I can buy a dongle for INR 400/month, isnt that cheaper?

    A dongle connection might be cheaper if you are using it for an individual, but it is not suited for a classroom. The bandwidth of a single dongle wouldn’t be sufficient for more than 2 students. This means would you need at least 10 dongles to service a class of 20 students, which would cost around INR 60000 per year for data and additional cost of dongles and other firewall software which in total is more than INR 60000, making it more expensive than Class cloud which costs INR 45000 annually and INR 35000 as a one time cost for the device.
