But my question was: what is the it that your phone has? I don't have such a button on my lock screen. There's a camera and a flashlight shortcut (too few shortcuts for my liking but better than bare android with zero shortcuts)

There is a large button underneath the number pad where you enter your PIN and it says Emergency Call. It works even when the SIM is still locked.

Ah, right yes that makes sense. I don't want to bother with entering a password on a device I use dozens of times a day so never set one, that explains why I don't see such a button: people can just get to the dialer if they need to call a number while I'm incapacitated
