If there already is an Account Owner created on your account, they'll need to approve you before you can get full access to Self Serve. Usually the Account Owner is the person that pays the bill for your phone. Ask them to log in to Self Serve, and approve you using the Role Management link in the My Profile Tab.
If you previously registered for Self Serve, it's possible that you already have an Account Owner profile. Registering a second time will create a new Self Serve account for you, as an Account Manager. In this case, you'll want to log in to Self Serve with your old Account Owner username and password. If you can't remember your old password, use the forgot password link to reset your password and then login to your account. After you confirm a few details, the next time you login to your account, use your email address instead of your username.
If you still can't see your full account after following these steps, or are unsure of who your Account Owner is, please call us and a rep can assist.
