Helsinki Airport offers free, unlimited Wi-Fi with no sign-up. Not every Nordic airport works the same way, though: Stockholm Arlanda gives you up to three hours, and Oslo gives you four. Finland is also a country where most people rely on unlimited mobile data rather than free Wi-Fi. According to the Finnish Transport and Communications Agency (Traficom), 89% of household mobile subscriptions include unlimited data, and nearly half of all households have no fixed line at home and use only a mobile connection. This guide uses official information from airports, railways, government agencies and mobile operators to show where Wi-Fi works in Finland and the Nordics, and why you should carry your own connection.
If you want maps and transport apps working the moment you land, you can set up a Finland eSIM before you leave. Choose the data amount that fits your trip from Coral eSIM's Finland plans.
Internet in Finland: locals rely on mobile data, not Wi-Fi
Traficom's statistics, updated in September 2026, show how unusual mobile use in Finland is, even by European standards.
- 89% of household mobile subscriptions include unlimited data (92% for business subscriptions)
- Mobile data use was 78 GB per person per month (July to December 2025). For comparison, Traficom cites 38 GB per person per month in Sweden in 2024
- Nearly half of Finnish households connect to the internet only through a mobile network
- There were 9 million mobile subscriptions at the end of December 2025, or 1.6 per person
In other words, people in Finland usually just use their phone's own connection instead of looking for free Wi-Fi. Cafes and libraries have Wi-Fi, but cities are not built around free hotspots. As a traveler, plan to use your own connection on the move and treat Wi-Fi at airports and hotels as a backup.
Finland also made internet access of at least 1 Mbit/s downstream a universal service for everyone from July 2010. The minimum speed was raised to 5 Mbit/s in October 2021.
Finland and Nordic airport Wi-Fi: unlimited in Helsinki, 3 hours at Arlanda, 4 hours in Oslo
Helsinki Airport (Finland)
According to airport operator Finavia, the network is called "Helsinki Airport Free Wi-Fi". It is free and unlimited for all passengers, and you do not need a username or password. When you connect, a start page opens in your browser, and you begin from there. Finavia describes the speed as 100 Mb/s.
Stockholm Arlanda Airport (Sweden)
According to operator Swedavia, you get three hours of free Wi-Fi in total. You get one hour immediately, and two more hours after you confirm your email address. Coverage extends across all public areas, and Swedavia says the traffic is encrypted.
Oslo and other Norwegian airports
According to Avinor, which runs Norway's airports, you connect to the "AIRPORT" network, open your browser and select "Free". Free access lasts four hours, after which you need to log in again.
If you connect through several Nordic airports, the Wi-Fi rules differ at each one. To stay reachable after you leave the airport or during a connection, make sure your own line works as soon as you switch off airplane mode.
Finland train Wi-Fi: VR-wifi depends on base stations along the track
According to Finnish railway operator VR, the onboard network is called "VR-wifi". VR says it has upgraded the Wi-Fi transmitters on all long-distance trains, making them up to five times faster.
However, the onboard Wi-Fi connects to the internet through mobile base stations along the track. VR explains that there is no connection on sections without base stations, and that speed also depends on how full the train is. Its website includes a coverage map. For commuter trains in the Helsinki region, new trains with Wi-Fi are expected to start running towards the end of 2026.
On long trips north towards Lapland, you will often want to check maps or accommodation details. Where the train Wi-Fi drops, your own phone connection may still work, so it is worth having both.
Free Wi-Fi in Helsinki: Helsinki City Open WLAN
Helsinki's official tourism material lists "Helsinki City Open Wlan" as the free Wi-Fi network. Hotspots are concentrated in the city centre and at the harbours, and cafes, restaurants and libraries also offer Wi-Fi.
We could not confirm from official sources whether registration is required or whether the connection is encrypted. It is handy for finding a ferry terminal at the harbour or checking a map in the centre, but it is not a main connection.
Mobile internet speed and coverage in Finland and the Nordics
Ookla's Speedtest Global Index (August 2026) gives these median mobile download speeds:
- Finland: 117.30 Mbps (41st in the world); fixed broadband 168.53 Mbps (50th)
- Sweden: 133.32 Mbps (27th); fixed broadband 195.74 Mbps (39th)
- Norway: 145.09 Mbps (22nd); fixed broadband 157.27 Mbps (52nd)
- Denmark: 161.03 Mbps (17th); fixed broadband 278.16 Mbps (14th)
In Finland, the gap between fixed and mobile speeds is relatively small. According to Traficom, at the end of June 2026, 100 Mbit/s 4G covered 96% of households and 5G covered 93%. By land area, however, 4G covered only 29% and 5G 20%. Coverage is good where people live, but expect weak signal in parts of the forest and lake countryside and in national parks.
3G is gone in the Nordics: check older phones
Finland no longer has a 3G network. Elisa shut down 3G in November 2023, DNA between October 2023 and January 2024, and Telia Finland switched off its last base stations in Helsinki at the end of October 2024. In Sweden, the largest operators shut down 3G in December 2025, and according to the Swedish Post and Telecom Authority (PTS), since 2 February 2026 operators must block phones that cannot call the emergency number 112. Telenor Norway switched off 3G in January 2021, and in Denmark, 3 completed its 3G shutdown in December 2025.
In the Nordics, assume that you need a 4G or 5G phone for mobile data. If you are bringing an older iPhone, check eSIM and 4G support in using an eSIM on an older iPhone, and check your model in how to check eSIM support.
Using free Wi-Fi in Finland safely: advice from the National Cyber Security Centre
The National Cyber Security Centre Finland (NCSC-FI) gives this advice for travelers:
- Use your own mobile data connection first
- Avoid open, unprotected Wi-Fi and avoid logging in to sensitive services
- Use a VPN if needed
It is worth remembering that a Finnish public authority tells travelers to use their own mobile connection first. Switch to your own line before online banking, entering card details or logging in to accounts. For more, see free Wi-Fi security tips.

In Finland, do what locals do: make your own mobile connection the main one, not Wi-Fi
Helsinki Airport's unlimited Wi-Fi is convenient, but some Nordic airports have time limits, train Wi-Fi depends on base stations, and city Wi-Fi is concentrated in the centre and at the harbours. Locals live on unlimited mobile data, and the National Cyber Security Centre tells travelers to use their own connection first. Set up a travel eSIM before you leave so you have your own line, and use free Wi-Fi at airports and hotels as a backup. That is the simplest way to stay connected in Finland and the Nordics.
