Free Calls From Your Cell Phone With Google Voice

If I can figure out how to invite people the first three people to comment will get an invite.

Most cellphone carriers provide a feature allowing you a certain number of contacts that you can call, on any network, for free, anytime. So what happens when you team up this feature with your Google Voice number?

The idea is that if you only use Google Voice to send and receive calls—and you set Google Voice so that it only displays your Google Voice number when it rings, all of your calls will be free, and you may never need to use another minute again. Each carrier is different, so we're looking at what each plan looks like, and how to use it with Google Voice to get free calls.

For this to work at all, head to Google Voice's Call Settings page and make sure Caller ID is set to Display my Google Voice number. (See the screenshot) Then just add your Google Voice number to your carrier's respective friends and family plan.

AT&T

AT&T just rolled out their feature, called A-List, and it is almost exactly the same as Verizon's. 5 or 10 numbers, depending on your plan, which has to be at least 900 minutes for individuals and 1400 for families. With AT&T you still have Rollover, too, so you get to keep the minutes that you save with Google Voice (in theory, at least—although, that hardly seems like it matters if you're not using any in the first place). You can update your list online, through your myWireless account on AT&T's web site.
