How to Remove a SIM from Samsung Galaxy S7, if inserted without tray
Improper SIM extraction can cause irreparable damage.
- For guaranteed results, use this method employed by Samsung technicians in Canada:
- Locate the SIM card slot and insert a plastic spudger or similar tool to release the SIM tray.
- Gently pull out the SIM tray without applying excessive force.
Step 1 | Remove Back Glass
Set hot air gun to adhesive melting temperature (e.g., 250°C).
- Heat four sides of back glass with hot air until warm.
- Apply suction cup for upward pressure, starting glass lift.
Use Ethyl Alcohol (99%) to break down adhesive in seam.
Step 2 | Remove Housing Panels
Remove the back glass.
- Take out the screws from the three housing panels.
- Use a spudger/pick to carefully pry off the clipped-in panels.
- Remove the three panels for clear access to the motherboard.
Step 3 | Remove Motherboard from frame
Be cautious when lifting the motherboard — risk of damage.
- Lift all connectors attached to the board, including the camera, screen, power button, network coaxials, fingerprint sensor, earspeaker, and prox/light sensors.
- When lifting the board, carefully lift from the top edge, avoiding the charge port at the bottom.
- As you lift the board out, disconnect the charge flex connector.
Step 4 | Remove Card from Reader
Be cautious: ensure the board has no power before proceeding.
- Use a small Slot Screwdriver to access SIM card openings in the reader.
- Slowly slide the SIM outwards until it can be comfortably removed from the device.
When handling metal tools on the board, destat them and handle with care: no rough movements or pressure.
Step 5 | Reassemble Device

- Reassembly is done in reverse order of disassembly.
- Check for any damaged or missing adhesion before proceeding.
