Its good because it will give you free net for 3 months which is great. And coming about speed it is fast enough to load pages and watch online high streaming videos. I had personally used it and I dont have any queries with it except for one thing that is it doesnt give the best calling facilities. But for that I am using data to call my friends.
I am presently at Andhra Pradesh and here the network coverage area is good. It is free for now but after December 31st its going to charge. The data charges are not high i.e 50 ruppes per 1 GB per month. So overall it is good enough to have it.
And another thing . I read in some magazine that they will give you free net and calling upto the month of March.
Another thing is about the customer service which is the worst customer service that we have on any other network.
