For most tourists visiting Copenhagen for three to five days, 5 GB or 10 GB is a comfortable choice. For a week or more across Copenhagen, Aarhus, Odense, Skagen, or the Danish islands, 10 GB to 20 GB gives more breathing room.
Roafly supports easy installation methods including Direct Install, QR Code, and Manual setup. That means you can choose the method that fits your phone and travel timing. iPhone users can usually install very quickly with Direct Install, while QR Code setup is practical if you are installing from a laptop or another device.
For travelers comparing Denmark connectivity options before a trip, the Best eSIM for Denmark guide is a helpful next read because it focuses specifically on eSIM selection, coverage, and travel use cases.
Denmark Mobile Coverage: What to Expect
Denmark has strong mobile coverage in cities, towns, transport corridors, and most populated areas. Copenhagen, Aarhus, Aalborg, Odense, Esbjerg, Roskilde, and major rail routes generally have reliable 4G and 5G access. Coverage can be more variable in rural coastal areas, ferry routes, forests, and smaller islands, but Denmark is still one of the easier countries for mobile connectivity.
OpenSignal’s Denmark mobile network report from February 2026 found that TDC led Denmark for overall coverage experience, with a score of 9.3 out of 10, and also retained the 5G coverage experience award. The same report placed 3 lower for geographic coverage, while still active as one of Denmark’s major mobile networks.
This matters for travelers because network quality is not only about speed. Coverage is especially important when you are using maps outside Copenhagen, taking trains between cities, cycling along the coast, driving to Møns Klint, or visiting smaller towns.
In practical terms:
- Copenhagen and major cities are easy for mobile data.
- Train routes and highways are usually well covered.
- Rural beaches, ferries, and islands may have weaker signal.
- Indoor signal can vary in older buildings, basements, museums, and metro stations.
A phone that supports modern European 4G and 5G bands will usually perform well. If you are using an older phone from outside Europe, check that it supports common LTE bands used in the region before relying on it as your only connection.
How Much Mobile Data Do You Need in Denmark?
Denmark is a digital-first travel destination. You may need mobile data for public transport tickets, train schedules, restaurant reservations, hotel check-in, navigation, translation, banking verification, and messaging. Even if you plan to use hotel WiFi, mobile data is useful every time you step outside.
A light user can manage with 1–3 GB for a short trip. This means messaging, email, maps, and basic web searches. A regular tourist should choose 5–10 GB for a city break because maps, photos, social media, and travel apps use more data than expected. Heavy users should consider 20 GB or more, especially when using hotspot, video calls, cloud backups, or remote work tools.

Try to avoid automatic cloud photo backups on mobile data unless you have a large plan. Streaming video on mobile data can also drain your allowance quickly. Download offline maps, podcasts, and playlists on WiFi before leaving your hotel.
Pocket WiFi in Denmark
Pocket WiFi is a portable router that creates a private WiFi network using mobile data. It can be useful for families, small groups, business teams, or travelers carrying several devices. Instead of buying separate SIMs or eSIMs for every phone, you connect phones, tablets, and laptops to one portable hotspot.
Pocket WiFi rental for Denmark is available from international rental companies. Hippocketwifi lists Denmark pocket WiFi rental from €3.95 per day, with flexible delivery options. Other providers advertise devices that can connect up to 10 devices at once, which can be useful for groups.
The downside is convenience. You need to order the device, receive it, charge it, carry it, and return it. If the battery dies, every connected device loses internet. For solo travelers and couples, an eSIM is usually lighter and simpler. For families with children using tablets, pocket WiFi can still make sense.
Pocket WiFi Pros and Cons
| Pros |
Cons |
| Connects several devices at once |
Extra device to carry |
| Useful for families and business groups |
Needs charging |
| Can work for laptops and tablets |
Delivery or return may be required |
| Private connection compared with public WiFi |
Often more expensive than one eSIM |
| Good for shared travel data |
Not ideal if group members split up |
Pocket WiFi is best when everyone travels together. If your group separates during the day, each person may still need their own mobile data.
Airport WiFi and Public WiFi in Denmark
Free WiFi is widely available in Denmark at airports, hotels, cafés, coworking spaces, museums, libraries, and some public buildings. Copenhagen Airport’s official WiFi is free and available across the terminal, including before and after security.
Public WiFi is useful, but it should not be your main internet plan. It is not always available when you need directions, when you are outside, or when you need to receive a verification code. Speeds can vary, and some networks require email registration, social login, or a local phone number.
Security is another reason to be careful. Public WiFi is shared by many users. Avoid logging into sensitive accounts, banking apps, or work systems on open networks unless you use a trusted VPN. For transport, maps, and messaging, mobile data is usually safer and more reliable.
Use public WiFi as a backup for:
- Downloading large files at your hotel
- Updating apps
- Streaming at your accommodation
- Checking flight details at the airport
- Saving mobile data when sitting in cafés
Do not rely on public WiFi for:
- Walking navigation
- Ride-hailing pickup points
- Train platform changes
- Digital tickets
- Banking verification
- Emergency communication
Best Internet Option for Different Denmark Trips
The best way to get internet in Denmark depends on your route and travel style.
Weekend in Copenhagen
For a weekend in Copenhagen, a Roafly eSIM is usually the easiest choice. You can install it before leaving home and use it immediately for metro directions, hotel check-in, restaurant searches, and Nyhavn or Tivoli navigation. A 3 GB or 5 GB plan is usually enough for light to normal use.
One Week in Denmark
For a one-week trip including Copenhagen, Aarhus, Odense, or day trips to castles and coastal towns, choose 5 GB to 10 GB. This gives enough data for maps, photos, messaging, and daily travel planning without worrying about every megabyte.
Long Stay or Remote Work
For longer stays, a local SIM can be very cheap if you want a Danish number and do not mind local setup. However, a larger Roafly eSIM plan is easier if you mainly need data and want to avoid store visits. The 20 GB or 50 GB options are better for hotspot use and remote work.
Family Trip
For families, there are two good options. Each traveler can use an individual eSIM, or the group can rent pocket WiFi. If everyone stays together, pocket WiFi can work well. If people split up, individual eSIMs are more reliable.
Denmark Plus Other European Countries
If your trip continues beyond Denmark, check your plan’s coverage before buying. Local Danish prepaid SIMs may include limited EU roaming, but the allowance can be smaller than the domestic data allowance. For example, some low-cost local plans include only a few GB for EU roaming even if the Denmark data allowance is higher.
If Switzerland is part of your wider route, it is worth checking whether your Europe plan includes it, because Switzerland is not always treated the same as EU destinations. The guide on whether an EU SIM works in Switzerland explains this issue in more detail.
eSIM vs Local SIM in Denmark
Both eSIMs and local SIM cards work well in Denmark. The decision comes down to convenience, price, and whether you need a phone number.
A local SIM is attractive because entry-level packages can be extremely cheap. If you are staying for a month, need domestic calls, or want a Danish number, local prepaid plans are worth considering. The main inconvenience is the buying and activation process. You need to find a store, check the package details, and make sure the SIM works with your device.
An eSIM is better for travelers who value speed and simplicity. You can install it in advance, keep your original SIM active for calls or SMS, and start using data as soon as you land. There is no plastic SIM, no store visit, and no risk of losing your home SIM.

Step-by-Step: How to Get Online Before You Land
The smoothest approach is to prepare your mobile internet before your flight.
First, check that your phone supports eSIM. Most recent iPhones, Google Pixel devices, Samsung Galaxy S and Z models, and many newer Android phones support eSIM, but compatibility depends on the exact model and region.
Second, choose a Denmark eSIM plan based on your trip length. Light users can choose 1–3 GB. Most tourists should choose 5–10 GB. Heavy users or remote workers should choose 20 GB or more.
Third, install the eSIM before departure using iOS Direct Install, QR Code, or Manual setup. Keep your primary SIM active if you need to receive SMS from your bank, airline, or messaging apps.
Fourth, turn on the eSIM line after landing in Denmark. Enable data roaming for the eSIM if required by your phone settings. Make sure mobile data is assigned to the eSIM, not your home SIM, to avoid roaming charges.
Finally, test your connection before leaving the airport. Open maps, send a message, and check your hotel route while you are still inside the terminal.
Final Recommendation
For most travelers visiting Denmark in 2026, the best internet option is a Denmark eSIM because it removes the main pain points of airport SIM cards and local prepaid SIM setup. Airport SIM cards are useful if you need a physical SIM immediately. Local prepaid SIMs are cheap for longer stays. Pocket WiFi works well for groups. Public WiFi is helpful as a backup.
But for a normal trip to Copenhagen, Aarhus, Odense, Aalborg, or a multi-city Denmark itinerary, an eSIM gives the best balance of convenience, price, and reliable access.
Check the latest Denmark eSIM packages before your trip and arrive ready to connect.
