How eCall works
eCall is a simple yet effective technology that saves lives by reporting incidents from the vehicle.
In simple terms, eCall is like a sleeping emergency phone with collision detection sensors installed in your vehicle. It only activates when the vehicle detects an incident, or the red SOS button is pressed.
eCall has one job, to call 999/112 when it wakes up. It will automatically make the call and send a small set of eCall data to the operator. The 999/112 operator will answer the call, get the data, and speak with you using the built-in eCall microphone and speaker. The data will include your vehicle’s unique identity (the VIN), what type of fuel it uses, and your last known location. It does not include speed or any personal information about you.
Usually, the operator will pass your call to the Police or equivalent in your country, who will then ask you what has happened and arrange for help to be sent.
eCall is automatically activated when the vehicle detects an incident. Each manufacturer will decide the best way to do this, but it usually includes airbags going off, or rapid deceleration. We’ve heard many stories from drivers involved in incidents who are surprised to quickly hear someone asking them if they need Police, Fire or Ambulance. That’s eCall in action, calling the emergency services for you.
You can also activate eCall by pressing the red SOS button. Sometimes it’s under a guard and sometimes you need to press and hold it for a couple of seconds.
eCall is dormant until it activates. The eCall unit contains a SIM card (or software equivalent) that will use any mobile phone network to make the call. So as long as there is mobile phone coverage in the area, even if just one network, the call will get through. Until it is activated no-one can connect to the eCall sim, and no-one can track you.
eCall is a European Union safety standard for any vehicles brought on to the market since 2018. Most new vehicles have it installed.
Some companies also provide kit to add eCall to older vehicles. These typically use mobile phone apps to make the call, connected to dashcams to detect the incident. Some may also use the mobile phone to detect the incident, but these can be susceptible to more false alarms, such as from rollercoasters and mosh-pits.
