Does the eSIM cover the trip from Incheon into central Seoul?

Yes. It's one national plan, so it stays connected the whole way - on the AREX express, the all-stop metro, or an airport bus. You'll have live directions from Incheon straight through to your Seoul accommodation.

Is coverage good in Songdo and around Incheon's islands?

Songdo, being a new smart city, has excellent 5G, and central Incheon and Chinatown are well covered. On outlying islands like Ganghwa, signal is still reliable but can thin near remote coastal temples and dolmen sites.

Good to know in Incheon

From the airport, the AREX all-stop train and Incheon Metro Line 1 both need live times - your eSIM works the moment you land, so you can plan the route to Seoul before leaving arrivals.

Two simple ways to buy

Incheon eSIM plans: unlimited, or by the GB.

Every Incheon eSIM from My Holiday SIM is one of two straightforward types. Pick whichever fits how you travel in Incheon — 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.
