Advantages of automatic refills for AT&T prepaid phones are that service doesn't get interrupted and the customer doesn't have to remember to pay his bill every month. The customer can choose his payment amount and refill frequency.
The customer can set up automatic refills through his online AT&T account. As long as his payments are successful each month, he doesn't have service interruptions.
AT&T offers multiple prepaid plans that have no annual contract or credit check. It has package plans that combine features, such as talking, text messages and data, and it offers features individually. Each plan is valid for 30 days. If customer renews his plan, any remaining balance rolls over to the next month.
