Beyond Smartphones: eSIM in Automotive and Drones

When most people think of eSIM (embedded SIM) technology, smartphones come to mind first. After all, the shift from physical SIM cards to digital profiles has been most visible in flagship phones like the iPhone and Google Pixel. But eSIM isn’t just about making it easier to switch mobile plans on your handset. From connected cars to high-flying drones, eSIM is quietly transforming how a variety of devices get online—without ever popping in a tiny piece of plastic.

In this article, we’ll explore how eSIM is reshaping connectivity in the automotive world, and how it’s enabling drones to roam the skies with constant data access. We’ll also look at why this technology matters for businesses, travellers, and even everyday consumers who might soon find themselves surrounded by a fleet of connected gadgets. By the end, you’ll see that eSIM is much more than a smartphone convenience; it’s a foundational technology for the next generation of IoT devices.

1. The Rise of Connected Vehicles

Modern cars are no longer just mechanical marvels; they’re also rolling computers, packed with sensors, infotainment systems, and advanced telematics. To power all these features—whether it’s real-time traffic updates, over-the-air software updates, or in-car Wi-Fi—automakers have traditionally used physical SIM cards. But that approach can be cumbersome and limits flexibility.

Enter eSIM. By embedding a programmable chip directly into the car’s telematics module, manufacturers can enable connectivity from the moment the vehicle rolls off the assembly line. And because the SIM is digital, the car’s data plan can be updated or switched remotely, without requiring a trip to the dealership to swap out a physical SIM card.

1.1 Benefits for Automakers and Drivers

Seamless Updates: With eSIM, carmakers can push software patches and feature upgrades directly to vehicles. This helps keep infotainment systems and safety features current, all without physical interventions.
Global Roaming: If you’re driving across borders—say, from France to Spain—the car can automatically switch to a local data plan for better coverage or lower costs.
Reduced Logistics: Automakers can ship the same eSIM-equipped model worldwide, then provision local carrier profiles digitally, cutting down on the need to produce region-specific hardware.
Enhanced Security: Physical SIMs can be lost or tampered with, while eSIM typically includes robust digital authentication methods. That makes it harder for bad actors to hijack a car’s connectivity.

The result is a more flexible, secure, and efficient system for keeping cars connected. From real-time navigation to in-car streaming services, eSIM helps ensure your vehicle is always online—no matter where the road takes you.

2. eSIM and Drones: Taking Connectivity to New Heights

Drones, too, are evolving rapidly. What began as hobbyist quadcopters buzzing around parks has morphed into a wide array of commercial and industrial applications—package deliveries, aerial surveys, agriculture, and even search-and-rescue missions. In many of these use cases, real-time data transfer is crucial. But relying solely on short-range radio links (like Wi-Fi) can be limiting, especially when drones need to operate over long distances or in urban environments.

By integrating eSIM, drones can tap into cellular networks just like a smartphone. This unlocks a host of possibilities:

2.1 Real-Time Video and Telemetry

With eSIM-enabled drones, operators can stream live HD video back to a control center, no matter how far the drone roams—assuming there’s cellular coverage. This is invaluable for emergency services or inspection tasks where on-the-spot decision-making is essential.

2.2 Over-the-Air Updates and Mission Changes

Just like connected cars, drones can receive firmware updates and new flight instructions remotely. If a mission profile changes—say, a new search grid for a missing person—the operator can push the update via the drone’s cellular link, eliminating the need for a physical connection or manual SIM swap.

2.3 Multi-Carrier Flexibility

A drone operator might find that one carrier has better coverage in rural areas, while another is superior in dense city centers. With eSIM, switching carriers can be as simple as downloading a new profile. This flexibility is key for businesses that operate fleets of drones across different regions.

3. The Internet of Things (IoT) Angle

Both connected cars and drones fall under the broader umbrella of the Internet of Things (IoT). As IoT devices proliferate—think everything from smartwatches and industrial sensors to automated robots—eSIM offers a streamlined way to manage connectivity at scale.

Instead of maintaining an inventory of physical SIMs for every device in your fleet, you can manage all your eSIM profiles from a central dashboard. This is particularly beneficial for large enterprises or service providers:

Centralized Provisioning: Deploy hundreds of devices (cars, drones, or sensors) and assign carrier plans remotely, without physically touching each device.
Data Usage Tracking: Monitor usage across all devices, spot anomalies, and optimize costs by switching plans when necessary.
Scalability: As your fleet grows, you don’t need to worry about stocking physical SIM cards or shipping them around the world. Everything happens digitally.

4. Travel and Cross-Border Use Cases

Let’s say you’re a logistics company running a fleet of connected vans that traverse France, Germany, and Spain. Or perhaps you’re a drone delivery service aiming to cover multiple regions in the United States. eSIM can significantly reduce roaming costs by automatically switching to local carrier profiles, similar to how travellers use eSIM on smartphones.

You might even consider specialized providers like Simplysim that offer data plans for multiple destinations. This way, your vehicles or drones can cross borders and pick up local coverage without missing a beat. It’s essentially the same concept that smartphone travellers love—only scaled up to entire fleets of devices.

5. Security and Regulatory Considerations

While eSIM adds convenience, it also raises questions about security and regulatory compliance—especially in industries like automotive and aviation (including drones). Authorities often require strict controls over how devices connect to networks, especially when they’re capable of crossing borders or flying over sensitive areas.

Fortunately, eSIM generally adheres to GSMA security standards, which mandate encryption and authentication protocols. Manufacturers and service providers can also implement additional safeguards, such as:

Secure Bootloaders: Ensuring that only authorized firmware updates can be installed.
Encrypted Communication: Protecting data in transit, whether it’s telemetry from a drone or location data from a car.
Remote Lock or Wipe: In case a vehicle or drone is stolen or goes rogue, operators can disable connectivity remotely.

On the regulatory side, some countries may have rules about which carriers or frequencies can be used, especially for drones. eSIM’s flexibility can help here too—devices can download compliant profiles for each region they operate in, as long as they adhere to local licensing and flight regulations.

6. Impact on Maintenance and Lifecycle Management

Both cars and drones have maintenance cycles that can span years. Physical SIMs might degrade or become outdated as carriers upgrade their networks (e.g., from 4G to 5G). With eSIM, manufacturers can push updates that enable newer network standards without replacing hardware. This can extend the lifespan of the device and reduce e-waste.

For instance, a connected car sold today might run on 4G networks. If the automaker later adds 5G support via an over-the-air update (assuming the hardware is compatible), the car’s eSIM profile can be re-provisioned to take advantage of faster speeds—no physical SIM swap required. This kind of future-proofing can save consumers money and keep vehicles relevant longer.

7. The Role of 5G and Edge Computing

As 5G networks roll out globally, eSIM-equipped cars and drones stand to benefit significantly. 5G’s low latency and high bandwidth can support advanced applications like:

Autonomous Driving: Self-driving cars rely on split-second decision-making. 5G can provide the real-time data flow they need, and eSIM ensures a stable connection wherever they roam.
Real-Time Drone Coordination: Fleets of drones could coordinate in the sky, sharing data on flight paths, obstacles, and weather conditions, all via 5G. eSIM allows each drone to maintain its own robust connection without manual SIM swaps.
Edge Computing Integration: Devices can offload heavy computations (like AI-driven image recognition) to edge servers on the 5G network. eSIM’s seamless connectivity means no downtime or coverage gaps.

This synergy between eSIM and 5G could reshape entire industries, from logistics and public safety to smart cities and beyond.

8. Challenges and Potential Pitfalls

While eSIM offers a host of benefits for automotive and drone applications, it’s not without challenges:

Carrier Fragmentation: Not all carriers worldwide have fully embraced eSIM, which can create coverage gaps or higher costs in certain regions.
Regulatory Hurdles: Drone operations especially may face strict rules about network usage and flight corridors, requiring careful compliance with local laws.
Security Risks: Embedded connectivity also means a bigger attack surface. Hackers could theoretically target cars or drones if security protocols are weak, though eSIM’s digital safeguards mitigate some risks.
Complex Setup for Consumers: For personal drones or specialized vehicles, users might find eSIM setup daunting if they’re not tech-savvy—though user-friendly apps can ease this pain.

9. Real-World Examples

A few pioneers are already showcasing how eSIM can revolutionise automotive and drone operations:
