One Important Warning

Because the hole is so small, some people mistake it for the SIM card tray opening.

Never insert a pin, needle, or other sharp object into it. Doing so could damage the microphone or other internal components. Before using a SIM-eject tool, always check your phone’s manual or look for the outline of the SIM tray.
