skype on iphone abroad to skype on mac...free over 3g?

[icrude]

a few months ago I was on my iphone on skype over 3g and I called my friend in China and he was on skype on his mac and we talked for a bit and I was charged $25 from At&t for voice minutes.....wasn't skype to skype supposed to be free or is it different if they are on a mac and I am on an iphone? It doesnt say that anywhere....

My guess is it would have been free if you had been on WiFi, but you were on 3G and using data

 

[icrude]

using data? I have unlimited data...

Then it's no additional charge. Enjoy and have at it!

It shouldn't of cost unless they have a policy for fair usage or Skype.

Your best bet is probably to contact AT&T for an explanation of the charges
