ARM Holdings on last Friday has announced a new solution which is called as iSIM to integrate the functionality of SIM into connected devices – without requiring a traditional SIM card or even any type of embedded SIM (eSIM).
The new solution is aimed to not just help device makers but also to reduce the sizes of future connected devices, but also to drop their prices – eventually expanding their use cases. It merely means that it’s the time to say bye to the traditional SIM cards as the new chip design is primarily designed for devices which enabled IoT (Internet of Things) applications and isn’t something specific to smartphones or tablets.
The iSIM has been integrated with the GSMA Embedded SIM specifications to help the device makers and service providers to offer cellular connectivity on the devices which is compatible with IoT. Since the new solution is available as a part of a single IoT SoC, which also includes an MCU and a cellular modem, it doesn’t require any separate SIM card and full SIM functionality is available with the help of an ARM Kigen operating System that is a low footprint, scalable software stack available as an open system.
It is more important to note that the cellular network delivery through the iSIM will be too much identical to what one can get from a standalone SIM card. This also means users will get a chance to move from one network operator (MNO) to another with ease. It is the cost and the size of the hardware that are presumed to be majorly impacted once device manufacturers will start deploying the new age of solution.
Some of the giant companies such as Apple and Samsung brought Nano-SIM and mini-SIM card facility for its users. Likewise, Google added eSIM to its Pixel 2 family to start the life of cellular connectivity on mobile devices to the next set of data. But it is not revealed properly that whether these companies will choose the latest ARM solution for their new mobile devices.
The ARM has already started testing the iSIM with some industry partners and has expected to see the chip-based solution powering new connected devices sometime by the end of 2018.
