There is a SIM card slot on this phone. Verizon has an international plan that includes GSM service overseas or on demand.. but a lot of countries let you "rent" a SIM card while there and you should in theory be able to do this. We'll have to wait for someone to test.

Also the GSM radio is locked out of US GSM networks, don't know if that's going to change with a custom rom or not.. but if it did and you ponied up the coin to have a secondary account with AT&T or T-Mobile you would have the ultimate phone LOL

I also wish to know more about how it works... I suspect there is a "world phone" mode in which the phone favors GSM over CDMA.
