Thanks guys for all your replies. Will get in touch Kerry thanks, thanks for giving an idea of costs handy to know. I know a mobile would be useful though for me personally i know my friend several times has wanted to call me she is in Oz. I have been at work and when i have finished she is in bed, very difficult when you work shifts. I will also be working shifts over there and most of my friends and family work shifts so will def be better of with a mobile.
Thanks again for the info :)
