eSIM Service

 When you convert to an eSIM, you're simply transitioning from a physical SIM card to an eSIM on your current device. On the other hand, transferring an eSIM involves moving either your physical SIM card or existing eSIM to an eSIM on a new device.

All individual customers, both prepaid and postpaid, using devices that support eSIM can take advantage of this service.

No, corporate customers looking to utilize eSIM services should visit an AIS Shop for assistance.

The phone number you wish to process must have both VoLTE and VoWiFi services activated. Additionally, all security features on the device should be enabled. Follow these steps:

1. Log into iCloud on the iPhone (for both devices involved in the process).
2. Activate Apple ID's Two-Factor Authentication.
3. Enable Face ID or passcode lock.
4. Register for iMessage.

Yes, for a complete transaction, once you've successfully connected to a strong and stable Wi-Fi network, your original phone should remain close to the new phone throughout the transfer process (no more than 1 meter away).

If customers are not the ones performing the SIM transfer transaction, they should press "Cancel". However, if they accidentally press "Transfer", it won't have any consequences. This is because the next step would require entering a Verification Code. Without the correct information, the SIM transfer process cannot proceed.

No, you can't turn this off as this service originates from the Samsung device itself.

No, it can't be used. The system will deactivate the original SIM immediately. It is recommended to remove and destroy it.

The data will not be transferred. It's advisable to import the contacts from the SIM card to the phone's Phonebook and back up the data on iCloud or Samsung Cloud before proceeding.

Reversion can only be done for eSIM-to-eSIM transfers between devices. If you want to revert back to a Physical SIM card, you will need to contact an AIS Shop.

Restart your device and try the activation again.
Important: Before restarting, make sure you remember your device passcode, as you’ll need it to unlock your phone after the restart.

(On Android, see example screen below.)

This happens when the myAIS account you’re logged in with is different from the one used to purchase the eSIM on the AIS Online Store.

The system allows up to 3 incorrect attempts. If exceeded, please visit any AIS Shop nationwide to complete your eSIM activation.

*This cannot be done via the Call Center, as in-person ID verification is required.

This may occur for two reasons : 

• Your device has more than 8 eSIM numbers. → Please delete any unused eSIMs and try again.
• Your Wi-Fi connection was unstable during activation. → Please visit any AIS Shop to get a replacement eSIM and reactivate it.

eSIM activation via the myAIS app is automatic and cannot be switched to QR code once selected.
