We do it all the time through the Skype app....
...install Skype if you do not already have it
...put your phone in airplane mode(should already be on this from your point of departure)
...turn on wifi
...open Skype and you are good to go
Average cost is 2-3 cents a minute to call most countries...cells are a bit higher but still less than 20 cents
We used it in France and SXm to call the USA and at home to call France..
No worries about any International plan and charges BUT you need a wifi signal. It won't work on the move...
