Unlike the Verizon iPhone 4, the Verizon iPhone 4s does have a gsm radio and micro sim card slot, and can be used internationally - like any Verizon world phone, it has a Vodafone sim built-in and can be unlocked by a customer with 60 days of service. However, in this case that doesn't matter much, because I believe it is still locked in the US and cannot be activated on a US carrier, prepaid or postpaid.

However, if it was bought off-contract, at full price, the sim should be unlockable.
