How the iSIM might give your next phone a huge battery


The iPhone X’s notch turned out to be the “next big thing” in phone design, but the next (next) big thing might not even be noticeable to the naked eye. ARM has developed new iSIM technology that might eventually see the trusty, but ever cumbersome SIM card going away for good.

But for now, temper those expectations as it’s making its debut in Internet of Things (IoT) devices. This new SIM replacement is integrated right into the processor and thus, takes up far less space than even eSIM, the impressive SIM card-less tech recently used in the Google Pixel 2 and Apple Watch 3, let alone an entire SIM card slot.

Conceptually, iSIM isn’t too different than the eSIM, though its dimensions are stark by comparison. Compared to ARM’s new tech that is said to be smaller than a “millimeter squared”, eSIM consumes 6 x 5mm of space inside of the phone – precious space that manufacturers could use to boost RAM or pack in a larger battery.

In with the new SIM

The main motivator behind the creation of iSIM is to make way for new hardware innovation, which given the diminutive size of many IoT devices, any extra space is a good thing.
