Most visitors to Finland start in Helsinki and then either head north to Lapland, for the northern lights, husky safaris and Santa Claus Village in Rovaniemi, or cross the Baltic by ferry to Tallinn or Stockholm. For EU SIM cards, Finland is covered by Roam Like at Home; travellers with a SIM from outside the EU usually pay roaming by the day.
Key facts for Finland
- EU roaming: covered by Roam Like at Home
- Local networks: DNA, Telia, Elisa (depending on the plan)
- Emergency numbers: 112
- Embassies: in Helsinki
Helsinki
Trains link Helsinki Airport with the city centre in about 30 minutes, and coverage is strong across the city. On trams, buses, the metro and commuter trains, you can buy a single ticket by tapping a Visa or Mastercard contactless card on the reader, and the HSL app sells day tickets for longer stays.
The ferries to Tallinn and Stockholm
Ferries to Tallinn take about two hours, and phones switch to Estonian networks on the way; with an EU SIM, that is still Roam Like at Home. Out at sea, and on the overnight ships to Stockholm through the Åland Islands, phones can connect to the ship's own network, which is billed at satellite rates and is not covered by EU roaming. Turn off data roaming at sea, or choose a land network manually when one is in range. A Finland-only travel plan does not include Estonia or Sweden, while a Scandinavia or Europe plan covers all three.
Lapland
Coverage is good in Rovaniemi, Levi, Saariselkä and along the main roads, but it thins out in the wilderness and on long snowmobile or husky trips. In winter, temperatures can fall below −30 °C, which drains phone batteries very quickly, so keep your phone inside your clothing and carry a power bank. Reindeer often stand on the roads; if you hit one, call 112, even if the collision seemed minor.
Lakes, cottages and the midnight sun
In summer, the nights stay light in the south, and in Lapland the sun does not set for weeks around midsummer. Rental cottages in the Lakeland around Savonlinna and Lake Saimaa are often far from the nearest town, and some rely on mobile data for their Wi-Fi, so ask your host about coverage before you book.
Paying
Finland is one of the most card-friendly countries in Europe: almost everywhere takes cards and phone payments, from market stalls to taxis.
Getting connected
EU SIM: Finland counts as home for roaming, so your usual data applies on land. A travel eSIM is worth it only if your tariff includes little data in the EU.
SIM from outside the EU: set up a travel eSIM before you fly. It starts on its first connection in Finland, and your usual number stays reachable for texts and bank codes.
Finnish prepaid SIMs are sold in supermarkets and R-kioski convenience stores.
Consular protection: who to call in Finland
- 112 reaches the police, ambulances, the fire service and sea and mountain rescue.
- 116 117 gives medical advice when it is not an emergency.
- Embassies are in Helsinki. The Telcomia app shows yours, with address and phone.
- The app has emergency phrases in Finnish, ready to show on screen.
