Understanding the End-to-End Flow of SMDP+ eSIM Provisioning :
As eSIM technology continues to transform mobile connectivity, the SMDP+ (Subscription Manager Data Preparation+) platform by GSMA enables secure and scalable remote SIM provisioning. Please find below Q & A and end to end call flow :
-
Q: How does SMDP+ enhance connectivity for connected cars?
- A: SMDP+ enables seamless eSIM provisioning and management in connected vehicles, allowing OEMs and service providers to remotely and securely update network credentials across an entire fleet. This is essential for connected cars, which rely on continuous, reliable network connectivity for real-time data, telematics, navigation, remote diagnostics, and infotainment. By using SMDP+, vehicles can switch network providers as needed, ensuring the best available connectivity in different geographic areas, even across borders.
-
Q: What specific security measures does SMDP+ offer to protect connected car data and connectivity?
-
A: SMDP+ incorporates multiple layers of security that are crucial for connected cars, where protecting data and ensuring uninterrupted connectivity are paramount. Some key security measures include:
-
Strong Encryption: SMDP+ uses TLS (Transport Layer Security) for data in transit and asymmetric encryption for profile data, ensuring that only the intended eUICC (embedded Universal Integrated Circuit Card) on the car’s eSIM module can decrypt and install the profile.
-
Device Authentication: Before provisioning a profile, SMDP+ and SM-SR (Subscription Manager Secure Routing) authenticate the vehicle’s eUICC to ensure that only authorized devices can download and activate profiles. This helps prevent unauthorized devices from intercepting or tampering with eSIM profiles.
-
Remote Profile Management: Through SMDP+, profiles can be activated, deactivated, or switched remotely, allowing for immediate response to potential security incidents. This flexibility ensures that connectivity can be managed dynamically to counter threats without physically accessing the vehicle.

Q: What future advancements in connected car technology might leverage SMDP+ capabilities?
-
A: Future connected car features that could benefit from SMDP+ include:
-
Autonomous Vehicle Communications: With the rise of autonomous driving, vehicles will require high-speed, low-latency connections across regions. SMDP+ allows for quick network switching and provisioning, ensuring reliable connectivity essential for autonomous decision-making and safety.
-
Vehicle-to-Everything (V2X) Communication: Connected cars are moving toward Vehicle-to-Everything (V2X) technology, where cars communicate with infrastructure, other vehicles, and pedestrians. SMDP+ can dynamically manage network profiles for V2X applications, optimizing connectivity for real-time safety alerts, traffic management, and smart city integration.
