eSIM explained: what it is and how it works
An eSIM is a digital SIM built into your phone. Instead of inserting a plastic card, you download a data plan in minutes – ideal for travelling without roaming fees and without swapping SIM cards.

eSIM stands for “embedded SIM”: a small chip that is permanently built into your device. It does everything a physical SIM card does and connects you to a mobile network, but the plan is installed digitally, by scanning a QR code or tapping a button in an app.
Most current smartphones, tablets and smartwatches support eSIM. One device can store several eSIM profiles, so you can add a travel data plan next to your usual contract and switch between them in your settings.
