Doctor sahab, I couldnt understand this - "The firms seem to guarding EVDO pricing and service rates like mama bear. "
Yes, these are the three major players. But BSNL service, in my opinion is not as fast as Reliance at least in some areas. The good thing is that you hv truly unlimited service for Rs. 650 (which the other boarders claim to be Rs. 999). The bad part is that the speed variation is huge. If you are lucky and live in an area where the speed is good, you get speed of around 600/700 kbps. But there are people who get speed of 30/40 kpbs too.
Besides, if BSNL has really increased the monthly rental, then it has lost its advantage because at the price point of 999, Reliance would be far better.
