Android + Google Voice + GUAVA = SIM-Free calling options?

Google Android device owners who have accounts from both Google Voice and Gizmo5.com may be able to make and receive phone calls even if they don’t have a SIM card in their device. An experimental app named GUAVA, which stands for GoogleVoice Unauthorized Android Voice Application, links Google Voice and Gizmo5 accounts, allowing consumers to make calls without using their network minutes or even a SIM card.

I’ve heard of Android users adding their GV number to T-Mobile myFaves for more free calls, but this is one of the first solutions I’ve found for non-myFaves subscribers. In fact, GUAVA bypasses carriers altogether by connecting to Wi-Fi networks and delivering contract-free communication to:

  • Cell phones and landlines
  • SMS messages
  • Skype users
  • GoogleTalk users

NOTE: I was able to receive several free calls and SMS messages while testing the app; however, outgoing calls require purchasing call-out credits from Gizmo5.

The GUAVA/Google Voice link may prove useful to travelers or people who cannot find access to their network. I have visited friends and family members in areas where T-Mobile connections were not present whatsoever. This may come in handy if I find myself in a similar situation and have an Internet connection available.

Download GUAVA for Android from Gizmo5 and follow this tutorial to get it running. PLEASE BE ADVISED that you must give GUAVA your Google credentials.
