Public transportation in Korea is incredibly convenient, but there are a few rules that might be unfamiliar to newcomers. The most important is the 'Transfer Discount' system. You must tag your transportation card on the reader whenever you get off a bus or exit a subway station to receive a discount on your next ride. Also, if you head the wrong way in the subway and exit the turnstile only to re-enter, you may be charged twice, so check the signs carefully. Lastly, remember that eating food inside buses is prohibited. 

✅ For a smooth journey, having access to real-time traffic information is essential. Running out of data while checking subway maps or searching for directions can be a stressful experience. Having a reliable South Korea SIM card from the start allows you to navigate with peace of mind.
