๐ถ Free Public Wi-Fi in Korea: Where and How to Connect
Korea has extensive free public Wi-Fi run by national and local governments and telecom companies. It is a useful backup for maps and messages, but coverage and sign-in methods vary, so treat it as a supplement to mobile data rather than a replacement.

What โPublic WiFiโ means in Korea
The official Wi-Fi Free portal describes public Wi-Fi as a free internet service provided by the government, local authorities and telecom companies. Hotspots are found in public facilities, parks, transport hubs and many tourist areas.
The portal and mobile apps are available in Korean and English. You can search for hotspots by region and place name, and the operator runs a helpline for connection problems.
Connecting step by step
In Seoul, look for networks such as โPublic WiFi Freeโ, plus an encrypted โPublic WiFi Secureโ network for devices that support it. Choose the network, open your browser and follow the sign-in page that appears, which asks you to accept terms and press a connect button.
Some networks run by individual carriers ask for a Korean phone number, which visitors usually do not have. If a hotspot asks for one, move to another network instead of trying to work around it.
Cafรฉs, convenience stores and many subway stations also offer their own free Wi-Fi. Ask staff for the network name or look for a sign.
Staying safe and when to use an eSIM
Open Wi-Fi is not private. Avoid online banking, card payments and sensitive logins on it. Use a VPN if you must, and turn off automatic connection to open networks.
For navigation, taxi apps and restaurant reservations you will want reliable data everywhere, which is why most visitors combine public Wi-Fi with an eSIM or SIM card. See our eSIM guide for the options.
