Used uniconnect a couple of times, I am really happy with the service they provide, with no hidden costs, 24*7 customer service help, Great network, Charges are as low as calling India at less than 1 rupee.
I was supposed to travel to USA and the quotations I got from many other companies were quite high than what I expected, while Uniconnect offered me much more in just 4200 for a month wid no extra charge .
