IoT SIM Coverage for Slovakia

Com4 IoT SIM cards connect to 3 networks in Slovakia on a single profile.

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.

One profile across Central Europe

Slovakia borders five countries. The same Com4 SIM works across 190+ countries and 750+ networks, so devices crossing those borders stay on one profile.

Built for assets that keep moving

Devices on cross-border freight routes stay on one Com4 profile, so trailers, containers and vehicles do not need a SIM swap when they leave the country.

Ready for the 2G and 3G shutdowns

Com4 publishes a shutdown tracker by country and network. Our SIMs carry LTE-M, NB-IoT, 4G and 5G on one profile, so capable hardware keeps working without a field visit.

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.

M2M hardware and a Test Lab

Com4 supplies M2M-grade hardware and runs a Test Lab, so module behaviour can be validated before a production deployment rather than after it.

What Our Customers Say About Com4's IoT Connectivity Solutions

"AI is transforming crop protection, but it depends on fast and reliable connectivity in every field. With Com4’s low latency and high speed IoT services, data flows seamlessly and software updates anywhere, driving smarter and more sustainable farming."

Kristian Kaurstad Morthen

Founder and CEO, Dimensions Agri Technologies

“It’s critical that the IoT connectivity just works. With Com4, it does – and that’s why we chose them.”

Bjørn Toreid

Founder and CEO, MedThings

"Com4 enables a reliable and efficient connection at all our customers’ stations. It is of the utmost importance for us to have a supplier who can guarantee that our communication works smoothly and reliably in all nine countries where we operate."

Malin Giselsson

Head of technology, Gomero

"It's often a tedious task to monitor machines that run as they should 99.5% of the time. With our solution based on Com4 technology, workdays are better, and we contribute to fewer cars on the road."

Ole Johan Aspestrand Bjerke

Managing Director, Soundsensing

“Com4 was the only company that showed the flexibility needed to handle the new CENELEC-protocol requiring a different form of communication with the electricity meters.”

Mohammad Ali Koteich

Head Engineer, Bane NOR

"Rapid and stable connectivity between the cages and the operations center is fundamental for the advancement of artificial intelligence."

Svein Erik Gregersen

Chief Operations Officer, Remora Robotics

"The solutions from Com4 are absolutely essential when sensor data from containers is transferred to the cloud."

Henrik Holen

Chief Commercial Officer, Sensorita

“Com4's IoT solutions have exhibited flawless performance, unlike other operators we have tested.”

Lars Lunde Birkeland

Commercial Director, Just Eat Norway

"The solution from Com4 makes it easy for us to get the old telephone devices online. All devices connect to a central web solution. This allows booth guardians across the country to update and upload audio files to the kiosks."

Jens Brynildsen

Managing Director, Maketronics

“For an entrepreneurial company, the expertise of Com4 has been invaluable in developing our GPS tracking technology – and has elevated our capacity in a way we are very grateful for.”

Tell us about your deployment in Slovakia and we will get back to you with coverage, pricing and a test kit.

Slovakia 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 NB-IoT deployed more widely here than LTE-M. For the live position in Slovakia, see our coverage tool and sunset tracker.

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.

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.

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 Slovakia is stated above, and we confirm it against your deployment. Given five land borders, check every country your devices reach.

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.
