eSIM recommendations

Hi everyone

I’ll be visiting South Korea next week and planning to spend time in both Seoul and Busan. I’m currently looking for a good eSIM option for around 2 weeks.

Does anyone have recommendations for reliable eSIM providers that worked well for you in Korea?

Also, has anyone tried the WOWPASS eSIM (SK Telecom)?. I’m considering it but would love to hear real experiences before getting it.

Thanks
