Ask staff or read an official sign for the exact network name and sign-in page. Stop if the portal requests unrelated credentials, payment or device control.

TRAVELER FAQ
Answers before you leave.
Is public Wi-Fi available everywhere?
No. VISITKOREA describes broad availability in many public places but warns that reliability varies outside well-covered areas.
Can I use it for banking?
Use a connection you trust for banking, identity and password recovery. If the network operator or portal is unclear, wait or use private mobile data.
What should I save offline?
Keep the Korean public destination, route, essential ticket access, operator contacts and 112, 119 and 1330 without room numbers or access codes.
