Finland is Helsinki's design district and saunas in summer, and Lapland's northern lights, husky safaris and Santa's village in winter, with a night train or a short flight between them. Data matters for the HSL transit app, for aurora forecasts and for the booking apps that run most Lapland activities. Finnish SIMs are sold in R-kioski shops without much fuss, but an eSIM is live before the plane has parked at Vantaa. On 27 October 2026 we checked Finland eSIM prices across ONE eSIM, Airalo, Holafly, Saily and Nomad, lining up the cheapest plan at or above each size so the comparison is like for like.

Holafly sells only unlimited plans for Finland, so it has no price in the GB rows; its 7-day plan is in the week table below.
A week of unlimited data in Finland
| Provider | 7 days | What you get |
|---|---|---|
| ONE eSIM | $10.43 | 1 GB a day at full speed, then 512 Kbps until the next day (7 × $1.49) |
| Airalo | $27.00 | 3 GB a day at full speed, then 1 Mbps (fair use) |
| Holafly | $27.50 | No daily cap; fair use may slow very heavy use |
| Saily | $26.99 | 5 GB a day at full speed, then up to 1 Mbps |
| Nomad | $25.00 | 2 GB a day at full speed, then 1 Mbps |
For a week, ONE eSIM's 1 GB a day plan is the cheapest way to stay online all day at $10.43. The cheapest of the others is Nomad at $25.00, which gives more full-speed data a day; compare by how much you use a day, not by the word unlimited.
Which networks power Finland eSIMs
In Finland, ONE eSIM plans run on DNA, listed with 5G. Every plan names its network and generation before you pay, so you can pick the operator you want. Coverage follows each carrier's own build, so expect the strongest signal in the cities and along the main roads and rail lines, and check the plan's network if you are heading somewhere remote.
Which eSIM should you choose for Finland?
- Short trip, light use (up to 3 GB): ONE eSIM's 3 GB plan at $4.13 (15 days), the cheapest at that size.
- Two weeks or more (5 to 10 GB): ONE eSIM's 10 GB plan at $11.77 (30 days), the cheapest at that size.
- Heavy use (20 GB): Nomad at $20.00 (30 days) is the cheapest at 20 GB.
- Streaming or video calls every day: compare the unlimited plans above by how much full-speed data each gives a day.
Getting your Finland eSIM set up
- Confirm your phone supports eSIM and is carrier-unlocked before you buy.
- Install the eSIM over home or airport Wi-Fi before you fly; the QR code or install link needs a working connection to download.
- Land in Helsinki or Rovaniemi, switch on the eSIM line and enable data roaming, then check for a signal from DNA before you head for the taxi rank or the train.
Finland eSIM FAQ
- Does a Finland eSIM work in Lapland and on the aurora trips? In Rovaniemi, Levi, Saariselkä and along the main roads, yes; Finland's networks reach far north. Out on a frozen lake or deep in a national park the signal thins, which is the same on any SIM.
- Can I use the same eSIM for a day trip to Tallinn or Stockholm? Not a Finland-only plan. The ferry to Tallinn or Stockholm crosses into Estonia or Sweden; pick a Europe plan that lists all three and it covers the whole trip.
- Can I keep my home number active alongside a Finland eSIM? Yes. Most modern phones run two lines, so your home number stays available for calls and texts while the eSIM carries the data.
- Which networks does a Finland eSIM connect to? ONE eSIM's plans use DNA 5G; the other providers in this comparison may use different local partners.
- How much data do I need for a week in Finland? For maps, messaging and photos, 3 GB is enough for most people; add a bigger plan or the daily unlimited option if you stream or work on video calls.
How we check prices
We read each provider's public Finland page on 27 October 2026 and took its cheapest plan at or above each size, in US dollars before any coupon, with the validity in brackets; ONE eSIM prices are our live list prices on the same day. Prices move, so we re-check every month and keep the date on the page and in the short answer. If a number is out of date, write to support@oneesim.app and we will correct it.
