By the network the airtel is gone popular because it has a fine network as well as in rural area also it gives very good netwok even where other companys network failed the network of airtel gives superior network.
im living in side of village area and the airtel network works better and if we talk about its customer support its always be with the customer and gives satisfaction. by the time the mount of customers are going high for this service provider.
but if we are talking about its tarrifs and bills than some other companys service and tarrifs and bills airtel is
costlier so this is the bad point for airtel.
but one base no one can go high so the company needs to some changes in his these kind of job
