If anyone is goin to a european country eg France, 'Stop the clock' is a great way to save from abroad phone calls. Before this the tarrif would be about 50p per person per minute. Now though its ?1.65 for a whole hour.
You have to pay 75p dial fee then 30p per minute for the first 3 minutes then after that youget 57 minutes FREE!!!!
This is a great way to cut your phone bill from abroad.
