Download Naver Map, not Google Maps
Google Maps cannot route walking or driving directions properly in Korea due to mapping laws. Naver Map and Kakao Map have full English interfaces and accurate transit routing - set one up before you land.

South Korea Travel Guide: Essentials, Tips & Mobile Data
Seoul and beyond: T-money, Naver Maps over Google, food culture, the best seasons, curated traveler tips, and mobile data via eSIM.
South Korea layers palaces and hanok villages under neon high-rises, with Seoul's food scene, shopping and nightlife leading the way, Busan offering beaches and seafood markets, and Jeju Island's volcanic coast a short flight south.
It is one of the most convenient countries on earth - superb transit, 24-hour everything, spotless streets - but it runs on its own digital ecosystem: Google Maps barely works here, so set up Naver Map or Kakao Map before you arrive.
Seoul is a city that feeds you at 2am and gets you home on a subway that still looks new. Palaces and hanbok rentals sit next to basement fried-chicken joints and neon noraebang. Then Busan gives you sea air and fish markets, and Jeju gives you a volcanic island that Koreans treat as their own holiday default.
Download Naver Map, get a T-money card, and stop trying to make Google work. Korea has its own excellent internet universe. Once you are inside it, the country is almost unfairly easy.

Use T-money for everything
Buy a T-money card at any convenience store, load it with cash, and tap through subways, buses, taxis and konbini purchases across the country. Transfers between bus and subway are discounted automatically.
Eat in the markets and side alleys
Gwangjang Market's bindaetteok and knife-cut noodles, tent bars (pojangmacha) at night, and any barbecue alley full of office workers deliver the Korea food experience better than polished tourist restaurants.
Convenience stores are a third restaurant category
CU, GS25 and 7-Eleven sell onigiri, ramen, banana milk and city-view seating. A late-night triangle kimbap on the Han River is a legitimate Seoul memory, not a compromise.
Book popular restaurants and palaces, walk into the rest
Gyeongbokgung, the more famous barbecue rooms and anything with a two-hour queue on Instagram want a reservation or an early arrival. Neighborhood spots and markets do not. Follow office workers, not influencers, for dinner.
よくある質問
South Korea の旅の疑問に答える
Does my phone support eSIM in South Korea?
Unlocked iPhone XS and newer, Pixel 3 and newer, and Galaxy S20 and newer all support eSIM and work well on Korea's networks, which are among the fastest anywhere.
How much data do I need for a week in Korea?
Naver Map routing, Papago translation and photo uploads make Korea data-heavy - budget 2 GB per day, or around 15 GB for a week. Unlimited plans are worth considering since the networks are fast enough to actually use them.
Is there mobile signal in the Seoul subway?
Yes - full-speed mobile data works throughout the subway system, including deep tunnels, which is exactly where you will be re-checking Naver Map directions. Coverage nationwide is essentially total.
Should I buy a SIM at Incheon airport instead?
Incheon's SIM counters work but carry airport pricing, and after a long flight the queue is the last thing you need. An eSIM set up at home means Naver Map works from the arrivals hall.
Do I need a Korean phone number as a tourist?
Mostly no: maps, translation, T-money and payments all run on data alone. A local number only matters for some restaurant waitlist kiosks and local delivery apps, which most short-term visitors never touch.
eSIM プラン
South Korea でつながる
Naver Maps, translation apps and T-money top-ups all assume you are online, and Korea's networks are too good to waste on roaming. An eSIM gives you full-speed local data from the moment you land at Incheon.
Naver Map in a subway tunnel, Papago on a menu, and a KakaoT taxi when it rains: Korea is built for a phone that is actually online. An eSIM at Incheon is the difference between landing and living here on day one.
