I would be very interested in knowing this too. Has anyone tried using Speed on Demand? Especially those who are on the Home999 256kbps UL plan (and still getting double speeds at night).Bandwidth on Demand = Speed on Demand, right?add:I am getting that error even just trying to get to that page to login to the service (airtel.in/bod). I can't even reach the login page, forget selecting speeds.... Some service...
