As I purchased airtel dongle last week the speed is awesome and the signal strength is good and there is some problem with connectivity and this does not work when we go far from the network and the price of recharge is very high as I got it in last week the speed is ok I should check the speed later for now its ok and fine and should check in future use
the performance is ok and I got no problem in these days as it is new as every body says that the isp is not good in service so I need to check so I reccomend ok product to buy for use in home or out side
