RSP remote SIM provisioning

Last updated on 

Remote SIM Provisioning (RSP) is a technology that enables the over-the-air (OTA) provisioning of SIM cards in mobile devices without the need for physical access to the SIM card. It allows mobile network operators (MNOs) to remotely manage and provision SIM cards, reducing the need for manual SIM card replacements and improving the flexibility and efficiency of mobile services.

Here is a detailed explanation of the RSP process:

  1. SIM Card Profile Creation: The first step in RSP is the creation of SIM card profiles. A SIM card profile contains the necessary information to identify and provision a SIM card, such as the International Mobile Subscriber Identity (IMSI), authentication keys, and network settings. MNOs create and store these profiles securely in their back-end systems.
  2. Device Manufacturer Integration: Device manufacturers integrate RSP capabilities into their devices during the manufacturing process. This integration involves embedding a secure element or eUICC (embedded Universal Integrated Circuit Card) into the device. The eUICC is a chip that can store multiple SIM profiles and can be remotely managed.
  3. Subscription Management Secure Domain (SM-SD): The eUICC contains a secure domain called the Subscription Management Secure Domain (SM-SD). The SM-SD ensures the security and integrity of the SIM card profiles stored on the eUICC. It manages the authentication and encryption processes between the eUICC and the MNO's servers.
  4. MNO Connectivity: The MNO establishes a secure connection with the eUICC in the device over a cellular network or an internet connection. This connection allows the MNO to communicate with the eUICC and remotely manage SIM card profiles.
  5. Remote SIM Provisioning: Once the connection is established, the MNO can remotely provision SIM card profiles onto the eUICC. The MNO sends the necessary SIM card profile to the device, and the eUICC securely stores it in the SM-SD.
  6. Profile Activation: After the SIM card profile is provisioned onto the eUICC, the MNO activates the profile to make it operational. Activation involves associating the SIM card profile with a specific mobile network subscription and enabling the necessary services, such as voice, data, and messaging.
  7. Profile Switching: One of the significant advantages of RSP is the ability to switch between different SIM card profiles without physically replacing the SIM card. Users can switch profiles based on their preferences or to access different mobile networks when traveling internationally. Profile switching is performed remotely by the MNO, and the new profile is downloaded and activated on the eUICC.
  8. Security and Authentication: RSP employs robust security measures to protect the SIM card profiles and ensure secure communication between the eUICC and the MNO's servers. These measures include encryption, digital signatures, and mutual authentication between the eUICC and the MNO's systems.
  9. OTA Updates: RSP also allows MNOs to remotely update SIM card profiles over-the-air. This capability enables the MNO to update authentication keys, network settings, and other parameters without physically accessing the SIM card. OTA updates enhance security and enable the deployment of new services and features.

Overall, RSP revolutionizes SIM card management by eliminating the need for physical SIM card replacements and enabling remote provisioning and management. It offers flexibility, convenience, and enhanced security for both mobile network operators and end-users.
