Use this guide to replace the SIM card reader in an iPhone 12 Pro.

  1. iPhone 12 Pro SIM Card Reader Replacement, Eject the SIM card tray: paso 1, imagen 1 de 2 iPhone 12 Pro SIM Card Reader Replacement, Eject the SIM card tray: paso 1, imagen 2 de 2
    • Insert a SIM card eject tool or a paperclip into the small hole in the SIM card tray, located on the volume button edge of the iPhone.

    • Press firmly to eject the tray.

  2. iPhone 12 Pro SIM Card Reader Replacement, Remove the SIM card tray: paso 2, imagen 1 de 3 iPhone 12 Pro SIM Card Reader Replacement, Remove the SIM card tray: paso 2, imagen 2 de 3 iPhone 12 Pro SIM Card Reader Replacement, Remove the SIM card tray: paso 2, imagen 3 de 3
    • Remove the SIM card tray from the iPhone.

    • The SIM card will fall out of the tray easily.

    • When reinserting the SIM card, make sure it's in the proper orientation inside the tray.

    • A thin rubber gasket around the SIM tray provides water and dust protection. If this gasket is damaged or missing, replace the gasket or the entire SIM tray to protect your iPhone's internal components.

  3. iPhone 12 Pro SIM Card Reader Replacement, Remove the pentalobe screws: paso 3, imagen 1 de 1
    • Caution: Before you begin, discharge your iPhone battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.

    • Power off your iPhone before beginning disassembly.

    • Remove the two 6.75 mm long pentalobe P2 screws at the bottom edge of the iPhone.

    • Opening the iPhone's display will compromise its waterproof seals. Have replacement seals ready before you proceed past this step, or take care to avoid liquid exposure if you reassemble your iPhone without replacing the seals.

  4. iPhone 12 Pro SIM Card Reader Replacement, Heat the lower edge of the iPhone: paso 4, imagen 1 de 1
    • Heating the lower edge of the iPhone helps soften the adhesive securing the display, making it easier to open.

    • Use a hairdryer or heat gun or prepare an iOpener and apply it to the lower edge of the iPhone for about a minute in order to soften up the adhesive underneath.

  5. iPhone 12 Pro SIM Card Reader Replacement, Apply suction cup(s): paso 5, imagen 1 de 2 iPhone 12 Pro SIM Card Reader Replacement, Apply suction cup(s): paso 5, imagen 2 de 2
    • The next two steps demonstrate the iSclack, a handy tool that we recommend for anyone doing frequent repairs. If you aren't using the iSclack, skip down two steps for an alternate method.

    • If the plastic depth gauge is attached at the center of the iSclack, remove it now—it's not needed for larger iPhones like the iPhone 12 Pro.

    • Position the suction cups near the bottom edge of the iPhone—one on the front, and one on the back.

    • Press both suction cups firmly into place.

    • If your display or back glass is badly cracked, covering it with a layer of clear packing tape may help the suction cups adhere. The iSclack also includes two pieces of tape for this purpose.

  6. iPhone 12 Pro SIM Card Reader Replacement, Lift the display slightly: paso 6, imagen 1 de 3 iPhone 12 Pro SIM Card Reader Replacement, Lift the display slightly: paso 6, imagen 2 de 3 iPhone 12 Pro SIM Card Reader Replacement, Lift the display slightly: paso 6, imagen 3 de 3
    • Hold onto your iPhone securely and close the handle of the iSclack to slightly separate the screen from the rear case of the phone.

    • Don't try to completely separate the screen; a small opening along the bottom edge is all you need.

    • Insert an opening pick into the gap under the display on the lower edge of the iPhone.

    • Skip the next two steps.

  7. iPhone 12 Pro SIM Card Reader Replacement, Apply a suction cup: paso 7, imagen 1 de 2 iPhone 12 Pro SIM Card Reader Replacement, Apply a suction cup: paso 7, imagen 2 de 2
    • If you're using a single suction handle, apply it to the bottom edge of the phone, while avoiding the very edge of the glass.

    • If your display is badly cracked, covering it with a layer of clear packing tape may allow the suction cup to adhere. Alternatively, very strong tape may be used instead of the suction cup. If all else fails, you can superglue the suction cup to the broken screen.

    • Pull up on the suction cup with firm, constant pressure to create a slight gap between the front panel and rear case.

    • Insert an opening pick into the gap.

    • The watertight adhesive holding the display in place is very strong; creating this initial gap takes a significant amount of force. If you're having a hard time opening a gap, apply more heat, and gently rock the screen up and down to weaken the adhesive until you create enough of a gap to insert your tool.

  9. iPhone 12 Pro SIM Card Reader Replacement, Separate the screen adhesive: paso 9, imagen 1 de 3 iPhone 12 Pro SIM Card Reader Replacement, Separate the screen adhesive: paso 9, imagen 2 de 3 iPhone 12 Pro SIM Card Reader Replacement, Separate the screen adhesive: paso 9, imagen 3 de 3
    • Slide the opening pick around the lower left corner and up the left edge of the iPhone, slicing through the adhesive holding the display in place.

    • Don't insert the pick very far, or you may damage the display cables along this side of the iPhone. Insert it only a few millimeters, or about the width of the display bezel.

  10. iPhone 12 Pro SIM Card Reader Replacement: paso 10, imagen 1 de 3 iPhone 12 Pro SIM Card Reader Replacement: paso 10, imagen 2 de 3 iPhone 12 Pro SIM Card Reader Replacement: paso 10, imagen 3 de 3
    • Re-insert your pick at the bottom edge of the iPhone, and slide it up the right side to continue separating the adhesive.

    • Don't insert the opening pick too far into the iPhone, or you may cause damage to internal components.

  11. iPhone 12 Pro SIM Card Reader Replacement: paso 11, imagen 1 de 3 iPhone 12 Pro SIM Card Reader Replacement: paso 11, imagen 2 de 3 iPhone 12 Pro SIM Card Reader Replacement: paso 11, imagen 3 de 3
    • The top edge of the display is secured with both glue and clips.

    • Insert your pick into the right edge of the phone. Slide it around the top-right corner and across the top edge.

    • Again, don't insert the pick more than a few millimeters—about the width of the display bezel—or you may damage the front panel sensor array.

  12. iPhone 12 Pro SIM Card Reader Replacement, Open the iPhone: paso 12, imagen 1 de 3 iPhone 12 Pro SIM Card Reader Replacement, Open the iPhone: paso 12, imagen 2 de 3 iPhone 12 Pro SIM Card Reader Replacement, Open the iPhone: paso 12, imagen 3 de 3
    • If you haven't removed your suction handle or iSclack, remove it now.

    • Open the iPhone by swinging the display up from the right side, like the front cover of a book.

    • Don't try to fully separate the display yet, as several fragile ribbon cables still connect it to the iPhone's logic board.

    • Lean the display against something to keep it propped up while you're working on the phone.

    • During reassembly, lay the display in position, align the clips along the top edge, and carefully press the top edge into place before snapping the rest of the display down. If it doesn't click easily into place, check the condition of the clips around the perimeter of the display and make sure they aren't bent.

    • Remove two 1.1 mm long Y000 screws securing the battery and display connector cover.

    • Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from to avoid damaging your iPhone.

    • During reassembly, this is a good point to power on your iPhone and test all functions before you seal the display in place. Be sure to power your iPhone back down completely before you continue working.

  13. iPhone 12 Pro SIM Card Reader Replacement, Remove the battery connector cover: paso 14, imagen 1 de 1
    • Remove the cover.

  14. iPhone 12 Pro SIM Card Reader Replacement, Disconnect the battery: paso 15, imagen 1 de 2 iPhone 12 Pro SIM Card Reader Replacement, Disconnect the battery: paso 15, imagen 2 de 2
    • Use a spudger or a clean fingernail to pry the battery connector up from its socket on the logic board.

    • Try not to damage the black silicone seal surrounding this and other board connections. These seals provide extra protection against water and dust intrusion.

    • Bend the connector slightly away from the logic board to prevent it from accidentally making contact with the socket and providing power to the phone during your repair.

  15. iPhone 12 Pro SIM Card Reader Replacement, Disconnect the display cable: paso 16, imagen 1 de 2 iPhone 12 Pro SIM Card Reader Replacement, Disconnect the display cable: paso 16, imagen 2 de 2
    • Use a spudger or a fingernail to disconnect the display cable connector.

    • To re-attach press connectors like this one, carefully align and press down on one side until it clicks into place, then repeat on the other side. Do not press down on the middle. If the connector is misaligned, the pins can bend, causing permanent damage.

  16. iPhone 12 Pro SIM Card Reader Replacement, Disconnect the digitizer cable: paso 17, imagen 1 de 2 iPhone 12 Pro SIM Card Reader Replacement, Disconnect the digitizer cable: paso 17, imagen 2 de 2
    • Use a spudger or a fingernail to disconnect the digitizer cable connector.

    • If any part of your screen doesn't respond to touch after your repair, disconnect the battery and then re-seat this connector, making sure it clicks fully into place and that there's no dust or other obstruction in the socket.

  17. iPhone 12 Pro SIM Card Reader Replacement, Unscrew the front sensor connector cover: paso 18, imagen 1 de 1
    • Use a Y000 driver to remove four screws securing the front sensor connector cover.

    • Three 1.1 mm-long screws

    • One 1.4 mm-long screw

    • Swing the cover up from the left until the small clip on the right unhooks.

    • Remove the cover.

    • During reassembly, insert the clip on the right edge into its slot first, then hinge the rest of the cover into place.

  19. iPhone 12 Pro SIM Card Reader Replacement, Disconnect the front sensors: paso 20, imagen 1 de 2 iPhone 12 Pro SIM Card Reader Replacement, Disconnect the front sensors: paso 20, imagen 2 de 2
