- Refunds are available only within 7 days of the purchase date.
(However, refunds for the following month may not be processed, and refunds are not possible for products that have been used or already registered on the device.)
- Due to the nature of products used overseas, refund requests due to activation failure, unavailability, eSIM defects, etc., may be due to the device being used, lack of settings, or temporary communication issues, rather than product problems. Therefore, processing will only be done after consultation with the customer center (phone, email, etc.) using local Wi-Fi, etc., and approval.
- Refunds may not be possible for requests made after returning to the country without prior confirmation.
- eSIM products can only be registered and used on the device initially registered.
- Re-registration on another device is not possible after initial registration.
