I got a prepaid SIM in my first week, long before my CPR number arrived, and it’s still what I’d recommend. Once you’re registered, a proper plan gets you far more data for the money. We compared the plans on each provider’s own website on 18 October 2026; the tables below show what we found.
Quick answer
- Just arrived, no CPR or MitID yet: get a prepaid Lyca SIM or eSIM. 5 GB costs 19 kr per 30 days, registration is optional, there’s no binding, and you get a real Danish number. Lebara is the other well-known prepaid brand.
- Settled, with CPR and MitID: Flexii (150 GB for 99 kr/month after the intro) and OiSTER (100 GB for 109 kr/month after the intro) were the best value we found.
- Unlimited data: Flexii’s unlimited plan is 144 kr/month after the intro (2 TB fair-use cap), the cheapest unlimited plan in our check.
- Short visit, data only: a travel eSIM such as Airalo works, but for anything longer than a couple of weeks a Lyca eSIM is far cheaper and gives you a Danish number.

“Normal price” is the monthly price after any intro offer, as listed on each provider’s site on 18 October 2026. Most subscriptions start with a cheaper intro period, so you’ll often pay less at first. “Without CPR?” means whether you can realistically sign up before you have a CPR number and MitID; subscriptions usually ask for both at checkout (CBB states it outright). Confirm the final price at checkout.
Prepaid SIM in Denmark: the first-week option
Most subscriptions need CPR, MitID and automatic card payment, which you won’t have in your first days. A prepaid SIM (in Danish: taletidskort or simkort uden abonnement) gets you a working Danish number straight away, so you can receive bank codes, landlord calls and job messages while you sort out your first-week paperwork.
Lyca: our first-week pick
Lyca’s smallest bundle, All in One 19, costs 19 kr per 30 days for 5 GB of Danish data, 4 GB of roaming data in the EU, Ukraine and Moldova, and 5 hours of calls, with 5G included. It renews every 30 days until you switch auto-renewal off, and there’s no binding. Lyca’s own FAQ says registration is optional, physical SIMs are delivered free, and you can pick an eSIM instead (Lyca All in One 19, checked October 2026). Bigger bundles go from 30 GB up to 500 GB per 30 days. Lyca’s bundle page showed campaign prices on several of them during our check, so confirm the price in the basket.
| ✅ Pros | ⚠️ Watch out |
|---|---|
| No CPR needed; registration optional | Mixed customer support |
| eSIM and 5G included | Auto-renews every 30 days |
| Includes international call minutes | Less data per krone than a subscription |
Lebara
Lebara is the other big prepaid brand in Denmark and is popular for cheap calls to other countries. Lebara changes its bundles and campaign prices often, so we don’t quote a price here. Check the current bundles, eSIM support and ID rules on Lebara’s site before you buy.
| ✅ Pros | ⚠️ Watch out |
|---|---|
| Prepaid, no contract | Current prices not confirmed by us |
| Known for cheap international calling | Support is basic |
Where to buy a SIM card in Denmark (Copenhagen, airport, near you)
- Online, before you fly: the most reliable route. Lyca sends physical SIMs for free, or you can install an eSIM on Wi-Fi and be online the moment you land.
- Convenience stores and supermarkets: prepaid starter packs are commonly sold at 7-Eleven shops (you’ll find them at Copenhagen Central Station, Aarhus H and most city centres), kiosks and some supermarkets. Stock varies by shop and we haven’t checked individual stores, so have the online option as a backup.
- Copenhagen Airport: you can find SIM cards on arrival, but travel guides consistently warn that airport prices are higher and data allowances smaller. If your phone supports eSIM, it’s cheaper to buy online.
- Subscriptions: every subscription in this guide is ordered online, with CPR, MitID and a payment card.
Best eSIM for Denmark
Searching “best eSIM for Denmark” mostly turns up travel eSIM sellers. Which one is right depends on how long you’re staying.
| Option | Price we saw | Danish number? | Best for |
|---|---|---|---|
| Lyca eSIM (prepaid) | 5 GB: 19 kr / 30 days | Yes | New arrivals staying for months |
| Airalo Denmark eSIM | Unlimited: €24.50 for 7 days, €65.50 for 30 days | Not listed (treat it as data only) | A short visit or the first few days |
| Danish subscription eSIM (OiSTER, eesy, DUKA, Telmore and others) | See the comparison table | Yes | Once you have CPR and MitID |
Our take: if you’re moving to Denmark to study, a travel eSIM only makes sense for the first days. A month of unlimited Airalo data costs €65.50 (roughly 490 kr), against 19 kr for Lyca’s 30-day 5 GB bundle, and you still won’t have a Danish number for MitID, banks or landlords. Airalo’s Denmark plans run on the 3 network, according to its own page (Airalo Denmark, checked October 2026).
Once you have CPR, eSIM is standard: OiSTER says its eSIM is free, eesy lets you choose eSIM when you order, and DUKA and Telmore both offer it on compatible phones.
After you’re settled: the cheapest mobile plans in Denmark
With CPR and MitID you can get far more data for the money. All the plans below have no binding according to the providers. Prices are from each provider’s site on 18 October 2026.
Flexii: most data for the money
Flexii runs on 3’s network. Its 4G plans are 59 kr for 20 GB, 79 kr for 50 GB and 99 kr for 150 GB per month after a six-month intro (44, 59 and 74 kr). Unlimited data is 144 kr on 4G or 149 kr on 5G after the intro, with a 2 TB fair-use cap. 5G versions of the GB plans cost 10 kr more. The intro prices on the GB plans had an order deadline of 26 October at the time of our check (Flexii offers).
| ✅ Pros | ⚠️ Watch out |
|---|---|
| Cheapest unlimited plan we found | Cheapest plans are 4G only |
| 150 GB for under 100 kr | “Unlimited” has a 2 TB cap |
| Six-month intro price | Needs CPR + MitID |
OiSTER: best 5G value
OiSTER also uses 3’s network, and every plan includes 5G. We saw 40 GB at 49 kr for the first 3 months, then 99 kr; 100 GB at 54 kr, then 109 kr; and unlimited data at 99 kr, then 199 kr. There’s also a 12 GB plan for 69 kr. The eSIM is free (OiSTER plans).
| ✅ Pros | ⚠️ Watch out |
|---|---|
| 100 GB 5G for 109 kr | Needs CPR + MitID |
| Free eSIM | 3 network (fine, but not TDC or TT) |
| 30 to 40 GB of EU data | Phone bundles come with 6-month binding |
DUKA (dukaTALE): best if you travel
DUKA gives you separate data for Denmark and for 39 other countries, with 5G and eSIM. Normal prices: 30 GB in Denmark plus 30 GB abroad for 99 kr (55 kr for new customers on a campaign that runs until 31 March 2027), 120 GB for 119 kr, 200 GB for 129 kr and 1,000 GB for 179 kr. No binding and no fees, according to DUKA (dukaTALE plans).
→ Get DUKA
Greentel: small plans for light users
Greentel suits you if you mostly use Wi-Fi at home and on campus. 5 GB with 5 hours of talk is 55 kr, 10 GB with unlimited talk is 69 kr, 50 GB is 99 kr and 100 GB is 119 kr, all with 5G and no binding (Greentel plans).
CBB: longest half-price intro, TT network
CBB was running half price for 6 months when we checked: 40 GB for 64 kr (then 129 kr), 50 GB for 69 kr (then 139 kr), 100 GB for 74 kr (then 149 kr) and unlimited data for 109 kr (then 219 kr). It runs on the TT network shared by Norlys and Telenor (CBB plans). After the intro it’s pricier than Flexii or OiSTER, so it’s worth setting a reminder to compare again at month six.
| ✅ Pros | ⚠️ Watch out |
|---|---|
| Six months at half price | Needs CPR + MitID |
| No binding | Price doubles after the intro |
| TT network coverage |
→ Get CBB
eesy: budget plans on TDC’s network
eesy runs on TDC NET’s network with 5G and eSIM. When we checked: 40 GB for 64 kr for 3 months, then 129 kr; 80 GB for 74 kr, then 149 kr; unlimited data for 109 kr, then 219 kr. No binding (eesy).
→ Get eesy
Telmore: the big brand on TDC’s network
Telmore is one of the best-known brands in Denmark and uses TDC NET’s mobile network. Normal prices: 45 GB with unlimited talk for 149 kr, 60 GB with Telmore Musik for 179 kr and unlimited data for 249 kr. There’s also a small 3 GB plan for 79 kr, and Telmore GO, a pay-as-you-go plan at 39 kr/month plus usage (Telmore plans). It’s not the cheapest, but it often runs short intro campaigns.
| ✅ Pros | ⚠️ Watch out |
|---|---|
| Strong TDC network coverage | Needs CPR + MitID |
| Unlimited talk on the main plans | Pricier than budget brands |
| eSIM on compatible phones |
Call me
Call me is Norlys’s budget brand on the TT network. Its 30 GB plan was shown at 129 kr with a “half price for the rest of the year” campaign, and the page didn’t make clear which price applies afterwards, so check at checkout (Call me plans). → See Call me
YouSee: if you also want TV or home internet
YouSee is the largest telecom brand in Denmark and runs on TDC’s network. It’s rarely the cheapest for mobile alone, but bundling mobile with YouSee home internet or TV can bring the total down. If you need home internet too, see our internet guide.
Danish mobile networks in 2026: Telia is now Norlys
Ignore older guides that list “Telia” as a Danish brand. Norlys bought Telia Denmark in 2024, including Telia’s half of the shared TT network, and the Telia brand was renamed Norlys in May 2025. Existing customers kept their SIM cards, products and prices, and Call me continued as a Norlys brand (Mobilsiden, 5 May 2025).
Denmark has three mobile networks:
- TDC NET: used by YouSee, Telmore and eesy.
- TT network (shared by Norlys and Telenor): used by Norlys, Telenor, CBB and Call me.
- 3: used by 3, OiSTER and Flexii.
Coverage is good across the country on all three, so for most students price, data and whether you can sign up on arrival matter more than the network. If you live somewhere rural, check the provider’s coverage map for your address.
The CPR / MitID barrier
Subscriptions usually require CPR, MitID and automatic card payment. That’s why a prepaid SIM is the practical first step. It keeps you connected while you sort out CPR, MitID, a bank account and NemKonto, and then you can move to a cheaper big-data plan and keep the same number (see below). Our must-have apps guide covers the apps you’ll want on the phone once it works.
EU roaming and calling abroad
- EU roaming: Danish plans include “roam like at home” in the EU, but the EU data allowance is set per plan. On the plans we checked it ranged from 4 GB (Lyca 19) to 49 GB (Telmore unlimited). Since 1 January 2026, Ukraine and Moldova are part of the EU roam-like-at-home area (Council of the EU).
- Outside the EU: usually charged separately. DUKA includes data in 39 countries, and CBB and Call me sell “World” plans that cover a few countries outside the EU.
- Calling home: Lyca’s bundles include international minutes (2 hours on the 19 kr bundle). On most subscriptions, calls from Denmark to other countries cost extra.
- Travel insurance: if you travel a lot, see our travel insurance guide.
Keeping your number when you switch
Sign up with the new provider and ask them to transfer (port) your number. Don’t cancel with your old provider first, or the number can be lost. Lyca says a transfer typically takes 1 to 3 working days. Some providers default to your old provider’s notice period unless you ask for an immediate move, so check the switch date when you order.
Kurz auf Deutsch: SIM-Karte für Dänemark
Für einen kurzen Besuch reicht eine EU-SIM mit Roaming oder eine Reise-eSIM. Wer länger bleibt, bekommt bei Lyca eine dänische Prepaid-SIM oder eSIM ohne CPR-Nummer (5 GB für 19 kr pro 30 Tage). Ein dänisches Abonnement braucht in der Regel CPR und MitID.
FAQ
Can I get a Danish SIM card without CPR or MitID?
Yes. Lyca’s prepaid SIM and eSIM don’t require registration, according to Lyca. Most subscriptions ask for CPR, MitID and a payment card.
What’s the cheapest SIM card in Denmark?
For a working number, Lyca’s 5 GB bundle at 19 kr per 30 days. For lots of data once you’re settled, Flexii’s 150 GB plan at 99 kr/month and OiSTER’s 100 GB plan at 109 kr/month (both after the intro) were the best value we found. The cheapest unlimited plan was Flexii’s at 144 kr/month.
How much does a SIM card cost in Denmark?
The SIM itself is often free: Lyca delivers physical SIMs at no cost, and OiSTER’s eSIM is free. You pay for the bundle or plan, from 19 kr per 30 days prepaid or about 55 to 150 kr a month for a subscription.
Where can I buy a SIM card near me in Copenhagen?
7-Eleven shops and kiosks commonly sell prepaid starter packs, and there are SIM sellers at Copenhagen Airport, though airport prices tend to be higher. Ordering a Lyca SIM online or installing an eSIM is the most reliable option.
What’s the best eSIM for Denmark?
For students or anyone staying more than a couple of weeks, a prepaid Lyca eSIM: it’s cheap and includes a Danish number. For a short trip, a travel eSIM such as Airalo is data only but quick to set up. Once you have CPR, most Danish subscriptions offer eSIM.
Can I get a Danish eSIM with a phone number?
Yes. Lyca’s eSIM comes with a Danish number, and so does any Danish subscription with eSIM. Travel eSIMs like Airalo don’t list a phone number on their Denmark page.
Lebara or Lyca?
Both are prepaid and contract-free. We recommend Lyca for your first week because we could confirm its current price, optional registration and eSIM on its own site. Lebara’s bundles change often, so compare its current offers before you buy.
What’s the best mobile network in Denmark?
Denmark has three networks (TDC NET, the TT network of Norlys and Telenor, and 3), and all cover the country well. Choose on price and data unless you live somewhere with a known weak spot.
Can I keep my number if I switch?
Yes. Sign up with the new provider and let them request the transfer, and don’t cancel with the old one first. Lyca says it typically takes 1 to 3 working days.
Prices checked on providers’ websites on 18 October 2026. Danish SIM prices change constantly, especially intro campaigns, so always confirm the final plan and price at checkout before you buy. More money-saving tips are in our student budget guide.
