Airtel Mobile Network is one of the leading networks in India.In terms of signal quality, its good.Even in areas far from city, the network coverage is good.I am using Airtel Mobile Network from 8 years.At first it was good both for both call rates and data packs, but now both the call rates and data packs are too expensive.3G data packs are also expensive but the downloading speed is good and constant.There is also not a big variety of rate Cutters.The customer care service is good.Overall its a good experince with Airtel but not the best.
