About this eSIM

Denmark is small, flat and densely populated, which is about the best set of conditions mobile data can ask for. You should expect to be connected essentially all the time, including on trains, on the bridges and on a bike halfway across Jutland. The genuine exceptions are a handful of small islands and the middle of a few sea crossings.

Getting online when you land

Install the profile at home over wifi so it is already sitting on the device when you travel. Kastrup has excellent free wifi if you need it, but building your arrival plan around an airport network is a habit worth breaking.

After landing, enable the profile and turn on data roaming for it. From Kastrup the metro into central Copenhagen takes about a quarter of an hour and you will want a working ticket app for it, so do this before you leave the terminal rather than on the platform.

Arriving over the Oresund bridge from Sweden works the same way, as does the train from Hamburg. Leave your usual SIM in for voice so the number on your booking still rings.

The networks you'll be on

Two operators are in the picture: 3 and TDC, both running 4G LTE and 5G where it has been rolled out.

That is real redundancy for a country this size, and it shows. Where one operator's coverage weakens, another's usually does not, so a roaming device has real choice about where to attach. It is the main reason Danish connectivity feels seamless in places that would be marginal elsewhere.

Practically: 5G across the cities and much of the motorway network, 4G everywhere else you are likely to be, and 3G as a rare fallback on the outer islands. Even the fallback carries maps and messages perfectly well.

Where coverage holds, and where it thins

Excellent: Copenhagen and the whole Zealand commuter belt, Aarhus, Odense, Aalborg and Esbjerg, the E45 and E20 motorways, the Great Belt and Oresund bridge crossings, the intercity rail lines, and the cycle route network that threads between towns.

Good: Skagen and the northern tip, the Legoland area around Billund, the west coast dune belt from Blavand up to Hvide Sande, the Mols and Djursland peninsulas, and Bornholm's towns including Ronne, Gudhjem and Svaneke.

Thinner: the smaller inhabited islands such as Aero, Fano, Samso and Laeso, where you will have service in the villages and less between them; the ferry crossings themselves, particularly the longer runs to Bornholm and out into the Kattegat, where you can spend a stretch of open water with nothing; the Wadden Sea tidal flats and the walk out to Mando; and a few deep stretches of the Rold Skov and Gribskov forests.

Copenhagen's metro tunnels are the other place to expect a drop. Load your route before you go down.

What you'll actually use data for here

Transport, cycling and payment, roughly in that order.

Danish public transport runs on apps. Journey planning across trains, buses, metro and the harbour buses lives in a phone, tickets are bought and shown the same way, and platform changes are announced there before they reach a screen. Trying to do it with paper is possible and consistently more annoying.

Cycling navigation is the other big one. Denmark's bike infrastructure is superb and the routes are not always intuitive, especially where a cycle path leaves the road and rejoins it three streets later. Turn-by-turn on a handlebar mount is how locals do it too.

MobilePay is the everyday payment habit here, used for everything from splitting a bill to buying strawberries at a roadside stall, though a contactless card covers you almost everywhere as a visitor. Either way, you want data.

Add to that opening hours, which are shorter than many visitors expect, and weather, which changes fast enough on the west coast to reshape an afternoon.

Before you fly

Cache offline maps of Copenhagen and of any island or coastal area on your route. The islands are the ones where it matters.

Screenshot your ferry and train bookings. Danish transport staff will happily read a picture on your screen, and a saved image survives the ferry crossing where a live app does not.

Bring a power bank sized for a full day. Cold weather, constant navigation and photography drain a battery faster than the same use would in summer, and a Danish winter afternoon gets dark early enough that you will be relying on your phone's torch as well.

Finally, if Bornholm is on the plan, download everything you need before boarding. The crossing is long and the middle of it is quiet in every sense.

Unlimited runs at full speed up to a fair-use limit, then continues slower.

Before you buy

Important to know

This is a data-only eSIM. It carries no calls or SMS on its own number.
Your existing number stays on your primary SIM, so calls and verification texts keep working.
Your phone must support eSIM, and some carrier-locked phones cannot install one.
Signal varies with location, terrain, congestion and your handset. Dense urban areas are consistently better served than remote ones.
5G only works where the host network has deployed it and your phone supports it. Everywhere else it falls back to 4G LTE.
The eSIM selects a host network automatically. You cannot pick or switch between them.
Unlimited plans run at full speed up to a fair-use limit, then continue at a reduced speed. Read the fair usage policy

Frequently asked questions

Does an eSIM work in Denmark?

Yes. Your Denmark eSIM connects automatically the moment you arrive, with no roaming fees and nothing to set up at the airport. The host networks it can use are 3, TDC. Coverage runs on 4G LTE and 5G where the network has rolled it out, and falls back to 4G elsewhere.

Do I get 5G in Denmark?

Yes, where it has been deployed. 5G runs on 3, TDC in Denmark, and your eSIM uses it automatically on a 5G-capable phone, dropping back to 4G LTE outside covered areas. No country is covered everywhere, so 5G availability varies by location.

Can tourists use MobilePay in Denmark?

Generally no. MobilePay requires you to live in Denmark and have a Danish phone number, a Danish CPR number and a Danish bank account with a card. A travel eSIM does not provide a Danish number, and the other requirements rule out most visitors anyway. Use a contactless card or phone wallet instead, which is accepted almost everywhere.

Does the old Rejsekort card still work in Denmark?

No. Rejsekort says the physical card can no longer be used for travel and is being phased out, and anonymous cardholders can get a refund of their balance. Use the Rejsekort app to check in and out, the Rejsebillet or DSB apps for pre-bought tickets, or the new Basiskort sold at kiosks and DSB 7-Eleven shops.

How do I get from Copenhagen Airport to the city centre?

Take metro line M2, which runs 24 hours a day from the airport through central Copenhagen to Vanløse. The airport is in fare zone 4, and the centre is in zones 1 and 2. Buy a ticket in the Rejsebillet, DSB or Rejsekort app, or get a City Pass or Copenhagen Card if you will travel a lot.

Does a Denmark eSIM work in the Faroe Islands or Greenland?

Do not assume so. Although both are part of the Kingdom of Denmark, they are separate destinations with their own mobile networks, outside mainland Denmark's. A plan for Denmark covers Denmark itself. If you are travelling on to the Faroes or Greenland, check what covers those places before you go.

How good is 5G in Denmark?

Very good. EU figures show 5G reaching 98% of Danish households, the highest share in the EU when reported, and 78.5% of mobile broadband subscriptions were on 5G in 2024. Coverage drops mainly in metro tunnels, on open water during longer ferry crossings such as the run to Bornholm, and in some forests and small islands.

How much data do I need for 7 days in Denmark?

For 7 days in Denmark, Viasimo sells 1 GB for $1.59 and unlimited data for $13.99. Our sizing recommendation, not a measurement: maps, messaging and the occasional lookup, about 1 GB a week; maps, social, photos and some browsing, about 3 to 7 GB a week. The data calculator on this site works it out from how you actually use your phone.

Know before you go

Denmark: what to know before you land

Denmark is one of the best-connected countries in Europe: EU figures put 5G coverage at 98% of households, and by 2024 more than three quarters of mobile broadband subscriptions were 5G. For visitors, the bigger change is that public transport has moved onto phones, with the physical Rejsekort card no longer valid for travel, while MobilePay remains closed to anyone without a Danish CPR number.

Copenhagen Airport to the city on the M2 metro

Copenhagen Airport (CPH) at Kastrup is on metro line M2, which runs to Vanløse through the centre and operates 24 hours a day, less often at night. Fares are zone-based across metro, buses and trains alike. The airport is in zone 4, and most central sightseeing is within zones 1 and 2.

You can buy tickets on your phone with the Rejsebillet, DSB or Rejsekort apps. Have one installed and set up before you land, since it is easier to enter card details on hotel wifi than on a crowded platform.

For longer stays, two passes are worth comparing:

City Pass: unlimited public transport within a chosen area for 24, 48, 72, 96 or 120 hours.
Copenhagen Card: the DISCOVER version includes public transport and entry to more than 80 attractions; the HOP version swaps regular transport for hop-on hop-off buses and covers 40-plus attractions.

Both passes are delivered digitally, so the pass, like your journey planner, lives on your phone. A flat battery means no ticket, and ticket inspectors on Danish transport issue fines. Carry a power bank on long days.

Rejsekort goes digital: the app replaces the blue card

For years visitors bought a blue Rejsekort travel card and tapped in and out. That has changed. Rejsekort says the physical card can no longer be used for travel and is being phased out, and holders of the anonymous card can claim a refund of any remaining balance. If you have an old card from a previous trip, do not count on it.

The options now:

Rejsekort app: create a profile and use the app to check in and out of journeys. You pay for the distance you actually travel.
Rejsebillet app: buy single tickets and commuter passes in advance, without checking in or out.
Basiskort: a new physical card. Anonymous versions are sold at kiosks, sales outlets and DSB 7-Eleven shops.

The check-in model has a practical catch for travellers. If your phone dies or loses data before you check out, the journey may not close properly. Check out promptly when you arrive, keep data on during journeys, and if you are only making a few trips, a pre-bought Rejsebillet ticket avoids the issue altogether.

Why MobilePay won't work for visitors

MobilePay is part of Danish daily life. It had more than 4.4 million users in Denmark in 2022, about three quarters of the population, and now operates as Vipps MobilePay after merging with Norway's Vipps, with each brand kept in its home market.

The catch for visitors is the sign-up rules. To use MobilePay in Denmark you need to live there and have a Danish phone number, a Danish CPR (civil registration) number and a Danish bank account with a card. A travel eSIM does not give you a Danish number, and even a local SIM would not solve the CPR and bank requirements.

What to do instead:

Use a contactless card or phone wallet. Denmark is heavily card-based and most shops, cafés and transport apps accept international cards.
For splitting bills with Danish friends, use a cross-border payment app you already have, or settle by card at the till.
At flea markets, farm stalls and small honesty-box sellers, MobilePay may be the main option. Carry a few kroner coins or notes as a fallback.

Denmark uses the Danish krone (DKK), not the euro.

5G coverage from Copenhagen to Skagen

Denmark's mobile figures are among the strongest in the EU. The European Commission's Digital Economy and Society Index reported 5G coverage for 98% of households, the highest in the EU at the time, with almost all of the harmonised 5G spectrum already assigned. By 2024, 78.5% of mobile broadband subscriptions were 5G, and Denmark had about 9.07 million mobile connections at the start of 2025, roughly 1.5 per person.

Your eSIM uses 3 and TDC, two of the country's main networks, both with 5G. Because 5G is so widespread here, the main limits are physical rather than network gaps: metro tunnels, the open water on long ferry crossings, and a few forest and island areas.

One boundary to plan around: the Faroe Islands and Greenland are part of the Kingdom of Denmark but have their own mobile networks, separate from mainland Denmark's. A Denmark plan covers Denmark itself. If your trip continues to Tórshavn or Nuuk, check coverage for those places separately. GOV.UK notes that travel between towns in Greenland is only by air, sea or dogsled, so connectivity there works very differently.

7-day itinerary

Seven days in Denmark: Copenhagen, Roskilde, Odense and Aarhus

A rail-based week that suits first-time visitors: three days in and around Copenhagen, including Kronborg Castle and the Louisiana museum, then west across the Great Belt to Roskilde, Hans Christian Andersen's Odense and the museums of Aarhus.

Length: 7 days
Bases: 3

When to go May to September brings long daylight and outdoor life, with July the busiest month; December has Christmas markets but only about seven hours of daylight.

Day 1 Copenhagen

Copenhagen: Nyhavn, Amalienborg and Tivoli

The M2 metro runs 24 hours from Copenhagen Airport to the city centre in about 15 minutes.

Take the M2 metro in from the airport. Walk Strøget to Nyhavn's painted harbour houses, then continue to Amalienborg, the royal residence, for the changing of the guard at midday. Cross to the Marble Church, then walk along the harbour to see the Little Mermaid statue. In the evening, visit Tivoli Gardens opposite Central Station when the lights come on.

Signal Strong 5G across central Copenhagen. The driverless metro has mobile coverage in its stations and tunnels, so maps keep working underground.
Day 2 Copenhagen

Copenhagen: Rosenborg, Christiansborg and Christianshavn

See the crown jewels at Rosenborg Castle and walk through the King's Garden. Head to Slotsholmen for Christiansborg Palace and climb its tower, which has free entry and one of the best views of the city. Cross the bridge to Christianshavn, climb the outside spiral of the Church of Our Saviour, then walk through Freetown Christiania and finish at Reffen street food on Refshaleøen.

Signal Excellent 5G throughout the city. In Christiania, ask before photographing residents or their homes, and keep your camera away where signs ask you to.
Day 3 Copenhagen

Louisiana and Kronborg Castle

About 35 to 45 minutes by train to Humlebæk, then about 10 minutes more to Helsingør.

Take the coastal train north to Humlebæk for the Louisiana Museum of Modern Art, with its sculpture park on the Øresund shore. Continue to Helsingør and visit Kronborg Castle, a UNESCO site and the setting for Shakespeare's Hamlet, including its casemates under the ramparts. Look across the water to Sweden, then take the train back to Copenhagen.

Signal Good 5G on the coastal line and at both sites. The underground casemates at Kronborg block signal.
Day 4 Odense

Roskilde and on to Odense

Copenhagen to Roskilde is about 25 minutes; Roskilde to Odense is about an hour by InterCity train.

Take a short train to Roskilde. Visit Roskilde Cathedral, a UNESCO site and burial place of Danish monarchs, then walk down to the Viking Ship Museum by the fjord to see five Viking ships recovered from the water. In the afternoon, take the train west over the Great Belt Bridge to Odense on the island of Funen.

Signal Strong coverage in Roskilde and on the main line, including over the Great Belt Bridge.
Day 5 Odense

Odense: Hans Christian Andersen's town

Spend the morning at H.C. Andersen's House, the museum and garden built around his birthplace, then walk the cobbled streets of the old quarter and see his childhood home nearby. Visit St Canute's Cathedral, where King Canute IV's remains lie in the crypt. In the afternoon, explore Den Fynske Landsby, an open-air village museum on the edge of town.

Signal Good 5G across Odense; the H.C. Andersen museum's underground galleries may weaken signal.
Day 6 Aarhus

Aarhus: ARoS, Den Gamle By and Moesgaard

Odense to Aarhus is about 1.5 hours by InterCity train.

Take an early train to Aarhus. Walk the rainbow-coloured circular walkway on the roof of ARoS Aarhus Art Museum, then visit Den Gamle By, an open-air museum of rebuilt Danish town houses from several centuries. In the afternoon, take a bus south to the Moesgaard Museum for its archaeology galleries, including the Grauballe Man, and its sloping grass roof.

Signal Good 5G in Aarhus city centre and at the museums.
Day 7 Copenhagen

Aarhus harbour and back to Copenhagen

About three hours by train from Aarhus to Copenhagen, or a short domestic flight from Aarhus Airport.

Walk the Latin Quarter and the riverside Aarhus Å in the morning, then see the new harbourfront at Aarhus Ø, where the Iceberg apartment buildings rise above the water. Take the train back towards Copenhagen; many services continue directly to Copenhagen Airport, which is convenient for an evening flight.

Signal Reliable 5G and 4G on the main rail line. Buy your Rejsebillet or DSB ticket in the app before boarding.

Staying connected on this route

Install the DSB and Rejseplanen apps before you travel; the old physical Rejsekort card no longer works for travel.
MobilePay needs a Danish bank account and CPR number, so pay by contactless card instead.
A Denmark plan does not cover the Faroe Islands or Greenland, which have their own networks.
