Pay My Bill
From PhonePower Knowledge Base
When you log into your MyAccount portal, on the Account Home page is a section titled Service Account Details. In this section it will list your Account Number, your Current Balance and have a button that will allow you to pay your bill labeled Pay Now.
When you click on the Pay Now button it will take you to a page that will allow you to pay the entire current balance, or to pay a part of it. Once you have decided how much of your current balance to pay now, click the Pay Now button.
