BSNL Launched EVDO services back in September 2007 and have been upgrading their networks since then. What is this EVDO ?
EVDO is short form of Evolution Data Optimized. According to Wikipedia:
Evolution-Data Optimized or Evolution-Data only, abbreviated as EV-DO or EVDO and often EV, is a telecommunications standard for the wireless transmission of data through radio signals, typically for broadband Internet access. It uses multiplexing techniques including code division multiple access (CDMA) as well as time division multiple access (TDMA) to maximize both individual user’s throughput and the overall system throughput. It is standardized by 3rd Generation Partnership Project 2 (3GPP2) as part of the CDMA2000 family of standards and has been adopted by many mobile phone service providers around the world – particularly those previously employing CDMA networks. It is also used on the Globalstar satellite phone network.
BSNL offers you two types of services
- BSNL NIC Cards (Speeds up to 144Kbps)
- BSNL EVDO Cards (Speeds up to 2.4Mbps)
As of date BSNL offers roaming facility also on both type of Cards as well.
Cost of Data Cards
The data card is available on both rent and purchase basis from BSNL. In case you purchase the EVDO card of NIC card , it would cost you Rs 3500 and 2500 
respectively, but in case you do not want to purchase it from BSNL then you have option to rent it by giving a refundable security deposit of Rs1000 and monthly rent of Rs 200 for EVDO cards and Rs 150 for NIC cards.

If you plan to purchase a BSNL EVDO Card or a BSNL NIC card please note the following things.
- Speed mentioned is upto 2.4Mbps in EVDO Card , it might not be possible to get full 2.4Mbps all the time.
- Speeds of upto 2.4 Mbps is subject to technical feasibility.
- Not all cities have EVDO enabled towers.
- If you are in an enclosed space then it might not be possible for you to get speeds up to 2.4Mbps.
- The distance between BSNL Towers and your residential area is also an important factor in speeds.

It is realy a bad service provided by BSNL EVDO. When i purchased from DUMDUM,Kolkata BSNL office, the officer told that it is not posible to get 2.4 Mbps under any situation except one BSNL tower is used by only one subscriber. Is it realy possible to use one tower by one usera at a time?It is impractical. When i said this to the officer he told me though ur home is just beside the BSNL twoer …you will not get not more tahn 400kbps. But the fact is more sad that his promise. Now I am getting 150 Kbps instead of 2.4Mbps(whet they are always giving in add).I have reported the fact to BSNL …but they are saing u will not get more than than in practice.
Now you people decide whether you want to waste your money or not.

Dear.
I want to purchase evdo card in Jammu. I would like to know how and where to go to have the same. Whether BSNL has appointed some franchies or BSNL office itself is providing the same.
