iSIM: The Next Big Thing

Telecom Tech Outlook | Monday, January 27, 2020

The iSIM, is designed mainly for the Internet of Things (IoT) devices for the sole purpose of security advantages. Keeping the data locked in a secure software on a secure hardware, it is virtually impossible to tamper with the software and networking hardware or break into an SoC.

FREMONT, CA: An increasing number of phones and gadgets are slowly starting to support eSIM, and we are now close to another change in the SIM technology. iSIM is an integrated SIM that fits into a device system-on-a-chip. Although there is not a lot of difference between eSIM and iSIM, the latter could change the way we use connected devices.

The SIMs will still allow customers to change carriers, data plans, and change their numbers as well. It will need the development of standards for remote provisioning as the SIM information is updated over a cellular network and not by changing the card. Both the SIMs can be used to list a single device on multiple operators, and in the near future, it will be possible to control credentials and access numerous devices using just a single tariff.

There is a slight difference between the eSim and iSIM. eSIM is attached to a gadget's processor, while iSIM is in the main SoC, embedded alongside the processor. This implementation of iSIM is important because of the high demand of security.

The iSIM, is designed mainly for the Internet of Things (IoT) devices for the sole purpose of security advantages. Keeping the data locked in secure software on a secure hardware, it is virtually impossible to tamper with the software and networking hardware or break into a SoC. Today's smartphones store a lot of our sensitive data like credit card information, biometric fingerprints, and this carries concerns for more security. Hence, this would imply that the iSIM could be applied beyond IoT and can pave the way for more use cases.

Implementing data security on the eSiM and iSIM could lead to ensuring better responsibility for online transactions and even social media accounts. What is needed is a system secure enough for consumers to trust a form of internet identity. And although this is not a new concept, the future of having devices tied to our identity is not too far ahead.
