Will your iPhone work with a travel eSIM?
Check the exact iPhone model and sales region, then carrier-lock status and provider compatibility. A familiar model name alone is insufficient because regional hardware differs. For a different carrier's travel profile, the phone must be unlocked. Buying an eSIM does not remove an existing carrier lock or add support to hardware that lacks it.
Four checks before choosing a package
- Record the model number and sales region in Settings > General > About, plus the installed iOS version.
- Use Apple's current model/region documentation and the provider's compatibility list for that exact variant.
- In Settings > General > About, check Carrier Lock. Apple says an unlocked phone shows No SIM Restrictions. If locked, ask the original carrier about unlocking before buying another carrier's plan.
- Confirm the travel provider accepts the exact device and destination package, including any active-line limitations.

Can two eSIMs be active together?
Apple documents two active eSIMs on iPhone 13 models and later where the regional hardware supports eSIM. Earlier compatible models may use a physical SIM plus eSIM. Stored profiles are not the same as simultaneously active lines, and cellular data uses one network at a time. Check the exact model before assuming a home eSIM and travel eSIM can both stay on.

Why might Add eSIM be missing or setup fail?
| Check | Next step |
|---|---|
| Regional hardware support | Confirm exact model and sales region with Apple. |
| Carrier and package compatibility | Ask the carrier/provider before buying a second activation code. |
| Software and connectivity | Use supported current iOS and a reliable setup connection. |
| Installed line or an error message | Check whether the line already appears; follow Apple troubleshooting and contact support. |

Using the phone in mainland China
Separate where the phone was sold from where you will travel. A compatible international device using a travel service is a different case from eligibility for a mainland-carrier eSIM. Regional model rules change, so use Apple's current linked documentation and the provider's exact-device check. App access and data routing are separate plan questions; compatibility does not settle them.

Prepare the details support needs
- Exact model number, purchase region and iOS version.
- Carrier-lock status and the plan name.
- The precise error text and whether the travel line already appears.
- Order reference and device identifiers only through the provider's private support channel.

Supported iPhones allow separate lines for calls and data. iPhone 13 models and later support two active eSIMs, subject to regional hardware support. Stored profiles are different from active lines; one cellular data network is used at a time. Verify exact regional model.

Check connectivity and software, toggle airplane mode or the installed line, and restart. Collect the error and device details for carrier support. Troubleshooting guidance does not establish why a specific device failed.
