Best eSIM for Denmark 2026: 14 Providers Compared

Denmark's four mobile networks reach the Copenhagen Metro, the Great Belt crossing and most of Jutland, so an eSIM installed at home has you online from Kastrup onward; only the Faroe Islands and Greenland need a separate plan. Whether you are cycling across Copenhagen's harbor bridges, hopping the metro to Kastrup, coordinating a design-studio tour in Aarhus, or chasing the light at Skagen's northern tip, a steady mobile connection is now as essential as your passport. A Danish eSIM removes the friction of a physical SIM: no queues at a kiosk, no juggling a plastic card, no roaming bills at the end of the month. You install the profile before you fly, land at Copenhagen Airport already online, and pick up right where your itinerary starts.

EU roaming covers Denmark, but not the Faroes or Greenland

Visitors with a phone plan from another EU country are already covered in Denmark: the European Commission's Your Europe roaming page confirms that roam like at home applies across the EU and in Iceland, Liechtenstein, Norway, Moldova and Ukraine, and that other countries are not covered by the regime. A Denmark travel eSIM mainly helps EU residents whose home allowance is small, and everyone else, including visitors from the US, the UK, Canada and Australia.

The Faroe Islands and Greenland belong to the Kingdom of Denmark but sit outside the EU, so neither an EU plan nor a Denmark eSIM can be counted on there. They run their own operators, Faroese Telecom and Hey in the Faroes and Tusass in Greenland, and a trip to either needs a plan that lists them by name.

Checking coverage on Denmark's official tjekditnet map

Denmark publishes its own coverage tool. On tjekditnet.dk, run by the Danish Agency for Digital Government, you can search any address to see which providers offer mobile service there and browse coverage maps by municipality, which is useful before booking a summer house on the west coast or a cabin on Møn.

Copenhagen, Aarhus, Odense and Aalborg are covered densely. The places to check are the dunes and heath of Thy National Park, the tip of Skagen where the Kattegat and Skagerrak meet, the cliffs of Møns Klint and the quieter lanes of Langeland, where you may fall back from 5G to 4G or lose the signal briefly between villages.

Denmark eSIM Plans Compared (2026)

Here is a comparison of the main Denmark eSIM plans against the leading international providers. Simsima offers plans on the local networks, with transparent pricing.

Unlimited data plans

Capped data plans

Prices move often, so the tables above are the reference on the day you buy. Simsima Denmark plans activate on arrival, when they first connect to a Danish network.

Data for a week in Copenhagen, Roskilde and Aarhus

A common first trip spends four days in Copenhagen, takes a day trip to the Viking Ship Museum in Roskilde, then heads to Aarhus by train for ARoS and the old town museum Den Gamle By.

• Rejseplanen journey planning, DOT Tickets for Copenhagen transit and DSB train tickets: about 0.5 GB
• Maps for walking and cycling routes, bike-share apps and restaurant bookings: about 1 GB
• WhatsApp, photos and short videos from Nyhavn and the harbor: 1 to 2 GB

That comes to roughly 2.5 to 3.5 GB, which a mid-size capped plan covers. Remote workers in Copenhagen cafés or anyone streaming on the train should look at the unlimited table, where speed is reduced after the daily high-speed allowance until the next day.

Setting up your Danish eSIM before you land at Kastrup

Installation takes about three minutes and is best done at home on your own Wi-Fi, a day or two before departure. You will receive a QR code and manual activation details by email after purchase. The profile sits dormant on your phone until you land in Denmark, at which point the mobile network selects it and data starts flowing. You keep your home line active for calls and SMS the entire time, and you can switch which line handles mobile data with a single tap in your phone's settings.

• Buy the Denmark eSIM plan online and check your email for the QR code
• On your phone, open Settings → Cellular/Mobile Data → Add eSIM (iPhone) or Settings → Network & Internet → SIMs → Download a SIM (Android)
• Scan the QR code or paste the activation details when prompted
• Label the new line as Denmark and keep your home line as the default for calls
• Set the Denmark line as the default for mobile data and turn off data roaming on your home line
• Before you fly, toggle airplane mode on and off to confirm the profile is installed correctly

What if the eSIM doesn't activate on landing?

If your line shows "No Service" after landing at Kastrup, Billund or Aalborg, run through this checklist before contacting support. First, confirm the Denmark line is enabled and set as the default for mobile data. Second, toggle airplane mode on for ten seconds and back off — this forces the phone to reselect a Danish carrier. Third, check that data roaming is enabled on the Denmark line specifically; travel eSIMs technically roam onto local networks, so this switch must be on even inside Denmark. Fourth, in Settings → Cellular → Network Selection, manually pick one of the networks listed in your plan's details if automatic selection fails. Finally, restart the phone. In practice, one of these steps resolves the vast majority of activation issues within a minute.

Apps that run Danish daily life

Denmark is close to cashless, and public transport is increasingly app-first. Rejseplanen plans door-to-door journeys across trains, metro, buses and many ferries nationwide. In the Copenhagen area, DOT Tickets sells mobile tickets for the metro, S-trains and buses, and the DSB app handles intercity trains. MobilePay is how many Danes pay each other and small stalls, though visitors usually just pay by card or phone.

All of these need data at the moment you use them, often on a platform or at a bike rack, which is where a working mobile connection matters more than hotel Wi-Fi.

Faroes, Greenland and other limits of a Danish eSIM

• No +45 number: the eSIM carries data only, so services that text a Danish number need your home line instead
• For EU visitors, it may duplicate an allowance your home plan already includes under roam like at home
• It does not cover the Faroe Islands or Greenland
• Working from a summer house on a laptop needs a plan that allows hotspot, and the phone must be unlocked to accept the profile

Malmö, Bornholm and the Swedish detour

Malmö is a short train ride across the Øresund Bridge from Copenhagen, and phones often switch to a Swedish network on the bridge itself. Bornholm, although Danish, is usually reached through Sweden: the bus or train from Copenhagen runs to Ystad for the ferry to Rønne. A Denmark-only plan stops working on the Swedish leg of that journey, so if Sweden or Norway is part of the trip, a regional plan that lists every country saves a second install. The Europe guide below compares the options.
