I have been using airtel for calling and data on my mobile since past 4 years and to be honest I have had nothing to complain about. It’s network is the best compared to others. Never have I faced an issue like no network or call drop. It has happened many times that I and my friends have gone out to distant places and everyone’s network was gone at some time or other except mine. I have really loved airtel for it’s strong network coverage. I was only pissed off by the high tariffs it used to charge for mobile data, but since the entry of jio in the market, the prices have come down to satisfactory levels for me. I have been benefitted more than the jio users. Pun intended. To conclude, airtel is and will always be the best
