I have been using airtel from past 7-8 years and it never let me down. Its 2G is best among all, its 3G is bestest and 4G is above all. Speed is really good as compared to other networks.
Always reliable and every one in my family using Airtel only. Even during journey it always show network. Other networks breaks for hours during journey.
Customer service is best and outstanding.
I never faced issue of balance deduction without any reason like reliance do.
I strongly recommend Airtel to every one.
