The Remote SIM Provisioning (RSP) is a server driven solution to provision and remotely manage operator profiles on the eUICC.

The RSP is comprised of two elements:

• SM-DP (Subscription Manager-Data Preparation) stores and manages the network profiles
• SM-SR stands for Subscription Manager Secure Routing. This entity securely delivers the encrypted operator credentials to the SIM and then, once the credentials are installed, remotely manages the SIM thereafter (enable, disable and delete the credentials as necessary during the product’s lifetime).

Access to the SM-SR is critical to enable seamless network switching. Without it, localising or switching networks over-the air (OTA) can cause complications and delay
