Vodafone I think is a good and cheaper service provider in the current scenario. They are providing internet / roaming / calling and other type of facilities to its customers at a very low rate as compared to other companies. Their network is very good even in the remote areas. Their customer services attitude is quite OK. Their charges as I said earlier is very competitive as compared to others and their billing is quite normal. But I have to suggest that they should improve their network because sometimes a problem is occurred in their network.
