A valid K-ETA exempts you from Korea's arrival card. Being visa-free does not. That inversion catches out the travellers most confident they are fine — Americans, Canadians, Britons, Australians and EU citizens arriving without a K-ETA.

Good as isEverything worked very well. Even we have some restrictions about Esim registration in Turkiye, I could able to use it as soon as I landed in Denmark. And I got all the questions answered in a few minutes. I’ll be using it again and again for sure!설치가 간편하고 빠른 속도와 안정된 접속으로 여행 기간 동안 잘 사용 했어요.Worked well, stable fast. recommendationGreat experience! Everything worked exactly as expected. The eSIM installation took less than two minutes and was very easy to set up. I had reliable service throughout my trip in the United States with no issues. I will definitely use it again. Highly recommended!Great value for my Thailand trip and setup was quick. Dropped one star only because I burned through my data faster than expected — go a size up if you stream. Would buy again.
