Face time

Having read some answers to the question re costs of face time, I am still unsure.
I am in Chile at the moment and contacted my daughter in the Uk yesterday. With my iPad to her iPhone.
Can anyone tell me if this will cost one of us and what the rate might be?

It's data, so if you were both on wifi, it cost you nothing.
