Free eSIM for Denmark 
3 GB of free mobile data across Denmark — from Copenhagen's bike lanes to Bornholm's cliffs. Install on the plane, step off at CPH already online, and skip the Yousee counter at the metro entrance.
Free for new users · Credit card for identity verification only — never charged · Valid 3 days
Why an eSIM beats a Danish prepaid
Denmark is cycling country, and most travellers discover that quickly — you'll be unlocking Donkey Republic bikes and checking Google Maps far more than you planned. Lebara and Lycamobile kiosks exist around CPH but require a CPR-style address or passport check for full activation, and the standard 1 GB for 49 DKK tourist plans burn out fast when you're using Maps all day on a bike. 99esim gives you 3 GB free, activates on the plane, and works on your second device (laptop, tablet) if your phone is a dual-eSIM model.
- No passport check at a Danish telco counter
- Works seamlessly across the Øresund Bridge to Sweden
- Ideal for Donkey Republic + Google Maps bike navigation
- 3 GB handles a long weekend in Copenhagen plus Bornholm
How Danish networks handle 99esim
99esim's primary host in Denmark is TDC/Yousee — the former state operator with the deepest coverage, especially on Jutland and Bornholm. 5G is live across Copenhagen, Aarhus, Odense, Aalborg and most of Zealand's motorway network. Denmark has among the fastest average mobile speeds in Europe thanks to early 5G-SA rollouts in 2021.
Arriving at a Danish airport
CPH handles the vast majority of international traffic; Billund and Aalborg round out regional service. All have full 5G at gates and on airport trains. Your eSIM connects instantly, which matters for activating the Rejsekort transit card app before you reach the platform.
The M2 metro from Terminal 3 reaches Kongens Nytorv in 14 minutes — full 4G/5G the entire tunnel journey thanks to DAS. The Øresund train goes on across to Malmö in 35 minutes if you're skipping Copenhagen.
Main gateway for Legoland and central Jutland. The 43 and 143 buses to Vejle and Aarhus both stay connected on E20. 5G throughout the compact terminal.
6 km from central Aalborg. Bus 2A runs every 20 minutes and keeps signal across the fjord bridge. Popular for northern Jutland beach trips to Skagen.
40 km from Aarhus city. Airport shuttle bus to the main train station takes 45 minutes — signal holds along Route 15. Many travellers fly into Billund or CPH instead.
Tiny island airport on the Baltic. Only domestic flights plus a few Berlin and Stockholm routes. Signal is reliable across the island; bus 1 into Rønne town takes 15 minutes.
Where your free eSIM works best
What 3 GB actually gets you in Denmark
Denmark rewards biking travellers — maps are your main data hog. Here's how 3 GB realistically splits for a Copenhagen + Bornholm trip:
Denmark-specific travel tips
Bike-friendly Copenhagen and data efficiency
Google Maps bike mode is the single biggest data consumer for Copenhagen visitors — you'll unlock Donkey Republic bikes or rent from Baisikeli and cycle everywhere. Download central Copenhagen offline maps before you arrive to cut navigation data in half, and use your eSIM only for live re-routing when needed.
Copenhagen Metro coverage
M1, M2, M3 Cityringen and the new M4 all have full DAS — the Cityringen is driverless and automated, with uninterrupted 5G throughout. The M1 out to Vestamager and the new M4 down to Sydhavn both stay connected in every tunnel. Best subway signal in Scandinavia.
Bornholm remoteness
The 'sunshine island' sits 160 km east of Copenhagen in the Baltic — reachable by ferry from Ystad (Sweden) or direct flight. Rønne and Svaneke have full 4G. The interior forests (Almindingen, Paradisbakkerne) can thin out. Northern cliffs near Hammershus are well covered.
Øresund crossing to Sweden
The bridge-plus-tunnel to Malmö takes 35 minutes by train or car. Your eSIM hands off automatically from a Danish operator to a Swedish one mid-bridge — data stops for a few seconds. The 4 km undersea tunnel on the Danish side has no mobile signal.
Jutland west coast wind
The long Jutland coast facing the North Sea is well covered by TDC, but the dunes and beach huts of Blokhus, Løkken and Skagen can have patchy signal right on the sand due to low tower density. Signal returns the moment you walk off the beach.
Travelers who used 99esim in Denmark
"Five days biking around Copenhagen with Donkey Republic and Google Maps. eSIM held everywhere — Refshaleøen, Amager, Nyhavn, the Lakes. Zero dropouts."
"Weekend trip to Bornholm via the Bornholmerlinjen ferry from Ystad. eSIM worked on the crossing most of the way and the whole time on the island."
"Copenhagen for a conference then across to Malmö by train. The handoff on the Øresund was the smoothest border crossing I've ever had on a eSIM."
Frequently asked — Denmark edition
Does the eSIM work on the Copenhagen Metro?
Yes on all four lines. Denmark's Metro has had DAS since 2015 on the original M1 and M2, and the newer M3 Cityringen and M4 Sydhavn extensions came with 5G-ready infrastructure from day one. Expect consistent 4G/5G in every tunnel section.
Will it work on Bornholm?
Yes. The island is served by TDC and Telia — Rønne, Svaneke, Gudhjem, Allinge and Hammershus all have full 4G. Deep forest trails in Almindingen and the rocky interior can have thin signal, but you'll never be more than a 20-minute walk from a tower.
Can I use it on Danish trains (DSB)?
Yes. The Copenhagen–Odense–Aarhus main line has strong 5G through most of the route. The short Storebælt tunnel between Zealand and Funen briefly drops signal — under 4 minutes. DSB also provides free WiFi on most intercity trains, but your eSIM is usually faster.
Does it cover the Faroe Islands or Greenland?
No. The Faroes and Greenland use separate carriers (Føroya Tele and Tusass respectively) that are not in the 99esim European bundle. Denmark proper including Bornholm is fully included.
Is 5G included in the free plan?
Yes. Denmark has among the densest 5G coverage in Europe — if your device supports 5G, the eSIM uses it automatically wherever available. Data counts the same rate as 4G. You'll see 5G SA (standalone) in Copenhagen and Aarhus.
What happens after the free 3 GB?
Top up in the 99esim app in seconds — Denmark add-ons start at around €2.99 for 1 GB. No auto-renewal, no card surprises. Your 30-day window continues either way.
