The simplest eSIM Korea option is one you install before you fly: it connects to KT or SK Telecom 5G when you land at Incheon, needs no passport, and costs $2.80 per GB with no expiry. South Korea registers every local SIM against a passport, and since July 2026 new lines also need facial recognition or a mobile ID check.
This page covers eSIM Korea basics: what it costs, which networks you get, the subway and KTX, the apps that work best for visitors, ID rules, setup, and how it compares with a Korean tourist SIM. The same balance also works in Japan.
How much does eSIM Korea data cost?
$2.80 per GB, billed per MB from a USD balance that never expires; a one-time $5 setup fee applies to a new eSIM.
One rate: $2.80/GB, metered per MB against a prepaid USD balance — this is how our no-KYC eSIM works, and the balance never expires. No daily passes, no expiring bundles, no throttling tiers - unused credit stays on your eSIM forever and works in the next country you visit.
| Top-up | Data in South Korea | Effective rate |
|---|---|---|
| $5.00 | ≈ 1.8 GB | $2.80/GB |
| $10.00 | ≈ 3.6 GB | $2.80/GB |
| $20.00 | ≈ 7.1 GB | $2.80/GB |
| $50.00 | ≈ 17.9 GB | $2.80/GB |
A one-time $5 setup fee applies to a brand-new eSIM; top-ups to an existing eSIM carry no fee. Rates are pay-as-you-go, so light days cost cents and heavy days just draw down the balance faster.
What should you look for in an eSIM Korea plan?
Check the networks, the price per GB, expiry, hotspot, ID requirements, onward coverage, and whether you need a Korean number.
- Networks. Look for access to KT or SK Telecom. Anon eSIM uses both, and your phone picks the stronger signal.
- Pricing model. Day-based bundles charge for time; per-GB billing charges for what you use. Anon eSIM is $2.80/GB.
- Expiry. Many bundles and tourist SIMs expire after 5–30 days. An Anon eSIM balance never expires.
- Hotspot. Some plans limit tethering. Anon eSIM includes it at full speed.
- ID and account. Korean SIMs need a passport and, since 2026, extra identity checks. Anon eSIM needs no ID and no account.
- Onward trips. Check that Japan and your other stops are covered on the same eSIM.
- A Korean number. Anon eSIM is data-only. If you need a 010 number for delivery or banking apps, a passport-registered tourist SIM is the practical choice.
What is arriving at Incheon like?
Incheon's carrier counters are quick but check your passport; a pre-installed eSIM is on 5G before you reach the AREX train.
Incheon has SK Telecom, KT and LG U+ roaming centres in arrivals that sell tourist SIMs and eSIMs, and they verify your passport before activation. Lines are quick by global standards, but a pre-installed Anon eSIM is already on 5G as you walk to the AREX train into Seoul.
How much data does a Korea trip use?
Most visitors use 400–700 MB a day, so a week is about 3–5 GB.
One week in Seoul and a day in Busan: Naver Map, KakaoTalk, translation, photos
7 days · 3–5 GB · $ 8.40–$14.00 at $2.80/GB
Korea's fast networks make it easy to use more data than you planned: maps, translation and video all load instantly. Most visitors use 400–700 MB a day, so a week is about 3–5 GB, or $8.40–$14.00 at $2.80/GB. Cafés and hotels almost always have fast Wi-Fi.
Which networks and speeds do you get in Korea?
KT and SK Telecom, with 5G in the cities, LTE almost everywhere else, and full subway coverage.
Anon eSIM connects through roaming agreements with KT and SK Telecom, with 5G typically available to roamers. Your phone picks the strongest partner signal automatically and re-selects as you move - there is nothing to configure.
Some of the fastest mobile data on Earth, underground metro included. No practical coverage gaps.
KT and SK Telecom run some of the fastest mobile networks in the world, with 5G across Seoul, Busan and most cities and LTE nearly everywhere else. The Seoul and Busan subways, including tunnels, are covered. Coverage thins only in remote mountain areas and on some smaller islands.
LG U+ isn't one of Anon eSIM's listed partners here, so your phone connects to KT or SK Telecom.
The APN is provisioned automatically with the eSIM profile. You do not need to enter APN settings manually on iOS or Android - the only switch you must flip is Data Roaming: ON for the Anon eSIM line, because the service is technically a roaming profile everywhere it operates.

Does it work on the KTX and Seoul subway?
Yes. KT and SK Telecom cover subway tunnels in Seoul and Busan and most of the KTX network, with brief drops in some long tunnels.
Subway stations and tunnels in Seoul and Busan are covered, so maps and messaging keep working underground. The KTX between Seoul and Busan is covered for most of the route, with short drops in some longer tunnels.
Coverage on the AREX airport railway means you can check directions to your hotel on the way into Seoul.
How do you set up your Korea eSIM?
Before you buy, check that your phone supports eSIM and isn't locked to a carrier on our compatible devices page. For a full walkthrough, see how to use an eSIM for international travel.

Do you need a passport for an eSIM in Korea?
Not for a roaming eSIM: Korean rules require ID for Korean SIMs, but a visitor's foreign profile isn't a Korean subscription.
Korean carriers must verify identity for every new line, and visitors buy tourist SIMs with their passport. From July 2026, activation rules tightened further, adding facial recognition or a mobile ID check and stricter limits on lines per person. A roaming eSIM issued abroad isn't a Korean subscription, so KT or SK Telecom simply see a visiting roamer and no Korean identity record is created.
That's what makes Anon eSIM an anonymous eSIM in Korea: no passport, no face scan, no account and no ID at checkout. Your payment provider and the networks you connect to still see their own data, such as payment details and your device's identifiers.
On arrival: Incheon (ICN) SK Telecom / KT kiosks are efficient but demand passport. Pre-installed eSIM is on 5G on the AREX train to Seoul.
Typical speeds: 200-600 Mbps on 5G nationwide; among the fastest in the world. Prices from the live rates data: $2.80/GB, metered per MB against a prepaid USD balance.
Registration status
Passport required for local SIMs
Anon eSIM sidesteps this entirely - the eSIM is issued from an ID-free jurisdiction and you use it as a visitor's roaming SIM in South Korea. No local paperwork.
How does Anon eSIM compare with a Korean tourist SIM or a bundle eSIM?
A tourist SIM can include a Korean number but needs your passport and expires; Anon eSIM is data-only and per-GB, with no ID and no expiry.
| Option | Typical price | ID check | Data expiry | Korean number |
|---|---|---|---|---|
| Anon eSIM | $2.80/GB ($14 for 5 GB) | None | Never | No (data-only) |
| SK Telecom 5-day tourist SIM | ₩27,500* | Passport, plus 2026 identity checks | 5 days | Available with passport verification |
| KT 30-day prepaid | ₩35,000* | Passport, plus 2026 identity checks | 30 days | Yes |
| Bundle eSIM | About $9.90 for 5 GB* | Email account | Plan period | No |
*Local prices as reported in August 2026. Check current prices before you buy.
If you need a Korean number for delivery or banking apps, a passport-registered tourist SIM is the practical choice. For data, maps and messaging without handing over ID, the eSIM is simpler.

Which apps work best in Korea without a Korean number?
Naver Map or KakaoMap for directions, Papago for translation, KakaoTalk for messaging, and K.Ride for taxis.
Google Maps in Korea shows places and transit but has limited walking and driving directions, so most visitors switch to Naver Map or KakaoMap. KakaoTalk lets short-term visitors sign up with a foreign number.
Kakao T can be difficult with a foreign number or card; K.Ride is built for visitors. Some delivery, banking and government sites verify you by Korean number, which no data-only eSIM provides.

Does Google Maps work in Korea?
+
Partly. It shows places and public transit, but walking and driving directions are limited. Most visitors use Naver Map or KakaoMap instead, with Papago for translation.
Is 5G available to roamers?
+
Yes, on KT and SK Telecom across Seoul, Busan and most cities. Elsewhere you get fast LTE.
Does it work on Jeju Island?
+
Yes. Jeju is covered by KT and SK Telecom and billed at the Korea rate of $2.80/GB.
Will it work in Japan on the same trip?

Is hotspot included?
+
Yes. Your eSIM Korea balance covers hotspot at full speed with no separate cap, so you can tether a laptop in a Seoul café.
The bottom line
The easiest eSIM Korea setup is one you install at home: no passport, $2.80/GB on KT or SK Telecom 5G, and a balance that carries over to your next trip.
Flying on to Tokyo? The same balance works in Japan at $3.20/GB, and the rates page covers the rest of the world.
