This is a feature that I didn’t know existed until I accidentally started it. It’s incredibly useful in emergency situations and I think all iPhone holders should know about it. Also, please remember to fill out your Medical ID card (you can do so in the Health app).
nocallerid74: Doing this also disables Touch/FaceID, which can come in handy if the police wants to take a look at your phone. To re-enable Touch/FaceID, simply enter your PIN.
