What is an eSIM?
An eSIM is an embedded SIM card built directly into your phone’s hardware. It works like a physical SIM card, but it’s fully digital—no swapping cards or visiting a store required.
With an eSIM, you can purchase a mobile data plan, install it on your device, and connect to a local mobile network at your destination in minutes.
