Using Smartphones in Korea in South Korea: real experience from chats

Short answer
Load Wowpass cards using KRW cash at city kiosks and always carry physical currency for local shops. Unlocked smartphones bought outright in Korea generally function internationally, though Samsung Pay may require local firmware and some carrier-financed devices may be SIM-locked.

From real experience

Financial tips for Korea: 1. Wowpass kiosks at Incheon Airport accept only KRW cash for loading; convert cash at the airport and top up the card in the city.
2. Samsung Pay/Apple Pay compatibility is limited; local Korean-firmware phones are often required for full Samsung Pay functionality. 3. Always carry some physical cash as a backup for markets and small shops.
