Airtel network is very good. We can get signal in villages also. Customer service response is also decent. Internet service is also good. I am using this network from a long time. The main draw back comes with the tariffs. Airtel tariffs are very high when compared to other networks.
Full talk time and rate cutting plans are very high. 2g plans and 3g plans are also getting costlier. Promotional offers are very less. Other networks offer various promotional offers once in a while. Good for network and bad for high tariffs.
