I regret I should have checked reviews before, this device is pile of sheet. Dont waste your money in buying it, better go for any wired broadband. I am paying ~900 PM and always had a trouble, during normal human hours(not talking about midnight!) this device hardly gives 15KBps, some time even simple ping doesnt work.
If I report a problem then tata executive visits my place 2-3 time and then no improvement, lately they installed antenna at my place but still it sucks, same speed, now I m going to burry it down and buy new wired broadband. Actually this guys are tricking people, speed they bost and advertise on TV is approximately true when only few users connected to their base station, but that cant be a case in india, so its never going to work. Also when they give a demo, or want to close a ticket some how they trick the speed of you device and from next day its same again!
