South Korea travel tips
- Google Maps navigation has long been limited in South Korea, and although that is changing, it may not give full walking and driving directions yet. Check it works before you rely on it, and have a local map app such as Naver Map or KakaoMap ready as a backup. Download them before you leave Australia. They work best with mobile data.
- Food and K-culture trips usually mean a lot of searching, translating menus, booking restaurants and posting photos and video, so plan on medium use or more. A typical trip covers Seoul plus Busan or Jeju, so check the provider's coverage map if you're heading somewhere more remote.
- Most travel eSIMs are data-only and won't give you a Korean phone number. Some local services and bookings ask for one, so check ahead if something you've booked needs it, and keep your Australian SIM on for SMS codes with its data roaming off.
- Install the eSIM at home on Wi-Fi before you fly, so it's ready when you land at Incheon or Gimhae.
