Apple Urges iPhone Users to Set Up 911 SOS and Medical ID

Q: Could the iPhone feature designed to save your life also expose your deepest medical secrets to a complete stranger?

Yes — but only if you choose to make it visible. Apple’s Medical ID is designed to be accessible in a crisis, and that creates a clear privacy tradeoff. If “Show When Locked” is turned on, anyone holding your iPhone can tap Emergency, then Medical ID from the lock screen and see whatever you entered there without your passcode. That can include allergies, medications, conditions, blood type, age, notes, and emergency contacts. So a stranger could see sensitive health details if they have your phone in hand. The same is true, in a more limited way, when “Share During Emergency Call” is enabled. In a real emergency, key medical details can be transmitted to 911 or emergency responders. On iPhone 14 and later, Emergency SOS via satellite can also share Medical ID, emergency contacts, location, and battery status when no cellular service is available. That does not mean the feature is unsafe by design. It means users must decide how much information is worth exposing to improve emergency care. Apple lets you control this. You can leave “Show When Locked” off, limit what you enter, or include only high-value facts such as severe allergies, diabetes, epilepsy, implanted devices, or medications that could affect treatment. The practical balance is simple: include only information a responder truly needs in the first minutes of an emergency, and review it regularly. The feature can save time and possibly lives, but it works by sacrificing some privacy in advance.

Apple’s latest iPhone safety guide tells users to configure Medical ID, emergency contacts and Emergency SOS before a crisis, stressing the tools are far less useful if left unset.
Since 2014, iOS has let first responders view Medical ID from the lock screen; users can add allergies, medications and conditions, and share that data during a 911 call.
Emergency contacts serve two roles: they can be reached by someone who finds the phone, and they automatically receive alerts and location data when Emergency SOS is activated.
Emergency SOS can call 911 by holding the Side and Volume buttons or, optionally, pressing the Side button 5 times; iPhone 14 and newer also support satellite emergency messaging when service is unavailable.
The guide also points users to Emergency Bypass, Text to 911 in supported U.S. areas, and crash detection options as part of broader iPhone emergency preparedness.
