I purchased a Tata photon plus connection for my laptop. But it turned out to be a big mistake. The connectivity is very poor in Chennai city itself. You have to sit outside your house or very close to a window to get connected. You never know when it will get disconnected.
Even if gets connected, the speed fluctuates a lot. Outside Chennai (say 20-30 kms from city), it simply stops working most of the time. It might work if you sit on the road and based on your luck.
I have tried hard for 3 months to use this but there is nothing which can be done. I did contact support and they were helpful but what can they do when there is basically a problem with this product.
