As a US-based customer, I received both a US number based in my home state (Florida) as well as a UK number. With this sim loaded in unlocked Nokia E71, I was able to make local calls in the UK, as well as calls at lower roaming rates when in Spain and Germany. People in the US needing to reach me could do so by dialing the Florida number as a domestic call.
I'm a UK customer who's been trialling a SIM corporate account. I like them very much and they have brought down my data roaming charges significantly when travelling throughout the US.
Here's a long and in-depth review of their service.
It sounds like they don't provide as good a service to their individuals as to their corporate accounts, so you might want to factor that into your decision. Still, they go a long way to bringing the cost of roaming down and that should make up for it.
