Apple has had support for eSIM since the iPhone Xs/XR, but this year it is going all in by ditching the physical SIM card slot for all iPhone 14 versions sold in the U.S. While models sold in other countries will have support for both physical and virtual SIM, Apple could eventually remove the SIM slot in more countries depending on availability. The precise instructions vary from region to region. For this guide, we’ve focused primary on the U.S. market.

eSIM is a substitute for a physical SIM that’s embedded in the phone’s circuitry so users can easily swap between SIMs. It also enables people to host more than two SIMs. The iPhone 14 will be able to host up to eight SIMs at once. So, how easy is it to load a new eSIM on the iPhone? It should only take a few steps.
