Korea has many different things to offer and I’m sure you are going to find lots of exciting things to do.

But first things first, before starting planning all the fun stuff from the trip lets quickly do a checklist of the serious most important things to know before traveling to South Korea so your trip is smooth and stress free.

1. Sort Your Entry Visa (K-ETA & visa types)

As you might already know, the requirements for entering Korea depend on your nationality, and they can change from time to time. So you have to keep yourself updated with that info from official pages. But in general, you’ll need to find out which of these types applies to you:

• Tourist Visa: which you obtain from a Korean embassy in your country of residence.
• Q-Code: an online form for a smoother arrival process.
• K-ETA: which is an online travel authorization to be able to board the plane (starts in 2026 allegedly).
• No visa at all.
  

It’s really important to check what is required for your specific passport before traveling to South Korea. And the best way to do this is to do your research and visit the official website of the Korean Immigration Service. A quick search will give you the most accurate and updated information.

2. Stay Connected in Korea: SIM Card or eSIM?

Before getting to Korea, you have to decide what option you’re going to choose to stay connected to Wi-Fi everywhere you go. You have the option of getting a normal SIM card or an eSIM. Here’s a breakdown of the pros and cons to help you choose.

Physical SIM Card

· Pros: Universally compatible, easy to swap between phones. You get a local number which can be useful for many apps or to make local phone calls (for food delivery for example). You can often get a more reasonable price for data.

· Cons: You need to find a physical store and go buy it in the airport or a store in the city.

eSIM (Digital SIM)

· Pros: You can buy it online before your trip from providers like Holafly or Airalo and activate it instantly upon arrival. No physical card is needed, and you can find unlimited data deals easily.

· Cons: It’s more expensive most of the time. You don’t get a local phone number, and sometimes the reception can be weaker.

Tip: Popular eSIM options include Holafly and Airalo, which you can purchase before the trip and activate right when you land. 

How to Get a SIM Card

At Incheon Airport:

This is the most convenient way to find a physical SIM. When you exit arrivals in Terminal 1, you’ll find several SIM card counters all in one place. They sell the main providers in Korea, which are KT, SK Telecom, and LG U+. They all have the same pricing, but each one has a freebie to help you make your mind up. We chose KT because they gave a free transportation card at the time, but choose whichever you prefer.

Other Spots Around the City:

You can look for carriers’ official stores around the city. Look for the stores of SK Telecom, KT, or LG U+ in tourist districts like Myeongdong, Hongdae, and Insadong. The staff there can show you your options and handle the entire activation process for you right there in the store.

If you’re looking for a more basic and even cheaper option, you can find prepaid data-only SIMs at convenience stores like CU, GS25, or 7-Eleven. But keep in mind that the options are more limited, and you will likely need to manage the activation yourself.

How to Get an eSIM

This is a great choice if you want to get online easily. The best thing is you can buy it online from companies like Holafly or Airalo before your trip even starts. And you can turn it on as soon as you arrive in Korea. It is very easy and you don’t need a physical card.

Just remember the cons we mentioned before: an eSIM is often more expensive, doesn’t come with a local phone number, and sometimes the connection might not be as strong. But for pure convenience, it’s a really good choice.

3. Cash is not king but still handy

It’s always a good idea to carry with you some cash because even though credit cards are widely accepted in most stores and restaurants, cash is essential if you want to buy food in street food markets, small family-owned shops or groceries, and for a really important thing: for reloading your transportation card at convenience stores. Which leads us to the next point…

Tip: get a Revolut card to get the best conversion rates on local currency on ATMs all around the world!

4. Your transportation card: T-money

This is the transportation card that you are going to need to move around with any public transport in Korea: metro or bus. You can buy them in convenience stores like CU, GS25 or 7-Eleven. There’s some stores like this even in the airport and you can buy it right there. As mentioned previously for some reason you have to use cash to charge money on the card so you have to exchange money or go to the ATM before buying this card.

Tip: You can also use these cards to pay in convenience stores, vending machines and even some restaurants!

5. How to get into Seoul from the airport

You’ve got a few options to get to the city from the airport. The most popular is called AREX which stands for Airport Railroad Express. This is the train line that connects the airport with the city center.

Other options that are possible but slower depending on traffic are: Bus limousine, Taxi or Kakao T which is the Korean Uber app.

6. Download These Lifesaver Apps

There’s a few app switches that you will need to do while traveling in Korea because the apps that you might be used to use every day might not be reliable to use there like for example Google Maps (I know what a bummer). So you will need to download these apps instead:

• Naver Map: this is the best navigation app in Korea for foreigners that have no understanding of the Korean language. It’s the only app with full English support and is accurate for walking, driving, and using public transport.
• Papago: The best translation app for Korean.
• Kakao T: the Uber app swap of Korea. You’ll need it if you prefer taking taxis instead of using public transport.
• Coupang Eats: the best English-translated Food Delivery app. Mostly all menus are in English so that’s handy.

7. Learn a few Korean basic phrases

Learning Korean — locals appreciate the effort immensely. Master these three:

• Annyeonghaseyo (안녕하세요): Hello.
• Kamsahamnida (감사합니다): Thank you.
• Jogiyo (저기요): “Excuse me” to get someone’s attention.

8. Self-Service is Common

In many casual eateries, you order at a counter and get a number. At some BBQ places, you might even cook the meat yourself! Also, in many cafes and restaurants, you’ll grab your own water and cups from a dispenser. Don’t wait for a server to bring it to you. In many restaurants, you’ll get cups and a water dispenser to serve yourself.

Some places have QR code ordering or ticket machines, which can be intimidating but are easy once you get the hang of it. Papago’s image translate is your friend here.

9. Convenience stores

Convenience stores in South Korea are more than just quick stops — you’ll probably use them every day while traveling. The main chains are CU, GS25, and 7-Eleven, and they are open 24/7.

You’ll find ready-to-eat meals, triangle kimbap, instant ramen, snacks, drinks, and surprisingly good coffee, all at affordable prices. Most stores have microwaves and hot water, so you can eat right there.

They’re also very useful for travelers because you can top up your T-money card, buy water for day trips, and pay easily with card or cash.

10. Beware the Spiciness

Korean food is amazing, but it can be spicier than expected, even when a dish doesn’t look red and spicy. Many meals include gochujang, a red chili paste that adds that hidden heat.

If you’re sensitive to spice:

• Ask for “not spicy” or say An mae-wo-yo (안 매워요)
• Start with safer dishes like kimbap, bulgogi, or japchae

What locals consider mild can still be spicy for first time visitors to South Korea so keep that in mind and always have a drink nearby, just in case

Conclusion

You have the option to go into the desert by 4×4 or by camel, but if you choose the camel make sure you go with an operator that treats them well, because we saw some that were clearly over worked 🙁 so choose camel rides carefully to ensure the animals are treated well.
