Idea is one of the oldest network along with Airtel. Network coverage is also good in rural and urban areas. They don’t offer best goodies. The tariff rates are higher than other. It offers good 3G pack but connectivity to 3G is very weak, it gets disconnected.
It only sometime provides very good offers. Last week, I got 1 GB 3G Internet with a top-up of only Rs. 97 with validity of 28 Days. I was really a good offer.
