Denmark eSIM and SIM cards: nothing to decide but the price

The short version, twice over

If you are travelling from another EU country, stop here. Roam-like-at-home covers Denmark, your allowance follows you, and buying a Danish eSIM on top would be paying for a worse version of what you already have. Confirm your roaming fair-use cap before you fly and that is the whole job.

If you are travelling from outside the EU, there is a second short version: this is one of the easiest countries in the world to get this right, because Denmark has removed the hardest part of the decision.

What 100% coverage does to the argument

Most of these pages spend their length on network choice, and for good reason. In most countries the cheap eSIM and the good eSIM are on different networks, and the gap between them shows up somewhere expensive — a mountain pass, an island, a long rural road.

Denmark achieved 100% population coverage for both 4G and 5G. That is a global benchmark; very few countries have matched it. Average download speed sits around 104 Mbps.

There are four operators. TDC, formerly the state monopoly, has the longest-established rural infrastructure. Telia and Telenor pool their masts in a joint venture, the TT-Network, which means the two of them share one physical footprint rather than competing with two thinner ones. Telia leads on 5G speed and availability. 3 Denmark is the fourth.

Every one of the eSIM providers we track sells on at least one of these. Given the coverage picture, the practical answer to "which Danish network should I choose?" is that it is not a question worth your time. Nothing in the Danish data suggests a traveller would notice the difference.

There is one caveat, and it is a definitional one rather than a coverage claim. Population coverage measures where people live. It does not measure the sea. Denmark has a lot of water in it — the crossing to Bornholm, the ferries around the Baltic and the Kattegat — and mid-crossing dropouts are the standard exception to any population coverage figure anywhere in the world. Nobody publishes a number for that, so neither will we. Expect it, and download your maps.

So it is a price contest, and it is not close

With coverage neutralised, Denmark becomes a simple comparison. Here is what the same plan costs across the three metered providers.

An earlier version of this page said Nomad was cheapest at every size it sells, on a 50 GB figure it quoted at $0.58 a gigabyte. Those Nomad figures had never been read off Nomad's own site. They have been now, on 18 August 2026, and several were wrong: we had understated the 5 GB by $3.50 and the 50 GB by $16, and overstated the 20 GB by $2. The corrected prices are in the table above. Airalo's column was wrong too, and wrong in Airalo's favour once corrected — its 5 GB is $11, not $14.

The corrected picture is a split rather than a sweep. Nomad wins the middle of the ladder: $16 against Airalo's $17.50 at 10 GB, and $20 against $27.50 at 20 GB, which is the one substantial gap on the board. Airalo wins the ends: $11 against $12.50 at 5 GB, and $35 against $45 at 50 GB. Airalo's 50 GB is the cheapest data in Denmark at $0.70 a gigabyte; Nomad's best rate here is $0.90. For comparison, Germany's floor is $0.64 and Greece's is $0.62, both of them Nomad plans — Denmark is simply not one of Nomad's cheap markets.

Nomad also sells below 5 GB, contrary to what this page previously said: 1 GB over seven days at $4.50 and 3 GB over thirty at $9. Saily's 1 GB over seven days at $3.99 is still the cheapest entry point, and it is now a checked price, but understand what you are agreeing to at that size: $3.99 per gigabyte, close to six times Airalo's 50 GB rate. Small plans are a packaging tax everywhere and Denmark is no exception.

The Airalo and Nomad rows above were read off those providers' own sites, on 13 and 17 August 2026 respectively. Saily's were read off Saily's own site on 18 August 2026, and they came back lower than the figures we used to publish at every size above 1 GB.

One thing the verified Nomad ladder shows that the old figures hid: it is identical, to the cent, in thirteen countries — Belgium, Bulgaria, Czechia, Denmark, Hungary, Iceland, Ireland, Netherlands, Norway, Romania, Slovakia, Slovenia and Sweden all get $4.50 / $9 / $12.50 / $16 / $20 / $45. That is a seller's tiering policy, not a reflection of what data costs in Denmark.

Two rows that contradict each other

Denmark's unlimited pricing has a problem you should know about before you buy.

Holafly's ladder is not monotonic. The 25-day plan sits at $68.90 while the 30-day plan sits at $59.90 — five fewer days for $9 more. We have flagged that 25-day row as suspect rather than reporting it as a finding, because it is more likely to be a stale or mis-captured figure than a real price.

An earlier version of this page also reported duplicate Holafly rows at five and ten days, priced $19.00 and $36.90 alongside $18.90 and $27.90. Those duplicates are no longer in our data; the ten-day plan is $27.90 and the fifteen-day is $36.90, which is what the second figure almost certainly always was. We should not have presented a duration error of our own as a pricing inconsistency of Holafly's.

Holafly's Danish rows remain unverified — nobody has read them off Holafly's checkout on a recorded date. The instruction does not depend on the explanation: before buying unlimited data for Denmark, read the duration column and the price column together, and check whether a longer plan costs less than the one you were about to buy. In Denmark, sometimes it does.

For what it is worth, the best per-day rate in the Danish unlimited range is the 90-day plan at $99, which comes out at $1.10 a day. The 30-day plan is $2.00 a day. Everything under two weeks sits between $2.46 and $6.90.

Does unlimited make sense here at all?

Rarely on metered grounds. Airalo's 50 GB at $35 gives you more data than almost any traveller uses in a month, for well under Holafly's indicative 30-day unlimited at $59.90 and Airalo's own verified unlimited month at $71. Nomad's 10 GB at $16 covers a normal week comfortably for less than any ten-day unlimited plan on the board.

Where unlimited is the answer, Nomad is now the verified place to buy it: $11 for three days, $18 for five, $25 for seven and $33 for ten, each of them under Airalo's $11.50, $19.50, $27 and $35. Holafly's verified ten-day at $36.50 is lower still, but it has not been checked.

Unlimited earns its keep in Denmark in two situations: you are tethering a laptop and working, or you genuinely cannot predict your usage and would rather pay for the certainty. Neither is a majority case.

What we would do

1. EU contract? Nothing. Done.
2. Week in Copenhagen from outside the EU? Nomad 10 GB at $16, or Airalo's 5 GB at $11 if a week of maps and messaging is the whole job. Ignore everything about networks.
3. Longer, or several devices? Airalo 50 GB at $35. At $0.70 a gigabyte it is the cheapest data on this page — Nomad's 50 GB is $45 — and it makes hotspotting viable, so confirm the provider allows it first. If 20 GB is enough, Nomad's $20 is the best value on the board.
4. Considering unlimited? Compare it against Airalo's 50 GB before you commit, and check the durations against each other.
5. Considering a local SIM? Danish prepaid SIMs need passport registration and run around $13 at the airport. Against a $16 eSIM that works when you land and asks for no documents, the case is weak.

Cross-country provider pricing is in the cheapest eSIM comparison, and the physical-SIM detail lives on the Denmark SIM card guide.
