Hi
This is how it should work, you phone FROM SCOTLAND from your VODAPHONE to another VODAPHONE, it should just be using your free minutes, as YOU are not to know where the receiving VODAPHONE is are you?
However knowing the mobile industry as we all do the best advice I can give you s to ring VODAPHONE and check, if the dim wit on the other end doesnt know or says " I tink so" then make sure they check and try to get it confirmed by a supervisor or somewhere perhaps on the web, as its to late when you get the bill.
Hope this helps a bit ;-)
