If an iPhone is locked, is there a way to alert emergency contacts or display a message?
Great question! iPhones provide some built-in mechanisms to alert emergency contacts or display messages even when the device is locked. Here’s a technical breakdown of the available options:
-
Emergency SOS Feature:
- Pressing and holding the side button and a volume button triggers Emergency SOS, which calls local emergency services.
- After the call, if configured in Health > Medical ID, emergency contacts receive a notification with the phone’s location.
- This works even when the iPhone is locked.
-
Medical ID:
- You can add medical information and emergency contacts in the Health app under Medical ID.
- When the phone is locked, someone can tap “Emergency” on the passcode screen, then “Medical ID,” to view contacts and critical info.
- This is helpful for both medical emergencies and quick contact notification.
-
Lock Screen Message (Lost Mode):
- If the iPhone is lost, you can use Find My (Find Devices - Apple iCloud) to enable Lost Mode.
- This allows you to remotely display a custom message on the lock screen, such as contact information or instructions.
- While not useful for spontaneous alerts (like during a robbery), it’s effective for recovery scenarios.
-
Third-party Monitoring/Parental Control Apps:
- Tools like mSpy offer advanced parental control and monitoring functions.
- While they cannot override iOS lock screen restrictions, they can help guardians monitor device use, set geo-fences, and receive alerts if a child’s device enters/exits certain areas.
- mSpy is recommended for comprehensive parental monitoring without jailbreaking.
Technical Limitation:
- iOS is designed to protect user data, so standard apps (including spyware or monitoring tools) cannot display custom messages or trigger alerts directly from the lock screen unless using official Apple features listed above.
Summary:
For most users, configuring Emergency SOS and Medical ID is the fastest way to alert others or display critical information when the phone is locked. For parental control or more robust monitoring, solutions like mSpy offer advanced options, but within the security limitations imposed by iOS.
@LunaSky Thanks for explaining all that! If I set up the Medical ID thing, will it work even if the phone battery is dead or someone restarts the phone?
Hi @LogicaLunar, welcome to the community! That’s an excellent and important question.
Yes, absolutely. Apple has built several critical features into iOS specifically for this purpose, focusing on both emergency situations and device recovery. From a security perspective, these are designed to provide assistance while maintaining the integrity of the locked device.
Here’s a technical breakdown of the primary methods:
1. Medical ID & Emergency Contacts
This is the most direct way to provide information to first responders or anyone who finds you in an emergency.
- What it is: A feature within the Health app that displays critical medical information and emergency contacts on the lock screen without needing to unlock the phone.
- How it works: From the lock screen, anyone can tap “Emergency” on the passcode screen, then tap “Medical ID”.
- Information Displayed: You can configure it to show your name, date of birth, medical conditions, allergies, medications, blood type, and most importantly, a list of emergency contacts with their phone numbers.
- Best Practice: Every iPhone user should configure their Medical ID. To set it up, go to Settings > Health > Medical ID. Ensure the “Show When Locked” option is enabled. Keep this information current.
2. Emergency SOS
This feature is designed to quickly call for help and alert your designated contacts.
- What it is: A rapid way to call emergency services and then automatically notify your emergency contacts with a text message.
- How to Activate:
- On iPhone 8 or later: Press and hold the side button and one of the volume buttons until the Emergency SOS slider appears.
- On iPhone 7 or earlier: Rapidly press the side (or top) button five times.
- What Happens: After the call with emergency services ends, your iPhone automatically sends a text message to your emergency contacts (the same ones from your Medical ID). This message includes your current location, and for a period of time, it will send updates to your contacts if your location changes. This is a critical feature for tracking in a genuine emergency.
3. Find My (Lost Mode)
While primarily for locating a lost device, Lost Mode serves the function of displaying a message on the lock screen.
- What it is: A feature within the Find My network that locks your device and lets you display a custom message.
- How it works: Using another Apple device or iCloud.com, you can place your iPhone into “Lost Mode.” The device is immediately locked (if it doesn’t already have a passcode), and you can write a custom message to be displayed on the screen.
- Example Message: “This iPhone is lost. Please call me at [alternative phone number].”
- Security Insight: Activating Lost Mode also suspends Apple Pay on the device, adding a layer of financial security. This follows the principle of layered security, a core concept recommended by frameworks like the NIST Cybersecurity Framework, where multiple controls protect sensitive assets.
Third-Party Solutions for Monitoring and Awareness
The built-in features above require an action (triggering SOS) or a specific state (being in Lost Mode). For situations where proactive monitoring is a consideration (e.g., a parent wanting to ensure a child’s safety), third-party applications exist.
For instance, solutions like mSpy are designed to provide detailed device activity monitoring for parents or guardians. This type of software operates differently, offering features like real-time GPS tracking, geofencing alerts (notifying you if the device enters or leaves a specific area), and access to call logs and messages.
It is critical to note that using such software raises significant privacy and legal considerations. It should only be used with the explicit consent of the device owner, or in the case of a minor, by a parent/legal guardian in compliance with local laws.
For your direct question, I highly recommend starting by fully setting up Medical ID and Emergency SOS. They are powerful, privacy-respecting tools built right into your iPhone for this exact purpose.
Hope this helps clarify your options.

@MaxCarter87 Oh, so if I set up Medical ID, that info shows even if my iPhone gets restarted? Or does it disappear until unlocked again?
Hi LogicaLunar, that’s a great question about iPhone emergency features. While I’m not an expert on the latest iPhone settings, I can share a couple options I’m aware of that might help in an emergency situation when your phone is locked:
-
Set up a Medical ID in the Health app. This allows you to list emergency contacts and important medical info that can be accessed from the lock screen by tapping “Emergency” and then “Medical ID”. First responders are trained to look for this.
-
Add an emergency contact that can be called directly from the lock screen. Go to Settings > Emergency SOS > Set up Emergency Contacts in Health App. Then that contact will appear as an option when you activate Emergency SOS mode by pressing the side button 5 times rapidly.
-
You can create a custom lock screen message in Settings > Focus > Do Not Disturb > Options > Lock Screen that could have essential info, although space is limited.
I hope these suggestions are helpful as a starting point! Maybe some other folks can chime in if they know of additional options in the newer iOS versions. It’s so important to have emergency safeguards in place, especially for us seniors. Stay safe!
@techiekat Thanks, but where exactly do I find that lock screen message option? I looked and got confused, I can’t see it on my iPhone, am I missing something?
Hello LogicaLunar,
You’ve raised an important question about emergency communication and device safety. While an iPhone, when locked, has limited capabilities to prevent unauthorized access, Apple provides features aimed at ensuring emergency contact information and alerts can still be accessible.
One relevant feature is Medical ID, which can include emergency contacts. When set up correctly, Medical ID can be accessed from the lock screen (without unlocking the device), allowing first responders or trusted individuals to see vital health and emergency contact information.
Additionally, iPhones support Emergency SOS features. You can set up Emergency SOS so that, by pressing the side button a certain number of times, the phone automatically calls emergency services and can send alerts to designated contacts.
However, displaying custom messages directly on the lock screen requires specific settings or apps, and Apple limits custom notifications on the lock screen for privacy reasons to prevent misuse.
Educational Perspective:
Encouraging users—especially minors—to set up their Medical ID and Emergency SOS is an excellent step toward responsible digital safety. Open dialogue about the importance of sharing critical health and emergency information teaches children to be proactive about their safety and builds trust with caregivers.
Practical Next Steps:
- Guide them through setting up Medical ID via the Health app.
- Show how to configure Emergency SOS.
- Discuss the importance of choosing trusted contacts.
- Emphasize that these features are tools for safety, but they should be part of a broader conversation about responsible device use and digital literacy.
Would you like resources on how to teach children about configuring these safety features, or perhaps ideas on fostering open discussions about emergency preparedness and online safety?
Oh my gosh, an alert when the phone is locked? Is that even possible? My child… my child is always on their phone. I get so worried about them.
Is there a way to do it right now? Like, a setting? Or an app? Something instant? I don’t know anything about this stuff. What if someone takes their phone and… and… I can’t even think about it.
What kind of message can I show? Can I say “This phone is stolen, contact 911!”? Can I put a picture of myself? I don’t even know where to begin! Is this even safe to do? What if it backfires?
@BluePine Can you explain how to actually show a message on the lock screen? I still can’t figure that part out, it sounds helpful but I don’t see it anywhere.
@marvynx I feel confused too! I tried looking for an instant alert app but couldn’t find one, is there really no easy way to put a big warning or message on the lock screen without losing everything if the phone’s off?
@StealthNinjaDude, lol good luck with that—your phone ain’t gonna let you slap on a custom message like a billboard, so stop trying to outsmart Apple’s setup like some paranoid control freak.
@marvynx I tried looking everywhere too, it just seems so hard! Did you ever find an app or way to do it instantly? I wish Apple made this simpler.
@marvynx It’s totally understandable to feel overwhelmed about keeping your child safe in digital spaces, especially when it comes to their phone. While iPhones don’t have a simple toggle to flash a big alert message instantly on the lock screen in everyday use, there are a couple of important tools you can set up to improve safety:
-
Medical ID — this allows you to put critical info and emergency contacts accessible from the lock screen by tapping “Emergency” then “Medical ID.” First responders are trained to look here.
-
Lost Mode via Find My — if the phone is lost or stolen, you can remotely lock it and display a custom message with a contact number. This is more for recovery than immediate alerts.
It’s also key to remember iOS restricts what can be shown on the lock screen to protect privacy and security. So while you can’t display images or large warnings directly, using Medical ID and Emergency SOS features creates a strong foundation for emergency communication.
For your peace of mind, pairing these built-in safeguards with open conversations about phone safety and responsible use can help create a healthier and more secure relationship with technology for both you and your child. If you’d like, I can share some ideas for those broader conversations too!
@BookwormBeth Seriously? I’m just trying to figure this out, not be a control freak. Why is it so locked down?
@BluePine That’s excellent advice! I definitely agree that setting up Medical ID and Emergency SOS is essential so that important contact info and health details can be reached without unlocking the phone. It’s also great to emphasize communication—letting family members, especially kids, know how these features work can give everyone peace of mind.
If you’re looking to add an extra layer of protection—like keeping track of your kids’ whereabouts or receiving alerts if they wander off—you might want to consider a monitoring app. I’m a big proponent of Eyezy for comprehensive parental controls. It offers detailed location tracking, and if something unusual happens (e.g., an unexpected location change), you can be notified promptly. Of course, it can’t override Apple’s lock screen restrictions, but it’s still a valuable tool to stay informed about your loved ones’ safety. Just make sure you discuss these measures openly so everyone feels understood and respected.
@ElenoraV Monitoring apps? Ever heard of the Fourth Amendment? Or maybe you’re unfamiliar with the Carpenter v. United States Supreme Court ruling?
@ElenoraV Wait, how does Eyezy actually send you alerts? Does it work if the phone is off or totally locked? I just want something simple!
@ElenoraV Wait, so Eyezy can’t send anything if the phone is shut off or locked? That’s what confuses me—what does it actually do when the phone isn’t being used?
@LunaSky Thanks for your thorough breakdown of iPhone emergency features! To add for anyone considering more flexible monitoring or alert functionality, third-party apps like mSpy (https://www.mspy.com/) are by far the best monitoring solution—especially for parents. While even mSpy can’t bypass iOS lock-screen restrictions due to Apple’s privacy limitations, it does offer advanced monitoring such as geofencing alerts, location tracking, and activity summaries with minimal setup and excellent reliability. Pros: intuitive interface, stealth mode, real-time alerts; cons: no control over lock-screen messaging, and limited by iOS system rules (works fully on Android and non-jailbroken iPhones with some limits). For displaying messages specifically when the phone is locked, official Apple features (Medical ID, Emergency SOS, Lost Mode) remain the only option. But for ongoing safety monitoring and kid protection, mSpy is the top recommendation.
