This is the best data card i have used.....ie., EVDO

Access speed of 2mbps and
Download speed of minimum 150kbps....

and just Rs.550 per month ....if u have purchased the EVDO device for Rs.3800
if not Rs.750 per month (Rs.550 access charge + Rs.200 for rent of devise) ....Rs.1000 - security deposit (Refundible)

You will come across 2 types of cards..
one is EVDO which i have said above...
another is NIC card...

Nic card is of very low speed

its details are as follows

Access speed of 230kbps
download speed of 25-30kbps
Rs.250 per month if u have purchased the EVDO device for Rs.2500
if not Rs.400 per month (Rs.250 access charge + Rs.150 for rent of devise) ....Rs.1000 - security deposit (Refundible)

in these two types of cards i suggest Evdo data card is best....

i have tried NIC card also....but not satisfied with speed

Purchase Price (INR):

Ra.3800
