First you'll need:
- A Google Voice account. It's currently by invitation only. Look for a friend of you who has some invitations and buy him a bar of chocolate. (I have some invitations by the way ;))
- A Gizmo5 account. It's FREE. Just go to the website and create a free account.
- At Google voice account settings. You should add a phone number. Again you'll need some help from a friend. Give his number and make a test call where you hear the confirmation code and copy it from him. I think there are some programs that can give you a virtual phone number. I think localphone.com does this but I haven't tried it with them. Anyway feel free to solve this issue by any possible means.
- Now you can add a Gizmo5 phone number to your Google voice account. Add your Gizmo5 number at this point.
- At Gizmo5 account settings add your Google voice number. You'll figure out how as soon as you login to the website.
- Install guava on your Android phone.
To make free calls:
Make a call from your Android phone using Google Voice.
To receive free calls:
Simply let anyone call your Google voice number.
Hints:
- You don't need a SIM card in your phone to do this trick. Only using a WiFi is enough.
- If you don't have an Android phone. Theoretically, as I didn't try it, when you make a Google voice call you can receive the call from any Gizmo5 client like from your PC as an example. Or if Gizmo5 is supported on your phone you can download a client and that will be enough.
- Maximum call from your phone is 3 minutes and you can receive unlimited number of minutes.
- You can call USA using smartvoip for FREE. This will let you call your friends who are doing this trick for free on both sides.
That's all. I hope this helps. See you later :)
