How does an eSIM differ from a SIM?

A SIM card is a physical chip card you slot into your phone normally in a tray that pops out from the side. A SIM usually has 3 sizes; Mini-SIM, Micro-SIM and Nano-SIM, Its card's most significant benefit is its portability. You can switch between devices in seconds, and you won't have to contact your carrier

An eSIM is an embedded SIM card fitted into the phone's motherboard. It runs on the same networks as standard SIM cards, so there's not much difference in how they work outside the initial set-up and transferring of your number and plan.

An eSIM performs the same function as a physical SIM card but removes the requirement to physically swap SIMs when switching between network providers.
