You may be frugal like me, or you may just consider yourself a cheapskate and not want to purchase any apps. Well if that’s the way you are, than this paid app is for you.
“GrooVe IP” is an app that uses voice over IP (Voip) technology to link your Google voice number to the outside world. This simply means that with an active Google voice number you can make calls to phone numbers in the USA and Canada FOR FREE. You just install the app, tell it your Google voice information and place a call.
It works (personally tested) on a non active phone and a tablet. So if you never pay for an app this app is for you. Save yourself a ton of money by making free calls over wifi, or 3g/4g, without using your phone plans minutes.
