Car manufacturers require reliable connectivity and cybersecurity solutions. Connectivity is provided by wireless modules that transmit and/or receive data, through specific high-speed and low latency transmission. The connected car can have its own digital identity thanks to an automotive-grade embedded SIM (eSIM) to identify itself on the network and verify the integrity of the data it transmits. The eSIMs also simplify logistics since the connectivity service providers can be activated after the vehicle has been manufactured or any time during its lifetime.
