Unless you shut off the cellular and do this over wifi with skype or what you listed it usually eats up your minutes faster than a horde of locusts.
American living in Europe for the next 3 years with a question.
I have an unlocked Iphone that has a 2gb / month plan with Vodafone Italy. Calling America from my Italian cell is incredibly expensive, but I don't go over the 2 gbs, and I'm wondering if there's an app (google voice, skype, etc?) that would let me call over data, without being charged minutes.
Any help would be awesome!
