Denmark is an easy country to travel with a phone. Copenhagen runs on cards and apps, the distances are short, and coverage is strong almost everywhere, from the cycle lanes of the capital to the beaches of Jutland. With an EU SIM, Denmark is covered by Roam Like at Home. Visitors from the United States, the United Kingdom or Asia usually pay roaming by the day.
The surprises come at the edges: on the ferries, across the bridge to Sweden, and in the Faroe Islands and Greenland, which belong to the Danish realm but not to the EU.
Key facts for Denmark
- EU roaming: covered by Roam Like at Home
- Local networks: TDC, Telenor, Telia, Three (depending on the plan)
- Emergency numbers: 112; police non-emergency line 114
- Embassies: in Copenhagen and the neighbouring municipality of Gentofte
Copenhagen: the metro and paying by card
The metro runs around the clock and takes about 15 minutes from the airport to the city centre; tickets for the metro, buses and trains are sold in official apps and at machines. Denmark is close to cashless. Cards and phone payments are accepted almost everywhere, from bakeries to market stalls, and many visitors get through a whole trip without withdrawing any money.
Across the bridge to Sweden
Trains cross the Øresund Bridge from Copenhagen to Malmö in about 40 minutes. Sweden is in the EU, so EU plans keep working on the other side, but a travel plan for Denmark alone does not cover Sweden; for a day in Malmö, choose a regional plan that includes both countries. Along the coast north of Copenhagen, around Helsingør, phones can also pick up Swedish networks across the water.
Ferries and the sea
Ferries link Denmark with Norway, Sweden, Germany, the island of Bornholm and the Faroe Islands. Close to the coast your phone stays on land networks, but out at sea it can connect to the ship's own network, which falls outside Roam Like at Home and can be billed at high rates. Before the ship leaves port, switch off data roaming on your home SIM and keep it off until you are back in range of land.
The Faroe Islands and Greenland
The Faroe Islands and Greenland are part of the Kingdom of Denmark but not of the European Union, so the EU roaming rules do not apply there, and a plan for Denmark does not cover them. Both have their own travel plans. Coverage is good in the towns; between settlements, and above all in Greenland, where towns are not linked by road, it can be limited or absent.
Getting connected
EU SIM: your plan works in Denmark as it does at home. A travel eSIM is still useful if your tariff includes little data abroad, or for the Faroe Islands and Greenland.
SIM from outside the EU: install a travel eSIM before you leave. Its validity starts with the first connection in Denmark; your usual number keeps receiving texts and bank codes, and your apps run on the eSIM's data.
Danish prepaid SIMs are sold in supermarkets and kiosks.
Consular protection: who to call in Denmark
- 112 reaches an ambulance, the fire service and the police; 114 is the police line for matters that are not urgent.
- In the Capital Region, which includes Copenhagen, call 1813 before going to an emergency department when it is not life-threatening; nurses and doctors there tell you where to go.
- Embassies are in Copenhagen and the neighbouring municipality of Gentofte. The Telcomia app shows yours, with address and phone.
- Emergency phrases in Danish are ready to show on screen in the app.
Questions travellers ask about Denmark
Does my EU plan work in Denmark?
Yes, as at home. It may not on ferries at sea, in the Faroe Islands or in Greenland.
Does a Denmark plan work in Malmö?
No. For a trip across the bridge, choose a regional plan that includes Sweden.
Which networks does a Telcomia eSIM use in Denmark?
TDC or Telenor, and Telia or Three on some plans, with 4G and 5G where available.
Do I need cash in Denmark?
Rarely. Cards and phone payments are accepted almost everywhere.
The short version
From the EU, your plan covers Denmark on land; switch off data roaming on ferries and plan separately for the Faroe Islands and Greenland. From outside the EU, install a travel eSIM before you fly. Save 112, and 1813 if you are in Copenhagen.
