i had bought tata docomo estick hsupa on 29th oct 2011.n activated a postpaid unlimited plan of 10 gb data access
n within 6 days of me buyingthe product it showed connectivity issues n errors in network connection.for 2 days from then it stopped functioning disrupting my important work schedule.
after a visit from the techincian based on his report i had to get the sim replaced paying an extra cost and now after the replacement a product promising 3,6mb/ps speed is working at speeds of bulls.....all these products coming with high promises are crap and fake
