Airtel is India’s biggest and fastest network with a wide coverage area but while comparing to other networks it’s Tarrif Plans and other services are costly. An another problem is coverage in rural areas. In some villages in Bihar it’s service area is limited and there is also not any service of Airtel 3G but overall this network is biggest and fastest growing in rural areas. In our area Idea is a big competitor of Airtel because Idea has good Tarrif Plans and Customer service.
