Why Com4’s IoT SIM Card for Denmark?
Non-steered SIM
Com4 SIMs are non-steered and carrier-agnostic. The modem connects to the strongest signal available rather than defaulting to one partner network.
Run by a Nordic operator
Com4 is a Norwegian MVNO based in Oslo, part of Wireless Logic Group, and holds the official Made in Norway label. Support operates in your timezone.
One profile from Denmark into the EU
The same SIM works across 190+ countries and 750+ networks, so devices crossing the Danish border into Germany or Sweden stay on one profile.
LTE-M and NB-IoT on the same SIM
Com4 supports LTE-M, NB-IoT, 4G and 5G on one profile, so metering, tracking and gateway deployments can share a single connectivity contract.
Pilot to national rollout
No minimum contract. Pay-as-you-go or data pooling. You pay for active SIMs only, with data from EUR 0.001/MB and volume discounts as you scale.
Ready for the 2G and 3G shutdowns
Com4 publishes a shutdown tracker by country and network, and our SIMs fall back across technologies on one profile so capable hardware keeps working.

Try Com4 IoT SIMs in Denmark at no cost
Test how our SIMs perform in your own hardware before you buy anything. The kit is free, comes with no contract, and takes a few minutes to request.
What the free test kit includes:
- Up to 5 SIM cards per applicant
- 100 MB of data per SIM per month, usable within the EU
- A 60-day validity period
- eSIM form factor available on request
- 2G, 3G, 4G, 5G, LTE-M and NB-IoT all supported on a single SIM
Worth testing across the German land border too, since the same profile continues without a swap.

IoT SIM Card for Denmark – Frequently Asked Questions
What is the state of IoT in Denmark?
Denmark is an EU member state, so EU electronic communications rules apply. The defining change right now is the 2G and 3G withdrawal, which runs per network and decides what hardware is still viable. Regionally, GSMA data shows both LTE-M and NB-IoT are widely available. For the live position in Denmark, see our coverage tool and sunset tracker.
Should I use NB-IoT or LTE-M for a deployment in Denmark?
NB-IoT suits static endpoints sending little data on a long battery life. LTE-M holds a session through cell handover, so it suits anything that moves. One catch: LTE-M has wholesale roaming agreements while NB-IoT lags, so NB-IoT devices can reach fewer networks. Com4 SIMs carry both.
When are 2G and 3G being switched off in Denmark, and what happens to my devices?
There is no single national date. Timelines run per network, so check our 2G and 3G sunset tracker, filterable by country and network. Devices with LTE-M, NB-IoT or 4G fall back on the same Com4 profile without a site visit. 2G-only modules need replacing, and we will audit yours.
Do I need to register IoT SIMs in Denmark, and is permanent roaming allowed?
Rules diverge across Europe, and permanent roaming is not treated uniformly even inside the EU. Some countries require IoT SIM registration, some exempt machine-only SIMs, a few restrict permanent roaming. Com4's position for Denmark is stated above, and we confirm it against your deployment. Given assets cross the German land border regularly, check every country your devices reach.
How do I test Com4 connectivity in Denmark before committing?
Order a free test kit: up to five SIM cards, 100 MB per SIM per month, 60-day validity, eSIM on request, and 2G through 5G plus LTE-M and NB-IoT on every SIM. Five SIMs lets you test more than one hardware variant at once. There is no minimum contract.
