Add-On Connection and Data Carryover One of the unique points for Bharti Airtel postpaid plans is that the subscribers of these plans get to enjoy add-on connections. All the plans above the Rs 499 mark, which include the Rs 749 plan, Rs 999 plan, Rs 1,599 postpaid plan by Airtel come with add-on connection. For the unaware, the add-on connection is something that is billed together with the primary connection. So, for example, you live with your spouse, and you have a plan with one primary and one add-on connection, then both of these numbers will be billed with a single postpaid plan and under a single bill. This will save the subscribers some money, which they would have otherwise spent on a separate connection. It is worth noting that data add-on is a feature for the postpaid plans which Bharti Airtel introduced first and then Vodafone RED plans followed on the same footsteps to bring this feature. Another reason why Bharti Airtel postpaid plans are preferred by the subscribers is because they come with the data carryover feature. So, if the users leave some amount of data unused in their account, then they would be able to use it next month. This is something that is not possible in the prepaid plans. For prepaid plans, the subscribers lose on data if they don’t use it.
