BESTRegister eSIM in advance in Korea before departure, and turn on and use the newly registered eSIM upon arrival. I asked the WAUG staff if I could register in advance, but I don't know. If you can't register with QR, you can proceed by entering SM-DP + address and activation code. I was nervous because it was my first time using eSIM, so I searched for this and that. After reading a blogger's post asking me to register in advance in Korea, I registered at Incheon Airport. In Hong Kong, you need to get a tourist certification (?), but you can do that in Korea as well. You need to take a passport photo to register. It's good to register in advance at a place with good Wi-Fi.
Highlights
Introducing the 'Yousimsa' unlimited eSIM, allowing you to enjoy unlimited data freely without worrying about data limits.

In particular, Yousimsa eSIM is a member of GSMA (Global System for Mobile Communications Association) and can be used safely with global standards.

What to Remember
Don’t forget to check all the important details.Cancellation and Refund
(However, refunds for the following month may not be processed, and refunds are not possible for used products or products already registered on the device.)

Therefore, consult with customer service (phone, email, etc.) using local Wi-Fi, and refunds will only be processed upon approval.
- Refunds may not be possible if requested 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.
- Re-registration on another device is not possible after the initial registration.
• Cancellation/refund requests must be received during business hours (Monday to Friday 10:00-18:00 / excluding Saturdays, Sundays, and public holidays), and cancellations received outside of business hours will be processed on the next business day (based on business hours).
