Network is too good compare to other all networks in india.
But the problem wite the airtel is they cut the money without any reason if you call the customer care they says something u subscribed to callertune services are some other reason even though if u not subscribed this one is the problem with airtel. The service they provide is good and the call rates also good but the free messages are not they give compared to other networks.they give good service and they take good money from one point it is costly compared to other services.
