Denmark data prices and the cheapest honest route

If your plan is European, skip the rest of this page

Denmark is in the EU. An EU or EEA phone plan roams here on your home allowance under roam-like-at-home, so a Swedish, German or Irish SIM already works in Copenhagen at no extra cost. Check your operator's fair-use data cap, which is the only limit likely to matter on a short trip, and buy nothing.

That leaves visitors from the UK, the US, Canada, Australia and elsewhere, for whom Danish data has to be bought outright. The good news is that it is cheap by European standards.

Where the floor actually is

The cheapest gigabyte in Denmark is not at the bottom of the ladder but the top. Airalo's 50 GB for 30 days is $35, which works out at $0.70 a gigabyte, and that price was read off Airalo's own site on 13 August 2026.

An earlier version of this page carried a lower number, which it flagged as indicative because nobody had re-read it off Nomad's site: a 50 GB month at $0.58 a gigabyte. It has been read now, on 18 August 2026, and it was understated by $16. Nomad's Danish 50 GB is $45 — $10 above Airalo's, and $0.90 a gigabyte. The $0.70 floor stands, and it is Airalo's.

Nomad is not out of the Danish picture, though. It is genuinely cheaper in the middle of the ladder, and those figures are checked too.

The pattern the old version of this page reported — Nomad a couple of dollars under Airalo at every shared size — was an artefact of prices we had never checked. The real pattern is a split. Nomad wins the middle by a wide margin at 20 GB, $20 against $27.50, and by $1.50 at 10 GB. Airalo wins both ends: $11 against $12.50 at 5 GB, $35 against $45 at 50 GB.

The bottom of the ladder is where value disappears. Saily's 1 GB for a week at $3.99 is nearly six times the country's floor rate. For four days in Copenhagen, Airalo's verified 3 GB for three days at $7.50 or 3 GB for seven days at $8 do the job for less than a round of coffees.

Unlimited, and when the arithmetic turns

Holafly sells short unlimited plans that are genuinely useful at the very short end: $6.90 for a single day and $20.50 for five, both verified. A one-day plan at that price is hard to beat for a layover.

Over a week or more the metered plans take over. Holafly's indicative 30-day unlimited is $59.90 and Airalo's verified equivalent is $71, against $35 for 50 GB across the same month. Nomad's unlimited stops at ten days, but it is the cheapest verified way to buy uncapped data over shorter windows: $11 for three days, $18 for five, $25 for seven and $33 for ten, each under Airalo's. Fifty gigabytes covers a month of maps, messaging, streaming on the train and video calls home for most people, at half the price of not having to think about it.

Buying a Danish SIM on arrival

Copenhagen Airport sells SIMs at WHSmith and 7-Eleven in Terminals 2 and 3, there are vending machines, and carrier stores are easy to find in city centres. A tourist data package at the airport runs about $13 in our data.

A passport is required for registration, so this is a form at a counter rather than a grab-and-go purchase. And $13 buys a lot less confidence than it looks: we do not hold the data allowance on those packs, so we cannot tell you whether $13 beats an $11 five-gigabyte eSIM or loses to it. Ask before you pay.

Networks, and what nobody publishes

Telia Denmark leads on 5G speed and availability, and TDC has the longest-established rural coverage in the country. Those are facts about the operators, not about which one a travel eSIM lands on.

On that second question, Denmark is a country where we hold almost nothing. Airalo, Nomad and Saily do not publish a host network for their Danish plans; Airalo's are sold under the name Teledansk, which is its own product branding rather than a carrier. Holafly does not publish one either: the Danish operators once shown against its rows came from our own data rather than from Holafly, whose country pages name no carrier. An earlier version of this page also presented Airalo's Danish plans as a 3 Denmark service, which nothing in our data supports and which has been removed.

Coverage gaps are minimal for visitors. The Faroe Islands and Greenland run separate networks and are not covered by a Denmark plan. Bornholm is well served, though some remote beach stretches are weaker. Emergency calls work on any Danish network without an active plan.
