eSIM Standardization Efforts

The GSMA Association and the eSIM
The GSM Association is a trade body that represents the interests of mobile network operators worldwide. Approximately 800 mobile operators are full GSMA members and a further 300 companies in the broader mobile ecosystem are associate members.  Starting 2014, GSMA had begun to work on an ecosystem related to embedded SIM (eSIM), or eUICC, to address mobile networks and market needs for connecting non-consumer, also referred to as M2M, devices to mobile networks for all sort of B2B applications, such as meter reading, connected cars, intelligent remote controlling, among others.

The Remote SIM Provisioning Initiative
It first came up with the Remote SIM Provisioning initiative and formed several working groups. The working groups focused on standardizing a suite of specifications to ensure the whole ecosystem, including eSIM vendors, device manufactures, mobile operators, and other related service providers, follow the same standards and unified framework for all related processes. This has helped the mobile industry to address more than 10 billion devices connecting to mobile networks by 2020, as predicted. By February 2016, the complete version of specifications were released. Since December 2015, it also has begun to work on similar specifications targeting consumer devices.

The Three Major Working Groups
There are three major working groups working the specifications. One group is called the RSP Task Force (RSPTF), consisting of major mobile operators and works on specifications served as requirements for both M2M and consumer devices. The RSPTF group has more than twenty major mobile operators actively contributing to the requirements. The specifications produced from RSPTF are SGP.01 and SGP.21.

Another group, called the RSP Technical (RSPTEC), is working on implementation specification based on the requirement specifications from RSPTF. RSPTEC is composed of eSIM vendors, OEMs, and all related service providers. iBasis is an active member of this group.

Finally, the third main group, called “RSP Certification and Compliance” (RSPCERT), is working on Security Accreditation Scheme, Test, and Profile Protection specifications.

For those of interested in the detail of all the specifications, the full array of documents can be found on the GSMA Public Website.
