I have bought a mts wireless wifi dongle last month. You can plug it in and create a wifi hotspot at that place . I thougy it will be really portable and I can carry it with me anywhere I want but the problem is that the mts does not provide its network at all places in India. Since I am living in UP West . Therefore, somehow it is working there but when I went on a vacation tin bihar, it stop working .
In my hometown Also, the networks are fluctuating and I have to restart the dongle again and again to get wifi signals properly.
But the plans are on the cheap side but if you are ready to compromise the network on the account of money .then, it might somehow work for you.
Otherwise, I would say a big no to this product!
