eSIM / eUICC
eSIM is now standard in smartphones (iPhone XR+, Android flagships), laptops, and cellular IoT modules. Understanding SGP.22 RSP is essential for telecom apps that provision cellular connectivity programmatically.
What It Defines
The embedded SIM specifications define a remotely programmable SIM soldered to a device. SGP.02 covers M2M eSIM (OTA profile management via SM-SR/SM-DP for industrial IoT). SGP.22 covers consumer eSIM (LPA on-device, RSP platform for over-the-air profile download and switching between operators).
