I live in Ghaziabad and in my area airtel network never works fine on some days it works good and on some days it becomes even impossible to talk on phone due to bad networks.I am using airtel sim since last 1 year, but internet connection was very bad, I am not able to use 3 G well on my phone then what to think of airtel 4G.
Although I have a 4G sim and 4G compatible phone then too I am reluctant to use any 4G service, because I barely got proper connection in my area, and for your kind information I dont live in a village or any remote area, I live in a proper city.
I would not recommend airtel 4G specially at this point of time, firstly they must provide their 3 G services and their connectivity better instead of just raving about their 4G, and spending so much on their promotion campaign.
