what is a pay-as-you-go-phone? Also known as a prepaid phone is a phone that does not require a monthly calling plan. You can buy these phones in almost any store or on the internet.

ATT offers two different types of phone plans. The ATT phone plans include standard and prepaid. The standard type of ATT phone plan is available on all ATT cell phones. For the standard plan, you must buy a phone with a two year contract and make monthly payments. With a standard plan, you can choose unlimited or pay for the number of minutes you want a month. The prepaid ATT phone plan is for the GoPhone. You pay for your minutes, messaging, and web until they run out. This plan is best for people not on their phones too much.
