nope you won't. but if you have some contacts stored in the sim card,you can go to settings> mail, contacts, calenders and Import sim contacts and just to be sure you can back up phone and change to the new sim card

iPhones do not save anything to SIM card.
Everything on the phone is saved to internal storage.
