デンマーク向けSimbye eSIMの使い方
2分以内に接続できます
Buy before you leave
You get the eSIM by email: a link to tap and a QR code to scan. Set it up calmly at home on Wi-Fi – you do not need a Danish network for that yet. Validity does not start at purchase, so you can order weeks ahead.
Arrive in Denmark
Whether you land at Copenhagen Kastrup, Billund, Aarhus, Aalborg or Rønne on Bornholm, cross the border at Padborg, or come in on the ferry from Puttgarden to Rødby: switch data roaming on after you arrive. Your phone finds the Danish network by itself, usually within a minute or two.
Get going
Validity starts with the first connection to a Danish network. Hotspot is allowed, so you can share with a tablet, a laptop or your travel companions' phones. Running low? Top up online – the eSIM stays in your phone.

デンマークではどれくらいのデータ量が必要ですか？
当てずっぽうではなく、ちゃんと計算できるように。旅行で実際に使うアプリが、1時間あたりどれくらいデータを使うのかをまとめました。
Netflix と Spotify の数値は各社の公式情報（Netflix ヘルプセンター、Spotify サポート、2026年8月28日取得）。それ以外は通信事業者（o2、Vodafone、EE）の目安で、画質や電波状況によって変わります。
デンマークではどの通信ネットワークにつながりますか？
Your phone picks between TDC, Telenor and Telia on its own – there is nothing to set up.

The eSIM is not tied to one operator. After you land, your phone connects automatically to an available Danish network: TDC, run by nuuday, has its own, and Telenor and Telia have shared one for years. For you that simply means there is a fallback – if the signal drops, your phone looks for the next available network on its own. You never pick a carrier and you never type in settings. The only thing that matters is leaving data roaming switched on: the eSIM is a guest on a Danish network, and that is exactly what the switch is for.
In Copenhagen, Aarhus, Odense, Aalborg, Esbjerg, Roskilde and Helsingør you have coverage essentially everywhere, almost continuous 4G in the cities and 5G across large parts of them. The holiday regions are well served too: the North Sea coast around Blåvand, Henne Strand, Søndervig and Hvide Sande, the Ringkøbing Fjord, Rømø and Fanø, Djursland and the Legoland area near Billund, Skagen at the northern tip, Møns Klint, Marielyst on Falster, the Limfjord and the island of Bornholm. It gets thin in some dune hollows and woodland on the west coast, on very small islands and out at sea: on the ferries across the Kattegat or over to Bornholm the connection can drop out for long stretches. Holiday houses often have slow Wi-Fi or none at all – there the mobile network is usually the faster line.
デンマークではeSIMと現地のSIMカード、どちらがよいですか？
| 比較 | Simbye eSIM | 現地SIMカード |
|---|---|---|
| Ready before departure | Buy online, scan the QR code at home on Wi-Fi – validity only starts in Denmark | Only after you land – you hunt for a counter at the airport or a 7-Eleven |
| ID or registration | Not required | Some Danish providers now ask you to register via MitID – residents only |
| Price and currency | Fixed price, paid before you leave | Danish kroner at the till, plus exchange rate and possible card fees |
| At the airport | Nothing to sort out – switch data roaming on and you usually have signal within a minute or two | Copenhagen Kastrup has kiosks; Billund, Aarhus and Aalborg offer far less choice |
| Time it takes | A few minutes, once | Getting there, queueing, activating – easily an hour of your first holiday day |
| Phone number | None, this is a data-only plan | A Danish number is usually included, but often tied to registration |
| Topping up | Online any time, the same eSIM stays in your phone | Buy a voucher code, menus often in Danish only |
| Second line | Runs alongside your usual number, so home can still reach you | You swap the card out or carry a second phone |
Why travellers bring their own data eSIM to Denmark
Roaming on your home contract is the expensive and unpredictable part of a trip: many plans bill Denmark by the day or by the megabyte, and the ones that do include roaming almost always cap how much data you may use abroad. In a holiday house with unusable Wi-Fi that cap arrives faster than you would expect, and once it is gone you are either throttled or paying extra after the fact. A prepaid eSIM turns all of that into one decision you make before you leave: no contract, no registration, nothing to cancel afterwards.
Copenhagen is a major cruise and conference port, and many people arriving here have flown a long way. For them, a few days of maps and navigation on a home plan is often the bigger item on the bill. The third case is the second line: people travelling on business prefer to keep data use and billing cleanly apart from their private number, and the eSIM simply runs alongside the SIM already in the phone.
On top of that, Denmark is an unusually digital country. Parking runs through an app, train tickets run through an app, a rental bike will not unlock without a connection, and even small shops expect a card rather than cash. Being offline in Denmark leaves you more stranded than in most countries – which is exactly why a second, independent data connection is worth more here than elsewhere.
How far the Danish networks actually reach
Two radio networks matter for your eSIM in Denmark: TDC runs its own, and Telenor and Telia merged theirs into a shared network. In practice that means a fallback whenever one of them is weak in a given spot. In the cities coverage does not stop underground either – you usually have signal on the Copenhagen metro, and the regional trains across Zealand and Funen work too, with the usual short gaps in cuttings and tunnels.
It gets weaker where almost nobody lives: deep dune hollows and pine woods right on the west coast, small islands such as Læsø, Samsø or Ærø depending on where you stand, and out at sea. On the ferries – across the Kattegat, over to Bornholm or towards Germany – the connection can disappear entirely for long stretches mid-crossing. That is not specific to this eSIM; it applies to every phone on board. Exactly where the edge lies depends on the individual spot, and nobody can promise you coverage at every point along the coast. So plan the ferry as a dead zone: download your maps and tickets beforehand and the crossing is a non-issue.
Denmark stops at the border – Greenland and the Faroe Islands are not included
The plan covers the Danish part of the kingdom: Jutland, Funen, Zealand, Bornholm and the smaller islands in between. The Faroe Islands and Greenland belong to Denmark constitutionally, but they have their own operators, their own country codes and are billed separately – this eSIM does not work there. It only gets expensive if your usual SIM connects there instead. Coverage likewise ends on the Øresund Bridge towards Malmö, on the ferry to Puttgarden, and on the fast Bornholm route via Ystad in Sweden. On Bornholm itself you are back in Denmark.
You do not have to register in Denmark: there is still no legal ID or registration requirement for prepaid SIMs, and proposals to introduce one have not passed. Working the other way, some Danish providers have voluntarily made life harder for visitors by requiring MitID – the Danish digital ID, available to residents only – for new prepaid cards. With an eSIM that is already installed before you leave, the question never comes up.

デンマークで本当に必要なアプリ
Denmark runs on the phone: parking, transport tickets, rental bikes, museum and ferry entries, payments. Arrive without data and you will literally be standing in front of things you cannot open. Cards, Apple Pay and Google Pay work virtually everywhere, and you will rarely need cash – but MobilePay, the app Danes actually use between themselves, stays closed to visitors. For food, Wolt is the big delivery service in the country. Outside the larger cities – in the west-coast holiday-house areas, for example – nobody delivers at all. For parking, EasyPark gets you furthest, and Too Good To Go, founded in Copenhagen, is unusually well stocked in Denmark. One thing applies to every sign-up: many services send the confirmation code by SMS. This eSIM has no number and receives no texts – use your usual number for that, the one that stays in your phone.
Rejseplanen
The journey planner for all of Denmark: bus, train, metro and ferry in one search, with live departures, platforms and transfer times. No account needed, available in English.
Rejseplanen only shows connections. You buy the actual ticket in a different app or at a machine.
Rejsebillet
The ticket app for public transport across Denmark. Buy single tickets and passes on your phone and show them when the inspector comes.
As a traveller, use this one. The similar-sounding Rejsekort app asks for MitID and a Danish CPR number – residents only. As a traveller, do not count on the physical Rejsekort card any more.
MobilePay
Denmark's payment app. Danes use it to send each other money and to pay at flea markets, farm shops, clubs and small kiosks.
Not usable for tourists: MobilePay requires a Danish bank account, a Danish phone number, a CPR number and MitID. Use your card, Apple Pay or Google Pay – accepted almost everywhere in Denmark, and you will barely need cash.
Dantaxi
Taxi app with drivers across a large part of the country, including smaller towns and regions where nothing else runs.
In holiday-house areas there is often no app-based ride at all – you book through the local taxi company's website, or by phone using your usual number. This eSIM cannot make calls.
Donkey Republic
Rental bikes in Copenhagen, Aarhus, Odense and Aalborg. Unlock by QR code, pay in the app, park again at an allowed spot.
Without mobile data you cannot start or end the rental – cycling in Denmark runs through the app. Foreign cards, Apple Pay and Google Pay are accepted.
DMI
The weather app of the Danish meteorological service, with rain radar and official warnings for storms, heavy rain and coastal flooding.
The app is mostly in Danish. For the North Sea and Baltic coasts it is still the most reliable source – warnings appear there first.
