How do you get a mobile phone number in Denmark in 2026?

Q: How do you get a mobile phone number in Denmark in 2026?

Buy a prepaid Danish SIM or eSIM from Lebara, Lycamobile, Oister, CBB, or a supermarket kiosk on day one. Prepaid usually needs only a passport, so you can activate a +45 number before CPR and banking finish. Shops may still ask to see ID. Switch to a postpaid plan with YouSee, Telenor, Telmore, or 3 later when you have CPR, MitID, and a Danish account for cheaper long-stay data.

A Danish +45 number is infrastructure, not a luxury. MitID SMS checks, bank OTPs, MobilePay, and landlord calls expect a local line. Get prepaid first, then tidy the tariff once paperwork settles.

What is the fastest first-week path?

Buy a prepaid starter SIM or eSIM from Lebara, Lycamobile, Oister, or CBB at Netto, Føtex, 7-Eleven, airport kiosks, or operator shops. Prepaid generally does not require a CPR number or a Danish bank account, though a clerk may still glance at your passport. Activate with an outbound call or the operator app, then top up.

Keep the packaging until the number works for SMS codes used in MitID and bank onboarding. Travel eSIMs help data in week one, but they do not give you a Danish number for MitID or MobilePay.

When should you move to a contract?

After CPR and MitID, postpaid plans from YouSee, Telmore, Telenor, or 3 usually offer more data for less money and cleaner MobilePay pairing. Expect CPR, MitID login, and a Danish payment method. Port the prepaid number when you can so banks and employers do not need a new contact.

Coverage is strong in Copenhagen and Aarhus cores; rural Jutland and islands can feel thinner on some challenger brands that ride the 3 network: Living in Copenhagen and Living in Aarhus. Fold the phone line into the wider arrival order in Paperwork after moving.

Common misconceptions

Assuming you need CPR to buy any Danish SIM fails. Prepaid is built for arrivals.

Assuming a foreign number works for every MitID and bank SMS flow also fails. Get +45 early even if you keep a home SIM for roaming.

Summary

Buy a prepaid +45 SIM with your passport on arrival, use it for MitID and banking SMS, then switch to a CPR-backed subscription once the account and digital ID are live.
