Quick Answer

The best-value eSIM for Denmark is eSIM4, from $2.98 for 1GB. Across the eight providers compared here, 1GB plans run from $2.98 to $4.99, and eSIM4 is the cheapest of any major provider at 1GB, 2GB, 3GB, 5GB and 10GB.

Nomad wins the biggest bucket: its 20GB ($20.00) and its 7 and 10 day unlimited plans undercut eSIM4, and we show those wins honestly in the tables below. For short trips, eSIM4’s 3 and 5 day unlimited plans are the cheapest in the field, from $9.98.

Prices were verified in August.

The cheapest Denmark eSIM depends on how much data you’ll actually burn, because a single “from” price hides more than it reveals. We compared every plan from eight major providers for this market, size by size, and the picture splits cleanly: eSIM4 wins every fixed plan from 1GB to 10GB plus the 3 and 5 day unlimited, while Nomad shades 20GB and the 7 and 10 day unlimited plans.

This page sticks to price alone; for coverage, apps and support rankings, see our full guide to the best eSIM for Denmark, which ranks the same field in depth.

What is a Denmark eSIM?

An eSIM is a digital SIM that lives inside your phone, so there’s no plastic card to fumble with at arrivals. You buy the plan online, scan a QR code to install it, and it connects to a Danish network the moment you touch down, whether that’s Copenhagen Airport or the ferry terminal at Hirtshals.

Your home SIM stays exactly where it is, so your usual number keeps working.

The plans compared here are travel data eSIMs. They exist to get your maps, translation apps and messages working the second you land, without paying your home carrier’s roaming rates or joining the SIM-counter queue at the airport.

Denmark eSIM price comparison: fixed data

eSIM4 holds the cheapest fixed plan at 1GB, 2GB, 3GB, 5GB and 10GB, highlighted green below, though its 10GB wins by just two cents. Nomad takes 20GB, and Airalo owns the 50GB tier that eSIM4 doesn’t sell.

Where a rival wins, their cell is green and eSIM4’s isn’t, because hiding a competitor’s better price helps nobody.

Where a provider sells a size at several validities, we show its lowest price. Rivals also sell intermediate sizes we don’t tabulate: Jetpac has 15GB, 30GB and 40GB plans, and GigSky runs a 100GB plan valid 180 days at $88.39. eSIM4’s fixed range tops out at 20GB, after which it moves to unlimited.

Prices were checked in August against each provider’s own Denmark pages and are re-checked monthly.

Value check: price per GB

A low sticker price can mislead on a “cheapest” search, because a tiny plan often costs the most per gigabyte. Here’s what you actually pay per GB with eSIM4 against the cheapest rival selling a real plan at that size.

20GB$25.98$1.30$1.00 (Nomad)Nomad

Per-GB figures are rounded to the nearest cent, which is why 5GB and 10GB look tied: eSIM4’s actual rate is fractionally lower at both. eSIM4 leads on $/GB at every size from 1 to 10GB and trails Nomad only at 20GB, by thirty cents per GB.

Denmark eSIM price comparison: unlimited data

Unlimited is where eSIM4’s range shows: it’s cheapest for 3 and 5 day trips, cheapest at 15 days, and the only provider offering a 30 day unlimited plan in Denmark at all. Nomad undercuts the middle ground, edging the 7 and 10 day durations by $1.98, and Saily’s lone unlimited plan misses the 15 day mark by $2.01.

Is Nomad’s $16.00 plan actually cheaper?

At 10GB, no. Nomad’s 10GB costs $16.00 against eSIM4’s $15.98, two cents more. Nomad does win 20GB, where its $20.00 undercuts eSIM4’s $25.98 by nearly six dollars, and its unlimited plans edge the 7 and 10 day durations.

Those wins are real, they’re in the tables above, and pretending otherwise would earn nobody’s trust.

But most Denmark trips are short city breaks that never get near 20GB, and at the sizes people actually buy, eSIM4 wins every time: 1GB for $2.98, 3GB for $6.98, 5GB for $9.98, each the lowest price in the field. Its 3 and 5 day unlimited plans are also the cheapest going, and when a trip stretches past two weeks, eSIM4 has the cheapest 15 day unlimited and the only 30 day one.

So the honest answer is to buy for the size you’ll use. At 10GB or less, eSIM4 beats every rival.

At 20GB, Nomad’s $20.00 is $5.98 under eSIM4’s $25.98, and only you know whether that larger-data discount matters for the way you travel.

Which Denmark eSIM is right for your trip?

For most readers the default is eSIM4: entry plans from $2.98, unlimited starting at $9.98 for 3 days, and the longest unlimited durations in the market. The exceptions are specific and easy to spot, so here are the picks by trip type.

Short trip or light data

eSIM4’s 1GB for $2.98 covers a weekend of maps, MobilePay payments and messages with room to spare, and it’s valid for 7 days. Nothing else in the field dips under $3.95.

A typical week

Take eSIM4’s 5GB for $9.98, which sneaks under Airalo’s $10.00 and undercuts everyone else by a wider margin. Lighter users can drop to 3GB for $6.98 and still cover a week of navigation and social scrolling.

Heavy data or a longer stay

Streamers, tetherers and anyone staying past two weeks should look at eSIM4’s 30 day unlimited for $69.98, the only 30 day unlimited sold in Denmark. On trips of seven to ten days, Nomad’s unlimited plans run $1.98 cheaper, so grab those if you’re mid-range on length.

Families and groups

One plan per phone works out cheapest: 5GB at $9.98 each keeps four travellers online for around forty dollars total. Whoever hotspots the group should carry an unlimited plan instead, and eSIM4’s plans support tethering natively.

Strict single-plan budget

The rock-bottom single purchase in this whole comparison is eSIM4’s 1GB at $2.98. If seven days feels tight for the money saved, Roamless stretches a single gigabyte across 30 days for $3.95, though it can’t match eSIM4 on price at any other size up to 10GB.

Every Denmark eSIM provider compared

We compared eight providers: eSIM4 for small-plan value and long unlimited, Nomad for big data, Saily for simple budget plans, Jetpac for long-validity flexibility, GigSky for jumbo sizes, aloSIM for a plain price ladder, Airalo for sheer catalogue depth, and Roamless for 30-day pay-as-you-go. Here’s how they stack up one by one.

eSIM4 wins this comparison where it matters most for real trips: every fixed plan from 1GB through 10GB, the 3 and 5 day unlimited, the cheapest 15 day unlimited and the only 30 day unlimited sold in Denmark. The Was/Now pricing adds a further cut, with savings running up to $57.82 off the standard rate on the 30 day unlimited.

Pricing. Entry is $2.98 for 1GB, and the ladder climbs gently: $4.98 for 2GB, $6.98 for 3GB, $9.98 for 5GB and $15.98 for 10GB, each the cheapest of any provider here, though the 10GB beats Nomad’s $16.00 by only two cents. The one fixed loss is at the top: $25.98 for 20GB against Nomad’s $20.00 and Roamless’s $24.95.

Saily keeps things deliberately simple: a short plan ladder, clear prices and an app that stays out of the way. For travellers who find eighteen-plan catalogues overwhelming, that restraint is the appeal.

Pricing. The 1GB at $3.99 undercuts most of the field but not eSIM4’s $2.98, and that pattern repeats down the ladder: $7.99 for 3GB, $10.99 for 5GB, $17.99 for 10GB and $27.99 for 20GB, each a shade above eSIM4’s equivalent. The single unlimited plan covers 15 days for $48.99, missing eSIM4’s matching plan by $2.01.

Networks. Connections run on established Danish infrastructure with nationwide 4G and 5G in the cities.

Customer support. Help arrives through in-app chat and email rather than a phone line.

Nomad is the provider to beat once data appetites grow. It owns the 20GB tier outright, sits just two cents above eSIM4 at 10GB, and fields the deepest unlimited bench for mid-length trips, which makes it the natural alternative pick for heavy users staying under two weeks.

Pricing. The headline win is $20.00 for 20GB, comfortably clear of the field, while $16.00 for 10GB sits two cents above eSIM4. Unlimited runs $11.00 for 3 days, $17.00 for 5, $23.00 for 7 and $31.00 for 10, shading eSIM4 at 7 and 10 days.

The entry tier tells the other story: $4.50 for 1GB is the second-dearest starter plan here, behind GigSky’s $4.99, and its 3GB at $9.00 trails eSIM4 by two dollars.

Networks. Plans connect through Denmark’s national carriers with solid 4G and growing 5G footprints.

Jetpac skips small plans entirely and builds its ladder around generous fixed sizes with long validity, aimed at travellers whose dates shift and who’d rather install one plan and forget about it.

Pricing. There’s no 1GB or 2GB starter, so entry begins at $12.00 for 3GB, about 1.7 times eSIM4’s price at the same size. The interesting rung is 15GB for $24.99, slotting between everyone else’s 10GB and 20GB, and 40GB for $34.99 undercuts most rivals’ 20GB rates per gigabyte.

Its 20GB at $40.00, though, is the dearest plan of that size in this field.

GigSky plays a different game: fewer everyday plans, but sizes and validities nobody else touches, including a 100GB plan that stays live for half a year. Long-project travellers and remote workers are the target.

Pricing. Everyday sizes run hot: $4.99 for 1GB, $9.34 for 3GB and $14.02 for 5GB all cost more than eSIM4’s equivalents. The case only exists at the top, where 90-day validity on the $58.62 50GB (Airalo’s and Nomad’s 50GB plans run 30 days) and 100GB for $88.39 over 180 days have no competition in this field.

aloSIM runs one of the tidiest catalogues here: six plans stepping evenly from 1GB to 20GB, no odd sizes, no gimmicks. It’s easy to compare and easy to buy, which counts for plenty on a busy travel day.

Pricing. Each rung sits just above eSIM4: $4.00 versus $2.98 at 1GB, $8.00 versus $6.98 at 3GB, $11.00 versus $9.98 at 5GB. The gap widens at the top, where its $30.00 for 20GB trails both eSIM4 ($25.98) and Nomad ($20.00).

Airalo’s strength is breadth: twelve Denmark plans spanning three validity lengths, including the only 50GB plan in this comparison. Travellers who like choices will always find something here, even if the sharpest prices live elsewhere.

Pricing. Matched sizes mostly trail eSIM4: $4.00 versus $2.98 at 1GB and $8.00 versus $6.98 at 3GB, with the 7 day 5GB at $10.00 missing eSIM4’s price by just two cents. Validities skew short, with the 1GB lasting only 3 days.

The 50GB at $35.00 is the plan’s genuine draw for month-long heavy users.

Roamless treats data like a wallet rather than a bundle, topping up in fixed blocks that all stay valid for 30 days. For trips where plans might change mid-stream, that uniformity removes the expiry anxiety smaller plans carry elsewhere.

Pricing. Its 1GB at $3.95 is the closest anyone gets to eSIM4’s entry price while tripling the validity window. Beyond that it stays competitive without winning: $7.45 for 3GB and $10.95 for 5GB both sit above eSIM4, and $24.95 for 20GB undercuts eSIM4’s $25.98 by $1.03 but can’t touch Nomad’s $20.00.

How much data do you need in Denmark?

Danish travel runs on data more than cash: Rejseplanen plans your train and metro connections, the DSB app holds your rail tickets, and MobilePay settles everything from bakery queues to flea markets. Light users fit 1 to 3GB into a weekend, a typical week wants 5 to 10GB, and heavy streamers should think unlimited.

Light use: 1GB to 3GB

A weekend in Copenhagen with offline maps downloaded, messaging, and ticket apps runs comfortably inside 3GB. eSIM4’s 3GB at $6.98 covers this band for less than anyone else charges.

A typical week: 5GB to 10GB

Seven days of daily navigation, social uploads, video calls home and the occasional YouTube session lands in this band, which is the most common one-week purchase. eSIM4’s 5GB at $9.98 is the value pick.

Heavy use or long stays: unlimited

Streaming on the train to Aarhus, tethering a laptop for work, or any stay past two weeks burns through fixed plans fast. eSIM4’s unlimited range runs from 3 days at $9.98 to a full month at $69.98, and it’s the only provider covering the long end.

Denmark’s mobile networks and coverage

Three groups share the Danish market. YouSee (built on the old TDC network) holds the widest national reach, Telenor and Telia operate a shared radio network that performs strongly outside the biggest cities, and 3 (Three) concentrates capacity in urban areas.

Travel eSIMs like these route through that same national infrastructure, so coverage differences between brands come down to which carrier a provider partners with, not the brand itself. 5G is live across Copenhagen, Aarhus, Odense and Aalborg, with 4G LTE carrying almost everywhere else.

Denmark is flat, small and densely connected, so dead zones are rare by European standards; the thinnest service shows up on the smaller islands and on longer ferry crossings rather than in the countryside. eSIM4 connects to a major Danish network with 4G LTE and 5G, giving you the same underlying coverage the pricier household names rely on.

Why some cheap eSIMs feel slow or block apps

A few budget eSIMs cut costs by routing your traffic through servers in another country before it reaches the internet. That detour adds lag, drags speeds down, and confuses services that check your location: banking apps refuse to load, local offers vanish, and streaming catalogs switch countries without warning.

Before buying, confirm the eSIM hands you a genuine local Danish connection, especially if you’ll touch banking or government apps during the trip. eSIM4 connects locally on a major Danish network with 4G LTE and 5G, so your traffic stays in-country and your apps behave as they do at home.

eSIM vs airport SIM, pocket wifi and local SIM

A travel eSIM is usually the cheapest and simplest way online in Denmark: you install it at home, pay no deposit, and it wakes up the moment you land. The alternatives each have a place, and it’s worth knowing where.

  • Airport or physical SIM counters at Copenhagen Airport sell similar data at similar prices, but you’ll queue after a flight, swap out your home SIM, and lose your usual number until you swap back.
  • Pocket wifi means renting a router several people can share, which suits families, but you’re managing a daily rental, charging another device, and returning hardware before departure.
  • A local Danish eSIM from a carrier like YouSee or Telenor can include a Danish number, handy for local bookings, but it typically costs more than a travel eSIM and may involve ID checks or store visits.

For most travellers the travel eSIM wins on both price and convenience. And if a local number does matter, eSIM4’s Yabb app add-on supplies calls and texts without a separate SIM swap.

Will your phone work with an eSIM in Denmark?

You need two things: an eSIM-compatible phone and a carrier-unlocked one. iPhones from the XR and XS onward, Google Pixels from the 3 onward and Samsung Galaxy models from the S20 onward all qualify, along with most handsets released in recent years.

Dial *#06# to check: if an EID number appears on screen, your phone handles eSIMs. Some Settings menus also show an “Add eSIM” option directly.

Phones bought on carrier contracts sometimes ship locked, and a locked phone won’t accept a new eSIM, so unlock before you fly. Once it’s installed, your home SIM stays in place untouched: calls and texts to your normal number keep arriving while the eSIM quietly handles your data in Denmark.

How to set up your Denmark eSIM

Install before you fly, switch it on when you land, and the whole thing takes a few minutes.

  1. Buy your plan online and the QR code arrives by email within minutes.
  2. Open Settings, tap Cellular or Mobile Data, and choose Add eSIM.
  3. Scan the QR code and follow the prompts to install the plan.
  4. When you land in Denmark, set the eSIM as your data line and turn on data roaming for it.

If your Denmark eSIM will not connect

Most connection problems clear within a minute or two, so work through these in order.

  1. Step out of the aircraft into the arrivals hall, where the signal is real.
  2. Toggle airplane mode on and off to force a fresh network search.
  3. Confirm the eSIM is selected as your data line and data roaming is enabled for it.
  4. If no network has been picked, choose a Danish network manually in Settings.
  5. In crowded spots where 5G is congested, switch to 4G LTE for a steadier link.
  6. On some Android phones, enter the APN details from your provider’s instructions if data still won’t flow.

Travelling with one phone? Save the QR code as a photo before you leave: on iPhone you can long-press to add it later, and on Android Google Lens scans it straight from your gallery.

How we compared

We took each provider’s cheapest plan at every size and duration and benchmarked it against the field, comparing eight providers in total. Prices are in USD, collected in August and checked against each provider’s own Denmark pages.

eSIMply is excluded because it mirrors eSIM4 and isn’t an independent competitor, and free-trial tiers are excluded too. We recheck prices on a monthly cadence.

The goal is value for money at the size you’ll actually buy, not just the lowest sticker price on the page, which is why the price-per-GB table sits alongside the raw comparison.

FAQ

eSIM4 is the cheapest choice for the plans most travellers buy: $2.98 for 1GB, and the lowest price of any major provider at 1GB, 2GB, 3GB, 5GB and 10GB. Nomad undercuts it on 20GB ($20.00) and its 7 and 10 day unlimited plans, all shown openly in the tables above.

For most trips it’s eSIM4, which pairs the lowest small-plan prices from $2.98 with unlimited plans from $9.98 and 24/7 support. Nomad earns a look if you need 20GB of fixed data, and Airalo if you want a 50GB plan.

Yes, unless your home plan roams in Europe for free. A Danish travel eSIM starts at $2.98, installs in minutes before you fly, and connects the moment you land, so there’s no airport queue and no surprise roaming bill waiting at home.

From $2.98 for 1GB on eSIM4. Across the eight providers compared, 1GB plans run $2.98 to $4.99, a typical 5GB plan costs around $10, and unlimited starts at $9.98 for 3 days.

A weekend fits inside 1 to 3GB for maps, MobilePay and messaging. A week of daily navigation, social media and some streaming suits 5GB, while streamers and laptop tetherers should look at unlimited plans.

Yes. Every provider here rides on Denmark’s established national networks, so reliability comes down to coverage rather than the brand on the checkout page.

The bigger difference is speed and app behaviour, which depend on getting a genuine local Danish connection.

If your phone is eSIM-compatible and carrier-unlocked, yes. iPhones from the XR onward, Pixel 3 and later and recent Galaxy models all qualify, and dialling *#06# will show an EID number if yours supports eSIM.

These travel eSIMs handle data rather than issuing Danish numbers. If you need calls and texts, eSIM4 offers them as a paid add-on through the Yabb app, giving you a working number without swapping SIMs.

Yes. Phones that support eSIM keep your home SIM active for calls and texts while the eSIM line carries your data in Denmark, and you can flip between them in Settings whenever you like.

A local Danish eSIM comes from a Danish carrier and sometimes includes a Danish number, but it usually costs more and can involve ID checks or in-store signup. A travel eSIM is bought online in minutes and uses the same Danish networks for your data.

Yes. Your home SIM stays installed and switched on, so calls and texts to your usual number still reach you while the eSIM handles data behind the scenes.

The plan stops passing data until you top up or install another one, so nothing bills without your say-so. Picking unlimited, or one size up, sidesteps the problem entirely.

Install at home a day or two before flying, then switch the eSIM line on with data roaming once you land in Denmark. Activation itself takes a couple of minutes.

Not at 10GB: Nomad charges $16.00 against eSIM4’s $15.98. Nomad does win 20GB ($20.00 against $25.98) plus the 7 and 10 day unlimited durations. At 10GB and below, eSIM4 is cheaper, so the right call depends on how much data you’ll actually burn.

Yes. Danish networks run 5G across Copenhagen, Aarhus, Odense, Aalborg and most larger towns, with 4G LTE covering virtually everywhere else.

A 5G-capable phone picks it up automatically where it’s available.

For normal use, effectively yes. Providers apply a fair usage policy: full speed up to a daily high-speed allowance, then reduced speeds for the rest of that day before resetting the next morning.

Maps, messaging and browsing rarely come close to the cap.

Yes. eSIM4’s plans support tethering, so you can share data with a laptop or a travel partner’s phone.

If several people will lean on one connection regularly, an unlimited plan is the safer base.
