Executive Summary

The SIM provides secure access to mobile networks

The SIM (Subscriber Identity Module) is an application which runs on the UICC (Universal Integrated Circuit Card) to provide secure, identifiable and authenticated access to mobile networks. It securely stores international mobile subscriber identity (IMSI) number and its related key, which are used to identify and authenticate subscribers.

Remote SIM Provisioning is being introduced

The eUICC (Embedded UICC) is an UICC which enables secure remote and/or local management of operator profiles, regardless of its form factor. The eUICC form factor may be either soldered (e.g. MFF2) or removable (e.g. 3FF or 4FF).

RSP (Remote SIM Provisioning) is a solution which enables remote provisioning of one or more operator profiles into the eUICC. An operator profile plays the role of a single UICC which contains SIM, USIM, ISIM, or CSIM applications. An operator profile can be installed, enabled, disabled, and deleted from the eUICC. While it is possible to install more than one profile, only one profile can be enabled at a given time. When a profile is enabled, the eUICC behaves as a normal UICC over the Terminal – UICC interface, therefore even a legacy device can use the eUICC when attaching to a mobile network.

The industry is working towards one RSP solution for the consumer market

Following recent developments regarding Embedded SIMs for M2M functions, the industry is working towards one Remote SIM Provisioning solution for the consumer market which will be interoperable between different suppliers and compatible with the existing M2M solution.

Samsung is an active participant in GSMA’s Remote SIM Provisioning standardization efforts. As a result, it was unveiled in February, 2016 that Samsung’s Gear S2 3G smart watch would adopt GSMA's Remote SIM Provisioning Technical Specification Phase 1, SGP.22 V1.0, which was published concurrently.
