Connected cars - vehicle connectivity with eSIM technology

Connected cars with smart and secure connectivity

The future of the automobile is, ironically, not the car itself. The car of tomorrow will work more like a smart device on wheels. Connected cars and autonomous driving are taking on new meaning. Private and shared vehicles alike need to provide the flexibility of allowing users to personalize in-car interactions. 5G and autonomous vehicles will transform the driving experience into one that is safer, more comfortable, and more convenient. Cars in the near future will connect and exchange data with other vehicles, infrastructure and consumer devices. Our solutions play a decisive role. Security will be at the heart of this digital transformation, ensuring that the connected vehicles of tomorrow provide safe, reliable connections and personalized services for drivers and passengers. To continue to fascinate loyal users and attract new customers, cars and vehicles will depend on meticulously secured connectivity.

Vehicle connectivity with eSIM

The driving force behind the success of the connected car is embedded SIM – or eSIM – technology. eSIM is gaining ground in more and more applications. Devices and machines that require a mobile connection can be equipped with permanently installed SIM chips. As the market leader in this technology, we support you in securing the communication your vehicles need.

We are setting the standards for vehicle SIM modules, ensuring that in the connected car risk is minimized and opportunities are maximized. Our vehicle SIM modules are tamper proof and provide a robust, secure platform for connectivity during the entire lifetime of a vehicle. Auto manufacturers can safely manage millions of connected cars with no worries – and they are also free to choose the Mobile Network Operator (MNO) partners they want to work with. Our production complies with the highest industry standards and certifications, such as IATF 16949 specifications.

Our solutions:

  • Carry eCall and ERA-GLONASS approvals and certifications
  • Include the eSIM Management solution, with SLA excellence and high-performance, high-traffic capability
  • Offer 5G connectivity
  • Comply with Digital Car Key (DCK) guidelines set down by the Car Connectivity Consortium (Bluetooth Low Energy and NFC)

From car to mobile smart device

Always on. Isn’t this the motto of our times? It’s what drivers and passengers expect today – nothing less. This simple assumption has far-reaching implications. Infotainment services and security features need permanent and secure connections that carmakers and their customers can rely on at all times.


Connected vehicles come with factory-embedded SIMs. Up to now, however, consumers haven’t been able to use these connections for personal use without incurring additional costs. In the future, connected cars will come with independent eSIMs – one for the car and one for the driver. The second embedded SIM allows consumers to use their private data plans while they’re in the car. The car, in essence, turns into a connected mobile device and becomes a part of the consumer’s regular cellular data use.

Our Dual SIM Dual Active solutions provide seamless connectivity. The eSIM automatically activates when the driver enters the car and deactivates when they exit. No hassle and no more fumbling with Bluetooth pairing. Consumers can continue using mobile services – such as music streaming that they regularly enjoy. An added benefit is that the eSIM functionality is not limited to one person and allows to manage eSIMs of different users. Family members and other passengers can access the on-board entertainment system or watch a video on their smartphones.

Global connected car services, in line with telco regulations

The concept of the connected vehicle is not just about better infotainment and improved navigation systems. With our eSIM Management’s standardized connectivity management service, you can control millions of connected cars efficiently. It is easy to manage a large fleet of vehicles for yourself or your customers with scalability and speed.

We give you a competitive edge. Our hardware-based eSIMs are embedded during production. So vehicles built by any carmaker can be connected to a mobile network the moment they leave the factory. Secure over-the-air remote provisioning and remote subscription management is enabled with eSIMs.

This brings enormous benefits to enterprises with large fleets – for example because entire fleets can be connected to a carrier in one go. This saves time and money, and helps reduce the total cost of ownership. Looking to streamline operations by simplifying logistics? Remote management capabilities remove the need for regular, time-intensive software SIM updates. Need highly reliable global scalability? With our eSIMs, automotive manufacturers can automatically switch to the optimal carrier profile. This makes it easy for OEMs to meet local requirements while remaining compliant with in-country regulations – such as bans on permanent roaming for imported vehicles in Brazil, or guidelines to route automated accident alerts over the domestic network as stipulated in Russia’s ERA-GLONASS system

eSIM and the Connected Car

Connected cars, where driving operations and in-vehicle services are enhanced and delivered by network connectivity, are in a period of unprecedented growth. Strategy Analytics predict that approximately half a billion connected cars will be on the road by 2023.

Without connectivity management, mobility has no future

The global automotive industry is undergoing a significant transformation. And it’s not simply technological. Demographic, regulatory, and environmental pressures make change inevitable. Staying connected is becoming status quo. The connected vehicles of tomorrow must provide secure connectivity, reliable communication, personalized services and safety for drivers and passengers.
