I am going to France & Italy in the morning for 2 weeks. It was suggested that as opposed to using AT&T World Traveler... that I should use Skype with the Skype Out feature for making outgoing calls while I am there. Skype is 25 cents and AT&T is 99 cents. My question is this. If I use Skype, aren't I still using some part of AT&T to connect to some type of cell network? Does Skype use AT&T at all for anything? Any quick help would be greatly appreciated.
