Insert the SIM tool into the small hole on the side of the case until the tray pops out. Then remove the tray and set it aside.

If you're having trouble removing the tray, reinsert the SIM tool and gently pull the tray out with it until you can use your hands to remove it.

Use a JIS #00 to remove the single 2.3 mm screw that holds the metal bracket in place.

Remove the metal bracket that covers the press connector and set aside with its screw.

Place a spudger or an opening tool under the connector's edge and pry straight up to disconnect it.

Make sure to pry under the edge of the connector itself, and not under the socket on the board. Otherwise, you risk permanently damaging the socket.
