eSIMs are as safe as physical SIMs — and in some ways safer. Here is what to know.
eSIM technology is built on the same trusted standards as physical SIMs, with a few extra security benefits.
Harder to steal
Because there is no physical card, a thief cannot pop out your SIM to hijack your number. The eSIM stays locked inside your device.
Encrypted profiles
eSIM profiles are downloaded and stored securely, and each is tied to your device. The standard is maintained by the GSMA, the global mobile industry body.
Smart habits abroad
- Use a screen lock and biometrics.
- Prefer cellular data over open Wi-Fi for sensitive tasks.
- Keep your home number for banking verification texts.
