Useful discovery..

[green_amber]

This site lets you compare roaming charges for every operator and every country you're going to. So I've discovered that T Mobile are half the price of Orange for roaming calls in America - a pretty good selling point.

However I was actually trying to comapre DATA roaming charges and I can't seem to make the site do that - anyone clverer than me?
EDIT: got it. Stoopid site - they do roaming calls by country but roaming data by operator!
