I’m using aircel from past 4 years and there is no doubt that it has the cheapest calling plans. But its has some problems.
Like it has a network problem and the call gets cut automatically. Some times its doesnt connect call.
Network signal gets disappears.
The internet speed is very slow. When you call someone its says person is not reachable and when you call from another operator you can make the call.
The customer care service is very bad and you barely able to ask the customer care.
