Airtel 649 Plan

Is Airtel 2 MBPS Rs. 649 plan unlimited? or they will charge after 3 GB of data usage?

i think you pay 20 paisa per MB till your bill amount reaches 2000. after that you get 256kbps.

It means I will pay 20 paise/MB after 3 GB and my speed will also be reduced to 256kbps after my total bill amount reaches 1999.

check the plan details. airtel has too many plans and your plan might be different from the plan i had to live with for a month. the plan i had offered 3GB at 2mbps. after 3GB i continued to get 2mbps but i was paying per MB of usage. this usage had a limit of 2000 bucks after which speeds were to be reduced to 256kbps.
