Hey guys. I recently downloaded the wistle phone application. Great app and can be a great tool when on vacation and wanting to call the US. Question is... Although the app is free and you can make calls on it, what about the recipient? I looked at whistle phone rates and it appears the one you are calling will be charged for the call. Does anyone have some insight? I really dont want to make calls at my leisure only to find out i cost my family memeber hundreds of dollars for making the calls. Please advise
