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.
The change from the Removable SIM to an eSIM provides benefits for many players:
For everyone,
eSIM provides an equivalent level of security as the removable SIM card. This is vital as it is the subscription credentials stored on the SIM card that enable secure and private access to mobile networks. It also supports the integrity of the billing process, especially in roaming scenarios:
For the device end user, eSIM enables simplified management of subscriptions and connections. End users will no longer have to manage several SIM cards:
For organisations,
eSIM enables remote management of subscriptions. This is a significant benefit where devices are not managed by the end user or are not be readily accessible (for example due to operational scale, making individual device management cost prohibitive). This enables pioneering categories of connected devices:
For distributors,
simplified logistics are possible, customisation for specific operators or regions may be reduced:
Operators
will have simpler means to expand their businesses into emerging markets, for example, automotive, wearables and consumer electronics. SIM card distribution costs will be eliminated, and eSIMs will enable new distribution models for devices and for marketing of subscriptions:
Device Manufacturers,
can exploit the reduced space within their products to make smaller devices. Their products could also be made more tolerant to environmental factors such as dampness, temperature and vibration as they can be hermetically (completely airtight) sealed. Manufacturers can also leverage eSIMs to optimise supply chain processes
