Airtel Impatience 1799 4Mbps - No FUP?

[Saiyan]

^^ Here in chennai ? :O I thought every plan from Airtel comes with FUP. Although my friend has a 4Mbps till 20/30GB plan and he says that he doesn't get FUP'd. :S

I took this plan just before FUP was introduced. Initially it was 512 day and 1Mbps night, later it became double.
