Interestingly enough, T-Mobile US customers are our biggest downloads. It's free to call and text anyone that has the YR app. We give you $.25 credit which is enough for 25 mins of calls to the US from anywhere in the world or 25 text messages to people that don't have the app. Incoming calls are currently for a daily/weekly/monthly subscription but will be switched to $.03/min from anywhere in the world.
