You may have heard of the new AT&T add-on called A-List that gives you unlimited calls to and from 5 numbers of your choice. Thanks to a little bit of thinking outside the box, and mostly thanks to Google Voice, you can actually get unlimited calling to any numbers in the US.

For those of you who don’t know how Google Voice works, let me explain briefly. Google Voice gives you a free phone number that entitles you to free calls in the US (and very cheap calls overseas). If you try to make a call from the Google Voice app on your iPhone (or the web-based version), Google Voice will call you at your number and connect you to the number you dialed. I’m not sure if that makes sense but basically, when you use Google Voice for calls, you don’t get free calls, minutes are taken off your plan, which kinda defeats the whole purpose.

Here is how the loophole works. Simply add your Google Voice number to your A-List. Now every time Google Voice calls you to connect the call with the dialed number, it will be free of charge and you’ll be able to call anyone in the US for free (really free).

I’m not sure this is very clear but Google Voice users will surely understand and see the benefits of this little trick. Let’s just hope AT&T doesn’t figure this one out and puts an end to it.

Do you use Google Voice? If so, you should definitely look into it…
