Tata Indicom Plug 2 Surf is very good product to use compare to the other because compare to other products available in the market the Top-Up values is not so costly. I am using this product since 2 year back. I am enjoying this modem when we recharge with 201 we get 512Mb downloading free for one month and 10Rs balance which is enough for the people only wanted to surf the data. The only one Cons of this product is that some time the speed is very less but this not happens all time.
So my suggestion is to all of you buy this Tata Indicom Plug 2 Surf.
