Free wifi here usually means you have free access to the hotspot, some of the more popular ones are Olleh, U+zone, and T-wifi. To login in to these hotspots you either need to have purchased a code, as is the case with Olleh, or you need to have a valid korean cell phone number and alien registration number to access the free wifi. A tourist has limited options.
Places with truly free wifi:
Seoul City Center- if you find yourself walking through Seoul’s more central areas then chances are you can connect to their city wifi. But the signal is often weak and not as stable as others. Some subway stations also have this service.
