It depends on what type of plan you have with Verizon. You have to check with them and make sure first.
Hey there Constance, I'm not familiar with that particular app but typically with audiobooks and movies/tv shows you have the option to download them so you can use them offline. So if you can download them using wifi and then listen to the copies that are downloaded on your phone you won't use data. However, if you are streaming the audiobooks you would be using mobile data. Hope that helped! -Derek
