I used this SIM in China and it was really convenient because I could use KakaoTalk and YouTube. I highly recommend purchasing a lot of Gigabit memory since you can't watch KakaoTalk or YouTube even when using hotel Wi-Fi!

I've been using it well and the data is fast. I'll use it again next time if I get the chance.

I traveled to Inner Mongolia, and the internet worked well except when I went deep into the desert. I used it well~~~^^

Highlights

The journey has already begun,
USIMSA

Data is essential while traveling! If you want to start your trip comfortably, I recommend data eSIM. It is a product that can be used by simply setting up your smartphone without a separate SIM replacement. Stop carrying around a heavy router! Yousimsa's eSIM allows unlimited use of SNS without a VPN, making it perfect for sharing photos and videos in real time.

Start your journey lighter, more conveniently, and more affordably.

Cancellation and Refund

Refunds are only possible within 7 days of the purchase date.
However, refunds for the following month may be difficult to process, and refunds are not possible for products that have been used or have already been registered to the terminal.
Refund requests due to reasons such as activation failure, unavailability, or eSIM failure due to the nature of products used overseas may not be due to product issues but rather to the terminal being used, insufficient settings, or temporary communication failures. Therefore, only cases approved after consultation via the customer center (phone, email, KakaoTalk) using local Wi-Fi, etc. will be processed.
Refunds requested after returning to Korea without prior confirmation may not be processed.

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