For using it you need to activate OD & wifi topup on your account but the topup codes are not available as Adtv has stopped that service from few months/years.
You can try activating it by using OD & Wifi as topup codes. See if it gets activated.
I told nodal officer about it in Nov 2018 & he said that they'll relaunch it very soon with more content but no update till now.
