Network & Coverage

Stay connected across every corner of Incheon

Your eSIM connects to SKTelecom and LG Uplus — both with 5G — across Incheon and on through South Korea. The phone takes whichever network is strongest where you stand.

Where you will use it
the airport terminalsSongdothe old port and Chinatownthe AREX line into Seoul

Incheon runs free transit tours for passengers with long layovers, and booking or finding them is done entirely on a phone in a terminal where roaming charges are exactly what people are trying to avoid.

Does the Incheon eSIM work outside the city?+
Yes — it is a South Korea-wide plan. This page exists because people search for the city, not the country.
Can I share it as a hotspot in Incheon?+
Yes. Tethering is allowed, which is what makes one unlimited line practical for a couple or a family moving around together.

How it works

Connected in
3 simple steps

1
Before you fly
Scan the QR code over Wi-Fi. About a minute.
2
On landing at ICN
Turn off flight mode — the line registers by itself.
3
Turn on data roaming
The step most travellers miss. It is not roaming in the billing sense; it is how the phone lets the eSIM use a foreign network.
✈️
Ready before you land
The airport itself — most people searching for Incheon mean the terminal, not the city — and your eSIM is already working when you get there.

Frequently asked questions

Everything you need to know about your Incheon eSIM

Is the data truly unlimited?+
There is a fair use policy, as with every unlimited plan on the market. We publish the details on our fair use page rather than bury them, so you can check before you buy.
When does my Incheon eSIM activate?+
On its first connection to a local network — in practice when you switch off flight mode at ICN. Not when you pay.
Can I buy it weeks before the trip?+
Yes. It stays dormant until it first connects, so buying it together with the flight is fine.
Should I buy a SIM card at the airport instead?+
You can, but it means queueing after a flight and paying whatever the counter asks. An eSIM bought beforehand is already working before you reach passport control.
Which devices are compatible?+
Any eSIM-capable handset — iPhone XS and newer, recent Samsung Galaxy, Pixel 3 and newer. Dial *#06# — if an EID number appears, you are good to go.
Can I extend it if I stay longer?+
We do not extend a plan that is already running. For more days, buy another eSIM for the same destination — it arrives by email and installs alongside the one you already have.
Only staying a few days?
A short trip is usually cheaper on a fixed data plan — same networks, one price for the trip.
