Key Insights

Remote SIM provisioning, or RSP, is a proven approach for managing secure device identity through embedded SIMs (eSIMs) and integrated SIMs (iSIMs) across different mobile network operators.

Remote SIM provisioning has become increasingly popular thanks to embedded universal integrated circuit card (eUICC) technology, an integral part of the embedded SIM (eSIM) standard. Although people often confuse eUICC with eSIM, it’s worth noting that an eUICC is a SIM component that empowers carriers to add a new SIM profile. This means that with an eUICC, you can switch between carriers without the hassle of swapping SIM cards.
RSP offers a secure, robust and highly scalable solution for addressing the traditional SIM challenges. It allows device owners to change network operators remotely by securely switching operator profiles over the air. This remote profile management removes the need for physical access. IoT devices benefit from existing SIM functionality, but all wrapped up in new, smaller and more reliable SIM form factors such as the eSIM and iSIM.
RSP and eSIM technology are huge breakthroughs, relieving a major bottleneck in at-scale device deployment for IoT. A growing ecosystem is discovering RSP benefits for more use cases. Ample innovation opportunities exist for established firms and startups who can build on the proven value of RSP solutions.
The core function of RSP is to enable remote management of profiles with operator and subscriber data on devices.
