I can't wait to make Skype calls over the WiFi at Starbucks, basically having AT&T pay for the calls they will not be able to charge me for.
Can someone please answer this question for me? Suppose I live in the US and my Skype account has a US address, if I am traveling abroad (say, in Europe) and I have WiFi access, can I then make a Skype call back to the US and have it count as a non-international (local) call?
It's 2.1 cents per minute to call any US phone number (excluding premium 1-900 type numbers) using Skype's pay-per-use service, no matter where in he world the originating Skype device happens to be located.
If you are using one of Skype's subscription services that provides unlimited calls to US phone numbers (some do, some don't), then you've got unlimited calls (subject to a fair use policy) to any US phone (also excluding premium 1-900 type numbers), and again, that is true regardless of where in the world the originating Skype device happens to be located.
(To preempt the next question somebody might ask:
If the US phone number you're calling happens to be associated with a mobile phone that is physically roaming overseas at the moment, then the same 2.1 cents per minute or unlimited usage still applies. The person receiving the call, of course, pays whatever rate their carrier requires for roaming.)
If you are using one of Skype's subscription services that provides an incoming phone number for conventional phones to call you, then you have unlimited incoming calling through that service, subject to a fair use policy, no matter where you are in the world. People calling you at that incoming phone number, will pay the same rate (airtime, long distance fees, etc) as they would have paid to call any conventional phone number located within the incoming number's registered geographic calling area, no matter where in the world you take your receiving Skype device.
