International orange sim card?

I'm leaving the US To visit my family in Europe in two weeks and my moms friend told me to get the sim card out of my iPhone and put an Orange sim card in? I'm guessing its a prepaid sim card that ill be able to use over seas? I checked the website but it just confused me even more.

Does anyone know anything about these Orange sim cards? Price also?

SIM cards don't cost much, and are available in a lot of places overseas. Yes, Orange has prepaid plans and many people often do that when they go abroad. Also, unless your phone is unlocked, you won't be able to put in a foreign SIM into your phone. See about getting your phone unlocked first, and then you will be able to do it. You can call your carrier and tell them that you want to get your phone unlocked (be sure to tell them you are going overseas and that it's very important because carriers don't like to unlock phones because it means you can leave their service and go to another) and they'll help you with that.
