Important: Make sure to switch off
HTC One before removing the card.
Hold the phone face up and the top panel facing you.
Insert the tip of the tray eject tool (or a small bent paperclip) into the tray eject hole next to the
nano SIM card slot.
Push the tip all the way into the hole until the card tray ejects.
Pull the card tray out, and remove the
nano SIM card.
Make sure that you insert the empty card tray back into the slot.
