Set up iPhone Emergency SOS for automatic calls and messages
An iPhone can call for help and alert chosen people after a severe crash, but those functions need configuring beforehand. On supported iOS versions, Emergency SOS uses Crash Detection to start a countdown, call Australia’s 000 emergency number and send a location alert to selected emergency contacts. Automatic Call and Messages controls determine which actions can happen without manual intervention.
This guide explains the setup, testing process and Australian-specific considerations. Menu names can vary slightly between iOS releases, so check the wording on your own device. Emergency SOS is designed for serious situations such as severe vehicle crashes and certain falls; it is not a substitute for emergency assistance, medical monitoring or safe driving.
Compare the emergency options
Emergency SOS includes several complementary features. Crash Detection recognises a severe incident, while manual Emergency SOS lets you initiate help by pressing the required buttons. Automatic calls, automatic contact messages and satellite support depend on the phone model, iOS version, location and available network.
| Option | When it activates | Connection needed | Information sent | Main limitation |
|---|---|---|---|---|
| Manual Emergency SOS | You deliberately press the side and volume buttons | Cellular network, with satellite support where eligible | Emergency services receive the call and available location | Requires time and physical movement |
| Automatic emergency calls | Supported iPhone detects a severe crash | Cellular network; satellite may apply in supported locations | Local emergency services receive a call and location | Only certain serious incidents qualify |
| Automatic contact messages | Supported iPhone detects a severe crash | Cellular, Messages or eligible satellite service | Selected contacts receive an alert and location information | Delivery depends on the network and selected contacts |
| Emergency SOS via satellite | Cellular coverage is unavailable and the feature is activated | Satellite connection | Emergency services or selected contacts receive the request | Requires supported hardware and a reasonably clear view of the sky |
In Australia, 000 remains the primary number for police, ambulance and fire services. Mobile phones can also use 112, which routes to the appropriate Australian emergency service, while 106 provides textphone access for people who are deaf or have hearing or speech difficulties. Outside Australia, an iPhone normally selects the emergency number used in the country associated with its SIM or eSIM.
Prepare the iPhone
Begin with current software and suitable hardware. Open Settings > General > Software Update, install any available iOS update, then return to Settings > Emergency SOS. Crash Detection works on several iPhone 11-and-newer models, but automatic calling and messaging have narrower device and regional support. The presence of the Automatic Call and Messages controls is the most reliable indicator on your handset.
Set a passcode before relying on Emergency SOS. Add emergency information under Health > Medical ID, including medical conditions, allergies, medications, blood type and relevant emergency contacts. Share Medical ID during emergencies only when you trust the people selected, because authorised contacts may be able to view sensitive health details from the lock screen.
If you are considering a replacement handset, separate confirmed specifications from rumour before choosing a model. Zack Michaels’ iPhone 16 Ultra claims analysis shows why leaked hardware details should not replace checking current iOS compatibility and regional support.
Enable automatic calls and messages
Open Settings, select Emergency SOS and turn on the main Emergency SOS switch. Under Automatic Call and Messages, enable Call Emergency Services and Message Emergency Contacts. Choose one or more recipients for the message alert, tap Done and confirm any prompts. If the automatic options are missing, check for another iOS update and confirm that the phone model supports them in Australia.
After Crash Detection recognises a severe incident, the iPhone sounds an alarm and displays a countdown. If the countdown finishes, the phone calls 000 and makes an available location estimate available to the operator. You can cancel only when you are safe and able to do so. The emergency operator decides how to respond, so answer questions and remain on the line if connected.
Automatic contact messages provide a second layer of notification. Selected people receive an alert containing available location and incident information, although the exact content and delivery method can depend on iOS, the phone and network conditions. This is an emergency message rather than a continuous live-tracking service, so contacts may not be able to monitor movement after receiving it.
Choose reliable emergency contacts
Choose at least two people who are unlikely to be affected by the same incident. Suitable contacts might include a partner, adult family member, neighbour or trusted friend. In a city such as Sydney or Melbourne, someone outside your immediate household may have better access to the scene. For regional travel, consider a contact with suitable transport, satellite communication or knowledge of the local area.
Check that every contact can receive messages and that their Australian mobile number is correct. A contact who works only during business hours, lacks mobile reception or has not seen a Messages alert is less useful. Check both the emergency-contact list attached to the automatic message and the separate emergency contacts listed in Medical ID, because updating one does not necessarily update the other.
Location can reveal your home, workplace, current route and travel patterns. Australian organisations handling personal information are subject to the Privacy Act 1988, while individuals can still misuse information shared privately. Discuss the alert with trusted contacts, keep the list limited and review it whenever a number, relationship or work arrangement changes. Do not add clients, colleagues or acquaintances merely to create a longer list.
Understand the emergency response sequence
A supported iPhone first detects a possible severe crash, warns the wearer and starts a short countdown. Automatic calling then places a call to the relevant local emergency number, using GPS, cellular and Wi-Fi information to improve the location estimate. Keep the phone reachable and do not rely on moving it to a hand if the vehicle or your body is trapped.
Recent iPhones sold in Australia can use Emergency SOS via satellite when cellular coverage is unavailable. Automatic contact messaging may use the satellite pathway on eligible devices when the relevant options are enabled. A clear view of the sky is useful, but hills, dense vegetation, heavy rain and buildings can reduce reliability. Satellite communication can also take longer than a conventional mobile connection.
The 000 service is an Emergency Telephone Service under the Australian Communications and Media Authority’s framework and the Telecommunications Act 1997. Mobile providers can supply location information to the appropriate emergency service point. Australian road rules generally require drivers to stop after a crash and provide assistance where it is safe to do so; call 000 when anyone is injured or serious damage makes an emergency response necessary.
Test settings and plan for edge cases
Verify the configuration without creating a genuine emergency. Reopen Settings > Emergency SOS, confirm both automatic actions remain enabled and check that the correct recipients appear beside Message Emergency Contacts. Send a normal message to each person and ask them to confirm receipt and view the shared location. There is no supported consumer method for safely testing Crash Detection, so avoid deliberately crashing or using unofficial crash-test applications.
Network and battery conditions can change the result. Check coverage maps from Telstra, Optus or Vodafone, depending on the SIM or eSIM in use, particularly around regional highways and national parks. A phone with little charge, an active temperature warning or a damaged side button may not complete every action. 112 can provide an alternative mobile emergency route, and satellite features offer another pathway only on eligible hardware with a usable signal.
International travel also changes the emergency details. Australian travellers need the local numbers rather than assuming 000 will work. In Vietnam, for example, 113 reaches police, 115 reaches fire services and 114 reaches ambulance services. For Australian travellers, QL-1 convoy guidance illustrates the value of checking route and traffic conditions before a remote journey, while your iPhone’s setup supplements rather than replaces local advice.
Keep emergency access ready
Review Emergency SOS after major iOS updates, phone replacements and changes to your contact list. Keep the phone sufficiently charged before long drives, carry a suitable cable or power bank and avoid cases that make the side and volume buttons difficult to press. In regional Australia, download maps for offline use and tell your emergency contacts which route you expect to take when ordinary reception becomes uncertain.
Households should agree on a primary and secondary contact, including someone who can reach the driver’s home or workplace. Workers using company phones should confirm that contacts can call a personal number, while frequent travellers should keep roaming and satellite coverage in mind. Australian privacy habits matter here too: a precise location alert should go only to people who need it and understand how to respond.
Open Settings now, enable Emergency SOS, turn on both automatic actions, select at least two trusted contacts and send one test message. Your iPhone will then have a clearer route to emergency assistance and the people most likely to reach you when every second matters.
