Can i put a sim card on a verizon iphone 4?

Ok i have an verizon Iphone 4 that i want to use in italy, once in italy i want to put the italian sim card, BUT, my question is,
ok you know that the verizon iphone 4 doesn't have a sim card slot? There's none.
so i want to know if maybe opening my iphone maybe there's a place to put a sim card? Anyways, what i want to know is if i can use my verizon iphone 4 overseas with a different sim card.

You can switch out your sim card in your iphone and use it in Italy. With iphones it is a pain to get the sim card out though.

NO, Verizon iPhone 4's are cdma only, and only gsm phones use sim cards. That phone can never be used on a gsm mobile network, sorry.

You can't put ANY sim card in a phone not designed to use sim cards.never.

The Verizon iPhone 4 is CDMA and does NOT support SIM cards. The Verizon iPhone 4s is global and WILL support SIM cards.
