Apple iPhone

When entering contacts to the iPhone, is there anyway to have them stored into the sim card?? The reason i ask this question is because my phone was swapped yesterday at an apple store and the guy told me that he was going to take my sim card out of the other iPhone and insert it into the new one, and that it was already going to be activated, and yes it was activated, but when i got home my contacts were not in the sim card, so i had to re-do all the entries again. So is there an option to store them to the sim card or not???
