Still, in my last bill I found ATT charged me our $3 per minutes for a call I made using Skype credit and Skype app. I've been using Skype credit to make international call and I did (actually twice) called ATT customer service and requested my international outbound calls to be blocked. Your mobile operator might charge you for data when you use the app over 3G or 4G." Yes, you can run Skype for Android and use all of its features over 3G, 4G, and WiFi. Indeed, what's the point of even using Skype if it's going to connect someone to AT&T's cellular voice network (at $3.50 a minute) when things go south with the connection? That would be a bit of false advertising if it is telling us it we can call Australia from its Skype-for-mobile app for 2.3 cents/minute? My husband and I have used Skype for years this way to call Australia. It's going over the Internet, not cellular voice. That's the whole point of using Skype rather than your cell phone! On the US side, you are also paying any marginal cost of data charges (data allowance), not US cellular voice charges.

When you go from Skype to a landline, you pay 2.3 cents a minute to an Australian landline (with Skype credit as mentioned below) or 10 cents/min to Australian mobile, just so you can avoid AT&T charges of $3.50 a minute. Skype calls to landline and cellular lines are charged at Skype per-minute rates (paid for by Skype credits).
