Will the eSIM work on the Seoul metro as well?

Yes, without any problem. The Seoul metro is entirely served by 4G and 5G networks thanks to the extensive infrastructure of SK Telecom and KT. You can browse, use Kakao Maps and stream music even in the deepest stations, never losing the signal.

Is the eSIM usable on KTX high-speed trains?

Absolutely. The KTX trains linking Seoul to Busan, Daegu and Gwangju run through areas with continuous coverage. You may notice brief signal drops in some mountain tunnels, but the connection is restored within moments. Ideal for working or watching content during the journey.

Is an adapter required to charge my phone in South Korea?

No, there is no need for an adapter. South Korea has Type C and F sockets — the same ones common in Italy and the rest of Europe — at 220V. Your European chargers will plug straight into Korean sockets without any additional accessory.

How much do I save compared with roaming on an Italian SIM in South Korea?

The saving is considerable. Roaming with an Italian SIM in South Korea — a country outside the EU's “Roam Like at Home” area — can cost between €10 and €25 a day, often at reduced speeds. A Datiovunque eSIM dedicated to South Korea offers high-speed data for a fraction of the cost, with the convenience of digital activation even before boarding the plane.

How much does an eSIM for South Korea cost?

eSIM plans for South Korea start from €2.79. You pay once for the amount of data you choose — no subscription, no monthly fees and no hidden roaming charges. Plans with more data or longer validity cost more.

Which operator or network does the eSIM use in South Korea?

The eSIM in South Korea connects automatically to local networks such as SK Telecom, KT, LG U+ — on 4G/LTE and, where available, 5G. Coverage reaches about 99% in inhabited areas. Your phone picks the best available network by itself.

Can I keep my Italian number with the eSIM in South Korea?

Yes. Your Italian SIM and number stay active — the travel eSIM works alongside it as a data-only line. You stay reachable on WhatsApp, iMessage or Wi-Fi while you use the local network to browse. Traditional calls and SMS still go through your Italian number.

Should I activate the eSIM before or after I leave?

Install the eSIM at home, on Wi-Fi, before you leave. The data plan then activates automatically when you connect in South Korea. That way you are online as soon as you arrive, without looking for airport Wi-Fi or buying a local SIM.

Can I top up or renew the plan for South Korea?

Yes. When the data runs out or the validity expires, just buy a new plan — the eSIM profile already installed is kept and does not need to be installed again. You stay connected without interruption.

Can I share the connection (hotspot) in South Korea?

Yes. You can share the connection in South Korea through a personal hotspot with a computer, tablet or other devices. Shared data is deducted from your plan, so allow a few extra gigabytes if you expect to use the hotspot often.

How many GB do I need for South Korea?

For a normal trip, 1–3 GB a week is enough for maps, messages and occasional browsing. With social media and photo sharing allow about 5 GB; for streaming, video calls or a hotspot count on 10 GB or more. If the volume is not enough, you can buy an additional plan at any time.

Seoul pulses at a rhythm that leaves you breathless: the neon alleys of Hongdae, the Joseon palaces of Gyeongbokgung, the night markets of Myeongdong and K-culture exploding from every corner. South Korea is also the nation with the quickest mobile network on earth, and yet without a connection of your own you soon find yourself short of maps, Hangul translations and last-minute bookings at the most sought-after restaurants. With a Datiovunque eSIM activated before leaving Rome, when you land at Incheon 5G is waiting in your pocket, with no queues and no physical SIM, just an immediate connection in one of the most digitally advanced nations on the planet.

Why an eSIM is indispensable in South Korea

South Korea boasts among the most developed mobile infrastructures in the world: operators such as SK Telecom, KT and LG U+ blanket 99% of the territory with 4G/LTE and 5G networks, even in the underground stations of the Seoul metro and along the KTX high-speed lines to Busan. And yet, for a foreign visitor, getting a local SIM at Incheon airport means facing queues on arrival, contracts in Korean and often restrictions tied to the passport. With an eSIM these steps simply do not exist. Google Maps will guide you through the maze of the Seoul metro, translate menus in Hangul, call your Airbnb hosts through an app and stream your favourite content without slowdowns. The gap from Rome is +8 hours in summer (+8 in winter as well): having the internet working from the first minute means you can let home know straight away that you have landed, without depending on the congested public Wi-Fi of the terminals.
