Like a traditional SIM card, an eSIM stores the data your device needs to use the EE network. ‘eSIM’ simply means an embedded SIM, but unlike a physical SIM card, an eSIM is already built into your device.
It also allows you to have multiple lines on a device, that you can switch between. And it’s more secure - someone can’t remove the physical SIM card if your device is lost or stolen.
In just a few simple steps, you are ready to make calls, send messages, and browse the web.
