I think I have made three international trips in the last three years and was always able to call home and friends (as long as there was wifi) for less than $20 combined. Love it and the fact that you use your normal smartphone and can program your caller ID so that it shows up as you calling and the people on the other end have no idea that you aren't using your normal calling plan. (note you can't receive calls without paying for a skype calling plan)
