Key takeaways
Denmark has three national carriers delivering reliable 4G and expanding 5G across the entire country, including cycling routes and remote islands like Bornholm. A Roamix Denmark eSIM connects you to the best local network the moment you land in Copenhagen, with no roaming fees. Budget 5 to 8 GB for a two-week trip, and note that unlike most European airports, Copenhagen has no dedicated carrier counter, making a pre-installed eSIM the smart move.
- TDC leads on nationwide coverage and has been rated Denmark's best network for over a decade, with 99% 5G population reach.
- A Roamix eSIM activates automatically on arrival at Copenhagen Airport, avoiding the lack of tourist SIM counters.
- EU/EEA Roam Like At Home rules apply to EU SIMs in Denmark, making Roamix cost-effective for non-EU visitors.
- MobilePay is the dominant payment app in Denmark and requires a connected phone to book bikes, pay at markets and split bills.
- Cache offline maps before cycling routes like the Marguerite Route and island drives, where signal can be intermittent.
Best way to get data in Denmark
For non-EU visitors to Denmark, a Roamix eSIM is the most practical option given the absence of airport SIM counters, with local network speeds and no surprise roaming charges.
| Option | Best for | Good to know |
|---|---|---|
| Roamix eSIMRecommended | Best for: Most travellers | Instant activation on a local network, no roaming bill and nothing to collect at an airport kiosk that does not exist at CPH. |
| Local physical SIM | Best for: Long stays needing a Danish number | Requires a visit to a city-centre carrier store and ID. No tourist SIM counter at Copenhagen Airport. |
| Pocket wifi | Best for: Groups sharing one connection | Another device to charge, and you must return it at the end of the trip. |
| Carrier roaming | Best for: EU SIM holders using Roam Like At Home | EU/EEA SIMs can roam in Denmark at home rates. Non-EU carrier roaming can be expensive. |
Free wifi is widely available in hotels, cafes and libraries across Denmark, but public networks are unsecured for banking. Mobile data is more reliable on cycling routes and ferries.

How to set up a Denmark eSIM
A Roamix Denmark eSIM is best installed over wifi before departure. It activates automatically when you connect to a Danish network on arrival, so you land already online at Copenhagen Airport without needing a SIM kiosk.
- 1
Buy your plan on the Roamix Denmark eSIM page before departure.
- 2
Scan the QR code or tap to install the eSIM over wifi.
- 3
Label it Roamix and keep your home SIM as primary for calls and texts.
- 4
Enable data roaming for the Roamix line only.
- 5
Land in Denmark and the eSIM connects automatically to a local carrier.
Works on eSIM capable phones including iPhone XS and newer, Google Pixel 3 and newer, and recent Samsung Galaxy models. The phone must be carrier unlocked.
Roamix sets the correct APN automatically on most devices. If data does not start, apply the APN from your order and toggle airplane mode.
No data on arrival usually means data roaming is off for the Roamix line. Check settings, select the network manually and restart.
Visa and entry for Denmark
Denmark is a Schengen Area member. Citizens of the EU, EEA, Switzerland and many other countries enter without a visa for up to 90 days. From 2025, most nationalities not currently requiring a Schengen visa will need to apply for an ETIAS travel authorisation before visiting.
- eVisa or ETA
- ETIAS (European Travel Information and Authorisation System) is required from 2025 for visa-exempt non-EU nationals travelling to the Schengen Area, including Denmark. Applications are made online and cost around 7 EUR.
- Passport validity
- Your passport should be valid for at least 3 months beyond your planned departure date from the Schengen Area.
- Onward ticket
- Proof of onward travel and sufficient funds may be requested at the border.
Keep your ETIAS approval and travel documents accessible on your phone. Use your Roamix eSIM at the border if you need to pull up digital documents.
Entry rules change. Confirm current Schengen requirements with the Danish Ministry of Foreign Affairs before booking.

Getting around Denmark
Denmark combines excellent intercity rail with a world-class cycling infrastructure and good ferry connections between islands. Data is useful for every mode.
Train and metro
DSB intercity trains connect Copenhagen, Aarhus, Odense and Aalborg. Copenhagen has a Metro and S-tog network. The DOT app gives real-time arrivals and mobile tickets.
Cycling
Denmark is one of the world's top cycling destinations. Copenhagen has an extensive cycle lane network and dockless bike rentals. The Marguerite Route and cross-country cycling paths use apps for navigation.
Ferry
Inter-island ferries connect Funen, Bornholm, the South Danish islands and smaller island communities. Book tickets and check schedules using ferry operator apps with Roamix data.
Car rental
Ideal for exploring Jutland's heathland, coastal national parks and the smaller islands. Live navigation and offline map packages are recommended for rural routes.
The Copenhagen Metro runs 24 hours and accepts contactless and mobile payments. Download the DOT app for real-time departures across Metro, S-tog and regional trains.
Money and payments in Denmark
Denmark is one of the most cashless societies in the world. MobilePay is used for everything from market stalls to splitting a restaurant bill, making a connected phone more important than carrying DKK.
- Cards and cash
- Cards and contactless are accepted almost everywhere. MobilePay dominates peer-to-peer payments. Carry a small amount of DKK for very small purchases in rural markets only.
- ATMs
- ATMs are available in towns and cities. Use bank ATMs to avoid high fees and decline dynamic currency conversion.
- Payment apps
- MobilePay is the dominant app and requires a Danish phone number or bank account. Apple Pay and Google Pay are widely accepted at point of sale.
- Tipping
- Tipping is not expected in Denmark. Service is included in restaurant prices. Rounding up the bill or leaving 10% is appreciated but entirely optional.
Daily budget
Budget travellers spend around 500 to 700 DKK a day, mid-range 900 to 1,400 DKK. Copenhagen is one of Europe's pricier cities.
Local tips for Denmark
- Language
- Danish is the official language, but virtually all Danes speak excellent English. You will rarely encounter a language barrier as a tourist.
- Food
- Denmark has earned a global reputation for New Nordic cuisine. Look for smorrebrod open sandwiches, pastries from local bagerier, fresh seafood and world-class restaurants along Nordhavn and in the Meatpacking District.
- Plugs
- 230V, Type C and K plugs

Safety and health in Denmark
Denmark is one of the safest countries in the world for tourists. The main concern is petty theft in busy Copenhagen areas like Stroget and Nyhavn.
- Stay reachable
- Keep your Roamix eSIM active so you can call 112 in an emergency and use Google Maps to navigate back to well-lit areas if you get lost on an evening out.
- Health
- Healthcare is excellent. EU citizens with an EHIC card receive treatment at Danish hospitals. Non-EU visitors should carry travel insurance.
- Tap water
- Tap water is safe and excellent quality across Denmark.
Networks and coverage in Denmark
Denmark's three national carriers, TDC, Telenor and Telia, deliver 4G coverage to virtually the entire population and 5G across all major cities. TDC and Telenor share infrastructure across most of their networks, giving consistent coverage from Copenhagen to rural Jutland. A Roamix Denmark eSIM connects to the strongest available local network the moment you land, with no roaming fees.
TDC
Rated Denmark's best network for over ten years by the Danish Technological Institute, with 99% 5G population coverage and the best rural and island reach including Bornholm and the Danish islands.
Telenor Denmark
Shares infrastructure with Norlys through TT-Netvaerket, covering 99.9% of the population on 4G with strong city performance and a growing 5G footprint.
Telia Denmark
Awarded fastest download speeds and highest 5G availability in Copenhagen in 2025, with solid coverage across Zealand and Jutland.
- Typical speeds
- Urban 5G delivers 80 to 200 Mbps, with 20 to 60 Mbps on 4G in towns and rural areas.
- 5G
- 5G is live across Copenhagen, Aarhus, Odense and Aalborg, with national expansion ongoing.
For cycling trips and island hopping, TDC gives the most consistent signal. For speed in Copenhagen and Aarhus, Telia edges ahead. Either way, a Roamix eSIM connects you to the best available network without any physical SIM swap.
Denmark is compact and coverage is excellent nationwide. Remote stretches of northern Jutland, small uninhabited islands and some forest areas can drop to 4G or limited signal, but this affects very few tourist routes. Danish networks use standard European LTE bands and 5G NR on 700 MHz and 3500 MHz, compatible with virtually any recent unlocked iPhone or Android device.
Where to go in Denmark
Denmark rewards curious travellers with world-class city culture in Copenhagen, Viking history across Jutland, stunning coastal scenery and island escapes. Distances are short and the country is easily explored by train, bike or car, all of which benefit from a connected eSIM.
Best time to visit
May to August for cycling, outdoor dining and long daylight hours. September and October for quieter sightseeing and autumn colours. December for Christmas markets in Copenhagen and Tivoli.
Copenhagen and Zealand
Denmark's vibrant capital anchors the island of Zealand, combining Nyhavn harbour, Tivoli Gardens, world-class restaurants, the Louisiana Museum and the historic Kronborg Castle at Helsingor.
- Nyhavn
- Tivoli Gardens
- Kronborg Castle
- Louisiana Museum of Modern Art
- Christiania
Excellent 5G coverage across all of Copenhagen including Nyhavn, Frederiksberg and the Metro network. TDC and Telia both deliver fast speeds throughout Zealand and the Oresund bridge corridor to Sweden.
Jutland
The Danish mainland, stretching from the German border to the northern tip at Skagen, offers heathland national parks, the art city of Aarhus, LEGOLAND in Billund and the dramatic Skagen light where the North Sea meets the Kattegat.
- Aarhus ARoS Museum
- Skagen
- LEGOLAND Billund
- Ribe
- Wadden Sea National Park
TDC delivers strong 4G and 5G coverage across Jutland from Aarhus and Aalborg to the Wadden Sea coast. Remote heathland areas inside Rebild National Park can drop to 4G but remain usable.
Funen and the South Danish Islands
The island of Funen, birthplace of Hans Christian Andersen, sits between Jutland and Zealand and is surrounded by a cluster of smaller islands connected by bridges and ferry routes, offering quiet cycling and sailing country.
- Odense Hans Christian Andersen Museum
- Egeskov Castle
- Aero island
- Svendborg
- Langeland
Good TDC 4G coverage across Funen including Odense and the southern islands of Aero and Langeland, though the smallest islands and ferry routes can drop signal briefly.
Bornholm
Denmark's sunshine island in the Baltic, with distinctive round churches, smokehouses, white sandy beaches at Dueodde, dramatic sea cliffs at Hammeren and an artisan food culture that draws visitors from across Scandinavia.
- Hammershus Castle Ruins
- Dueodde Beach
- Gudhjem
- Round Churches
- Almindingen Forest
TDC provides reliable 4G and growing 5G coverage across the main towns of Ronne, Nexo and Allinge, with some gaps on remote forest trails and small offshore rocks.
North Jutland and the National Parks
The wild northern tip of Denmark, where Skagen sits at the junction of two seas, Rebild National Park offers heathland walking, and the Thy and Mols Bjerge national parks add coastal dunes and rolling hills.
- Skagen Grenen
- Rebild National Park
- Thy National Park
- Rubjerg Knude Lighthouse
- Mariager Fjord
TDC covers Aalborg, Hjorring and Frederikshavn well, with 4G reaching most of Thy National Park and the Skagen peninsula. The most remote dune areas and offshore islands have limited signal.
Off the beaten path
Denmark's northernmost point, where the North Sea and Kattegat visibly collide in churning waves just metres apart, surrounded by the golden light that made Skagen famous among 19th-century painters.
Signal: TDC covers the Skagen town and the car park, but the sandbar tip of Grenen where the two seas meet can have intermittent signal depending on conditions.
A 19th-century lighthouse slowly being consumed by coastal sand dunes, now perched dramatically on the cliff edge above the North Sea after being moved 70 metres inland in 2019 to save it from falling.
Signal: TDC covers the road access and parking area, with good signal at the lighthouse itself on the cliff edge.
Denmark's most dramatic natural feature, a 6 km stretch of brilliant white chalk cliffs rising 128 metres above the Baltic Sea, with fossils from the Cretaceous period and views across to Sweden.
Signal: TDC covers the GeoCenter visitor area, but the clifftop hiking trails and staircase down to the beach drop to limited or no signal, so download trail maps first.
Rated among Scandinavia's finest beaches, with impossibly fine white sand that was historically used in hourglasses around Europe, backed by pine forest and reaching over 10 km along the southeast coast of Bornholm.
Signal: TDC covers the car park and beach access road, with reasonable signal along the main beach. Remote dune areas further along the coast can drop out.
Denmark's westernmost island, connected by a causeway across the Wadden Sea tidal flats, with Europe's widest sandy beach at Lakolk where cars drive directly onto the sand, and a UNESCO-listed tidal ecosystem.
Signal: TDC covers Romo town and the causeway road, with reasonable signal on the main beach. The vast tidal flats and remote western beach stretches can go off-grid.
The largest medieval castle ruins in Northern Europe, perched on a 74-metre basalt cliff on the northwestern tip of Bornholm, with sweeping sea views and a history stretching back to the 13th century.
Signal: TDC covers the Hammershus visitor centre and the main ruin site well, with good signal for navigation across the rocky headland.
The Danish Lake District, centred on Silkeborg, offers canoe and kayak routes through a chain of glacial lakes, the paddle steamer Hjejlen on the world's oldest scheduled steamer service, and access to the Himmelbjerget hilltop.
Signal: TDC covers Silkeborg town and the main lake areas well, with 4G available on kayak routes and good signal along the Gudenaa River.
Consistently ranked among the world's greatest art museums, set in a clifftop villa north of Copenhagen where Giacometti bronzes stand in a sculpture park directly above the Oresund strait with views of Sweden across the water.
Signal: Strong TDC coverage throughout the museum and sculpture garden, with good signal for the waterfront terraces overlooking the Oresund strait.
One of the largest uninterrupted tidal flat systems in the world and a UNESCO World Heritage Site, home to millions of migratory birds, grey seals and a dramatic tidal landscape that transforms twice daily.
Signal: TDC covers the gateway towns of Ribe and Esbjerg, with 4G available on guided walks. The tidal flats themselves have no signal, so download guides in advance.
The most romantic of the South Danish islands, where the perfectly preserved 18th-century merchant town of Aeroskobing glows with coloured half-timbered houses, and the island is ideal for cycling, kayaking and sailing.
Signal: TDC covers the main towns of Aeroskobing, Marstal and Soby, with 4G for most of the island. Some remote lanes and ferry approaches can drop signal briefly.
