With the shutdown of the 3G network in Switzerland by the end of the year, switching to 4G or 5G is required to ensure the functionality of the eCall system. The shutdown of the old networks directly affects integrated emergency communication: Only newer vehicles compatible with current technologies can continue using this system.
**eCall - a system to save lives**
Since 31 March 2018, the emergency call service has been mandatory for cars and trucks registered in Europe and Switzerland. In the event of serious accidents, this system automatically establishes a voice connection between vehicle occupants and an emergency call centre. In 2024, the TCS handled more than 2,700 such calls. In the event of a collision, particularly when airbags are deployed, the vehicle automatically transmits important information: the time and location of the accident, type of powertrain, and number of belted occupants. Through voice communication, rescuers can better assess the situation and adjust rescue measures accordingly. eCall can also be manually activated by an occupant via an SOS button, ensuring emergency communication even if the alarm is not automatically triggered.
**The vehicle's manufacturing year is crucial**
Especially models manufactured before 2018 can be affected by the shutdown of the 3G network. Some manufacturers provide the option on their websites to check if a vehicle is affected and whether updates are available to continue using the eCall system. Authorised dealers and workshops can also provide this information. In vehicles equipped solely with 3G modules, the eCall system can no longer be used. For some older models, no updates are available, meaning that installed emergency systems are no longer operational. Retrofit solutions are available on the market, such as adapters for 12-V sockets (cigarette lighters). However, to forward calls to emergency numbers stored on the phone, these devices usually need to be connected to a mobile phone. Newer vehicles compatible with 4G or 5G can continue using eCall.
**What to do in an emergency**
In the event of an accident or emergency situation, help can be reached at the following emergency numbers: Police 117, Fire Brigade 118, Ambulance 144, and the general emergency number 112 (valid throughout the European Union). Additionally, TCS members can make geolocated emergency calls via the TCS app, which can be used from anywhere, such as on ski slopes or hiking tours. The app is free and automatically transmits the location during a call within Switzerland. In the event of a breakdown or accident, quick assistance is guaranteed.
**Quick help in emergencies** - Through emergency numbers 144, 118, 117, or 112 - With the TCS app, geolocated emergency calls (breakdown/accident assistance) can be made - The app is free and can be used everywhere, also when skiing or hiking. Within Switzerland, it automatically transmits the location with the emergency call.
