Postpaid is a telecom service plan where you are billed a predetermined amount at the end of the month of usage. The month is called the billing cycle and may not refer to a calendar month.

The main difference between prepaid and postpaid is that for the prepaid connection you recharge before the usage of the telecom services and in the postpaid connection you pay after the usage.

Which is the best plan for me?

The answer to this depends upon the usage that you have. All Airtel Postpaid plans have unlimited calling, daily SMS and a bundle of data (that can be carried forward to next month up to 200GB if not used) You can choose the one that fits your needs. Check out the available plans here:
