Airtel is offering 4G services in NCR but my experience even with 3G has been pathetic so-far. I am living is Gurgaon that is a cyber city and should be having seamless connectivity but the problem is 4G is very far even I don’t get 3G signals any many places like sadar bazar area and most of the time my iPhone is getting EDGE connectivity only. I wont recommend people to think of 4G when even 3G is not available most of the time.
They are charging 2 paisa per second on prepaid and 3-4 times a day my calls get dropped in-between conversation.
