logged in, but it will not allow me. How do I get an AT&T ID attached to my existing sbcglobal email?
