I forgot to mention I have a couple of sim cards from various countries in the EU that have generous roaming. Like Three UK which will give you essentially free roaming (but not calls and texts) certainly within the union, but also in places like the USA. It's not enough for tethering (indeed, it doesn't even work) but it's good enough for keeping internet on your phone for things like GPS, simple mail etc, holding you over between wifi hotspots.
