Verified
Why this list exists: Korea is one of the most tech-advanced countries in the world — but that same technology systematically locks out foreigners. App registration walls, identity verification that requires a Korean national ID, taxi apps that silently reject foreign numbers, KTX tickets that can only be booked through one opaque website. These issues are real, frequent, and almost never covered in standard travel guides.
