Aurora trips go north: to Tromsø in Norway, Abisko and Kiruna in Swedish Lapland, Rovaniemi and Finnish Lapland, or out of Reykjavík into the Icelandic countryside. Chasing the lights often means leaving town at night, into the dark and the cold. All four countries are inside Roam Like at Home, so for EU SIMs the real challenges are signal, cold and darkness.
This guide to an eSIM for a Northern Lights trip covers who needs one, a single plan for Tromsø, Lapland and Iceland, signal away from towns, the cold, and the numbers to save.
Key facts for a Northern Lights trip
- EU roaming: Sweden and Finland are in the EU, Norway and Iceland in the EEA; Roam Like at Home applies in all four
- One plan for the route: the Scandinavia & Baltic plan covers Norway, Sweden, Finland and Iceland
- Emergency numbers: 112 in all four; in Norway, 113 for an ambulance
- Embassies: in Oslo, Stockholm, Helsinki and Reykjavík
Who needs an eSIM for a Northern Lights trip
With an EU SIM, all four countries count as home for roaming. A travel eSIM only helps if your tariff includes little data abroad.
With a SIM from the UK, the US or elsewhere outside the Roam Like at Home area, roaming is usually charged by the day. One Scandinavia & Baltic plan on an eSIM covers Tromsø, Swedish and Finnish Lapland and Iceland, while your home SIM keeps your own number.
In the far north, Norway, Sweden and Finland share borders, and near them a phone can connect to the neighbouring country's network. On a country plan, or near any other border, choose the local network manually in your mobile settings.
Signal away from town
Coverage is good in towns such as Tromsø, Kiruna and Rovaniemi and along most main roads. Away from them it can be sparse: in the mountains, on long trails such as the Kungsleden, in the Finnish wilderness and in Iceland's interior.
Aurora forecast and weather apps need data, so check them while you still have signal, and download offline maps before you drive out. In northern Norway, winter storms can close roads at short notice, so check the road status first. In Iceland, SafeTravel posts alerts about storms and closed roads, and the 112 Iceland app can send your location to the emergency services.
Cold, darkness and battery life
Cold drains phone batteries faster, and on an aurora night the phone is your map, forecast and camera at once, so keep it warm and carry a charged power bank. Coverage also thins out on long snowmobile or husky trips, so on those, as on long walks, tell someone your route.
Which plan fits your trip
With an EU SIM, you may need nothing extra. From outside the Roam Like at Home area, Telcomia's Scandinavia & Baltic plan covers all four countries on one eSIM, plus Denmark and the Baltic states. The Europe plan covers Norway, Sweden and Finland but not Iceland.
A country plan, such as Iceland, suits a trip that stays in one country. Open the plan details before you buy: they show the duration, the data, whether you can share the connection with other devices, and the Activation line, which tells you what starts the plan's validity.
Before you leave
- Read the Activation line in the plan details, then install the eSIM at home on Wi-Fi.
- Set the eSIM as your mobile data line, with data roaming on for the eSIM and off for your home line.
- Download offline maps of the areas where you will look for the lights, and pack a charged power bank.
- In Iceland, install the 112 Iceland app before you head out.
- Keep the eSIM installed until the trip is over: some eSIMs can be installed only once.
Consular protection: who to call in the far north
- 112 reaches the emergency services in Sweden, Finland and Iceland. In Norway, 112 is the police, 113 an ambulance and 110 the fire service; a call to 112 is transferred if needed.
- Embassies are in Oslo, Stockholm, Helsinki and Reykjavík. The Telcomia app shows which mission is responsible for you, with address and phone.
- If you are an EU citizen and your country has no embassy or consulate in Norway or Iceland, the embassy of any other EU country must help you on the same terms as its own nationals (Article 23 of the Treaty on the Functioning of the EU).
- Emergency phrases in Norwegian, Swedish, Finnish and Icelandic are ready to show on screen in the app.
Questions travellers ask about a Northern Lights trip
Is there signal when chasing the Northern Lights?
In towns and along most main roads, yes. Away from them, in the mountains and in Iceland's interior, coverage can be sparse, so check the aurora forecast and download offline maps before you leave town.
Does EU roaming work in Tromsø and Iceland?
Yes, for SIMs from EU countries. Norway and Iceland are in the European Economic Area, so Roam Like at Home applies there as in Sweden and Finland.
How do I keep my phone working in the cold?
Cold drains batteries faster, so keep it in an inside pocket, close to your body, between photos. Charge it fully before every night out and carry a power bank.
Which emergency numbers should I save?
112 works in all four countries. In Norway, also save 113 for an ambulance, and in Iceland install the 112 Iceland app.
The short version
With an EU SIM, all four countries count as home; from elsewhere, one Scandinavia & Baltic plan covers Tromsø, Lapland and Iceland. Check the forecast and download maps before leaving town, keep your phone warm and charged, and save 112 and Norway's 113.

When should I activate my Iceland eSIM?
Each plan shows before you pay when it starts counting. Plans that start on connection start counting the first time they connect to a network in one of the countries they cover: install the eSIM before you leave, keep the line off until you arrive in Iceland, and you'll have data as soon as you land. Some also work in other countries (each plan lists which): if the line connects earlier, at home or on a layover, it starts counting there. Plans that start when you buy them are best bought on the day you'll start using them.
