Arriving at Incheon Airport with a Korean Spouse: Immigration, SIM Card and Winter Tips (Our First Hour)
If you are a foreigner married to a Korean, or traveling to Korea with a Korean partner, your first hour at Incheon Airport can feel like a lot: long lines, a new phone network, freezing wind, kids and suitcases everywhere. The short answer: prepare three things before you fly: a prepaid SIM or eSIM you can pick up at the airport, warm clothes in your carry-on, and a plan for how you will get home. If you travel with a Korean spouse or with young children, the immigration part can also be much faster than you expect.
I am Korean, and my wife is Vietnamese. After living in Australia and then Vietnam, we moved to Korea with our 3-year-old child in February 2023. This is Part 1 of our arrival story: landing, immigration, getting a working phone, and the cold. In Part 2, I share how we got from the airport to my parents' home with a rental car, and how that compares with the airport bus, train and taxi.

1. Immigration: how a young child and a Korean spouse helped
Incheon is a huge, busy airport. When several international flights land at the same time, the line for foreign passport holders can get very long. The line for Korean passport holders usually moves much faster, because Koreans can use the automated immigration gates with an e-passport. You scan your passport and fingerprint, the gate opens, and you are through in a minute or two.
For us, the biggest help was our child. We were traveling with a 3-year-old, and as I remember it, the airport staff showed consideration for our family because we had a small child with us. We did not have to stand in the long foreign visitors' line for a long time. Our family went through together and came out quickly. After a long flight with a tired toddler, that kindness meant a lot, and I remember thinking how much easier this was than the arrival lines I had seen in other countries.
A few honest notes, because rules and practice can change:
- Traveling with young kids? Tell the staff. If you have a baby or a small child, let the staff at the start of the lines know. Families with young children may be guided to a faster line, but this depends on the day and the officers.
- Ask the staff first. If you are a foreign spouse arriving with your Korean partner, ask the immigration staff which line your family should use. Do not just walk into the Korean citizens' line on your own.
- Have your documents ready. The foreign spouse still needs a valid passport and the right visa. Keep your marriage-related documents handy in your carry-on, not in the checked bags.
- Later, you can use the fast gates too. After a foreign spouse gets an Alien Registration Card (ARC, 외국인등록증), they can usually register for the automated immigration gates. Check the Korea Immigration Service guidance for the current conditions.
This is what happened in our case in 2023. Immigration rules and how each line is run can change, so always follow the officers' instructions on the day.
2. The phone: get your SIM sorted before you land
In Korea, almost everything runs on your phone: maps, taxis, delivery, banking, even finding your rental car counter. Arriving without data is stressful, especially with kids.
Before we left Vietnam, we bought a 30-day prepaid SIM card online. As far as I remember, we paid in advance, chose Incheon Airport as the pickup location, and collected it at the airport counter after arrival. As soon as we came out of the arrivals hall, we put the SIM in the phone and it worked right away. From that moment, we could call the rental car company, check the map and message family.
| Option | Good for | Things to know |
|---|---|---|
| Prepaid SIM (what we used) | The first weeks or months, before you can open a regular plan | Book online before you fly and pick it up at an airport counter. Usually registered with your passport. |
| eSIM | Travelers with an eSIM-compatible phone | No pickup needed. Install it before you fly so it works as soon as you land. |
| Pocket Wi-Fi | Groups sharing one connection on a short trip | Data only, no Korean phone number. You must carry and charge the device. |
| Regular phone plan | People staying long term | For foreigners, this usually comes after the ARC. You need it for many apps that verify your identity. |
Important for foreign spouses: the prepaid SIM is great for the first weeks, but it is not the end of the story. Many Korean apps, like Coupang and banking apps, need a phone number in your own name for identity checks. In our case, my wife opened her own regular phone plan after her ARC came out. I wrote about that order in my Coupang guide.
3. The cold: nobody warned my wife enough
We landed in February. I knew Korean winters, but after many years in Australia and Vietnam, even I was shocked. When the doors opened, the wind hit us. It felt like walking into a refrigerator. My wife had never felt anything like it, and she was really cold.
The problem was simple: our warm clothes were packed in the big suitcases, and the suitcases were on the baggage belt. If you are coming from a warm country in winter, here is what I wish we had done:
- Pack one warm layer per person in your carry-on: a padded jacket, a hat and gloves. Put them on before you leave the terminal.
- Dress the kids first. Small children lose heat fast, and they will not tell you until they are already upset.
- Expect wind, not just low temperatures. Incheon is by the sea, so the wind can make it feel much colder than the number on the weather app.
- Plan a warm way home. Standing at a bus stop with kids and luggage is hard in winter. This is one reason we chose a rental car (more in Part 2).
4. Our first hour, step by step
- Landed and walked to immigration. We went through quickly as a family.
- Collected our suitcases. Grab a free airport cart. With a whole household of luggage, you will need more than one.
- Went through customs. Have your declaration ready if you carry items that need to be declared.
- Picked up the prepaid SIM at the counter in the arrivals hall and put it in the phone right away.
- Called the rental car company and went to pick up the car.
- Put on warm clothes before stepping outside. Learn from our mistake and keep them in your carry-on.
5. A checklist for foreign spouses and travelers
- ☐ Passport and the right visa for the foreign spouse
- ☐ Marriage and family documents in your carry-on, not in checked bags
- ☐ Prepaid SIM or eSIM booked before you fly
- ☐ Warm jacket, hat and gloves in the carry-on (November to March)
- ☐ Snacks, water and a small toy for the kids
- ☐ Your ride home planned: rental car, bus, train or taxi
- ☐ The address of where you are staying, written in Korean
Quick summary
- Traveling with a small child and a Korean spouse, we got through immigration quickly thanks to the staff's consideration. Ask the staff which line your family should use.
- Book a prepaid SIM or eSIM before you fly, so your phone works the moment you land.
- In winter, keep warm clothes in your carry-on. The wind at Incheon is no joke.
- The prepaid SIM is a bridge. For daily life, the foreign spouse will need a phone plan in their own name after the ARC.
