Idea , one of the largest Indian network . It's customer service is fast and it provides best quality in calling and net surfing. No doubt Idea has best quality and people have thier best experience with Idea.
The most important thing which makes Idea best than others is it's signal quality and availablity of signals in evry corner of country also in far villages and rural areas.
But it's high pricing is it's big negative thing. And there is also one more negative thing is Idea is also far from providing high speed 3g internet in rural areas and villages of India.
I hope we will see Idea as best service provider in both areas cities and villages with affordable prices.
