- Refunds are only available within 7 days of the purchase date.
(However, refunds for the following month may not be processed, and refunds are not possible if the product has 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 a product issue. Therefore, consult with customer service (phone, email, etc.) using local Wi-Fi, etc., and processing will only be done for approved cases.
- Refunds may not be possible for requests made after returning home without prior confirmation.
- eSIM products can only be registered and used on the initially registered device.
- Re-registration on another device is not possible after the first registration.

• Cancellation/refund requests are accepted only during business hours (Monday to Friday 10:00~18:00 / excluding Saturdays, Sundays, and public holidays), and cancellation requests received outside of business hours will be processed as received on the next business day (based on business hours).
• Please request cancellation and refund during business hours and receive cancellation confirmation.
