If you’re like most iPhone owners, you probably have a few old SIM cards lying around that you don’t need anymore. But before you can start using your new iPhone with a new SIM card, you first have to move your old SIM card to the new iPhone. Here’s how:

  1. Open the Settings app on your old iPhone and select General.
  2. Under “SIM Card,” tap on the “Remove” button next to the card you want to remove.
  3. Slide your old SIM card into the new iPhone’s corresponding slot and press “OK.”
  4. You’ll now be prompted to enter your Apple ID and password, which you’ll use to sign in to your iCloud account on your new iPhone. If everything goes according to plan, your old phone number will also transfer over automatically! ..
