Make Calls Over Wifi Only With Your Outdated Smart Phone

Outdated smart phones are still useful for making phone calls, and best of all it can be totally free! Skype is the first that comes to mind, then of course there is Facebook and Google Voice which are both 100% free, person-to-person phone calls anywhere in the world. So long as you have wifi access, you don’t need a cell phone plan anymore!
