Here is transport information. All of the information might change.

Incheon international Airport

Welcome to Incheon International Airport.
First of all I recommend you buy the T-money card.
T-money is the best public transportation card because it can be used for taxis, buses and subways.
There are two stores where you can buy the T-money card (seen in the images below).

1. Book store

This store also sells Sim cards.
They are located between Arrival C and Arrival D, next to Lotteria.
In order to buy a Sim card, you need to have your phone and your passport.
You can charge here.

Unfortunately, T-money will not provide the 10% discount shown in the advertisement above. Your limousine bus is a city limousine. Remember this.

These are the prices for a Sim card.

2. “CU” convenience store

“CU” convenience store is located between Arrival B and Arrival C, next to the Starbucks.
