When its comes to mobile network everyone prefer to a stable network with low cost. But airtel never do this. They claim that their network is fastest but its not true. It has a bad record of call drops. Data plans, calling plans are much higher than other operators.
And talking about costomer service its very disappointing. Customer care hardly recieves any call and their behavior is rude. And most of all they hardly solve any problem with customer. airtel is not recommended at all.
