In this time where telecom companies are in a huge competition with there tariff plans or other services airtel top them all wheather be it network or schemes of call or any thing I found airtel the best in india. Coming to network I was traveling to delhi from mumbai on train hardly I found the network bar has totally week its as strong that u can call any one while being in train.
Then coming to 2g/3g/4g speed here also it will top amongs all service provider. Comparitively I found airtel best then any other network in india.
