The eSIM/Embedded SIM, or as it's more formally known, embedded Universal Integrated Circuit Card (eUICC), is smaller again at 6 mm in length and 5 mm in width and is soldered onto a device's motherboard at the point of manufacturing while having the same functionality as a removable SIM. It has M2M (Machine to Machine) and Remote Provisioning capabilities. Now a GSMA standard, it wont be long before we see the eSIM become standard in other top tier handsets from Apple and Samsung, quickly followed by the others.
