Pay No Attention to Emergency Features
By now, you’ve probably heard of Apple Watches saving lives. But your iPhone can also come in handy during an emergency situation, too.
For example: Emergency SOS, which you can activate by holding down the Side button and a Volume button. (On iPhone 7 and earlier, just rapidly press the Side or Top button five times). From there, just tap Emergency SOS.
The other is Medical ID, which you can set up in the Health app by tapping your profile icon and then Medical ID.
From here, you can enter medical information that will be accessible to first responders — even if your iPhone is locked. You can also set up emergency contacts. Their data will show up on the Lock screen and they’ll be alerted if you use Emergency SOS.
