Are the Åland Islands part of Finland or Sweden? Which country's eSIM should I use?

The Åland Islands are an autonomous region of Finland and belong to an EU member state. However, they have an independent network environment that runs its own telecoms networks (Ålands Telekommunikation, Telia). If you choose an Åland Islands eSIM or a Europe-wide eSIM from Yeohaengyusim, you can connect smoothly to the local network.

Does data work well on the remote islands and in the natural areas of the Åland Islands?

Together, the Ålands Telekommunikation and Telia networks provide 4G LTE coverage across about 95% of the islands. You can use it reliably in central Mariehamn and on the main inhabited islands. However, coverage can be patchy at the edges of extremely remote uninhabited islands, so we recommend downloading important maps and information in advance.

Will my data drop when I take a ferry from the Åland Islands to mainland Finland or Sweden?

During the ferry crossing, the signal may weaken or drop for a while at sea. Large ferries sometimes offer onboard Wi-Fi. When you arrive at a port in mainland Finland or Sweden, the eSIM switches automatically to that country's network, so if you choose a Europe-wide eSIM you can keep using it without interruption even when you cross borders.

Will I need a power adapter when travelling in the Åland Islands?

The Åland Islands use European-standard Type C/F outlets. These differ from Korean plugs (Type A or round Type C), so it pays to bring an adapter. On a cycling trip in particular, you often need to charge your devices at your accommodation, so get one ready in advance.

Which season suits a trip to the Åland Islands?

The best time is June–August, the short Nordic summer. The days are very long, so you can experience bright white nights even after 10 p.m., and the sea warms up, which makes it good for swimming or kayaking. Late May and early September are also cool and pleasant, perfect for a cycling trip.

Does eSIM work in Åland Islands?

Åland Islands supports eSIM, and plans start from ₩5,108. Install it with the QR code you receive after buying, then just turn on data roaming after you arrive and you are connected straight away. There is no need to swap your SIM.

Travel eSIM or carrier roaming: which is cheaper for a trip to Åland Islands?

For a short trip or light data use, a travel eSIM is usually cheaper. Unlimited roaming from Korean carriers costs about ₩11,000–₩15,000 a day, but with an eSIM you can buy just the days of data you need in advance. For a short trip for one or two people, an eSIM has a big advantage; for a family or very heavy data use, compare carrier unlimited roaming too.

Which carrier network does a Åland Islands eSIM use?

In Åland Islands it connects automatically to local carrier networks such as Ålands Telekommunikation · Telia · Elisa (4G/LTE, 5G where supported). Population coverage is about 95%. It picks the network with the strongest signal automatically, so there is nothing to set up.

Can I keep using my Korean number while travelling in Åland Islands?

Yes. The eSIM works as a data-only second line, so your Korean SIM and number stay as they are. Use the Yeohaengyusim eSIM for data only, and keep receiving calls, texts and KakaoTalk on your Korean number.

Can I add to or extend my Åland Islands eSIM plan?

Yes. When you use up your data or the plan period ends, you can buy a new plan at any time. Keep using the eSIM profile you already installed; there is no need to install it again, so you carry on without interruption.

Can I use tethering (hotspot) in Åland Islands?

Yes. In Åland Islands you can share your eSIM data with other devices such as a laptop or tablet by tethering (hotspot). Shared data also comes out of your plan allowance, so if you tether a lot we recommend choosing a little more data.

Do I set up the eSIM before I leave or after I arrive?

We recommend installing it (registering the QR code) before you leave, while you have Wi-Fi. Data starts when you turn on data roaming after you arrive in Åland Islands. Just remember "set up before you leave, switch on when you arrive" and you can use the internet as soon as you land.

Set in the middle of the Baltic Sea, the Åland Islands are made up of some 6,700 islands scattered between mainland Finland and Sweden. Although it is an autonomous region of Finland, it has a unique, blended culture with Swedish as its official language, where medieval castles, picture-perfect harbour villages and vast nature come together. In summer especially, the clear sea and red wooden buildings make a scene straight out of a fairy tale. As you cycle around the islands and take small ferries to explore uninhabited islands, you discover the real charm of the Nordics. Even on remote islands like these, one Yeohaengyusim eSIM lets you use Google Maps and local information without a hitch, so you can enjoy Åland in a more relaxed and freer way.

Why an eSIM really helps in the Åland Islands

The Åland Islands are an archipelago of thousands of islands. Once you leave central Mariehamn and move between the small islands, it is not easy to find a shop that sells local SIMs. If you install a Yeohaengyusim eSIM in Korea before departure, it connects to 4G LTE on arrival, so you don't need to hunt for a SIM. The Åland Islands are under Finnish jurisdiction but sit within the EU's single telecoms area, and the Ålands Telekommunikation and Telia networks provide 95% coverage across the islands. Checking your route on Google Maps as you cycle to remote islands, looking up ferry timetables in real time, booking accommodation on the spot: one eSIM handles it all. You keep your existing Korean number without swapping SIM cards, so you stay in touch with family and friends. Because of the nature of travel in the Nordics, some areas have underdeveloped local Wi-Fi infrastructure, so securing reliable mobile data is especially important.
