Does data work in remote places such as Lapland or the best Northern Lights spots?

Finland has fairly good telecoms infrastructure even in remote areas. At the main Northern Lights destinations, such as Rovaniemi and Saariselkä, a stable connection is mostly available. However, the signal may weaken in the most remote areas north of Inari or on trekking routes deep in the national parks, so we recommend saving offline maps beforehand.

Which season suits a trip to Finland? When can I see the Northern Lights?

To see the Northern Lights, go between late August and March; your chances are highest from December to February in particular. If you head to Lapland, you get far more chances to see them, and you can also enjoy winter activities such as snowfield tours and reindeer sleigh rides. If you want to experience the summer white nights, visit in June–July. The sky is still bright even at 11 p.m.

Can I also make calls or send texts with my Korean phone number while using it in Finland?

Yeohaengyusim eSIMs are data-only plans as standard. To receive calls or texts on your Korean number, keep your existing Korean SIM in your device and use the dual SIM feature. If your smartphone supports dual SIM, you can use your Korean SIM and your Finland eSIM at the same time.

Can I use it the moment I reach the airport in Finland?

Yes. If you install your Yeohaengyusim eSIM before departure Korea, it links up automatically with the Elisa network as soon as you land at Helsinki-Vantaa Airport. You don't need to look for airport Wi-Fi or wait at a SIM exchange booth; you can open Kakao Map, Google Translate and transport apps right away.

Will I need a power adapter in Finland?

Finland uses Type C/Type F outlets, the European standard. They are a different shape from Korean outlets, so you need a European-style adapter. The voltage is 230V, so most Korean devices (220V) are compatible, but be sure to check your device specifications before departure.

Does eSIM work in Finland?

Finland supports eSIM, and plans start from ₩1,944. 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 Finland?

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 Finland eSIM use?

In Finland it connects automatically to local carrier networks such as Elisa · Telia Finland · DNA (4G/LTE, 5G where supported). Population coverage is about 99%. It picks the network with the strongest signal automatically, so there is nothing to set up.

Can I add to or extend my Finland 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 Finland?

Yes. In Finland 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 Finland. Just remember "set up before you leave, switch on when you arrive" and you can use the internet as soon as you land.

How many GB of data do I need for a trip to Finland?

For mostly maps and messaging, we recommend about 1 GB a day; to use plenty of social media and photo uploads, about 2 GB a day. If you stream a lot of video or tether a lot, an unlimited plan is better. You can always buy more if you run short, so it is fine to choose a little extra at first.

Finland, the country where green Northern Lights dance over white snowfields. From the stylish urban feel of Helsinki to Rovaniemi, the hometown of Santa Claus, and the endless snowfields of Lapland, Finland offers fairy-tale scenery whenever you come. It is a romantic place where you can soak up the mystery of the white nights in summer and chase the Northern Lights all the way to the Arctic Circle in winter. But to avoid getting lost in this vast wilderness, a stable internet connection is essential. From searching for the best Northern Lights viewing spots to navigating to remote forest lodges and using local transport apps, one Yeohaengyusim eSIM lets you explore every corner of Finland with peace of mind. Install it in Korea in advance and get connected right after landing at Helsinki-Vantaa Airport.

Why you need a travel eSIM for Finland

Finland boasts world-class digital infrastructure. Local carriers such as Elisa and Telia Finland provide dense 4G/LTE and 5G networks, with wide coverage reaching 99%, not only in Helsinki, the capital, but all the way to Lapland near the Arctic Circle. The problem is that buying or swapping a local SIM in this vast country is never easy. Central Helsinki may be a different story, but finding somewhere that sells SIMs near Lake Inari or near cabin accommodation around Oulu is hard. With a Yeohaengyusim eSIM, you install it easily before departure Korea, and it connects automatically to a local network the moment you set foot in Finland. You don't need to swap SIM cards and no worry about outrageous international roaming charges. Everything from checking your Northern Lights tour booking and the weather in real time to Google Maps navigation works without interruption. Even deep in Finland's wilderness, Yeohaengyusim will keep you reliably connected.
