What to Remember
Don’t forget to check all the important details.Cancellation and Refund
Refunds are available within 7 days of purchase.
However, refunds for the following month may be difficult to process, and refunds are not possible if the product has been used or already registered on your device.
Due to the nature of products used overseas, refunds requested due to reasons such as connection failure, unavailability, or eSIM malfunction may be due to issues with the device being used, unfamiliarity with settings, or temporary communication disruptions, rather than product issues. Therefore, refunds will only be processed upon approval after consultation with customer service (phone, email, KakaoTalk) using local Wi-Fi, etc.
Refunds requested after returning home without prior confirmation may not be processed.
Cancellations/refunds are only applicable to requests received during business hours (weekdays, 09:00-18:00).
