10 Essential Things Every Visitor Should Know on Day One

You may have already read about Gyeongbokgung Palace, K-Pop, Korean food, and all the must-see attractions before coming to Korea.

But the moment you arrive at Incheon International Airport, a completely different set of questions begins.

“How do I get from the airport to Seoul?”
“Which transportation card should I use?”
“Will my foreign credit card work?”
“Can I rely on Google Maps?”
“How do I call a taxi?”
“What should I do in an emergency?”

Korea is an incredibly convenient country once you understand how things work.

The problem is that many things Koreans take for granted may not be obvious to first-time visitors.

So Korea101Guide has prepared the 10 most important things every foreign visitor should know on their first day in Korea.

1. Get Connected to the Internet First

In Korea, your smartphone is much more than a phone.

You will probably use it for:

• Maps
• Translation
• Public transportation
• Restaurant searches
• Taxi services
• Reservations
• Travel information

That is why one of the first things you should do after arriving is make sure you have a reliable mobile data connection.

Your main options are:

eSIM
SIM card
Portable Wi-Fi

If your phone supports eSIM, setting it up before you arrive can be one of the easiest options.

Korea101 Tip

Before leaving the airport, turn off the airport Wi-Fi and check whether your mobile data actually works.

Many travelers think everything is fine while connected to airport Wi-Fi, only to discover later that their SIM or eSIM is not working properly.

2. Don’t Rely Only on Google Maps

This surprises many first-time visitors.

Google Maps may be your go-to navigation app in most countries, but in Korea, local map apps are often much more useful.

The two major options are:

Naver Map
KakaoMap

They are particularly useful for:

• Subway routes
• Bus arrival times
• Walking directions
• Restaurants
• Shops
• Local addresses

Korea101 Tip

Before arriving in Korea, consider installing at least these three types of apps:

Naver Map + Papago + a taxi app

This combination alone can make traveling around Korea much easier.

3. Get a T-money Transportation Card

If you plan to use buses and subways regularly, a transportation card will make your trip much more convenient.

The best-known option is T-money.

You can use it on many subway and bus systems throughout Korea, and it can also be used at some convenience stores.

Simply tap your card when entering and exiting public transportation.

Important Tip for Foreign Visitors

It is a good idea to carry some Korean won in cash, especially when you first arrive.

Some transportation card purchases or top-ups may still require cash depending on where you are.

A small amount of cash can save you unnecessary trouble on your first day.

4. If You’re Exploring Seoul, Check the Climate Card

If you plan to travel around Seoul extensively using public transportation, you may also want to compare T-money with Seoul’s Climate Card.

Depending on your travel schedule and the type of pass available, an unlimited or short-term transportation pass may be more economical.

A simple way to think about it is:

Occasional transportation → T-money

Heavy sightseeing around Seoul → Compare unlimited travel passes

The best option depends on how much you plan to move around.

5. Credit Cards Are Everywhere — But Carry Some Cash

Korea is highly card-friendly.

You can pay by card at most:

• Hotels
• Department stores
• Cafés
• Convenience stores
• Restaurants
• Supermarkets

Major foreign-issued credit cards are widely accepted at many businesses.

However, don’t assume that Korea is completely cashless.

Cash can still be useful for:

• Traditional markets
• Small businesses
• Certain transportation card services
• Unexpected situations

Korea101 Recommendation

The safest combination is:

International credit card + small amount of Korean cash + transportation card

With these three, you will be prepared for most everyday payment situations.

6. You Don’t Always Need a Taxi from Incheon Airport

There are several ways to travel from Incheon International Airport to Seoul.

The most common options include:

• AREX Airport Railroad
• Airport limousine bus
• Taxi
• International taxi services

If you have a lot of luggage or are traveling with several people, a taxi may be convenient.

But if you are traveling alone and your accommodation is near a subway station, the airport railroad can be simple and economical.

The most expensive option is not necessarily the best option.

Choose based on where your hotel is located.

7. Korean Convenience Stores Are Mini Life-Savers

Convenience stores in Korea are much more useful than many visitors expect.

You’ll see brands such as:

CU
GS25
7-Eleven
emart24

almost everywhere.

They offer much more than snacks and drinks.

You can find:

• Quick meals
• Water
• Coffee
• Everyday toiletries
• Basic travel necessities
• ATMs at some locations
• Transportation-related services at some stores

If you suddenly need something late at night, check the nearest convenience store first.

For many travelers, Korean convenience stores become an essential part of everyday life.

---

8. Restaurant Service Works a Little Differently

When you visit a Korean restaurant for the first time, you may notice that the staff do not always come to your table immediately.

Don’t worry.

Many restaurants have a call button on the table.

Simply press it when you need assistance.

Ordering systems also vary.

At some restaurants you:

• Order directly from the staff
• Use a tablet at the table
• Use a self-service kiosk
• Pay before eating
• Pay after eating

If you are unsure, watch what other customers are doing.

You’ll figure it out quickly.

9. Remember These Two Emergency Numbers

These may be the two most important numbers to know while traveling in Korea.

112 — Police

119 — Fire and medical emergencies

Hopefully, you will never need them.

But in an emergency, you may not have time to search online.

Save them in your phone.

10. Welcome to Korea’s Famous “Ppalli-Ppalli” Culture

One thing you will probably notice very quickly in Korea is speed.

Everything seems fast.

People walk quickly.

Food arrives quickly.

Internet connections are fast.

Deliveries are fast.

Services are often fast.

Koreans sometimes describe this culture with the expression:

“Ppalli-ppalli” (빨리빨리)

which literally means:

“Quickly, quickly.”

At first, the pace may feel intense.

But after a few days, you may begin to appreciate how much convenience this fast-moving culture creates.

And remember:

You don’t have to move at everyone else’s speed.

Enjoy Korea at your own pace.
