eSIM has already become an integral part of the mobile world. More and more people are replacing the physical SIM card with a digital chip that is embedded directly in the device, without the need for a removable card. After this technology conquered the world of smartphones, it is now beginning to enter other fields as well – one of the most prominent and intriguing being the automotive industry.
But what does eSIM in cars actually mean? How does it work, and why should it matter to us as consumers?

What is eSIM and How Does It Integrate into Cars
An eSIM is a small chip embedded directly inside the device – whether it’s a mobile phone, a smartwatch, or in our case, the car’s system. The chip connects to a cellular network and enables access to the internet and various digital services. The main advantage is that there’s no need to insert a physical card or replace it when switching providers or updating a plan – everything is done remotely, through software.
In a car, this means that the manufacturer or the driver can connect the vehicle to a cellular network immediately upon leaving the factory or at the time of purchase. Instead of relying on a mobile phone connected via Bluetooth or a physical cable, the car has its own independent network connection, opening up a range of new possibilities.
eSIM for Cars: Key Advantages
First, eSIM allows the car to stay constantly connected. The permanent network connection provides access to advanced navigation services with real-time traffic updates, downloading new maps, and integration with other smart systems. Instead of relying on an external device, everything is built directly into the car’s system.
Another advantage is remote management. Car manufacturers and leasing companies can monitor the vehicle’s condition, schedule maintenance, and perform software updates over the air (OTA). In other words, instead of visiting the garage to update the multimedia system or the central computer, the update is downloaded directly via the cellular connection. This saves both the manufacturer and the driver time and money.
From a safety perspective, there’s also a major benefit. In the event of an accident, the car’s system can automatically send an emergency call along with the exact location, without depending on the driver’s mobile phone. Such services already exist today in some of the latest models, especially in Europe, and are becoming increasingly common.

Practical Uses of eSIM in Cars
The most common use is internet connectivity for navigation and multimedia systems. For example, a driver can enjoy streaming music or podcasts directly from the car’s system without needing to connect their phone.
Another use is in maintenance and monitoring. Cars are equipped with more and more sensors, and they can send real-time data to the manufacturer or the garage: engine status, battery health (in electric cars), safety systems, and more. This information helps identify issues before they become serious problems.
In addition, eSIM enables car sharing services. Companies operating fleets of vehicles can control car locking and unlocking, track usage, and manage pricing — all through the cellular connection. This makes it possible to run smart rental systems without the need for a physical key or external card.
Impact on the Automotive Market
More and more manufacturers are equipping their new models with built-in eSIMs. Some even offer data packages as part of the purchase, so the customer gets a “connected” car from day one. Other manufacturers allow drivers to choose a local telecom provider depending on the country where the car is located, all managed digitally through the car’s menu system.
At the same time, telecom companies are also recognizing the potential and are offering data plans tailored specifically for vehicles. These packages are designed differently from mobile phone plans, with an emphasis on continuous and stable connectivity.
Leading Car Manufacturers in the eSIM World
The two most prominent manufacturers that have integrated eSIM technology into their vehicles are BMW and Tesla, each with a slightly different approach.
BMW was among the first to embed eSIM into its car systems, in its latest models based on the BMW OS 8 operating system and above. The service, called Personal eSIM, allows drivers to connect the car directly to a cellular network without relying on a phone. Drivers can provide Wi-Fi for passengers, stream music or video, use navigation with live traffic updates, and also receive over-the-air (OTA) software updates. In addition, using eSIM in BMW vehicles offers convenience: drivers can add or change a cellular provider through the app or directly via the car’s multimedia system, without needing a physical SIM card.
Tesla, on the other hand, designed the entire driving experience around full internet connectivity, with eSIM as an integral part of the system. Every Tesla vehicle comes with a built-in cellular connection that enables continuous software updates, online maps and navigation, access to built-in apps like Spotify or Netflix, and remote control through the Tesla smartphone app. Tesla’s main advantage lies in integration: drivers rarely need to deal with settings, since connectivity is built-in and managed directly by the company. In markets where needed, Tesla allows customers to upgrade to a Premium Connectivity package for broader data use, but the foundation is always the embedded eSIM.
Audi is one of the leading car manufacturers that adopted eSIM technology early on as part of its Audi connect services. Many Audi models feature a permanently installed eSIM (Embedded SIM) that enables independent cellular connectivity for the vehicle, without the need for a physical SIM card or the driver’s smartphone.
Porsche integrates eSIM technology into its newer models as part of the Porsche Connect service ecosystem, designed to make the vehicle fully connected and independent in terms of cellular communication. The eSIM is embedded directly into the vehicle’s system, providing a constant network connection without relying on the driver’s phone or a physical SIM card.
eSIM for Cars: Looking Ahead
As cars become smarter and more connected, the role of eSIM will continue to grow. In the near future, autonomous driving systems will require stable network connections to receive traffic updates, data from external sensors, and to share information with other vehicles on the road.
Driver experience is also expected to improve, from advanced entertainment systems and personal concierge services to automatic payments for parking and fuel directly through the car’s system. All of this will be possible thanks to the seamless connectivity provided by eSIM.
Frequently Asked Questions
Do all cars support eSIM technology?
No. eSIM is available in specific models, mainly in more advanced vehicles, particularly from premium manufacturers and in electric cars. However, the technology is constantly evolving, so it is worth keeping up with the latest developments.
Does the driver need to purchase a special data plan for the car?
It depends on the manufacturer and the model. Some manufacturers include a basic data plan as part of the vehicle package, while in other cases it is possible to purchase a dedicated data plan or upgrade to a more advanced service.
Is it possible to choose a cellular provider for a car with eSIM?
In some models, yes. Advanced eSIM systems allow drivers to select or change a mobile network provider digitally through the car’s system or a dedicated app.
