가끔씩 먹통 수준으로 안 터질때가 있지만 가격 생각하면 천사입니다

지하나 건물 안 혹은 그냥, 엄청나게 안터지는 구간이 있긴 하지만 가격 생각하면 괜찮았아요

It's simple to register, and there's no fear of losing it while changing a SIM, and it's really convenient! Before leaving the country, I registered for the SIM and boarded the plane, and as soon as I arrived in Japan, I was surprised that it worked so well haha. (It is convenient to capture the visit japan QR code as the data may not work well during immigration in Japan)

I'm angry. I bought it for the first time because there were many reviews saying that it exploded well. Reviews seem to be alba. After arriving at the airport in Japan, WAUG sent me a voucher saying it was an unusable QR, so I inquired and exchanged it for a new voucher about 2 hours later. I couldn't do anything at the airport and just threw away 2 hours. On the day of the start of the trip, I was stressed out and annoyed. Responses to inquiries are also very slow. please refer to this.

Don't sell fake products. I heard it's a local network? I use the au network through China Hong Kong mobile roaming. What kind of local network is this? I have to turn on roaming, so my phone turns off, the battery wears out even more, the speed is lacking, you dirty bastards, don't cheat and sell it.

Cancellation and Refund

- Refunds are available only within 7 days from the purchase date.
(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 the device.)
- Due to the nature of products used overseas, refund requests due to connection failures, unavailability, or eSIM defects may be due to issues with the device being used, inexperienced settings, or temporary communication failures, rather than product issues. Therefore, refunds will only be processed after consultation with customer service (phone, email, etc.) using local Wi-Fi, etc., and upon approval.
- Refunds may not be processed for requests made after returning to your home country without prior confirmation.
- eSIM products can only be registered and used on the device they were initially registered on.
- Once registered, re-registration on another device is not possible.

Cancellations/refunds are applicable only to requests received during business hours on weekdays (09:00-18:00).
