Keep in mind: If you don't have an iTunes payment method properly setup, you will be asked for a credit card number before downloading the iOS app. This is Apple holding the payment information in the case a customer decides to click and agree to an "in-app purchase" or a paid download later in time. There is NO CHARGE to simply download the VoX iOS App, try the Free 60/60 to non-VoX users, and call other VoX users.
