I have been using airtel since 3 years, earlier I used to though that airtel is the best company as their network coverage were excellent, but after some period of time I notice that that charges and billing amount rose very high. Even the 2G package was so high that it was not possible to afford as a student for me. Though airtel speed is quite good it’s prices are very high.
Otherwise the network coverage is very very good . I had never faced problem for network even in village.
