eSIM for Daegu
Daegu, a large inland city in Korea's southeast, is a comfortably connected metropolis on the KTX line between Seoul and Busan. Known for its textile heritage, its lively markets, and the surrounding mountains, Daegu has fast 5G across the centre on all three carriers, including the subway. The nearby Palgongsan mountain with its cable car and temples is where the only mild terrain consideration appears, and even there coverage holds well on the trails with SKT strongest. For the city any network is excellent, so the choice is about speed and price. As across Korea, navigate with KakaoMap or Naver Map rather than the restricted Google Maps.
An eSIM South Korea gives you access to the same plans in Daegu 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 Daegu
Most travellers reach Daegu by KTX from Seoul or Busan, staying connected the whole high-speed route, arriving at Dongdaegu station with strong 5G on all carriers. If you fly into the city's airport, the wifi completes any eSIM activation. The subway from the station into the centre stays connected in its tunnels. Toggle airplane mode once if the first attach is slow. Before exploring, load KakaoMap or Naver Map and KakaoTalk, since the markets, the centre, and the mountain day trips are all easier to navigate with the apps Korea actually uses for transit and walking directions.

Coverage in Daegu
Coverage across Daegu is comprehensive on all three networks with strong 5G.

The Daegu Metro carries fast signal in tunnels and stations throughout. The hillside districts and the herbal medicine market are well connected. The main terrain feature is Palgongsan, the mountain on the city's edge with its cable car, Donghwasa temple, and the Gatbawi stone Buddha, where coverage holds on the trails and at the temples, with SKT the strongest network toward the higher and more remote sections.

How much data in Daegu
Daegu rewards data like the rest of Korea, with the city running on navigation, transit, translation, and KakaoTalk. Budget 1 to 2GB per day for active use, more if you stream on the KTX. Many Korea eSIMs offer unlimited or generous daily allowances resetting every 24 hours. The markets, the mural street, and the mountain temples are the photo highlights, so keep cloud backup on wifi-only at your accommodation.
