Our top 3 picks for Denmark
We evaluated 7 eSIM plans available for Denmark, comparing them on verified pricing, network coverage, top-up availability, and app quality. Five stood out.
HelloRoam
Best Value
$6.64
5 GB / 30 days
Pros: Lowest price per GB, fast activation, Denmark coverage on 3 and TDC. Cons: Newer brand, smaller community than Airalo.
Denmark runs 2 eSIM-ready networks, TDC (5G) and 3 (5G), and HelloRoam ranks first here because it roams on both: TDC for rural Jutland and Bornholm, 3 for the dense Copenhagen core. TDC is the national incumbent and holds 5G across Zealand, Funen and the southern Danish islands. Three (Hi3G Denmark) runs competitive 5G in Copenhagen and Aarhus.
Your eSIM picks the stronger of the 2 networks at each location. Both carriers include EU roaming across Scandinavia and the wider EU.
Coverage analysis
TDC and 3 (Tre) share Denmark's 5G backbone, with TDC holding stronger rural reach on the Jutland peninsula and 3 outperforming in Copenhagen's dense urban core. The S-tog commuter rail network around Copenhagen holds 4G in all tunnels and stations. The Öresund Bridge crossing to Malmö maintains unbroken 5G from TDC on the Danish side and hands off cleanly to Swedish networks mid-span.
Bornholm island in the Baltic has TDC 4G throughout, but the Faroe Islands and Greenland are separate territories with no TDC or 3 coverage.
Activation
Install your Denmark e-sim before landing at CPH (Copenhagen Airport Kastrup). Scan the QR code in Settings, then Mobile Data, then Add eSIM. Copenhagen Metro lines M1, M2, M3 and the Cityringen all carry 4G at underground stations.
Tethering is active on all 7 plans. EU roaming covers Sweden, Norway (EEA), Germany and the Netherlands at no extra cost.
Data usage tips
Rejseplanen (Danish transit app) for Copenhagen Metro and DSB train schedules uses under 10 MB per day. MobilePay Danish payment app uses under 5 MB per transaction. Copenhagen Card digital pass for 80+ museums downloads 30 MB and uses near-zero data.
Budget 500-700 MB per day in Copenhagen for maps, messaging, and social media. Streaming Danish Radio (DR) music uses 150 MB per hour on 3 and TDC.
eSIM plan pricing in Denmark
Denmark eSIM plans hold their value against the rest of Scandinavia. The 1 GB / 7-day plan costs $2.84. 3 and TDC GB runs $5.62 ($1.87/GB). Five GB costs $6.64 ($1.33/GB).
Ten GB hits $11.22 ($1.12/GB). The 20 GB plan at $21.35 is $1.07/GB. The 50 GB plan at $39.60 delivers the best per-GB rate of $0.79 across all 7 plans.
A 2 GB per day plan runs alongside the fixed tiers, and speed drops under fair-use terms once that daily allowance is spent. Verdict: the best eSIM for Denmark is HelloRoam at $6.64 for 5 GB. Saily's 5 GB costs $10.99, Airalo's 5 GB costs $11.00, and Holafly sells only a 5-day unlimited plan at $11.70.

Can I use an eSIM on the train from Copenhagen to Malmö?

Your Denmark eSIM data works in Sweden at no extra cost. The 20-minute train journey holds 4G or 5G throughout, so you can stream, message, or make video calls the entire way.
How much does an eSIM for Denmark cost?
+

How do I activate an eSIM in Denmark?
+
The best eSIM for Denmark is HelloRoam. Install the Denmark eSIM before you fly. Open Settings, tap Mobile Data, then Add eSIM, then scan the QR code. Your phone registers on TDC or 3 by itself once you land at CPH, with no store visit and no paperwork. Copenhagen Metro holds 4G underground. Tethering and EU roaming switch on across all 7 plans without any extra step.
How much data do I need in Denmark?
+
The best eSIM for Denmark is HelloRoam. A 4-day Copenhagen trip uses 3-4 GB: Rejseplanen, Copenhagen Card, and Instagram at about 700 MB per day. A week adding Aarhus and Odense by DSB train needs 5-7 GB. Remote workers at CPH digital nomad spaces should budget 10 GB or more per week at 1-2 GB per video call hour on 3 and TDC.
Which networks do eSIMs use in Denmark?
+
The best eSIM for Denmark is HelloRoam. Denmark eSIMs connect to 2 carriers: TDC (5G) and 3 (5G). TDC covers all Danish islands including Bornholm and leads in national rural coverage. Three performs strongly in Copenhagen and Aarhus urban areas, and your eSIM picks the stronger signal automatically. Both carriers deliver 5G in central Copenhagen and key Jutland cities.
Does a Denmark eSIM cover the Faroe Islands?
+
The best eSIM for Denmark is HelloRoam. The Faroe Islands are a self-governing territory with their own operators, Faroese Telecom and Hey, so neither of Denmark's 2 eSIM carriers reaches them. A separate Faroe Islands plan or home-carrier roaming is required. Greenland works the same way through Tusass. Confirm Faroe coverage with your provider before buying a Denmark eSIM for a trip that includes either territory.
Does a Denmark eSIM include EU roaming for Sweden and Norway?
+
The best eSIM for Denmark is HelloRoam. Denmark eSIM plans on TDC and 3 include EU roam-like-home rights across all 27 EU member states. Sweden is in the EU, so your Denmark data works there at no extra charge. Norway sits in the EEA and takes part in the same roaming rules, so it is covered too. Travelers crossing the Öresund Bridge to Malmö or taking the ferry to Oslo pay nothing extra.
Does my phone support eSIM in Denmark?
+
The best eSIM for Denmark is HelloRoam. Denmark eSIM plans run on TDC and 3, and both work with any modern eSIM-capable phone: iPhone XS or newer, Pixel 3a or newer, Galaxy S20 or newer. Your device must be carrier-unlocked. Dual-SIM models let you keep a home SIM active alongside the TDC or 3 Denmark eSIM. Confirm eSIM support in Settings, then General, then About before buying.
Can I use a Denmark eSIM for MobilePay?
+
The best eSIM for Denmark is HelloRoam. Tourists without a Danish number can use the MobilePay app in limited mode at some merchants. Your Denmark eSIM data connection covers every digital payment that needs only internet, including Google Pay and Apple Pay at Danish terminals. MobilePay QR codes at markets and cafes work without a Danish number. The 3 GB plan at $5.62 covers a long weekend of this.
Can I top up my Denmark eSIM if I run out of data?
+
The best eSIM for Denmark is HelloRoam. All 7 Denmark eSIM plans support top-up through your provider's app. Purchase a data add-on and it activates on the same eSIM profile within minutes. No new QR scan is needed. Start with the 3 GB plan at $5.62 for a Copenhagen long weekend and top up to 5 GB if you extend to Helsingore (Kronborg Castle) or Skagen.
