    • Insert a SIM card eject tool, a SIM eject bit or a straightened paper clip into the hole on the SIM tray located at the left side of the phone.

    • Press firmly to eject the tray.

    • Remove the SIM card tray.

    • When reinserting the cards, make sure to properly orient them in the tray.

  2. Battery Disconnect, Back Cover: step 2, image 1 of 1
    • Before beginning this procedure, completely power off your phone.

    • Prepare an iOpener and apply it to the back cover to soften the adhesive.

    • The adhesive of the Samsung Galaxy A51 is very strong. You can use a hair dryer or a heat gun if you aren't able to open the device with the iOpener.

    • Be careful not to overheat the phone—the AMOLED display and internal battery are both susceptible to heat damage.

    • Insert the tip of an opening pick between the frame and the back cover at the bottom of the phone near the USB-C port.

    • If you can't get between the back cover and midframe with your opening pick, you can use a suction handle or strong tape to pull up the back cover to create a gap.

    • Slide the opening pick to the bottom right corner and leave it there.

    • Slide the opening pick along the left edge of the phone.

    • Leave the opening pick in the top left corner to prevent the adhesive from resealing.

    • Remove the back cover.

    • After installing the back cover, apply strong, steady pressure to your phone for several minutes to help the adhesive form a good bond—a stack of heavy books works well.
