Hi MS..
I had taken the BSNL DataOne connection last month and I am pretty happy with it.. I have not received my first bill yet ;-)
The connection is fast.. As promised, downloads (with Opera or Flashget) give anything between 26-30kBps. I usually get 28-29 for most servers..
Coming to P2P software, BitTorrent gives me 25-28kBps consistently for popular files.
I am using a Rs500 plan, and hence there is a 1GB download limit.
But theres no limit between 2AM and 8AM!! So better go for a download manager which has scheduling options (Flashget, uTorrent etc..).
During the fist few days, I was having severe problems with the connection.. It just wouldnt connect. Now everything is OK.. In the last 25 days, my data transfer stands at 6.7GB. BSNL gave a website https://dataone.in to check the usage statistics. But for some reason, the site doesnt work. After contacting the technical support, they gave another site https://10.240.43.216, which works fine.
Only problem is that the site gives data transfer including the free-time transfers. So its up to the user to take a calculator and subtract to find the actual data for which the bill will be made.
Unlike cable internet, this is a connection based service, meaning you have to create a connection for Windows/Linux and then use the connection. Its easier done than said.. Just create a broadband connection in Windows XP, or a similar PPPoE connection on Linux..
To sum up:
Pros:
Promised speed (< 30kBps)
Good connectivity
Good technical support
Cons:
- Data transfer limit (necessary evil?)
