Existing BSNL EVDO users can now breathe a sigh of relief, as BSNL has officially confirmed the withheld in changes to the unlimited tariff for its existing customers. It’s good to see that BSNL has reacted for the queries, petitions and requests which were raised by some of their customers. We must be thankful for those who made an effort in contacting BSNL for this very own sake.
Quoting from the official site:
* Existing EVDO customers would continue to avail the unlimited data usage@Rs 650 per month
This means, all existing users can continue enjoying unlimited internet at Rs. 650 per month. However the asterisk sign in the very beginning of that sentence also says that it might be for a time being. And they might increase the unlimited tariff for existing customers as well.
To conclude, it will be good for both BSNL and as well as its existing customers as far the price for unlimited tariff remains the same. If they still have future ideas of hiking for their valuable existing customers, they will definitely lose some of their customers in very short period of time.
I would like to thank ashish_evdo for updating us with the news and dark_king for bringing this into my concern via his BSNL-EVDO-CLUB SMS Channel.
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 
I think if they reduce the price to 400-500 unlimited then this will be better.
