Agreed, that's essentially what I was doing in the US, I just got it with a cheap phone too so I could keep my normal blackberry up and running with my UK number.

But stuff like the Vodafone deal within Europe are awesome, as it saves the hassle of needing either two phones or sim swapping.

I do the same. Cheap phone for local calls, and my normal phone for calls to/from home. What frustrates me is that even though dual-SIM phones have been around for years, no Western service provider will sell them, so none of the more popular smart phones support it.
