Airtel is one of the best mobile operator in india.when there is a question to buy new sim, most of the people opt Airtel. This is because it has wide range of network.There is common saying of village peoples that they buy Airtel because almost every village has airtel network but not other operators.Nowadays Airtel is giving special offers which most of the operators doesnt give.With recharge of 149 rupees I am getting 4gb data which is very best for me to use.There are lot more offers, All I can say is Airtel is a competator of jio.
