Phoning home for free...

Google Hangouts is a pretty amazing and quite free way to call home via Wi-Fi on either a tablet or a cell phone that uses Wi-Fi. I am calling California consistently from Greece, Sweden and Hungry and have not incurred one cent of a charge for my calls! 

I think the secret is you need to establish the account in your home area code and then it thinks you're calling your home area code every time you're out of your area on Wi-Fi and therefore you get no charge for calling international calls. 

Of course there are other VOIP calling services that also will not charge for Wi-Fi calling. I was just under the impression that the Google service was going to cost a few cents each minute. Apple computer, iPhone and iPad users can also use iMessage and FaceTime over Wi-Fi for free as well. Skype is an alternative for many platforms too. I'm sure many PC and Android options are available as well. I'm just not as familiar with those platforms.
