What is eSim?
The ubiquitous SIM card has played a fundamental role in mobile telecommunications for over 25 years. It is recognised by end users and provides a secure means for authenticating devices onto networks, all inside a removable “Secure Element”, which is easily transferrable between mobile devices.
Although the role of the SIM itself is not changing, the GSMA has defined a radical new way to load it into devices. Now the SIM may be securely downloaded into a ‘Secure Element’ that can be permanently embedded inside any type of device. To enable this change, an ecosystem of trusted platforms and players has been facilitated by the GSMA to create the eSIM solution. It offers an equivalent level of security and protection to that provided by the removable SIM card.
What is eSIM for Consumer?
eSIM is a global specification by the GSMA which enables remote SIM provisioning of any mobile device.
eSIM now allows consumers to store multiple operator profiles on a device simultaneously, and switch between them remotely, though only one can be used at a time.
eSIM for M2M
The GSMA’s Embedded SIM Specification provides a single, de-facto standard mechanism for the remote provisioning and management of machine to machine (M2M) connections, allowing the “over the air” provisioning of an initial operator subscription, and the subsequent change of subscription from one operator to another. GSMA Embedded SIM is a vital enabler for Machine to Machine (M2M) connections including the simple and seamless mobile connection of all types of connected machines.
eSIM for IoT
The eSIM IoT specification is designed to be used in IoT devices that are network-constrained or user interface constrained. This specification is based on the Consumer eSIM specification with a few notable differences.
eSIM Architecture
Since eSIM technology was first proposed by the GSMA, three different architectures for eSIM technology have been developed. In this video, learn about the three eSIM architectures, and how they can be applied in real life scenarios.
The eSIM White Paper
The eSIM White Paper provides both a primer to introduce the basics of Remote SIM Provisioning technology and an introduction to the detailed technical specifications for both the consumer solution & M2M solution channels:
