Use netTALK for "Free" Long Distance on Your Smartphone
written on Sunday, February 13, 2011 by Larry Chen
Hate paying for long distance when you're abroad or out of town?
There's a solution for that.
If you have a fancy iPhone (or iPod Touch or iPad), some sort of Android phone, some sort of BlackBerry or some sort of phone that is a Windows Mobile phone, there's an app for that situation.
It is important to note that if you have a smartphone, the phone will not use your minutes. Instead, it uses your data (make sure you have some sort of data plan) or Wi-Fi.
