The one country where the travel eSIM is usually the worse deal: unlimited prepaid data costs about a euro a day, with no registration and no paperwork.

  • Finland has some of the cheapest mobile data in the European Union, which inverts the usual advice: buy a local SIM here, not a travel eSIM.
  • DNA's Rajaton Prepaid is the benchmark - unlimited calls, texts and data in Finland and across the EU and EEA at roughly EUR 0.99 to EUR 1.29 per day, charged only on days you use it.
  • There is no registration. No passport, no form, no waiting, which is why an R-kioski or a supermarket checkout can sell you one in a minute.
  • Coverage thins in Lapland, the lake district and the archipelago. A cabin an hour from Rovaniemi with one bar of 4G is normal rather than a fault.
  • Winter matters more than distance. A phone at minus 20 loses charge in minutes and can shut down outright, so carry it inside your coat and take a power bank.

Buy local, not a travel eSIM

Finland has some of the cheapest mobile data in the European Union, which inverts the advice that works almost everywhere else. A travel eSIM is sold by the gigabyte; a Finnish prepaid SIM sells you unlimited data for about the price of a coffee per week. If you are here for more than a few days, the local card wins on value even though the eSIM wins on convenience.

  • DNA's Rajaton Prepaid is the benchmark: unlimited calls, texts and data in Finland and across the EU and EEA, at roughly EUR 0.99 to EUR 1.29 per day, charged only on days you use it.
  • Telia sells unlimited 4G for about EUR 9.90 for 7 days or EUR 19.99 for 31 days.
  • Elisa's prepaid packages run to about EUR 29.99 a month and are the dearest of the three, with the best rural reach in parts of the north.
  • There is no registration. No passport, no form, no waiting. You buy the SIM and it works.

Where to buy one

  • R-kioski is the answer for most arrivals. The green kiosks are everywhere, including at the airport and Helsinki Central Station, and they sell all three networks.
  • Supermarkets - Prisma, K-Citymarket, S-market - sell them at the checkout.
  • Operator shops in any shopping centre will set the phone up for you if the menus defeat you.
  • The airport has one before you reach the train, so you do not have to arrive online.

Coverage and the bit that catches people out

  • Coverage along the inhabited south and the main roads is excellent, and 5G reaches every city.
  • It thins out in Lapland, in the lake district and on the archipelago. A cabin an hour from Rovaniemi may have one bar of 4G and nothing else, and that is normal rather than a fault.
  • Winter matters more than distance. A phone at minus 20 loses charge in minutes and can shut down outright, so carry it inside your coat and take a power bank on any day out.
  • Download offline maps before driving north. The distances between petrol stations are large and the signal is not continuous.
  • EU roaming applies, so a SIM from any EU country works here at home rates and a Finnish SIM works across the EU - which makes the local SIM good value even if Finland is one stop of several.
