Problem activating AT&T prepaid sim

Website indicates that phone is activated but the login page does not let me login and can’t make calls or use internet without Wi-Fi.

Thank you for reaching out @cgarnica7.


We'd be happy to help with your PREPAID activation. 


To confirm, were you able to successfully activate your device as follows?


If currently not able to use the myAT&T app to login, have you tried online?


You should be able to sign in with your 10-digit wireless number and a 6-character password.


At activation, the default password is the last 4-digits of the user's wireless number.


Please let us know how this helps.
