Although I was against Airtel's FUP, what I've seen in countries I've stayed outside of India are ridiculously high caps (which one might not even hit), and reasonably priced broadband, in terms with the cost of living of those states.
50-100 GB caps are common abroad, aren't they?
So that doesn't makes the broadband providing companies abroad a Holy Cow ! Almost in every part of the world broadband is considered as a highly milking sector, isn't it ?
