For me Airtel is the best network from all I have used yet. I have been into airtel network for about 4-5 years and I’ve never felt a need to switch to some othwr network even for once. The network signal reaches everywhere even in the basements and places where it is difficult to catch network for other operators. The call rates are not so pricey. The internet servuce is great as well with affordable charges. The new 4G ntework introduced to this network is actually really fast and amazing.
