Glossary of eSIM Terms
Every term we wish someone had explained to us before buying our first eSIM plan. No jargon. No assumptions.
eSIM stands for 'embedded SIM.' Instead of inserting a tiny plastic SIM card into your phone, you scan a QR code to download a mobile plan directly to your device. It works exactly like a physical SIM — same towers, same speeds, same coverage — but it's invisible, instant, and can't be lost. eSIM is ideal for travel because you can buy a plan before you leave and activate it the moment you land.
