BSNL is the first to roll out EVDO Internet in India. The EVDO was launched unofficially back in September 2007 by BSNL and now, after the establishing better EVDO network, BSNL has started to launch officially in most parts of the country. Since it is a very new service, the official information is very little. So we decided to set up a unofficial portal with user-based information and more. So we hope this site helps you to get information regarding BSNL's New EVDO service. Keep visiting the site and dont forget to register in the
