What is an eSIM?
An eSIM ("embedded SIM") is a digital SIM built into your phone. Instead of inserting a plastic card, you install a mobile plan by scanning a QR code. For travelers this means you can buy a local data plan online and be connected the moment you land — no airport kiosks, no swapping tiny SIM cards.
Why eSIMs are great for travel
- Buy before you fly and activate on arrival.
- Keep your home number active for calls and texts while data runs on the eSIM.
- No physical SIM to lose, and you can store several plans on one device.
Do you need an unlocked phone?
Yes — your device must be carrier-unlocked and eSIM-capable. Most phones from 2019 onward support eSIM.
