Moving to South Korea often feels like stepping into the world of K-dramas, neon cityscapes, incredible food, ultra-fast internet, and one of the safest countries you can live in. Most guides focus on visas, jobs, and the language barrier, and yes, you will hear everywhere that learning Korean is important. But what many newcomers discover is that daily life comes with a set of practical challenges that aren’t usually discussed.

These are the small, sometimes frustrating details that don’t make it into official relocation checklists, the things that can turn simple tasks into confusing missions during your first months. Knowing them in advance won’t make your move perfect, but it will make it far less stressful.

Housing Is Complicated And the Deposits Are Shocking

Renting in Korea is probably the single biggest surprise for foreigners. The system is very different from most Western countries and revolves around large upfront deposits. Even for a small studio, you may need thousands of dollars in “key money.” In some cases, deposits can reach tens of thousands.

Apartments are often unfurnished and that can mean truly empty. Don’t assume basics like beds, wardrobes, or even appliances will be included. Contracts can also feel rigid, and negotiating terms isn’t always straightforward, especially without Korean language support. Utilities setup can be another puzzle. Gas, electricity, internet, and maintenance fees may all be handled separately, and instructions are rarely in English.

Understanding the rental system before arriving will save you from expensive surprises and rushed decisions.

You Need a Phone Number for Everything

In many countries, a phone number is helpful. In Korea, it’s essential. You’ll need a Korean number to register for delivery apps, banking services, online shopping, reservations, government websites, and even some messaging platforms. Identity verification through SMS codes is used constantly, and many services simply will not work without a local number tied to your identity.

There are also online restrictions that catch newcomers off guard. Some content, including certain YouTube videos, may be blocked or marked “age-restricted” unless you verify that you are over 19 using a Korean phone number. Without proper verification, you may encounter “video unavailable” messages even for content that is accessible elsewhere. To be honest some of the videos marked as restricted would seem ridiculously normal to a lot of foreigners.

Getting a SIM card at the airport can definitely help temporarily, but many full services only unlock after you receive your Alien Registration Card and switch to a long-term mobile plan. 

Tip: You can also go straight to a busy district with a lot of tourists or students like Sinchon, Hongdae or Myeongdong and find a “Woori Mobile” or “Chingu” shop. They usually offer affordable prepaid sim cards, with different options and most of the staff speaks either English, Chinese and Japanese.

Banking and Payments Work Differently

Korea is incredibly cash-light, but that doesn’t mean everything works smoothly for foreigners. Many online transactions require a Korean bank account, a Korean card, and identity verification through your phone number (which also means having an ARC). Foreign cards often fail on local websites, even when they work perfectly in stores. Setting up online banking can involve multiple apps, security programs, and verification steps that are unfamiliar to newcomers.

Once everything is set up, payments become extremely convenient, but getting to that point can take time and patience. Later on, when everything is set up on your end, you will even be able to install apps like Kakao Pay or Toss which will let you transfer and pay from your phone easily in almost every shop.

There are a few places however where cash can come in handy. The first one is Gachapon. It is originally Japanese but extremely famous in Korea. Even if most of the machines also take cards, cash is still widely used. The second place is the arcade, where you can play all kinds of games. Similarly, cards can usually be used but cash is still used a lot. The last one I can think of is the subway station, to charge your transportation card (T-money card). This type of machine even accepts coins.

Tips: In the Gachapon places and arcades, there are a few machines that allow you to split your bills (bills of 50,000 to 10,000 or 10,000 to 5,000 and 1,000). I honestly use these machines to simply break a big bill if I need it, without even playing. This way you don’t need to try asking a broken Korean to a shop owner if they could help you out. You can just enter one of these places and find one of the machines (usually red and black in arcades).

Transportation Is Great But Has Its Quirks

Public transportation in Korea is clean, efficient, and extensive. Subways and buses can take you almost anywhere, and a rechargeable transit card (T-money card) makes moving around simple. Programs such as the Climate Card offer unlimited travel within certain areas, and youth discounts may be available depending on your age and residency status. 

Navigation, however, requires adjustment. Google Maps is limited for directions, so most residents rely on local apps instead, like Naver maps or Kakao maps. The address system can also be confusing at first, especially when buildings have similar names, but you eventually get used to it.

One surprising detail for a country known for its nightlife spots (Hongdae, Itaewon, Jongno, Gangnam, Apgujeong etc.) is that the metro stops relatively early. In a city the size of Seoul, the last trains often run around midnight, which feels early compared to other global megacities. Of course late-night buses exist, but they are fewer and less convenient, so planning ahead is important if you stay out late.

Daily Life Is Convenient But Fast-Paced

Korea excels at convenience. Food delivery is available almost everywhere, often late into the night, and can be incredibly fast. You will always find something to eat 24/7! Major platforms such as Coupang, Coupang Eats, and Baedal Minjok make ordering groceries, meals, and household items effortless once you are registered.

Convenience stores (편의점) operate 24 hours a day, restaurants are abundant, and many daily needs can be solved within minutes. At the same time, life moves quickly, especially in large cities. Rush hour can be intense. Subways and buses between roughly 7:30–9:30 a.m. and 5:30–7:30 p.m. become extremely crowded, and commuting during these times can feel overwhelming at first. Popular neighborhoods, shopping districts, and transit hubs also fill up rapidly after the workday ends, particularly on Fridays.

Learning when to travel and when to avoid peak times makes a big difference in daily comfort.

Paperwork and Administration Can Be Overwhelming

Administrative processes in Korea are efficient in theory but based on my and many of my friends’ experience, inconsistent in practice. Whether you are dealing with immigration offices, local community centers, banks, or phone companies, the documents required and the procedures followed can vary depending on the staff member you encounter. It is not uncommon to be told you need one set of papers, only to discover on another day that additional documents are required. Sometimes different branches of the same institution apply rules differently. This can be frustrating, especially when language barriers are involved.

Bringing extra copies of documents, proof of address, identification, and patience is always a good strategy. When possible, asking someone experienced to accompany you can save time and confusion. 

Tips: Sometimes asking a native Korean person is not the most effective. Asking a foreigner who has been through that same process might actually be more useful, especially when dealing with immigration.

Conclusion

Moving to South Korea is an exciting and rewarding experience, but the adjustment period involves more than finding a job and learning basic phrases. The real challenges often come from everyday systems that operate differently from what you are used to, housing deposits, phone verification, transportation quirks, and administrative surprises. But I mean this is probably the same when you move to any country that is not your own.

None of these obstacles are impossible to overcome, and most become routine with time. Understanding them before you arrive simply gives you a smoother start and fewer stressful surprises. With preparation, flexibility, and a bit of patience, settling into life in Korea can be not only manageable but deeply enjoyable.

I always wished I had met someone experienced already on the plane, the first time I moved to Korea. So, I hope all these articles can help a few of you who are experiencing what I lived a few years back.
