Getting online in Korea
In South Korea the plan uses the SK Telecom and LG Uplus networks. In Seoul, Busan and other big cities coverage is excellent, and the connection is generally available on the metro. Most of the country is well covered, but in mountain areas and on remote islands the signal may be weaker.
For navigation, download Naver Map or KakaoMap, because the route guidance in Google Maps can be incomplete in Korea, particularly for walking and driving. You can order a taxi with Kakao T or with K.Ride, which is made for foreign visitors, and Uber works too. Restaurants and sights are best found with local apps, so your own data is practically a must.
At the airport you can get a local SIM or rent a wifi unit, but both mean queues, and the unit has to be returned. The eSIM is installed beforehand and the data starts on arrival. Your own number stays in the phone, and WhatsApp or KakaoTalk work over data. Hotel and cafe wifi is common, but keep your maps and taxi apps working on the street as well.
