Definition of Prepaid connection

Prepaid stands for prepayment, is a mobile connection for which you pay upfront for the services like calling, messaging, data usage and any other services, etc. In this plan, the customer purchases the credit before using the services.

The SIM requires that you first recharge for availing a particular service and then you can use it till the amount in your credit is nil or the term for which the recharge is done is expired (whichever is earlier). As soon as the available credit limit is over, you cannot use the services anymore. You need to top up again for availing services. Although there is some payment mechanism available today through which the customers can easily recharge credit at any time.

Definition of Postpaid connection

Postpaid refers to payment after use, is a SIM card in which you can make subsequent payment for the service usage. As per mobile connection, the customer can use the services of the mobile network and then he is charged at the end of the month or the billing cycle, either as per their contract with the service provider or for all the services availed by them during the month.

Normally, the customer is charged as per his contract with the service provider, which specifies the limit for browsing, texting, calling minutes. If the usage is less than or equal to the limit specified, the user is charged at a flat rate. Any usage over and above is subject to extra charges. It can also be said that the user can enjoy unlimited credit.

The credit history of the customer is very important in postpaid connection as it forms a base on which the service provider can rely upon, that whether the customer is capable of paying the outstanding bill amount or not. The contractual agreement specifies that the service provider can take legal action against the customer for non-payment of the bill.
