Can't Access Online Account
I bought a SIM card today at ATT for an ATT mobile hotspot. I tried to access my account online. I entered my "phone number" for the SIM card. (In quotes because it does not allow making phone calls.) And my ZIP code.
But then it wanted my billing account number. How would I have any access to that if I can't get into my account? How do I get into my account, please?
