What is eSIM?

eSIM, short for Embedded SIM, is a digital SIM card embedded directly into a device, eliminating the need for a physical SIM card. This technology allows users to switch between mobile networks without changing SIM cards, making it incredibly convenient for travelers or anyone who wants to manage multiple phone numbers on one device.

How Does eSIM Work?

eSIM works by downloading a digital SIM profile onto your device. This profile contains the necessary information to connect your device to a mobile network. Once the profile is activated, you can use your device just like you would with a traditional SIM card, but with the added flexibility of easily switching carriers or plans.
