Postpaid is the opposite of prepaid, and is simply a matter of the billing structure. It has implications on the nature of the relationship with the carrier. Postpaid contracts tend to offer a large variety of services and options. The bill is a direct result of the usage during that billing period, including fees/costs for excessive usage. Prepaid contracts tend to offer a minimal amount of services that are paid up-front. If customer usage exceeds what they paid for, the service is cut off. The carrier has no duty to provide service beyond what the contract states, and indeed the point is to remove that liability from the customer as well.
