Yes of course.
Whether you buy the card or take it on rental, you may have to pay activation charges of Rs.500.
But ........... be aware. If you buy the card and then find that the service in your area is not satisfactory,while you may be granted a service disconnection on request, BSNL will not take back the card.
So buy it only if you are damn sure that service in your area is satisfactory. (It all depends on whether your nearest BSNL base stations (towers) are EVDO-enabled and the distance to you)
If you are not sure, I would recommend taking it on rental, so that you may return it after three months, in case the service in your area is not satisfactory.
If you are satisfied you can buy it after one, two or three months as you may choose and thereafter no rental will be charged.(Please read through all the posts where all these have been brought out)
