Which devices support eSIM?
•
Various devices such as iPhone XS or later, Galaxy S20 or later, and Pixel series support eSIM, but compatibility may vary depending on model, region, and carrier policies.
•
If you dial *#06# in the Phone app and see an EID (eSIM Identification Number), your device is likely eSIM-compatible.
•
Devices with Country Lock or Carrier Lock may not be able to install an eSIM profile from another carrier, so please check if your device is unlocked.

An error message appears when installing the eSIM
•
If you see the “Cannot be activated” the eSIM may actually have been installed correctly. Check if it’s working as intended.
•
If “Cannot add cellular plan” or “Cannot add eSIM” appears, the same eSIM profile might already be installed.
•
If “Cannot activate eSIM” appears, it could be because the eSIM was installed before entering Korea and hasn't yet connected to the carrier network. Try again after arrival.
eSIM keeps showing "Activating..." during installation
•
If you install the eSIM before arriving in Korea, you might see the “Activating…” status for 1-2 hours due to the lack of a live network connection.
•
Once you arrive and connect to a network, check if the activation completes successfully.
Why do I need identity verification?
•
Without identity verification, calls and texts will not be available, and you can only use data.
•
After verifying your identity in Korea, you will be able to receive calls and texts.
•
To make calls or send texts, you may need an SKT top-up service. If needed, refer to the link below:
Can I send texts or make calls?
•
If you have completed identity verification after arriving in Korea, receiving calls and texts will be enabled automatically.
•
Outgoing calls and texts require an SKT top-up service. Check the details via the link below:
Can I get a refund?
•
If eSIM is not used and it is within the validity period, the refund may be possible.
(If refund is possible, ‘Refund’ button will appear at the QR code section of the reservation page.)
•
Refunds are not available once the eSIM QR code has been installed.
•
However, if your device is carrier-locked (restricted from using foreign SIMs) or does not support eSIM, you may be eligible for a refund.
•
Refund processing can take a few days, so please keep this in mind when applying.
