Start with the part of Korea that can actually create friction for your trip: arrival, money, food, shopping, apps, or a local rule that works differently than expected.
Before Korea is built around one habit: check the small thing before it becomes a tired, public, expensive, or awkward moment.
Choose the situation you are trying to avoid
- Before You Visit: entry checks, airport arrival, weather, transit, maps, phone data, and first-day backups.
- Before You Buy: K-beauty, sizing, tax refund, receipts, product labels, luggage space, and shopping mistakes.
- Before You Eat: ordering, kiosks, BBQ, allergies, spice, convenience stores, cafes, and food labels.
- Before You Use: Naver Map, KakaoTalk, taxi apps, delivery apps, translation, eSIMs, and payment recovery.
