eSIM

An eSIM (embedded SIM) is a programmable chip soldered into a phone, tablet or watch that holds a carrier profile. You activate service by scanning a QR code or using a carrier app rather than swapping a plastic SIM.

Why it matters

eSIMs make it quick to switch carriers or add a local data plan when traveling, and allow dual-SIM use without a second tray. They cannot be lost like a physical card, though moving a line to a new phone requires a transfer.

Not all carriers and devices support them.

Example

1. Buy a data plan online
2. Receive a QR code
3. Settings > Mobile > Add eSIM > scan
4. Choose which line is used for data

The profile downloads in under a minute on Wi-Fi.

Common mistakes

• Deleting an eSIM profile before confirming you can restore it, since many cannot be reused.
• Buying a device that is carrier-locked.
• Assuming an old phone supports eSIM.
