This is probably a real newbie question - sorry! I recently got an Epic and am slowly, cautiously adding a few apps since I don't really understand the ramifications of the various permissions yet. I am interested in the SiriusXM app, but don't understand why one permission would be "directly call phone numbers". Can anyone explain a) why it would need to do that and b) if it's a problem in with this particular app? I'm on a family plan and don't want to abuse the minutes.
