eSIM for Gangneung
Gangneung, the main city of Korea's east coast and a host city of the 2018 Winter Olympics, combines beaches, a famous coffee culture, and easy mountain access, all comfortably connected. All three carriers cover the city with fast 5G, including the Gyeongpo beach and lake, the Anmok coffee street, and the old centre. Crucially, Gangneung is now reached by KTX from Seoul through the mountains, with the line staying connected including its long tunnels. For a Gangneung trip any network is excellent, so the choice is about speed and price, with SKT the pick for the inland mountains. Navigate with KakaoMap or Naver Map, not the restricted Google Maps.
An eSIM South Korea gives you access to the same plans in Gangneung as in the rest of the country. 5 GB is generally enough for maps, messaging and social media, while video streaming and hotspot use require more data. The plans shown range from 1 to 50 GB and start at $1.90. They are fully refundable within 30 days provided the eSIM has not been used on a network at the destination. The activation link is sent by email after purchase.
Getting connected in Gangneung
Most travellers now reach Gangneung by KTX from Seoul, a fast route through the mountains that stays connected including its long tunnels, arriving at Gangneung station with strong 5G on all carriers. Toggle airplane mode once if the first attach is slow. The city is spread between the station, the beaches, and the lake, so load KakaoMap or Naver Map and KakaoTalk before exploring, as the apps make it easy to move between the coastal coffee strip, Gyeongpo, and any day trips to the Odaesan mountains or along the scenic east coast.
