Remote SIM provisioning (RSP) in IoT is made possible by eUICC technology, which is part of the eSIM standard. RSP enables the remote management of SIM profiles stored on eUICC-capable SIM cards. This includes over-the-air installation, switching, and deactivation of SIM profiles across different mobile network operators. Currently, there are two main RSP solutions: Machine-to-Machine (M2M) and Consumer solutions.
