It was my first time doing esim, so I was a bit confused, but after reading the explanation and following it step by step, it was simpler than I thought.

I used it very well at a really good price. I bought it much cheaper than my friends and it works well, so I will continue to buy from here. I also bought the European one.

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 locally overseas, refund requests due to reasons such as activation failure, unavailability, or eSIM defects may be due to issues with the device in use, unfamiliarity with settings, or temporary communication disruptions, rather than product issues. Therefore, refunds will only be processed upon approval after consultation through 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).
