Please make sure that the model of the mobile phone you wish to use eSIM with supports eSIM service before purchasing. [Refer to the details page]
If you are a customer who has set up a mobile phone protection service, you must unlock the SIM card and deactivate the mobile phone protection service at your mobile carrier's customer service center or on their website in order to use the service.
After purchase, product information (QR code) will be sent via email and KakaoTalk notification. Exchanges and refunds are not possible after the QR code is sent or scanned.
To register the eSIM product you purchased on your device, you must have data available (cellular network or Wi-Fi connection mode).
If you delete the registered cellular plan after scanning the QR code, eSIM cannot be used, so please maintain the plan until use is terminated.
It can be pre-installed at the departure location and the usage period starts from the time of connection to the destination network.
If possible, turn off data roaming for your domestic telecommunications company before leaving the country. (Incorrect operation may result in roaming charges overseas.)
Depending on the communication environment of the local telecommunications company, data use may not be smooth in some areas, and depending on the model used, if the frequency band does not match that of the local telecommunications company, it may connect to 3G or 2G.
The terms and conditions of the telecommunications company that provides the service apply and product options (data provision, number of days of use, promotions, etc.) may change without prior notice.
If eSIM registration is not successful or cannot be used after registration (※ eSIM must be installed), please contact the customer service center. We cannot provide assistance after purchase, and returns/refunds are not possible. [For domestic use in Korea: 1566-9070 / When calling from overseas: 02-775-1401]
Once deleted, eSIM cannot be rescanned or recovered. If you are unable to use the service due to your own negligence or lack of understanding of the usage instructions, as above, refunds are not possible.
Exchanges and refunds are not possible after the QR code has been sent or scanned.
In case of unavailability due to local telecommunications company network maintenance, natural disaster, or other reasons, no refund will be made.
