Check out Talkatone. You get your own number which is synched to your contacts list. You can call from anywhere in the world (with a decent wifi connection) to any phone in the U.S. or Canada FREE!!! You get 10 free minutes a month and if you need more time you can buy 60 minutes for .99. When I say any phone in the U.S. or Canada I mean exactly that. Landline or cell phone. And people back in the U.S. can call you free as well. I also believe that you can call someone in another country if they also have Talkatone. Check it out. Oh and you can use your Talkatone number if you want to call someone normally but don't want the person you're calling to know your regular cell number.
