can anybody tell me how VOiP works. I know it allows you to make calls using WiFi, but my main question is if it is free to make those calls or not. Also, what would the number show up as. Thanks.
You can via skype. Works great, so far. If you subscribe to skypein, you get a phone number where people can call you from landlines. Only works when the app is running, though. Will go to voicemail otherwise. Not bad, I'm using it on my iPhone.
