Aircel is worst its call rates are good no doubt but the service provided by it is not sufficient its network is not proper I have complained many time but no response nor he replies properly on customer care it is weak in providing internet service. Dont run behind a cheap network. its services are also cheaped.
I have dual sim phone and using both Aircel & Vodaphone. But if have to choose one between the two, then Vodafone will definitely my first choice. Although, Aircel has cheap talktime & data plans but the internet connectivity is not good.
