View and pay your AT&T bill online by logging into your account through the company's website. If you have not registered your service to have online account access, you can do so through the online portal.
When you visit the online log in portal, there's an option under the log in form that allows you to register your account for online services. Once you have done that, you can log into your account using the User ID and password you created.
The online portal allows customers to view and pay their bills for any AT&T service, whether it is wireless service, phone service or Internet service. If you are a wireless customer, you can view your bill by logging in, where you see your current bill displayed. You can view a PDF version of your paper bill through your online account as well. If you would like to pay your bill, select the Make Payment button located at the right of the amount due, and follow the instructions from there.
You are also able to view your bills by using the AT&T mobile application for your smartphone. You have the option of selecting the bill you would like to pay, including the ability to split the payment to make two separate payment dates.
