Three got a little bit better - no roaming charges whatsoever in a number of European countries (i.e. no data cap on my plan). It was really handy to not have to worry about loading google maps and local websites while out and about in Italy this summer. Hopefully the list of countries will keep increasing.
Three actually recently announced a similar thing to this, whereby you take your contract with you to any country that Three operates in, i.e. Australia, Italy, Denmark, Austria, Sweden, Hong Kong and the Republic of Ireland. Other European countries and you still have to pay their standard European roaming charge...
