The best eSIM for Denmark depends on where else you go. If you stay in Denmark, a Denmark data plan sized to your trip is the simplest choice. If you also visit Sweden, Norway or Germany, a Europe eSIM covers them with one plan. And if you need a phone number for calls and texts, pick a Bouygues Telecom plan with a French +33 number. Either way, you install the eSIM at home and it connects when you land. This guide compares the eSIMs for Denmark sold on SimOptions by trip length, data, coverage and phone number, using the current plan details on our Denmark eSIM page.
Short on time? Here are three plans for three typical trips: a week in Denmark, two weeks in Denmark, and two weeks with a phone number and room to cross into other countries.

Every plan is prepaid with no contract. You get your eSIM by email as a QR code. Once installed, it activates automatically when you arrive in a covered country. If you don't use it within a year of buying it, it expires.
Which eSIM is best for your Denmark trip?
Start with how long you stay, then ask yourself two questions: do you cross a border, and do you need a phone number?
City break (up to a week): Denmark 3GB, 5GB or 10GB
For a long weekend in Copenhagen, Aarhus or Odense, a small Denmark plan covers maps, messages, transport apps and browsing. The 3 GB plan lasts 3 days, the 5 GB and 10 GB plans last 7 days. If you run low, you can top up.
Two weeks in Denmark: Denmark 20GB
For a longer holiday, say Copenhagen, a few days in Jutland and a ferry to an island, Denmark 20GB gives you 20 GB for 15 days, and you can top it up.
A month or a long stay: Denmark 50GB, 60GB or 100GB
Studying, working remotely or spending the summer in a holiday house? Denmark 50GB lasts 30 days. Denmark 60GB lasts 90 days and Denmark 100GB lasts 180 days, so you don't need a new eSIM every month. All three can be topped up.
You need a phone number: Travel Basic+ or My European eSIM
The Denmark plans are data only. You can still call and text with WhatsApp, FaceTime or iMessage, see how to make calls with a data-only eSIM. If a hotel, a tour operator or a car rental desk needs to call or text you on a normal number, Travel Basic+ and My European eSIM give you a French +33 number with unlimited calls and SMS within Europe, Danish numbers included. The plan details list calls and SMS within Europe only, so calls to the US, Canada or Australia aren't included. No SimOptions eSIM gives you a Danish +45 number. Our guide to Europe eSIMs with a phone number explains when you really need one.
Visiting Sweden, Norway or Germany too? Pick one Europe eSIM
Many Denmark trips don't stop at the border. You take the train over the Öresund Bridge from Copenhagen to Malmö, drive on to Oslo or head south into Germany. A Denmark plan only works in Denmark. A Europe eSIM keeps you online in all of them, so you don't need a new eSIM in each country. That is also the answer if you're searching for the best eSIM for Denmark and Sweden: the Denmark and Sweden plans each cover one country, so pick a Europe plan for both.
- Europe 20GB (SimOptions): 20 GB for 15 days in 34 countries, including Denmark, Sweden, Norway and Germany. Data only, 4G/LTE, top-ups available. When we checked, the Denmark plan of the same size cost a little less, so pick the Europe plan only if you really cross borders.
- Travel Basic (Bouygues Telecom): 15 GB for 15 days in 46 countries, Iceland included. Data only, 5G.
- Travel Basic+ (Bouygues Telecom): 20 GB for 15 days in the same 46 countries, with a French +33 number.
Going to Iceland as well? Pick a Bouygues Telecom plan, since the SimOptions Europe plans don't cover it. Neither covers the Faroe Islands or Greenland, so check our destinations page if they are on your route.

Local SIM cards and eSIMs in Denmark
YouSee, Telenor, Norlys (formerly Telia) and 3 all offer eSIM, but mostly on subscriptions you manage in their own apps. YouSee, for example, ships its eSIM through Mit YouSee, where you log in with MitID, Denmark's digital ID (YouSee: Order and activate eSIM). Our guide to eSIM providers in Denmark shows what each carrier offers visitors.
A local line makes sense if you move to Denmark or need a +45 number. For a holiday or a business trip, a travel eSIM you install before you leave is quicker: no account, no app and no shop visit after you land.
How much data do you need in Denmark?
You'll use data for more than maps. In Copenhagen and the rest of Zealand, you can buy public transport tickets in the DOT Tickets app (Din Offentlige Transport: the app). The app asks you to verify your phone number with an SMS code, so keep your home line switched on for texts. Wi-Fi at your hotel helps, but plan for data on the go. As a rough guide:
- 3 to 5 days: 1 GB to 5 GB for maps, messages and some browsing.
- 7 to 15 days: 10 GB to 20 GB, enough for social media, photos and some video calls.
- 15 to 30 days: 20 GB to 50 GB, or more if you stream or work online.
Planning to share your connection with a laptop on the train? Our Denmark eSIM page says hotspot sharing is allowed. Hotspot uses data fast, so go a size up.
Do you need a travel eSIM for Denmark?
Your phone plan is from the EU: check it first
Denmark is in the EU, so under the "roam like at home" rules you can use a plan from another EU country at domestic prices, within your carrier's fair use limits. The rules also cover Iceland, Liechtenstein and Norway, plus Moldova and Ukraine (Your Europe: Mobile roaming costs). A travel eSIM still helps if your plan has a small data allowance abroad.
You're coming from the UK, the US, Australia or Canada
Roam like at home doesn't apply to these plans. For UK plans, the UK government says surcharge-free roaming in EU and EEA countries is no longer guaranteed, so check your provider's charges for Denmark (GOV.UK: Using your mobile in EU and EEA countries). Other carriers set their own roaming prices. A travel eSIM gives you local data at a fixed prepaid price, while your home SIM stays on your phone for texts and security codes.
Is your phone compatible?
Your phone must support eSIM and be unlocked. On iPhone, eSIM works on the iPhone XS, XS Max, XR and later (Apple: Using Dual SIM with an eSIM). For Android phones, see our guide to checking eSIM compatibility. If you bought your phone from a carrier, ask it to unlock the phone before you travel.
How to set up your eSIM for Denmark
- Buy your plan and get your QR code by email.
- Install it at home on Wi-Fi before you fly. Step-by-step help: how to install an eSIM and Apple's guide to setting up eSIM on iPhone.
- Label the line "Denmark" or "Travel" so you can tell it apart from your home line.
- When you arrive, the eSIM connects automatically. Choose it as your line for mobile data and turn on data roaming for it. On iPhone, go to Settings > Cellular (or Mobile Data) > Cellular Data and pick the travel eSIM (Apple: Using Dual SIM with an eSIM). On a Pixel, use Settings > Network & internet > SIMs (Google: Use dual SIMs on Pixel).
- Turn off data roaming on your home line, so it can't use data abroad.
No signal after you arrive? Our guide on what to do when your eSIM is not activating walks you through the fixes, and the correct roaming settings guide covers the roaming switches.
FAQs
What is the best eSIM for Denmark?
It depends on your trip. For a week in Denmark, Denmark 5GB or 10GB. For two weeks, Denmark 20GB. For a long stay, Denmark 60GB or 100GB. If you also visit Sweden, Norway or Germany, Europe 20GB or Travel Basic. If you need a phone number, Travel Basic+ or My European eSIM from Bouygues Telecom.
What is the best eSIM for Denmark and Sweden?
A Europe eSIM, since a Denmark plan doesn't work in Sweden. Europe 20GB covers both for 15 days, data only. Travel Basic and Travel Basic+ cover both too, and Travel Basic+ adds a French +33 number.
Does my eSIM work in Copenhagen?
Yes. A Denmark plan covers the whole country, Copenhagen included, and so do the Europe and Bouygues Telecom plans. If you take the train across the Öresund Bridge to Malmö, you need a Europe plan to stay online in Sweden.
Can I get an eSIM for Denmark with calls?
Yes. Travel Basic+ and My European eSIM come with a French +33 number and unlimited calls and SMS within Europe, including calls to Danish numbers. The Denmark plans are data only.
Can I get a Danish phone number with a travel eSIM?
Not with the SimOptions plans. For a +45 number, you need a line from a Danish carrier or prepaid brand.
What is the cheapest eSIM for Denmark?
The smallest plan, Denmark 1GB for 3 days, is the cheapest one on our Denmark eSIM page. For a longer trip, pick the plan that matches your days and data, so you don't pay for more than you use.
Can I top up my Denmark eSIM?
The Denmark and SimOptions Europe data plans can be topped up. The Bouygues Telecom plans can't, so choose enough data and days before you go.
Can I keep my own number and WhatsApp?
Yes. On a dual SIM phone, your home line stays on next to the travel eSIM. WhatsApp keeps your usual number and works over the eSIM's data.
Does the Denmark eSIM work in the Faroe Islands or Greenland?
No. The Denmark plans cover Denmark only, and neither the Europe nor the Bouygues Telecom plans list the Faroe Islands or Greenland. Check our destinations page for a plan that does.
