Registering Account Online/Lost account number

Thanks for reply.....

However when requesting temporary password...apparently they just send to phone...and not to "email on file". Remember verifying my email when purchase made...guess will have to have the phone in my possession before i can register....No email received.....

Called support advised they do not send temporary passwords to emails...only text....Will have have phone in my possession to register account.

A temporary password will be sent in a text and to the email on file (on file for at least 30 days).

Re read my post... 

Purchased a phone at Wal Mart, then went to an AT & T store to activate phone. Paid an activation fee plus one year of prepaid service.

Again, you DO NOT REGISTER A PREPAID ACCOUNT.  The process of creating online access is for postpaid users who will use the Myatt application.

Your prepaid account was created for you on the pay go online website. You log in with your 10-digit phone number

100% yes. 

Everything involved with your prepaid account will go through your phone as a text message, or a phone call.

Your email for verification and notification purposes only.  

I am a little puzzled why you opened an account and paid for a full Year's worth of service but don't have the phone.  🤔

Correct. 

Will have have phone in my possession to register account.

No.  🤦🏼‍♀️🤦🏼‍♀️🤦🏼‍♀️🤦🏼‍♀️

Your pay go online account has already been created for you during the process of activating your phone on the $300 plan.  

Done.  

You cannot create an access ID for postpaid when you have signed up for prepaid service.  

Phone was gift...nothing nefarious

Wasn't suggesting it was anything nefarious. If you've given someone else the phone and paid for a year of service, they're the only one who can access the online account.  The phone is required every single time.  

And if you've paid for a year of service ($300 plan lasts 30 x 12) literally nothing needs to be done for 360 days.  Set a reminder in your calendar. 

In fact you might want to let the person who has the phone know that if he goes fishing around in the pay go online website and changes the plan by accident the rest of the $300 one year plan is gone.
