I am using airtel network since 5-6 years , it has a wide network range in india includes huge range of villages & small towns , I bought it for a good network at any place of india, I am mostly working in field so it helps me a lot , now it gives me best offers for calling & internet also , 2G nework is so good but 4G is not availible at some villages as jio avils , but I am happy with my airtel,
