chris moyles xfm - does listening on the app use phone data?

[QOD]

Whatever anone else thinks of him, I loved moyles and the gang
however in kent, can't seem to tune in to 104.9
I've downloaded the app to my phone but surely it'll eat my data?

Buuuuuuump

if not on wifi it will use mobile data

boooo hiiiissss

Thanks
