Removing the nano-SIM card and the nano-SIM-card tray

Some models you are servicing might have a nano-SIM card installed. If the computer you are servicing has
a nano-SIM card installed, remove the nano-SIM card and the nano-SIM-card tray before you start the
servicing.
After you finish the servicing, ensure that you install the card and the tray back into the slot firmly.
