Thales has announced that its integrated SIM (iSIM) solution has now been certified by the GSMA and is ready to be deployed commercially with Qualcomm’s Snapdragon 8 Gen 2 platform. In 2021, Thales, Vodafone and Qualcomm had shown a working demonstration of the iSIM.
What is iSIM? And why is it important?
iSIM is a type of SIM that is directly integrated into the processor of the device. As the next step of SIM evolution, iSIM offers significantly more space reduction than eSIMs do and lowers power consumption. This is also part of a bigger trend where we have seen multiple components, such as the modem, getting integrated into the processor of the device. Along with smartphones, iSIMs also bring multiple benefits to the IoT ecosystem.
Currently, around 20% of smartphones shipped in 2022 were eSIM capable. The adoption of eSIM in smartphones has been slower than what was expected three years ago due to a variety of reasons. However, the biggest hurdle has been the need for additional components required to add eSIM capability.
For iSIMs, it would be a different case because the SIM is integrated into the processor and its adoption, unlike the eSIM, will be dependent on the support of chipsets. The iSIM will see faster adoption than the eSIM because the number of players providing chipsets is limited. While we have already seen multiple IoT devices with iSIM, the first iSIM smartphone is expected in 2024.
