BSNL EVDO internet SPEED in Kolkata

hi,,as earlier i mentioned that in Kolkata BSNL launched two types of data card.
1. EVDO Data card with speed of 144 kbps avilable in entire Kolkata
2.Another is with speed of 2 mbps only for Saltlake / Rajarhat.

i am using the 1st one. but i can able to connect with only speed of 3o kpps , measued by the calcutta telephone site. Here is the link.
And the download speed is near about average 4.5 to 6.5 kbps (download accelarator). so using internet with this BSNL datacard i only understand it is only good for surfing not good for movie or video downloading. u can only download mp3 songs cause they are in much more small size (4-5 mb). But still it takes near about 25 mins to complete the download..so don't hope for brodband download speed by this wireless internet...its only good for browsing the internet.

Still it rocks.hope BSNL will update its 3G network very soon so that we can get atleast 10 kbps constant download speed in DAP (Download Accelator Plus)..
