What is remote sim provisioning and how to use it?

Imagine managing hundreds of connected devices spread across different countries, each needing a unique SIM card and activation process. Remote SIM Provisioning (RSP) has arrived, revolutionizing how we connect and manage devices in the ever-growing Cellular IoT (CIoT) landscape.

What is RSP? In essence, it’s the ability to remotely activate and manage a device’s SIM profile over the air, eliminating the need for physical SIM cards and manual interventions. This technology, enabled by GSMA’s Embedded SIM (eSIM) specification, uses secure communication protocols to deliver encrypted activation profiles directly to devices.


Why is RSP gaining traction in CIoT? The answer lies in its ability to address critical challenges faced in this sector:

  1. Simplified Deployment: Gone are the days of waiting for physical SIM cards and manually inserting them into devices. RSP allows mass deployment and remote activation, saving time and resources, especially for geographically dispersed setups.
  2. Enhanced Flexibility: RSP empowers dynamic switching between network providers based on coverage, cost, or data needs. This flexibility is crucial for devices operating in areas with fluctuating network availability or roaming across borders.
  3. Scalability and Cost Savings: Eliminating physical SIMs reduces manufacturing, logistics, and operational costs. Additionally, RSP simplifies device management, freeing up resources for innovation and growth.
  4. Security: Embedded SIMs reside securely within devices, minimizing the risk of physical tampering or loss compared to traditional SIM cards. Additionally, remote provisioning reduces the risk of interception during physical delivery.
  5. Future-Proofing: RSP leverages standardized protocols, ensuring compatibility with future network upgrades and device advancements, making CIoT deployments sustainable in the long run.


However, challenges remain. Security concerns surrounding remote provisioning and managing multiple profiles require robust measures. Additionally, integrating RSP with existing systems and processes demands collaboration between technology providers and operators.


Despite these hurdles, the benefits of RSP for CIoT are undeniable. This technology allows seamless connectivity and efficient device management, from remote asset tracking to smart city sensors. As adoption accelerates, RSP is poised to unlock the full potential of Cellular IoT, shaping a future where connected devices operate seamlessly, securely, and cost-effectively, regardless of their location.


How Remote SIM Provisioning Works? 

Remote SIM provisioning (RSP) is only possible with the magic of eUICC, which stands for Embedded Universal Integrated Circuit Chip. But what exactly is it, and how does it differ from the traditional SIM card?

This shift from physical to digital unlocks new levels of flexibility:

  • Effortless switching: Need to change carriers? With eUICC, selecting a new plan online is simply a matter—no more waiting for physical cards or fiddling with trays.
  • Global connectivity: Traveling abroad? Your eUICC can seamlessly switch to a local network, eliminating excessive roaming charges.
  • Dynamic updates: Carriers can push security patches, feature upgrades, and even new network configurations directly to your device, ensuring you’re always up-to-date.

Now, let’s differentiate between consumer eSIMs found in smartphones and M2M eSIMs used in IoT devices:

  • Consumer eSIMs: Designed for frequent user interactions, they focus on ease of use and intuitive interfaces for managing profiles and switching carriers.
  • M2M eSIMs: Primarily targeted at machine-to-machine communication, they prioritize stability, low power consumption, and long lifespans. Security measures are also enhanced to protect critical infrastructure and data.

While both leverage the same eUICC technology, their specific functionalities cater to distinct needs.


The future of connectivity hinges on this transformative technology. eUICC empowers consumers and businesses with incredible flexibility, security, and future-proofed scalability. As RSP and eUICC technology mature, we can expect even more exciting advancements, further blurring the lines between physical and digital worlds and ultimately shaping a genuinely seamless and connected future.


The Process of Remote SIM Provisioning

Imagine instantly activating a new network connection on your smart device without physically swapping a SIM card. eUICC, embedded within your device, makes this possible by enabling remote SIM profile changes.

  1. Initiation: The process begins with a request – perhaps you choose a new carrier plan within your device settings, or your IoT device sends a signal indicating a need for change.
  2. Authentication: Secure communication protocols handshake between your device and the relevant network operators, ensuring authorization and preventing unauthorized access.
  3. Downloading the New Profile: Once authenticated, your eUICC receives the encrypted new profile from the network, containing essential information like carrier configuration and security keys.
  4. Verification and Activation: The downloaded profile undergoes rigorous verification within the eUICC’s secure enclave to ensure its authenticity and validity. The new profile is activated upon successful verification, making your device instantly connected to the new network.
  5. Deactivation (Optional): The old profile can be automatically deactivated, freeing up space within the eUICC and ensuring a clean transition.

Throughout this journey, eUICC plays a pivotal role:

  • Secure Storage: It houses multiple profiles safely, isolating them from other data on your device.
  • Dynamic Switching: It facilitates seamless transitions between profiles, ensuring connectivity.
  • Over-the-Air Updates: It receives and verifies new profiles transmitted remotely, eliminating the need for physical interaction.

However, integrating M2M eUICC requires careful consideration of specific challenges:

  • Custom Integrations: Different carrier tools and protocols necessitate custom integrations, demanding collaboration between device manufacturers, MNOs, and platform providers.
  • Standardization Challenges: While progress is being made, complete standardization across all network technologies is still evolving, requiring adaptability within the integration process.
  • Security Concerns: Securing remote communication and profile management requires robust security protocols and vigilance against potential vulnerabilities.
