Hello!!!
Good news! Stop paying expensive phone bills to call your friends and family abroad.
A few websites gives you cheap access numbers to call abroad (landlines and mobiles).
I suggest the following websites:
http://www.storytelecom.com/ (quite famous)
http://www.best4talk.co.uk/ (less famous, but straightforward)
http://www.best4roaming.com/ (great if you travel a lot)
http://www.cartesiminternationale.com/ (for french people)
