Is South Gyeongsang covered by the same eSIM as Busan?

Yes. South Gyeongsang wraps around Busan and runs on the same national networks — SK Telecom, KT and LG U+. One eSIM covers Changwon, Tongyeong, Jinju and Busan itself with no switching.

Will my eSIM work at Haeinsa temple?

Around the Haeinsa complex and car park you'll have usable data, but it fades on the Gayasan mountain trails above the temple. Download offline maps if you plan to hike beyond the main buildings.

Best time to visit South Gyeongsang

Autumn (October) for calm seas and the Jinju Lantern Festival, or late spring (May) when the coast and island gardens are in full bloom.

Across the region

Where you'll lean on data in South Gyeongsang.

Tongyeong

Tongyeong's harbour, Dongpirang murals and cable car run on strong coastal 5G; signal dips on the outer Hallyeo ferry islands.

Geoje

Geoje's Windy Hill, Oedo island gardens and beaches carry dependable data, thinning slightly on the smaller offshore isles.

Jinju

Jinju's fortress, Namgang river and lantern-festival grounds sit on solid city 5G, so uploads and maps stay quick.

Haeinsa (Gayasan)

At Haeinsa temple and Gayasan National Park, data holds near the complex but fades on the mountain trails above.
