To explain how you can cancel your Quibi subscription we first must explain what Quibi is.
Quibi is an application where you can watch short videos that can be 10mins long max.
And if your subscription is coming to an end, and you do not want to continue paying, or maybe you want to cancel your free trial without having to pay the fee for the next month, you can easily do that any time you want.
