Denmark is Copenhagen's harbour, Tivoli and the bicycle lanes, Billund for Legoland, and the castles and coast of Zealand and Jutland within a couple of hours' drive. Data matters for the DOT transit app, for the bike-share and for a country that has all but given up on cash. Danish SIMs are sold at 7-Eleven, but an eSIM is working on the metro from Kastrup airport.

Holafly sells only unlimited plans for Denmark, so it has no price in the GB rows; its 7-day plan is in the week table below.
A week of unlimited data in Denmark
| Provider | 7 days | What you get |
|---|---|---|
| ONE eSIM | $10.43 | 1 GB a day at full speed, then 512 Kbps until the next day (7 × $1.49) |
| Airalo | $26.50 | 3 GB a day at full speed, then 1 Mbps (fair use) |
| Holafly | $27.50 | No daily cap; fair use may slow very heavy use |
| Saily | $26.99 | 5 GB a day at full speed, then up to 1 Mbps |
| Nomad | $25.00 | 2 GB a day at full speed, then 1 Mbps |
For a week, ONE eSIM's 1 GB a day plan is the cheapest way to stay online all day at $10.43. The cheapest of the others is Nomad at $25.00, which gives more full-speed data a day; compare by how much you use a day, not by the word unlimited.
Which networks power Denmark eSIMs
In Denmark, ONE eSIM plans run on 3 and TDC, both listed with 5G. Every plan names its network and generation before you pay, so you can pick the operator you want. Coverage follows each carrier's own build, so expect the strongest signal in the cities and along the main roads and rail lines, and check the plan's network if you are heading somewhere remote.
Which eSIM should you choose for Denmark?
- Short trip, light use (up to 3 GB): ONE eSIM's 3 GB plan at $4.13 (15 days), the cheapest at that size.
- Two weeks or more (5 to 10 GB): ONE eSIM's 10 GB plan at $11.77 (30 days), the cheapest at that size.
- Heavy use (20 GB): Nomad at $20.00 (30 days) is the cheapest at 20 GB.
- Streaming or video calls every day: compare the unlimited plans above by how much full-speed data each gives a day.
Getting your Denmark eSIM set up
- Confirm your phone supports eSIM and is carrier-unlocked before you buy.
- Install the eSIM over home or airport Wi-Fi before you fly; the QR code or install link needs a working connection to download.
- Land in Copenhagen or Billund, switch on the eSIM line and enable data roaming, then check for a signal from 3 and TDC before you head for the taxi rank or the train.
Denmark eSIM FAQ
- Does a Denmark eSIM work across the bridge in Malmö? Only if the plan lists Sweden. The Øresund bridge is a border; a Nordic or Europe plan covers Copenhagen and Malmö on one eSIM.
- Will the eSIM work in Legoland and on the Jutland coast? Yes. Billund, Aarhus and the west coast are well covered on both Danish networks; only the smallest islands thin out.
- Can I keep my home number active alongside a Denmark eSIM? Yes. Most modern phones run two lines, so your home number stays available for calls and texts while the eSIM carries the data.
- Which networks does a Denmark eSIM connect to? ONE eSIM's plans use 3 5G, TDC 5G; the other providers in this comparison may use different local partners.
- How much data do I need for a week in Denmark? For maps, messaging and photos, 3 GB is enough for most people; add a bigger plan or the daily unlimited option if you stream or work on video calls.
How we check prices
We read each provider's public Denmark page on 27 October 2026 and took its cheapest plan at or above each size, in US dollars before any coupon, with the validity in brackets; ONE eSIM prices are our live list prices on the same day. Prices move, so we re-check every month and keep the date on the page and in the short answer. If a number is out of date, write to support@oneesim.app and we will correct it.
