High-Speed eSIM Data for Global Travel

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.

Once you have installed the eSIM on your device, you can use it by following these steps:

1. Locate your installed eSIM and ensure the eSIM switch is turned ON.

iOS: Settings > Cellular > SIMs

Android (e.g., Samsung): Settings > Connections > SIM Manager

2. Confirm that Mobile Data is set to use this eSIM.

iOS: Settings > Cellular > Cellular Data

Android (e.g., Samsung): Settings > Connections > SIM Manager > Preferred SIMs > Mobile data

3. Confirm that Data Roaming is enabled for this eSIM.

iOS: Settings > Cellular > SIMs > Select your current eSIM > Data Roaming

Android (e.g., Samsung): Settings > Connections > Mobile Networks > Data Roaming

4. To avoid accidental use of your primary SIM's roaming data, we recommend turning off 'Allow Cellular Data Switching'.

iOS: Settings > Cellular > Cellular Data > Allow Cellular Data Switching

Android (e.g., Samsung): Settings > Connections > SIM Manager > Auto data switching

Setting mobile data limits on Android devices helps reduce data usage. You can choose your billing cycle, add data limits, and get warnings before reaching the limit. Follow these steps to set up mobile data limits.

For Samsung devices:

1. Open 'Settings' and tap 'Connections'.

2. Tap 'Data usage'.

3. Ensure mobile data is on, then tap 'Billing cycle and data warning'.

4. Tap 'Start billing cycle on' and set the date based on your arrival at the destination.

5. Enable 'Set data warning' and specify the data warning limit. For example, if your eSIM plan has 10 GB, you can set the warning to 8 GB.

6. Enable 'Set data limit' and specify the data limit. This option turns off mobile data when you reach the specified limit.

For Google Pixel devices:

1. Open 'Settings' and tap 'Network & internet'.

2. Tap 'SIMs'.

3. Ensure mobile data is on, then tap 'Data warning & limit'.

4. Tap 'Mobile data usage cycle' and set the date based on your arrival.

5. Enable 'Set data warning' and specify the limit.

6. Enable 'Set data limit' and specify the limit.

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.
