Spare Phone uses your WiFi,3G,4G data connection to place and receive Google Voice VoIP calls. All you need is the "Spare Phone" app, a data connection(Wireless or Mobile) and a free Google Voice account. Spare Phone transforms your Android phone or tablet into a free wireless phone when used over WiFi/Wireless in the USA and Canada!

Google Voice is currently free to place calls to the U.S. & Canada. Please visit to create a free Google Voice account and to get your free phone number. Also check out the great rates to other countries such as Mexico and India.

Note: To use 3G, 4G you must enable it in the settings of Spare Phone. This can be costly if you don't have unlimited data. Please verify that your cell carrier allows VoIP data traffic before enabling this option. This app uses ~1.2 MB per minute during a call.

Disclaimers: Google Voice is a product of Google, Inc. and "Spare Phone" is not in any way affiliated or endorsed by Google Inc.
WARNING: Google Voice does not support 911 or any other type of emergency calls!

Frequently Asked Questions:

1.) Does this use my cell phone minutes?
Answer: No, Spare Phone uses your wireless/data connection and your Google Voice account for calls. You don't even need cell phone service to use this app. Note: If you are not using WiFi you will pay for your cellular data usage.

2.) Is this a simple callback app?
Answer: No, this is a pure VoIP(Voice over IP) calling app that communicates directly without any additional latency. You DO NOT need a SIP client or callback app to place and receive calls.

3.) Will this work with an Android tablet?
Answer: Yes, Spare Phone will enable your Android tablet to place and receive calls. It will also work with Wi-Fi only tablets too.

4.) I'm not receiving incoming calls. Help!?
Answer: To receive incoming calls you must enable 'Google chat' as one of your phones to ring in the Google Voice settings. Just make sure you don't have the cell phone you're using and 'Google chat' enabled simultaneously.

5.) Calls seem to have issues when my screen turns off.
Answer: In the settings enable 'Keep Screen On' as some devices put the wireless connection to sleep when the screen is off.

    Although the call quality is not all that bad, every time I want to make a call to someone, I end up dialing twice as the first call gets no where. It is very irritating to say the least. This is not expected in a paid app.

    The addition on texting would make it perfect!

    Missed the deadline by probably not even one minute. Contacted the developer as soon as it happened. No response back. Installed on old Samsung president and it froze and missed the dead line.

    Slick, simple interface, lots of behind-the-scenes control if you want it. Compared to Talkatone, Spare Phone has better call quality, fewer connectivity issues, and fewer bugs. Spare Phone doesn't handle SMS, but Hangouts does that now.

    It's unfortunate that Google Voice is going away in May 2014 because I downloaded this app last night and it's the best VoIP I've found so far. This app is one that I wouldn't hesitate to pay $20 for if there was a free trial period to test it out first.
