eSIMS provide future designs with plenty of opportunities, especially those in the IoT industry. But what exactly is an eSIM, and why are they going to help future IoT systems such as global asset tracking?

What is an eSIM?

An eSIM is an embedded SIM card that, unlike a traditional SIM card, is only the chip part of a SIM. These are embedded directly into designs and allow for on-the-fly reprogramming. This reprogramming can be done in a multitude of different ways, including NFC, phone call, or programming jig. Once programmed, the device using the eSIM can connect to a network, and operate as if it was connected to a physical SIM card. As such, an eSIM eschews the necessity to switch physical SIM cards or phones when you want to change carriers.
