Make a one-time payment or set up automatic payments with Autopay. You can pay by credit card or bank account. Not only is paying online convenient, but it also gets you an immediate record of your payment.
In addition to making payments online, you can also view your bill online (including past invoices) rather than receive a paper copy. You can change your bill-delivery method. You can set up alerts in Control Center so you'll always be aware of billing-related activities to your account(s).
