Before we get started, you’re going to want to find a paper clip. That’s the easiest way to eject your SIM card without risking any damage. Next, locate your SIM card tray on your model iPhone using the following diagrams:

iPhone X, XS, XS Max

iPhone 4 through 8 Plus

iPhone 3GS and Original iPhone

To eject your SIM card:

  • Unwind one end of the paper clip so that it’s pointed out straight. Insert this end into the hold beside your SIM card tray.
  • Push in gently until the tray releases.
  • Before you remove your SIM card, take a look at where the notch is on your card; your new SIM card will need to face the same way.
  • Gently place your new SIM card into the tray in the correct position and pop the tray back into place!

You can save your old SIM card or throw it away. Before throwing away an old SIM card that has any personal data stored, make sure to destroy it by damaging the bronze foil on the back of the card. You can do this easily by scraping a sharp edge over the foil.
