2. Ensure the device is connected to a network with regional coverage.
3. Allow the eSIM to automatically switch networks as needed for optimal connectivity.

Real-Time Data Access and Remote Management:
For real-time data access and remote management, utilize the following guidelines:

1. Access the designated application or platform provided by the OEM.
2. Monitor key metrics such as vehicle status, EV charging, and location.
3. Utilize remote features like in-car payments for services such as parking and refueling.

Proactive Maintenance with OTA Updates:
To benefit from proactive maintenance and OTA updates, adhere to the following process:

1. Enable automatic OTA updates on the automotive IoT device.
2. Receive real-time vehicle status checks and safety alerts to prevent downtime and accidents.
3. Ensure the device is always connected to leverage the latest features and enhancements.

eSIMs:

• The secret to unlocking cross-border IoT for automotive OEMs
• IoT spending in the Asia-Pacific (APAC) region is rapidly growing – it’s projected to reach USD435 billion in 2027.1
• This growth is fueling innovations in connected vehicles (CVs) and fleet management.
• Network fragmentation can disrupt the successful rollout of CVs. With the right IoT connectivity strategy, US and Europe-based original equipment manufacturers (OEMs) can navigate these challenges and scale automotive IoT across  APAC.

How OEMs are leveraging automotive IoT

• BMW taps into digital services by enabling in-car payments for traffic updates and entertainment subscriptions. This creates new revenue streams while offering drivers a seamless, connected experience
• Mercedes-Benz boosts ownership by offering real-time data access and remote vehicle management through its application programming interfaces (APIs). Drivers can monitor key metrics and control features like EV charging and location via a smartphone, while also using in-car payments for services like parking and refuelling.
• Volvo uses
  over-the-air (OTA) updates for proactive maintenance, offering real-time vehicle status checks and safety alerts. This helps reduce downtime, prevent accidents, and cut maintenance costs, ensuring vehicles stay safe and efficient.

eSIMs remove cross-border IoT deployment challenges for OEMs, unlocking software-based operations across APAC. Here’s how:

• No need for manual SIM swaps.
• Regional connectivity is always on.
• Automotive IoT devices operate beyond borders while enabling proactive  maintenance
• eSIMs switch to the local network automatically. No need to manually deploy in every location.

How BYD uses IoT for fleet optimisation

• BYD enhances fleet efficiency using IoT for GPS tracking, vehicle monitoring, and video telematics,  providing real-time data to optimise routes, energy use, and driver behaviour across borders. In 2024, it surpassed its target sales of 4 million new EVs, matching Ford and Honda.5
• Thanks to its IoT-powered fleet management, BYD is now a market leader in Southeast Asia:
  • Sold over 417,000 new EVs outside of China in 20246
  • Ranked first in Indonesia’s top 10 best-selling EV brands7
  • Partnered with Grab in 2025 to deploy up to 50,000 EVs in Singapore, Malaysia, Indonesia, the Philippines, Thailand, and Vietnam
  • Quadrupled sales in Singapore in 2024 compared to the previous year, becoming Singapore’s most popular car brand in 2024, unseating Toyota
  • With Singtel’s eSIM technology, BYD ensures seamless connectivity across  APAC, keeping vehicles and driver systems running smoothly wherever they go.
