SIM cards will soon be attached to microprocessors to save space

Each millimeter is also important when you build electronic devices that are increasingly complex and increasingly compact. Relatively large space of SIM cards has long been a headache for hardware manufacturers. Recently, ARM chip manufacturer had the answer, an integrated component named iSIM Attached directly to the chip as microprocessor.

ARM says iSIM will occupy 'part of a square millimeter' while the current standard SIM - Nano SIM - measures about 12.3 x 8.8 mm, not to mention the hardware used to store them on the device. suffered. According to ARM, this SIM not only saves space but more importantly reduces costs. Instead of paying '10 cents' for each card, the manufacturer will only have to pay a 1-digit coin.

But don't assume that the SIM card will disappear. The above technology was developed with the original goal of IoT devices, like wireless sensors that need mobile services to report what it detects. The purpose of ARM is to reduce the cost of these products to the lowest possible level, so that their chip designs become more popular in the IoT market that will flourish in the coming years.

This raises an important question as to whether or not mobile network providers approve. Phone makers now have a solution to replace Nano SIM - a small 6 x 5 mm chip called eSIM - but the level of adoption in the industry is still very slow. Even so, eSIM is increasingly appearing on many recent tablets and wearable devices on Google's latest Pixel phones. Perhaps it will only be a matter of time before this technology is more widely used.

ARM hopes that iSIM will be responsive to carriers because of its ability to meet the necessary standards and ultimately they themselves want to see the network-connected IoT devices they offer, because that means they get more customers.

ARM said it has sent iSIM's design to its partners and hopes to see these chips appear later this year.
