Community prompt: What emergency detail should people save in Incheon?

Experience

This is a Settly Team starter question for the Incheon community, not a user-submitted story. If you have handled 119, 112, embassies, hospitals, Korean address text, housing contacts, and trusted local help in Incheon, share the detail another foreigner would need. Helpful answers include neighborhood or station, visa or stay type, timing, approximate cost, documents, place or office visited, what blocked you, and what finally worked. Do not include passport numbers, residence numbers, bank details, reservation codes, exact room numbers, or private contact details. For visa, tax, medical, or legal decisions, check official sources before acting.
