eSIM for the USA

No complicated checks needed. The AirZlink app features a built-in smart detection tool that automatically identifies and instantly confirms your device's eSIM compatibility, guiding you through the next steps.

Data from your eSIM plan can only be used within the validity period. Once the plan expires, any remaining unused data will be forfeited.
If you have any questions, please feel free to contact our support team: support@airzlink.com

No. An eSIM can only be installed and used on one device.

eSIMs cannot be transferred between devices. For example, if you delete the eSIM from your current device, it cannot be reinstalled or reactivated on the same or another device.

This is determined by the technical design of eSIM: once activated, each eSIM is securely bound to the initial device. This one-to-one association helps ensure user and device security. If an eSIM is removed due to device replacement or operation error, you will need to purchase a new eSIM for that device to get mobile connectivity.

Therefore, please confirm that you intend to use the device continuously before installing. If you have any questions or need further assistance, please feel free to contact our support team.

There could be several reasons why your eSIM is not working properly. Troubleshooting a few steps can help identify the issue and get you connected quickly.

### Where can my eSIM be used?
Please remember that your eSIM can only be used within its coverage area. For example, a France eSIM only works in France. If you install it outside the coverage area, you need to reach the coverage area to connect.

### How to identify why your eSIM is not working
If you are in the coverage area but cannot use the eSIM, follow these steps.

### A) Ensure your eSIM is installed correctly
If installed correctly, you should see the eSIM in your device's SIM settings. If possible, check the app for a success message.
Be sure to give your eSIM a unique label to easily identify it.
If you don't see the eSIM in settings, please read: Why can't I find my installed eSIM on my device?

### B) Ensure you have followed connection steps
Once installed, you need to adjust a few settings to connect. Steps vary by device but always include:

1) Ensure eSIM is ON
2) Ensure eSIM is selected for Data
For eSIMs with calls/SMS, ensure it's selected for those too.
3) Ensure 'Airplane Mode' is OFF
This is a common reason for connection failure. Airplane mode disables all wireless communication. Turn it off and wait a few seconds for the device to search for networks.
4) Turn on Data Roaming
Some eSIMs require data roaming. Check 'Access Data' instructions.
For iOS, you can turn roaming on for individual SIMs. Ensure it's OFF for your primary SIM to avoid charges.
For Android, roaming often applies to all active SIMs. Ensure it's OFF for your primary SIM.

### C) Manually select network
Your eSIM should connect to at least one network in the area. Usually, it connects to the strongest one automatically. Sometimes it might pick the wrong one.
You can find the supported networks in your plan details and manually select one.

### D) Temporarily turn off other SIM cards
If your device supports multiple active SIMs, temporarily turn off others that might interfere.

### E) Adjust network mode
Sometimes switching network modes helps. If trying 5G, switch to 4G/LTE or 3G.

iOS: Settings > Cellular > Select SIM > Voice & Data > Adjust mode
Android: Settings > Connections > Mobile Networks > Select eSIM > Adjust mode

Once working, you can try switching back to your preferred mode.

### F) Restart device
If all else fails, restart your device. This refreshes the connection state.

### G) Check signal coverage
If nothing works, signal strength in your area might be too weak.
