Wanted to get mobile internet, but saw that Airtel was the only ISP offering 4g in Delhi and also its prices were same as 3g.So bought Airtel 4g Sim which got activated in that day itself.
ISP performance has been good, although 4g is still not available in some areas but its available in my home.Speeds are mindblowing, about 40mbps in Speedtest.net.
Airtel 3g also has good speed though, 4g has unimaginable speeds.But they deduct balance for unknown reasons randomly which is weird.They themselves have no idea as to why the balance is being deducted.I avoid Airtel for calling, though internet is good, suggest all do the same.
