Does iPhone 3GS save contacts to sim?

Are they saved to sim card? I'm actually upgrading to the iPhone 4S and want to get my SIM card cut, so if I'm keeping the sim just getting it cut are contacts still going to be there?
How can I save them if they're not?

No. They are saved to the phone. You could backup the 3GS using iTunes & then restore from that backup on the 4S once you get it. Contacts would be part of that backup of course.

  • Will contacts save without SIM card? I just got a used IPhone 6 and I want to put in the contacts so I can use it soon. I'm getting the SIM card tomorrow, so I was wondering if I put my contacts in now, would they be saved and still there when I put my card in?

  • Where does the iPhone 3GS save SMS messages? I'd guess to the phone memory, only I'm putting my sim in a Nokia while I fix my iPhone, and I don't want the texts to carry over. Also will any texts I receive on the Nokia carry back over to the iPhone when I put my sim back in?
