Treat activation details like a private setup credential
An eSIM is provisioned digitally. Depending on the delivery method, the QR code, activation code, direct installation link, or manual SM-DP+ details can tell a device where and how to download a cellular profile. The GSMA describes QR codes as a way of supplying provisioning information to the device; Apple documents QR, link, manual-entry, and carrier-based eSIM setup methods.
That does not mean every detail has the same reuse or expiry rule. It does mean you should not treat these details like a public discount code. Keep them within your own account, email, password manager, or an encrypted personal note—not in a public post, group chat, listing, or unprotected photo album. Use the decision table below as a quick rule, then follow the exact plan instructions if they say something more specific.
| Detail | Safe place | Do not do this |
|---|---|---|
| QR code or activation code | A protected personal account, password manager, or encrypted personal note. | Post it publicly, send it to an unverified helper, or leave it in a shared photo album. |
| Manual setup information | Use only when the plan instructions call for manual entry. | Copy an address or value from an unrelated online guide. |
| Order email or account link | Your inbox and the official JETZIO account route. | Forward a sign-in link or publicly show the full order information. |
| Troubleshooting details | A verified support request with plan, device, and error context. | Send your password, full card number, passport, or activation credential by default. |
Activation methods and reuse policies differ by provider. Preserve the original details and follow the plan-specific instructions before trying a replacement or reinstall.
What to save before you travel
Save only the information you need to complete installation or ask verified support for help. Keep it available offline in case the arrival connection is not ready yet, but do not make a second unsecured copy just for convenience.
- The verified purchase email or a secure account link for My eSIMs.
- The plan name, destination, validity, and support contact—not an unnecessary screenshot of every account detail.
- The QR code or activation information only in a protected personal location, if your plan requires it for installation.
- Offline travel essentials such as your accommodation, maps, and support instructions separately from eSIM activation credentials.
What not to share
Never publish or forward a QR code, activation code, manual SM-DP+ details, order sign-in link, account password, payment-card details, passport image, or a full device identifier. A legitimate support agent does not need your account password or full payment card number to help with an eSIM issue.
If you need help, open the JETZIO account or Help Center yourself and use a verified support channel. Do not rely on a social-media reply, a lookalike email, or a link sent by an unknown person.
If you cannot find the QR code or the install fails
First, check the verified purchase email and My eSIMs account for the plan’s current installation instructions. Do not repeatedly scan a code or delete a partly installed profile just to start again; the provider’s instructions determine whether the same activation details can be reused.
If the profile is already installed but data is not working, use the arrival troubleshooting guide before requesting a replacement. If the installation information is genuinely unavailable, contact verified support with the order email, destination, plan name, device model, and the exact message you see—without sending activation details unless support specifically requests them through a secure route.
How this guide was prepared
This guide was prepared by JETZIO’s travel research team on 22 October 2026. It uses the GSMA’s explanation of eSIM remote provisioning and Apple’s current eSIM installation methods as primary technical references. The exact contents, expiry, reuse policy, and reissue procedure for activation details depend on the plan provider. This is practical security guidance, not a claim that every QR code has identical behaviour.
