You cant expect all these form a Government organization like BSNL. Airtel still needs promotions, hence they provide attracting offers. BSNL doesn't care if you quit broadband service.

Anyway, they are going to provide some games in future. You can check them under [url=http://dataone.in]Dataone WebMail[/url] under "Dataone account administration". You must login. Anyway, it still shows "Under construction"...
