What is a Prepaid Connection?

If you have a prepaid sim, you will have to first buy a prepaid pack to use mobile services like calling, data, SMS, etc. Every prepaid plan comes with a validity period ranging anywhere between a few hours to a year, depending on the services you are availing and the plans available. Once this validity period expires, the plan’s respective services, which can be calling minutes, data or SMS services, stop working until you recharge again with another plan. That's why in prepaid plans it is important to keep a track of the validity date to ensure uninterrupted use of mobile services.

What is a Postpaid Connection?

In case of a postpaid sim, you use the services first and then pay a consolidated bill based on the services utilised at the end of the billing cycle. It is just like how it is with your utility bills, you first use the service and as per your usage a bill generated at the end of the month, which you have to pay by its due date.

Many telecom operators also offer postpaid family plans, allowing you to add multiple family members under a single plan
