ESIM

Esim stands for "eSIM," which stands for embedded SIM. It's a tiny chip that can be used in your phone or other device instead of a regular SIM card. The esim chip is preprogrammed with your cell phone provider's information, so you don't need to swap out SIM cards when you want to switch providers. You can also store multiple provider accounts on your esim chip, so you can switch between providers without swapping out cards.
