What is the bill cycle of my postpaid mobile bill payment?

In India, postpaid mobile customers generally have a fixed billing cycle as determined by their service provider. The billing cycle length is the time from one billing date to the next, and this is usually a 30-day period. For that 30-day period, all mobile activity, including: voice calls, data usage, SMS, and other services will be accrued and presented on a monthly invoice.

Here is how the billing cycle operates for nearly all postpaid customers in India in 2025:

• Service providers generally assign a start date, and end date for each billing cycle throughout the year. For example, your billing cycle may start on the 5th of the month, and end on the 4th of the following month.
• Every call you make, MB of data you consume, and SMS you send during that defined billing cycle, will all be captured and defined in your months' bill.
• When the billing cycle is complete, the service provider summarises all the activity in the billing cycle period to provide a complete bill informed by your activity.
• The invoice is sent to the postpaid customer shortly after the billing cycle is complete, and it clearly states a date for payment that is due.
• It is imperative to pay your phone bill by the due date or on the due date. If you pay after, there may be a charge for late payment, and late payment can lead to suspension of service.

To check your exact bill cycle dates, login to the account on the service provider website or mobile application. Customer service is also there to assist with bill cycle dates.
