Insert a straightened paperclip or a SIM ejector tool into the pinhole until you feel a slight click. Hold it down.

If you ever find yourself at a broken, flashing red room sign or a screen that reads "Authentication failed," you no longer need to call your IT admin or submit a support ticket. You have the verified steps right here.
