eUICC stands for embedded Universal Integrated Circuit Card—a UICC with GSMA Remote SIM Provisioning (RSP) that enables multiple carrier profiles to be managed remotely.
eUICC is the secure hardware storing carrier profiles. eSIM is the complete system combining eUICC, profiles, provisioning infrastructure, and device software.
No, eUICC can be embedded (MFF2) or removable (2FF, 3FF, 4FF sizes). The defining feature is Remote SIM Provisioning capability, not physical form factor.
eUICC profile capacity varies by memory size, profile complexity, and device policy. There's no fixed industry number—it depends on specific device and vendor implementation.
SGP.22 is the GSMA consumer eSIM standard using QR codes and apps. SGP.32 is designed for IoT devices, enabling automated provisioning at scale without user interaction.
eIM (eSIM IoT Remote Manager) is a SGP.31/32 component enabling remote profile management for IoT fleets. It works with IPA to manage eSIMs without user interaction.
