[kkishan]

downloaded Airtel pocket TV for my Lumia 520

First sorry that I might be asking this question in a really wrong place but I suspect that I could get the answers I seek....

So I've downloaded Airtel pocket TV in my Lumia 520 but I m completely clueless about how much data it consumes so I want to know how much data it consumes in standard definition n can we change the view in future, if yes then how much will it consume accordingly.....??
