3 Essentials Foreigners Need When Living in Korea

If you are a foreigner planning to live in Korea for an extended period, arranging housing, work, or school is not enough. 

Once you begin handling everyday tasks, you will quickly realize how important it is to have a Korean mobile number that supports identity verification, a reliable local banking and payment setup, and the essential apps and digital services used in daily life in Korea.

In Korea, many everyday services—including telecommunications, banking, transportation, food delivery, shopping, and reservations—are closely connected to mobile and online systems. 

Regardless of nationality, setting up these three basic foundations first can make it much easier to adjust to everyday life, even if you are not yet comfortable using Korean.

However, not every foreign resident needs exactly the same setup. 

Additional needs can vary depending on your level of Korean, length of stay, whether you are working or studying, how often you send money overseas, your dietary requirements, religious practices, and whether you are living alone or with family.

The key is not to divide preparations by nationality, but to identify the differences between your own lifestyle and the systems commonly used in Korea.

1. A Korean Mobile Number That Supports Identity Verification

A Korean mobile number is more than just a contact number

In Korea, a mobile number is not simply used for calls and text messages. It is an important part of the infrastructure used for online identity verification and access to many everyday services.

Some Korean websites and apps require mobile verification when creating an account, making a reservation, placing an online order, accessing financial services, or confirming your identity. 

Some services support international numbers, but without a Korean number, you may encounter limitations when registering, making payments, or accessing certain features.

If you plan to live in Korea long term, do not compare mobile plans based only on data allowances and monthly prices. 

It is equally important to check whether the number can be registered in your name and whether it can be used for mobile identity verification.

Short-term travel SIMs and long-term mobile numbers serve different purposes

For a short trip, a data-focused SIM or eSIM may be enough. However, if you are staying in Korea long term for work, study, family reasons, or another purpose, you may need additional features.

When choosing a mobile service for a long-term stay, check the following:

• Whether you can reliably receive calls and text messages in Korea

• Whether the number can be registered under your name

• Whether it can be used for online identity verification

• Whether you need to keep the number active when temporarily outside Korea

• Whether the data allowance and monthly cost suit your lifestyle

• Whether customer support is available in English or other languages

Rather than simply choosing the cheapest option, it is more important to confirm that the plan provides the communication and verification features you will actually need in Korea.

If Korean-language support is difficult, check for multilingual customer service

Mobile plans may look similar at first, but contract periods, cancellation terms, additional charges, and data restrictions can vary.

If you are not comfortable reviewing a contract in Korean, check whether customer service is available in English or another language you understand. 

For long-term contracts in particular, make sure you understand not only the monthly fee but also cancellation conditions and any additional charges before signing up.

A simple plan that matches your length of stay and actual data usage is often easier to manage than a complicated package with features you may not need.

2. A Korean Bank Account and Reliable Payment Method

Relying only on foreign cards can be inconvenient for long-term living

International credit cards issued overseas are accepted in many places in Korea. However, relying on a foreign card for every financial activity can become inconvenient during a long-term stay.

Many everyday tasks become easier with a Korean bank account, including paying rent or building management fees, receiving a salary, transferring money to other people, making online payments, and paying mobile phone or utility bills.

Depending on your card issuer, continuously using an overseas card may also result in foreign transaction fees, while exchange-rate fluctuations can affect how much you actually spend.

For long-term residents, it is therefore useful to establish a local financial setup for everyday life in Korea, rather than relying exclusively on payment methods designed for travel.

A Korean bank account can expand your access to everyday services

A Korean bank account is not simply a place to keep your money. It serves as basic financial infrastructure for many everyday activities in Korea.

Having a Korean account can make it easier to:

• Receive your salary

• Transfer rent and building management fees

• Send money to friends or other individuals

• Pay for online purchases

• Set up automatic payments for mobile and utility bills

• Use domestic payment services

However, account-opening requirements and available services for foreign residents can vary depending on the bank, immigration status, length of stay, and required documentation.

Before visiting a bank, check which identification and residency-related documents you need. If possible, it may also help to find a branch or service desk that offers support in a language you understand.

If you regularly transfer money overseas, consider more than domestic banking

If you expect to send money to family in your home country or regularly receive money from abroad, international transfers should also be part of your decision when choosing a bank or financial service.

Do not look only at the transfer fee. Exchange rates, intermediary fees, supported destination countries, and transfer limits can also affect the final cost.

If you make international transfers regularly, even a small difference in fees can add up over time.

For this reason, when choosing a Korean bank account, it is practical to consider both domestic payments and international transfers.

3. Essential Apps and Digital Services for Daily Life in Korea

In Korea, a smartphone is an everyday life tool

In Korea, a smartphone is much more than a communication device. Maps, transportation, food delivery, shopping, banking, reservations, and many other everyday services are closely connected to mobile platforms.

The challenge is that apps you commonly used in your home country may not always be the most convenient options in Korea.

Instead of searching for an app every time a new need comes up, it is helpful to understand in advance which services are commonly used in Korea for different parts of daily life.

Start with maps and public transportation apps

For foreigners beginning life in Korea, map and transportation apps are among the most useful services to set up first.

In Seoul and many other cities, buses and subways are an important part of daily transportation. 

Apps that provide real-time transit information, transfer routes, and subway exit locations can make getting around significantly easier.

Local mapping services such as Naver Map and KakaoMap are widely used in Korea.

Try searching in advance for places you are likely to visit regularly, such as your home, school, workplace, or hospital, and choose the service that is easiest for you to use.

Messaging apps should also reflect how communication works in Korea

KakaoTalk is widely used in Korea not only for personal conversations, but also in workplaces, schools, clubs, communities, and other group settings.

You can continue using WhatsApp, iMessage, Telegram, Messenger, or any other messaging service you already use. However, having KakaoTalk as well can make it easier to build new personal and professional connections in Korea.

If you prefer to keep your work and personal life separate, it is worth reviewing notification settings, profile visibility, and friend-add settings from the beginning.

Food delivery and shopping apps can come after the basics are in place

Korea has highly developed food delivery and online shopping services, but you do not need to install every app as soon as you arrive.

A practical order is:

1. Maps and public transportation

2. Messaging

3. Banking and payments

4. Food delivery

5. Online shopping

Some services work more smoothly when you already have a Korean mobile number or domestic payment method.

For this reason, setting up your mobile and financial services first, then adding the apps you actually need, is usually the most efficient approach.

Additional Things to Consider Based on Your Personal Situation

If you are not comfortable with Korean, treat language support as part of your essential setup

If you do not speak Korean well, having a translation app alone may not always be enough.

It is particularly important to understand information accurately when dealing with banks, hospitals, mobile carriers, real estate agencies, and government offices, where contracts, payments, or personal information may be involved.

The following can be useful:

• Translation apps with camera translation features

• Services offering English or multilingual support

• Banks or mobile carriers with foreign-language customer service

• Access to interpretation support when necessary

• A saved record of frequently used Korean addresses and personal information

Most importantly, avoid signing or agreeing to contracts, mobile plans, or other paid services if you do not fully understand the terms.

If you make frequent international transfers or overseas payments, manage exchange rates and fees carefully

If you earn income in Korea and regularly send money to your home country or support family members abroad, exchange rates and transfer fees may matter more to you than they do to someone who uses only domestic banking services.

Likewise, if you continue funding your Korean living expenses through accounts or cards in another country, currency conversion and foreign transaction fees can occur repeatedly.

Depending on your situation, it may be more efficient to use a combination of a Korean account, overseas cards, and international money transfer services.

The important factor is not where you come from, but how often you need to make cross-border financial transactions.

If you have specific dietary or religious requirements, consider your neighborhood as well

If you follow a vegetarian, vegan, or halal diet, or have specific food allergies, it is a good idea to check actual ingredients and preparation methods rather than relying only on menu names.

Korean dishes may include multiple ingredients in broths, sauces, and seasonings, so it can be safer to ask the restaurant directly when necessary.

If you regularly need access to a religious facility or a particular type of grocery store, you may also want to consider proximity to these places when choosing where to live, rather than looking only at the distance to your workplace or school.

If something is going to be a regular part of your life, considering it when choosing your neighborhood can make day-to-day living much easier.

If you are living with family, there are more factors to consider

Living in Korea alone requires a different level of preparation from moving with a spouse, children, or other family members.

Families may need to consider hospitals, schools or childcare, housing space, transportation, and mobile and financial services for multiple household members.

If you have children, for example, it may be more practical to consider the distance to schools or educational facilities, public transportation, and everyday amenities rather than focusing only on the size or monthly cost of a home.

Ultimately, preparing for life in Korea depends less on nationality and more on who you are living with and how you plan to live.

What Should Foreigners Set Up First When Starting Life in Korea?

Start with your mobile phone and internet access

Immediately after arriving in Korea, reliable internet access and a working means of communication should be among your first priorities.

Many essential early tasks—searching maps, translating information, checking transportation, and communicating with a landlord or employer—depend heavily on your phone.

If you are staying long term, it is more efficient to choose a mobile setup that can eventually support identity verification rather than relying only on a SIM that provides internet access.

Set up banking and payments next

Once your mobile service and residency-related documents are ready, you can look for a bank account and payment method that fit your circumstances.

Do not think only about receiving a salary or paying for everyday expenses. Consider the financial activities you are likely to use in practice, including rent, utilities, online shopping, and international transfers.

Banks and financial services may have different document requirements and conditions for foreign residents, so it is best to check these in advance.

Then add the apps that fit your lifestyle

Once your mobile and financial setup is in place, you can gradually add map, transportation, messaging, food delivery, and shopping services.

Rather than installing many apps at once, it is usually easier to become familiar with the services you actually use most often.

The basic structure of settling into life in Korea is relatively simple: Korean mobile number → banking and payment methods → essential everyday apps. Once these foundations are in place, you can add other services based on your personal needs.

What Foreigners Need Depends More on Lifestyle Than Nationality

Even people from the same country may need completely different things

When preparing to live in Korea, it is difficult to determine what someone needs based only on their country or region of origin.

Two people from the same country may have entirely different circumstances. One may work for a Korean company and receive a local salary, while another may be a short-term student. One may frequently transfer money abroad, while another may use only domestic financial services.

The level of support needed will also be very different for someone who speaks Korean fluently and someone who does not speak Korean at all.

For this reason, instead of dividing foreign residents by nationality or region, it is more accurate to consider the purpose of your stay, language needs, financial habits, dietary requirements, family situation, and lifestyle.

Identifying your own needs first can make adjusting much easier

Before coming to Korea, it can help to answer a few practical questions.

How long will you stay in Korea? Will you receive a salary in Korea? How often will you send money overseas? Are you comfortable handling contracts and customer service in Korean? Do you have specific dietary or religious requirements? Will you be living with family?

The clearer your answers are, the easier it becomes to avoid paying for services you do not need and to focus first on the infrastructure that matters to your daily life.

The most important part of moving to Korea is not bringing a large number of belongings. 

The priority is to establish a mobile setup for communication and identity verification, reliable financial tools, and a digital environment that supports transportation and communication.

Once these basics are in place, you can add support for your own language needs, international transfers, dietary requirements, religious practices, and family situation.

 Taking this approach can make the transition to everyday life in Korea much more stable and manageable.

Frequently Asked Questions

Question 1

Q. Do foreigners living in Korea long term really need a Korean mobile number?

A. For a short trip, an international number and a data eSIM may be enough. For long-term residents, however, having a Korean number is much more convenient because some account registrations, reservations, financial services, and online platforms may require mobile identity verification.

Question 2

Q. Can foreigners live in Korea using only overseas cards without opening a Korean bank account?

A. Foreign cards are accepted in many places, but a Korean bank account makes it easier to handle rent, salary payments, bank transfers, and automatic bill payments during a long-term stay. If you frequently send money overseas, it is also worth comparing international transfer fees and exchange rates alongside domestic banking convenience.

Question 3

Q. Do preparations for living in Korea depend on a foreigner's nationality?

A. Nationality itself is usually less important than factors such as length of stay, Korean-language ability, financial habits, dietary requirements, religious needs, and family situation. It is more practical to decide what you need based on your actual living circumstances rather than your country of origin.
