A short definition
eSIM is short for embedded SIM. On a compatible phone, you can download and install a mobile plan by following the provider’s instructions, without inserting a physical SIM card.
Compatible phones can store multiple eSIM profiles. You can keep your regular number and add a separate plan for travel data.
eSIM vs physical SIM
| Physical SIM | eSIM | |
|---|---|---|
| What it is | A small plastic card you slot into your phone. | A digital profile loaded into a chip already built into your phone. |
| Getting it | Buy a physical SIM online, in a shop or at an airport counter. | Buy online and follow the setup instructions sent by email or provided in the app. |
| Swapping plans | Open the SIM tray with an eject tool and replace the card if needed. | Scan a new QR. Keep both profiles. Switch in Settings. |
| Travel | Roaming fees, or buy a local SIM at the airport kiosk. | Install your travel eSIM and activate it according to the provider’s instructions. |
| Compatibility | Requires a compatible SIM slot and support for the local network. | Requires an eSIM-compatible phone. Support can vary by model and sales region. |
