I am using an Idea network connection since some years. the signals are always maximum. some times in metro or basements I have faced a little problem while calling.But the plans of calling, messages, data card are good and cheap compared to other operaters. they regulates the offers and schemes in every phase of time and bring great offers especially for post paid users. now here also, idea 3G internet is also available, I have used it and seriously it have a very high speed and the plan is also not in very high rate. All in all it is good mobile operator.
