Spare Phone - Make and receive VoIP phone calls over WiFi!
Phone calls without using cell phone minutes!

If you follow the steps in the apps built-in 'setup wizard' you'll be able to make and receive 100 percent VoIP calls over WiFi or 3G/4G/LTE mobile data with zero cell phone minutes used! If you need any help I would kindly request that you contact me via email before leaving negative feedback as I actually take pride in this app!

Note: This app will be migrating away from solely using Google Voice mid-May(update: new version is now available). Incoming Google Voice calls will still be able to be handled by the app and the upcoming app update will guide you through the simple process. Outgoing calls will also be possible via Google Voice in addition to calls to other users of the app and toll free numbers will be included in the update too. The update offers great enhancements to the call quality as the app will now use a much improved audio codec. And many other exciting features are still in the works.

    Update changes a lot....set up is more complicated. Can't make out going calls like previous version. Now have to make calls through Google voice. Still tinkering with it. Rating may change.

    App no longer works as I originally paid for  it and I am not going to join some random untrusted service, which previously wasn't required when I paid, in order for this to work now. Please refund my purchase... Shame.... PLEASE REFUND

    Setting it up is now a whole new process due to Google voice changes. Ok fine. Not a problem. Who said software development was easy when you rely on third party. So I think the guy developed a new version to make it compatible as fast as he could.. In the rush, the favorites disappeared. I have to manually dialed each phone number to get a history....Can I have the favorite setup set up back???
