I own an airtel sim from last five years now and I am continuously using it because itd the best of all. The network coverage is very good. I live in the hilly area of Jammu and Kashmir where all the other operators fail to provide quality service, it’s only the airtel that hits the bulls eye. Whenever I travel to far -flung areas it’s only the airtel that accompanies me there. Where ever I go, I get the best coverage. The net speed is also very good. 3g and 4g services are very best to other competitors. The only field where airtel lacks is high service charges and costly data packs. For example for one month 2g data pack you have to spend Rs. 245.while in other networks it’s only up to Rs 150-180.customer care services of airtel are best of all. One have not to wait and stand in a long quiew to get their problems solved. Overall the airtel network is best of all of your network companions
