Thanks to these systems, drivers experience a much safer and more comfortable driving experience.

For example;

Before leaving home in the morning, you can turn on your vehicle's air conditioning from your phone, check the battery level, or view your vehicle's location.

The technology working behind all of this is the eSIM connection.

How Does eSIM Work in Vehicles?

The basic working logic is actually similar to smartphones.

The communication module inside the vehicle connects to the mobile operator network and provides internet access.

Thanks to this connection, the vehicle can access;

• Manufacturer servers,
• Map services,
• Emergency centers,
• Multimedia platforms

In modern vehicles, this system usually works with 4G LTE or 5G infrastructure.

Especially in new generation BMW, Mercedes, and Audi models, 5G supported connections are used.

Two Different eSIM Types Used in Vehicles

eSIM systems used in vehicles are often confused.

In fact, there are two different structures.

1. Telematics eSIM

This system is found in almost all new vehicles.

It is managed by the vehicle manufacturer.

The user cannot intervene.

The purpose is to perform operations such as:

• Emergency calls
• Vehicle diagnostics
• Service connections
• Remote vehicle management

For example, when an accident occurs, the eCall system is activated and the vehicle can automatically send a call for help.

This process takes place over the telematics eSIM.

2. Personal eSIM

Personal eSIM is a much more advanced system.

Thanks to this feature, the user can define their own data plan directly to the vehicle.

Thus, the vehicle:

• Gains independent internet access,
• Can create a Wi-Fi hotspot,
• Can provide internet to passengers,
• Can use multimedia services.

Personal eSIM has become widespread especially in BMW's new generation models.

Audi and Mercedes-Benz have also been transitioning to this technology in recent years.

Why is Personal eSIM Important?

Many users ask this question:

"Why should I use eSIM in the car when my phone has a hotspot feature?"

There are several important reasons for this.

Stronger Signal

Vehicles usually have high-performance antennas placed on the roof.

These antennas can receive a much stronger signal compared to phones.

It provides significant advantages especially in:

• Rural areas,
• Mountainous areas,
• Long distance drives,

Protects Phone Battery

Hotspot usage drains the phone battery quite quickly.

Thanks to Personal eSIM, the internet connection is provided directly through the vehicle.

This allows the phone to be used for a longer time.

More Stable Connection

In phone hotspot connections, you may see:

• Disconnections,
• Reconnections,
• Performance drops

In-car eSIM connections, on the other hand, work much more stably.

Better Experience for Passengers

All passengers inside the vehicle can use the same connection.

In this way, the following can connect to the internet at the same time:

• Tablets,
• Laptops,
• Gaming consoles,
• Smartphones

This provides a great advantage, especially on long journeys.
