Does the same eSIM work outside Seoul, like a day trip to the DMZ or Nami Island?

Yes. It's a single national South Korea plan, so the very same eSIM works on the border tours near the DMZ, out at Nami Island, and anywhere else you travel in the country - no need to buy a separate plan.

Can I set up the Seoul eSIM before I fly?

Yes. Install it before departure and it activates when you connect at Incheon Airport, so you can order a Kakao T taxi or catch the AREX train the moment you land without hunting for airport Wi-Fi.

Good to know in Seoul

Google Maps can't give walking or driving directions in South Korea, so download Naver Map or KakaoMap once you're online - both are in English and far more accurate for Seoul's subway and side streets.

Two simple ways to buy

Seoul eSIM plans: unlimited, or by the GB.

Every Seoul eSIM from My Holiday SIM is one of two straightforward types. Pick whichever fits how you travel in Seoul — you can always top up or switch on your next trip.

Traveller streaming and browsing freely on an unlimited-data travel eSIM

Unlimited plans

High-speed data, nothing to count

Priced per day — the longer you stay, the better the daily rate. Ideal for streaming, hotspot and longer trips where you'd rather not watch a data meter. A fair-use policy keeps speeds fast for everyone; see each plan for the detail.

Best for streaming, video calls & hotspot
Great for longer or open-ended trips
One price per day — no GB anxiety

By-the-GB plans

3GB10GB20GB

A set bundle, brilliant value

A fixed data allowance (say 3 GB or 10 GB) valid for your travel days. The best-value pick for lighter trips built around maps, messaging and a bit of browsing. Running low? Top up in a couple of taps — nothing to reinstall.

Best value for lighter, shorter trips

Plan your data

How much data do you need in Seoul?

A rough, honest guide to sizing your Seoul eSIM so you're not guessing. Most travellers in Seoul are comfortable on 3–5 GB a week — heavy streamers just go Unlimited.

Maps, messaging & email

Google Maps, WhatsApp, email and the odd search. Plenty for a city break where you mostly need directions.

Seoul eSIM: your local data guide.

Seoul moves fast, and so should your phone - you'll want live directions the moment you step off the AREX train at Seoul Station. A Seoul eSIM keeps you online for navigating the subway to Gyeongbokgung Palace, queueing for street food in Myeongdong, and finding the right exit among Hongdae's maze of clubs and cafes.

One eSIM for Seoul and all of South Korea. It's the national South Korea eSIM — from $3.14/day with unlimited data, working the same in Seoul as it does the moment you leave it.

Landing at Incheon International Airport (ICN)?

Install the QR at home, then switch the eSIM on as you taxi in — you're online before you reach the arrivals hall.

On the ground

Where you'll lean on data in Seoul.

Myeongdong

Lean on data for live menus, tax-free store hours and currency maths as you graze the street-food stalls.

Hongdae

You'll want a solid signal to split bills, stream buskers and pin meeting spots across the late-night bars.

Gangnam

Steady 5G keeps maps flowing between COEX Mall, the vast underground shopping and the glass business towers.

Bukchon Hanok Village

Follow live walking routes and respect quiet-hours signage while navigating the narrow lanes of traditional hanok.

The practical bit

Getting around Seoul on your eSIM.

Apps you'll want online in Seoul

Kakao T— Korea's main taxi-hailing app - book cabs, black cars and airport transfers across Seoul.
Naver Map— The most accurate navigation and transit app in Korea, with English and live subway times.
Subway Korea— Plans Seoul metro routes with real-time arrivals, fares and the fastest transfer carriages.
Papago— Naver's translator for menus, signs and conversations - far better than Google for Korean.

How long to stay in Seoul

Most travellers spend three to five days in Seoul, enough for the palaces, a couple of neighbourhoods like Hongdae and Gangnam, and a day trip out to the DMZ.

How much data for Seoul

For a few days in Seoul, a balanced 3-5 GB comfortably covers maps, translation and social sharing; pick Unlimited if you'll stream on the subway or tether a laptop from cafes.

Coverage in Seoul

Seoul has some of the world's best mobile coverage - fast 5G blankets the city, subway and underground malls. Signal only realistically thins on remote hiking trails up Bukhansan on the outskirts.

Peace of mind

Your Seoul eSIM: data-only, zero bill shock.

Your Seoul eSIM handles the internet while you travel. Your home number stays exactly where it is — no surprise roaming charges in Seoul, no swapping your real SIM out.

Keep your number & WhatsApp

The eSIM is data-only and runs alongside your home SIM. Your number, iMessage and WhatsApp keep working exactly as they do at home.

No roaming bills, ever

Turn data roaming OFF on your home SIM and ON for the eSIM. You pay once, up front — no overage, no metered surprises, no bill waiting when you land home.

One thing worth knowing

Because it's data-only, the eSIM can't receive bank verification (OTP) text codes — those still go to your home number. Keep it reachable on Wi-Fi calling, or use app-based codes.
