I have been using my Idea number since 5 years. It was good from starting to still. Its network coverages is issueable because its tower is less then airtel or other network operator. some times its network is fluctated in my area . I am using it within 70 km radius per day, in which I found its network thatmeans signal strength is not strong at every place. The call drop is also a problem. Initial time company was given the best offers but now it is not economic in using. The data price is also high in comparison of its service. Although I am using it because my this number is given to all my relatives, friends and my employers.
