Nowadays, the majority of the companies are looking to minimize the gadget dimensions to the maximum possible limit. This presents them with the complex problem to integrate all the necessary electronics into small spaces. If you look at the scenario of SIM cards in mobiles there has been a gradual evolution with regard to the size of SIM slots. From traditional SIMs to the modern micro and nano SIMs there has been a visible change. But even then the chip makers are looking for alternatives that aim to reduce the hardware that houses them.
ARM the chipset maker unveiled a new design called Kigen that integrates SIM cards into the Internet of Things (IoT) devices. The so-called iSIM integrates into the same chip as the processor. Currently, most of the IoT devices depends on Wi-Fi for network connectivity. But by integrating the SIM cards into the IoT devices, it offers individual identity and IoT devices no longer need Wi-Fi for network connectivity. This is a good news for users of IoT devices. Since these devices need a working Wi-Fi connection, it exposes them to a range of security
