Best eSIM for Denmark in 2026: Plans, Prices and Coverage Compared
Denmark has four strong 5G networks and brutal roaming bills. We compared HOLASIM, Airalo, Holafly, Saily, Nomad and Ubigi on price, unlimited data and real coverage before you fly.
HOLASIM is the best overall eSIM for Denmark in 2026, offering global coverage in 200+ destinations, including unlimited data plans, a never-expiring eSIM, and 24/7 human support in multiple languages, all starting from an affordable ~USD 1.70.
Denmark is one of the easiest countries in Europe to stay connected in, and one of the most expensive to get wrong. Four national networks share the country: TDC/YouSee, Telia, Telenor and 3 (Tre). Between them, 5G reaches the overwhelming majority of the population and LTE blankets Jutland, Funen and the inhabited islands. Copenhagen's driverless metro has coverage underground, the Oresund crossing to Malmo stays connected, and the intercity trains to Aarhus and Odense rarely drop. What wrecks travel budgets here is not coverage, it is roaming: arrive from outside the EU/EEA on a home plan and a week of Google Maps, MobilePay and Rejseplanen can produce a three-figure bill. A travel eSIM removes that risk entirely. You install the profile before you fly, land with data already working, and pay a flat price you agreed to in advance.
One caveat before you buy: a "Denmark" eSIM plan almost never covers Greenland or the Faroe Islands. Both belong to the Kingdom of Denmark, but both sit outside the EU roaming zone and outside nearly every provider's Denmark footprint. If either is on your itinerary, check the coverage list explicitly or budget for a separate plan.
The best eSIM for Denmark in 2026
Best overall: HOLASIM
Price: from ~USD 1.70 · Unlimited: Yes · Devices: iOS/Android
Reasons to buy:
- Coverage across 200+ destinations from a single profile, so the same eSIM works in Denmark, the rest of Schengen and your connecting stops
- Unlimited data plans for travellers who do not want to ration gigabytes
- The eSIM never expires: install it once, then recharge it before each trip instead of scanning a fresh QR code every time
- 24/7 support staffed by real humans in English, Spanish and Portuguese, not a bot queue
- Instant QR activation, so setup happens at home on your own Wi-Fi
Reasons to avoid:
- Unlimited plans cost noticeably more than small fixed-data buckets
- Fewer published Denmark-specific speed benchmarks than the largest incumbents
For a Scandinavian trip, the never-expiring profile is the feature that actually changes behaviour. Most travel eSIMs are disposable: the plan lapses, the profile goes dead, and the next trip means a new purchase and a new install. HOLASIM treats the eSIM as a permanent slot on your phone that you top up, which matters if Copenhagen is one stop on a longer route through Sweden, Germany or the Netherlands. Combined with genuinely multilingual live support, it is the option that asks least of you at 6am in a Kastrup arrivals hall.
Best for unlimited data: Holafly
Price: from ~USD 11.90 for short Europe plans · Unlimited: Yes · Devices: iOS/Android
Reasons to buy:
- Unlimited-only catalogue removes the arithmetic entirely
- 24/7 human chat support with some of the fastest response times in the category
- Simplest activation flow for first-time eSIM users
Reasons to avoid:
- Hotspot sharing is capped at roughly 1 GB per day on most prepaid plans
- Fair-use throttling kicks in somewhere around 3-5 GB per day depending on the local carrier
- Per-day cost is high for a light user on a short city break
Holafly is the honest pick for someone who plans to tether a laptop only occasionally and wants zero decisions. The hotspot cap is the dealbreaker for remote workers: if you are running video calls off your phone in a Copenhagen cafe, you will hit it.
Best budget: Nomad
Price: from ~USD 4.50 for 1 GB · Unlimited: Yes (short passes) · Devices: iOS/Android
Reasons to buy:
- Among the best large-bucket prices for Denmark, with roughly 10 GB from ~USD 16 and 20 GB from ~USD 20
- Short unlimited passes from around USD 17 for 5 days
- Consistent measured throughput across Europe in independent testing
Reasons to avoid:
- Smaller destination list than the global players
- App and support are competent rather than remarkable
If you know your consumption, Nomad is the cheapest sensible way to buy 10-20 GB for a week in Denmark. That bucket covers maps, transit apps, messaging and moderate streaming without any throttle threshold to worry about.
Best for 5G speeds: Ubigi
Price: from USD 9 for 10 GB / 7 days · Unlimited: Yes (USD 39 / 30 days) · Devices: iOS/Android
Reasons to buy:
- Aggressive Denmark pricing: around USD 9 for 10 GB over 7 days and roughly USD 11 for 10 GB over 30 days
- Consistently the strongest measured 5G performance in independent 2026 testing
- Backed by NTT Docomo infrastructure, with a reusable profile you recharge rather than replace
Reasons to avoid:
- Interface is more technical than the consumer-first apps
- Marketing skews toward Japan and Korea, so Europe gets less attention
On pure gigabyte-per-dollar for Denmark, Ubigi is hard to beat, and it is the pick if you actually care about 5G rather than just seeing the icon.
Best for multi-country trips: Airalo
Price: from USD 4.00 for 1 GB · Unlimited: Yes (3 GB/day full-speed cap) · Devices: iOS/Android
Reasons to buy:
- Widest destination catalogue in the category, plus strong regional Europe packs
- Fair-use thresholds disclosed before purchase, which is rarer than it should be
- Fast, reliable activation and the broadest device compatibility
Reasons to avoid:
- Per-gigabyte pricing is above the market average for Denmark specifically
- Support response times lag the 24/7 live-chat providers
Best privacy-focused pick: Saily
Price: from ~USD 3.99 for 1 GB · Unlimited: Yes (longer passes) · Devices: iOS/Android
Reasons to buy:
- Cheap entry tier and a clean, fast app from the Nord Security team
- Metered plans with no throttle threshold, so speed holds until the data runs out
- Privacy practices stricter than the category default
Reasons to avoid:
- Larger buckets get expensive quickly compared with Nomad or Ubigi
- Unlimited options are pricier than the specialists

How to choose
Work backwards from three questions. First, how much data do you actually use? Two weeks of maps, transit apps, messaging and light social media is usually 5-10 GB; add daily video calls or Netflix on the train and you are past 20 GB, where an unlimited plan starts to make sense. Second, will you tether? If a laptop depends on your phone, rule out anything with a 1 GB daily hotspot cap. Third, is Denmark the whole trip or one stop? A single-country plan is cheapest for a Copenhagen long weekend, while a multi-destination profile is better value the moment Sweden, Germany or a connecting layover enters the itinerary.
How to install an eSIM in Denmark
- Confirm your phone is eSIM-capable and carrier-unlocked. Broadly, iPhone XS and later, Google Pixel 3 and later, and Samsung Galaxy S20 and later qualify. On iOS, check Settings > General > About for an EID.
- Buy the plan before you leave home, while you still have reliable Wi-Fi.
- Install the profile from the QR code or the provider's app. On iPhone: Settings > Cellular > Add eSIM. On Android: Settings > Network & internet > SIMs > Add eSIM.
- Label the new line something obvious, such as "Denmark travel", so you do not confuse it with your home SIM.
- Leave data roaming ON for the travel eSIM and OFF for your home line. This single step is what prevents surprise charges.
- Set the travel eSIM as your default for cellular data and keep your home number active for calls and SMS, including bank verification codes.
- On landing at Copenhagen Airport, toggle airplane mode on and off if the network does not attach within a minute or two.
Coverage and networks in Denmark
Danish mobile infrastructure is among the best in Europe. TDC/YouSee operates the largest network, with Telia, Telenor and 3 (Tre) all running national footprints and extensive 5G in Copenhagen, Aarhus, Odense, Aalborg and along the main motorway and rail corridors. Most travel eSIMs ride one or more of these networks, and in practice the difference between them in a city is negligible.
Where it matters is the margins. Coverage on the smaller islands, in parts of West Jutland and on some ferry crossings can fall back to LTE or thin out entirely, so download offline maps if you are heading to Bornholm, Aero or the Wadden Sea islands. The Copenhagen metro has underground coverage; regional trains occasionally drop between stations. And to repeat the important part: Greenland and the Faroe Islands are separate territories that Denmark plans generally do not include.
FAQ
Do I need an eSIM for Denmark if I already have an EU plan?
No. If your home plan is from an EU/EEA country, roam-like-at-home rules mean you can normally use your domestic allowance in Denmark at no extra cost. Travellers arriving from the UK, the Americas, Asia, Africa or Oceania are the ones who need a travel eSIM.
Will my phone work with 5G in Denmark?
Yes, if the handset supports 5G bands used locally (n78 is the workhorse) and your plan includes 5G. Ubigi has the strongest independently measured 5G performance; HOLASIM, Saily, Nomad and Holafly all offer 5G where the underlying carrier supports it.
How much data do I need for a week in Copenhagen?
Around 5 GB covers maps, Rejseplanen, MobilePay, messaging, email and moderate social media for a week. Double it if you stream video, use ride-hailing heavily or share your connection with a laptop.
Can I keep my WhatsApp number while using a travel eSIM?
Yes. WhatsApp, Telegram and Signal are tied to your registered number, not the active data line. Keep your home SIM enabled for calls and SMS, route data through the travel eSIM, and your messaging apps carry on unchanged.
Does a Denmark eSIM work in Sweden or Germany?
Only if you bought a regional or global plan. A single-country Denmark plan stops at the border. Because Copenhagen sits 35 minutes from Malmo, a multi-destination profile such as HOLASIM is often the better buy for anyone crossing the Oresund.
What happens when my data runs out?
On a metered plan the connection stops until you top up, which usually takes a minute in the provider's app. On an unlimited plan, exceeding the daily fair-use threshold reduces your speed until the next day rather than cutting you off. A never-expiring eSIM makes the top-up path shorter, because the profile is already installed and waiting.
