Besides ushering in the revolution of smartphones, 3G has played a foundational role in the navigation and alarm-based systems that we rely on during our everyday commutes. With the institution of faster and more reliable 5G, roadside assistance and emergency crash alerts are among the many network-based features that will be affected by the shutting down of 3G. Many cars also have an emergency SOS button that, when pressed, dials first responders via 3G. That, too, will lose functionality.
Vehicles from popular automakers like Toyota, Lexus, Nissan, Hyundai, Dodge, and more released before 2019 are susceptible to the issues mentioned above. The main reason that newer models still carry 3G receivers, according to Roger Lanctot, director of automotive connected mobility at Strategy Analytics, is for automakers to save on manufacturing costs.

To stay ahead of the curve, you’ll want to ensure that your car supports or can receive hardware upgrades to connect to 4G. As with smartphones, your best bet to stay in the know is by consulting with your local car dealer. While the modification may come in the form of downloadable software or physical spare parts, it will help to keep your vehicle up-to-date and functioning — especially during times of danger.
