Aircel a chennai based mobile network, they have the best offers and low priced service packs . Best talktime rates, best sms packs, best internet packs and nice value added services. Better than any other mobile networks.
But, network coverage is very bad, range is low in most of the places, they have worst customer care services and also very bad data speed. Network speed is really low. They need a lot of improvement. If they improve their coverage then, no one can beat them.
