At Mobile World Congress 2023, Qualcomm announced the first GSMA certification of an integrated SIM (iSIM), with the technology now available for deployment on commercial devices. This is the version of the technology present on the Mobile Platform Snapdragon 8 Gen 2, which enables SIM features directly in the smartphone processor.
The GSMA security certification ensures that the iSIM complies with all IT protection standards and enables all the connectivity features offered by the latest generation eSIMs. Using iSIMs over eSIMs and the – now outdated, though still hugely used – physical SIMs allows manufacturers to save device space and reduce manufacturing and supply costsmaintaining all the functionality and safety guaranteed by the standards currently used in the sector.
What are iSIMs and the differences between physical SIMs and eSIMs
Qualcomm announced the news together with Thales, underlining that the new iSIMs are also “fully compliant” with the GSMA Remote SIM Provisioning standard. This means that each subscription can be managed remotely through all platforms used today by today’s standards. For iSIM a big step forwardwith the standard expected to account for almost 20% of the eSIM industry by 2027, in terms of deployment of new technology.
To date, the physical SIM represents the most widespread technology for managing the subscription to the cellular connectivity service on smartphones and other mobile devices. With a physical SIM, however, anyone intending to change operator must physically replace their card with a new one specific to the new provider, which can also represent a security risk. These problems have been removed by the arrival of eSIM (embedded SIM), programmable SIM cards integrated into the mobile device whose standard was certified in 2016.
The eSIM market is a growing market and, second Juniper Research, by 2027 will reach a value of 16 billion dollars. The eSIMs will not be for an arrival point, with the news arriving from MWC 2023 that anticipate what will be the next evolution. The iSIMIndeed, they implement all the functions and protection layers of the latest technologies inside the processor: if the eSIMs have to be soldered onto the logic board of the device, occupying part of the space, iSIMs are integrated into the device’s SoC.
The benefits are quite obvious: iSIMs save space on your device, enabling you to manage your cellular network provider subscription the same way you do today with SIMs and eSIMs. The operation of the iSIM also requires a considerably lower energy consumption than that of the eSIM, a factor which perhaps offers advantages that are perhaps not too evident in the field of mobile telephony, but which could open up enormous possibilities in the world of the IoT, giving the possibility of creating increasingly more small and effective.
