I`ve been told that the 3 network works in Fance as if calling within the UK. The chap that told me called a mate in Italy who he speeks to every day on 3 at no extra cost to either party.When his pal traveled through France to Italy they did the same.He tops up his pals sim in UK cos it`s easier for him so I can`t see how he can be wrong about the whole thing. I am doubtfull. What do you think? Ps the far East also.
