Why 'Rental' is suffixed in 'Postpaid'? I couldn't find any 'Rental' term in entire Airtel site. It should be 'Postpaid price' or 'Postpaid Tariff', rental is a totally different thing.
this is Airtel Black plan with DTH, Xstream. They are talking about postpaid plans as you pay charges at every month are also called as Rental in other's countries. I have postpaid still at old price but it look likes Airtel updating plans in testing phase after updating airtel thanks app. Check weekly after every update
i'm also telling you about Airtel India, coz i also have postpaid plan, but like your screenshot it's did'n't showing in my thanks app, but in my neighbour airtel thanks app showing plan with airtel xtreams just similar as your plan.
