Traveling to Greenland means venturing into the world's largest island: icebergs, northern lights, and towns accessible by boat or plane, never by road. In such a remote place, knowing how you'll have internet is key, and an eSIM for Greenland saves you from your Spanish plan's expensive roaming fees and the uncertainty of where to buy a SIM card. Here you'll find real coverage, the local operator, how many GB to bring, and why the connection works differently than in any other destination.
Do you need an eSIM in Greenland?
Yes, if you want reliable data without paying a fortune. Greenland is not in the EU's surcharge-free roaming zone, so your Spanish plan will incur expensive international roaming charges. A data eSIM for Greenland installs in a minute and connects you to the local network, although it's helpful to understand how the connection works in such an isolated territory first.
Typical plans here include west coast cruises, aurora borealis viewing in winter, summer hiking under the midnight sun, or routes between Nuuk, Ilulissat, and the ice fjords. In all of these, you'll want to share those incredible photos, check the weather (which changes quickly), and coordinate excursions. Relying on Wi-Fi is risky: outside of hotels and cafes in cities, there's barely any, and distances between towns are enormous. An eSIM gives you data wherever there's coverage, and your Spanish SIM continues to receive calls with your number.
How the connection works on the island
To the point: in Greenland, there is mobile coverage, but only around inhabited cities and towns. The interior, covered by the ice cap, and routes between settlements by sea lack signal. The network is concentrated on the coast, where people live, and operates via satellite and radio links to the outside world.
This changes your way of traveling compared to a normal European destination. Don't expect 5G in the middle of a fjord or on a boat between towns: there are no antennas there. The realistic expectation is to have good data in Nuuk, Ilulissat, Sisimiut, Qaqortoq, and the main localities, and offline navigation for the rest. Download maps of the area and information for your excursions when you have urban coverage. An eSIM will give you internet whenever a local network is available, which is in the areas where you'll spend most of your time between transfers anyway.
Reality on the ground: there are no roads connecting cities in Greenland. You travel by plane, helicopter, or boat, and there is no coverage on these journeys. Download maps and guides before leaving each town.
Local operator and coverage by zone
The island's telecommunications operator is Tusass (formerly TELE Greenland / TELE-POST), the only company providing mobile service and internet throughout the territory. A travel eSIM relies on the Tusass network, so you don't need to buy their physical card in Nuuk or register locally.
- Nuuk (capital): the best coverage on the island, with stable 4G for maps, social media, and video calls.
- Ilulissat: good signal in the ice fjord city, the main tourist base in the west.
- Sisimiut, Qaqortoq, Nanortalik: coverage in the urban core.
- Icy interior and sea crossings: no coverage; essential to plan offline.
Speed is adequate in cities, but don't expect fiber optics: it's an Arctic territory with a scattered population. To avoid surprises, refer to our general guide on how to avoid roaming and have your eSIM ready before landing.
Greenland is Danish, but not like Denmark
Greenland is an autonomous territory of the Kingdom of Denmark, but it is not part of the European Union, unlike mainland Denmark. This is a nuance that directly affects your mobile: your Spanish plan doesn't give you "roam like home" here, although it would in Copenhagen.
That's why many travelers stop over in Denmark or Iceland on their way to Greenland and get confused, thinking their European plan covers everything. That's not the case: in mainland Denmark, you're in the EU, but when you fly to the island, you leave the surcharge-free roaming zone. If your route passes through Iceland (a common stopover), an Iceland eSIM will also be useful, as Iceland is also not in the EU. In short: each Arctic leg needs its own data solution, and it's good to be clear about this before taking off.
How many GB you really need
Since a good part of the trip takes place without coverage (on a boat, on the ice, on air routes), the actual consumption is lower than in an urban destination. For one or two weeks, with usage in cities and photo uploads, 3-5 GB is usually enough. Here's a guide by trip type.
| Trip Type | Typical Use | Recommended Data |
|---|---|---|
| Expedition Cruise | Data only at port calls | 1-2 GB |
| Week in Nuuk / Ilulissat | Maps, social media, photo uploads | 3-5 GB |
| Two weeks across several cities | Photos, light video, planning | 5-8 GB |
| Remote work from the capital | Video calls, email, cloud | 10 GB or more |
Since you'll spend long stretches without a network, take advantage of urban coverage to download and schedule. Our guide on how much data you need for travel helps you fine-tune the calculation based on the apps you use.
How to activate your eSIM before departing
eSIM installation requires a connection, so do it with Wi-Fi at home before you fly, especially when going to a destination where the network is scarce. The entire process takes less than a minute, and you'll arrive with data ready.
- Check that your mobile is eSIM compatible.
- Purchase your eSIM for Greenland and receive the QR by email.
- Install it with Wi-Fi before flying (Settings > Mobile Data > Add eSIM).
- Upon landing in Nuuk or Kangerlussuaq, activate the eSIM data.
If it's your first time, follow the step-by-step instructions on how to activate an eSIM. Install the eSIM before leaving Spain: in the Arctic, you won't want to rely on finding Wi-Fi to get it started.
Frequently asked questions
Is there mobile coverage throughout Greenland?
No. Coverage is concentrated in coastal cities and towns, where the population lives. The icy interior and sea crossings between settlements have no signal. An eSIM works in inhabited areas; for the rest, plan with offline maps downloaded in advance.
Does my European plan work if Greenland is Danish?
No. Although Greenland is a territory of the Kingdom of Denmark, it is not part of the EU, so you don't have "roam like home." Your Spanish plan will incur expensive international roaming charges. That's why a local eSIM is advisable, different from what you would use in Copenhagen.
What is the phone operator in Greenland?
Tusass (formerly TELE Greenland) is the island's sole telecommunications company and provides all mobile coverage. A travel eSIM automatically relies on its network, so you don't need to buy their physical card or register upon arrival in Nuuk.
Will I have internet during a fjord cruise?
Only at port calls, when the ship reaches a town with coverage. Between ports, while sailing at sea or near ice, there is no mobile signal. Many cruises offer paid satellite Wi-Fi on board, but it is usually slow and expensive.
How many GB should I buy for two weeks?
Since you'll spend a lot of time without coverage, consumption is lower than usual. With 5-8 GB, you have enough for two weeks with urban usage and photo uploads. If you work remotely or make frequent video calls, increase to 10 GB or more.
Conclusion
Greenland is one of the most remote destinations on the planet, and its connection works differently: data in coastal cities, nothing on the ice or at sea. With a local eSIM, you'll arrive with internet ready, avoid international roaming, and take advantage of urban coverage to plan your excursions. Install your eSIM for Greenland before flying to the Arctic and enjoy the icebergs without worrying about the bill.
