Quick verdict: which Denmark eSIM to buy
Denmark has near-universal 4G coverage across a compact, densely populated country, so almost any fixed-data Flysimio plan will comfortably cover a typical trip. The gap against unlimited pricing is large enough that unlimited rarely makes sense here.
| Trip length | Recommended plan | Approximate cost |
|---|---|---|
| Long weekend in Copenhagen | Flysimio 3 GB / 30 days | $4.98 |
| 1–2 weeks (Copenhagen + islands) | Flysimio 5 GB / 30 days | $8.50 |
| 2–3 weeks, remote work or heavy use | Flysimio 10 GB / 30 days | See live price in the index above |
| Extended stay | Flysimio 20 GB / 30 days | See live price in the index above |

How this table is priced. Flysimio prices are read live from our carrier catalog every time this page loads, so the figure here is the figure at checkout. Competitor prices are the US-dollar price shown on each provider's own site, read on the date in the last column and linked to the page we read it from; promotional prices are marked alongside the list price. Price per GB is the plan price divided by its included data — unlimited passes have no per-GB figure and are ranked by total price instead.

Frequently asked questions
What is the best eSIM for Denmark?
A fixed-data Flysimio plan is the clear choice — Denmark's compact, densely covered network means even a modest 5–10 GB plan comfortably covers a typical trip, at a fraction of Airalo's unlimited pricing.
Does the eSIM work on the Copenhagen Metro?
Yes. All Copenhagen Metro lines (M1–M4) have 4G coverage throughout, including the underwater Cityringen tunnel sections.
Does this eSIM work on the Øresund Bridge to Sweden?
Yes. The Øresund Bridge has 4G from Copenhagen through to Malmö — your device switches automatically from the Danish to the Swedish network mid-crossing.
Does this eSIM cover Bornholm Island?
Yes. Bornholm has solid 4G in Rønne, Allinge, and around the Hammershus fortress.
How much data do I need for a week in Copenhagen?
For typical use — maps, messaging, and photos — 3 GB is comfortable for a long weekend, and 5 GB covers a full week to ten days with room to spare.
Do I need a special adapter for Danish power outlets?
Not if you're coming from elsewhere in Europe — Danish Type K sockets accept standard Type C and F plugs. Travelers from the US or UK need a standard European adapter, not a Denmark-specific one.
