Why Com4’s IoT SIM Card for Hungary?
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
Hungary borders seven countries, more than any other state in this region. The same Com4 SIM works across 190+ countries, so devices crossing those borders 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 low-power sensors and high-throughput gateways can share a single connectivity contract.
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.
Every SIM visible in Polaris
Polaris CMP gives real-time monitoring and usage tracking across your fleet, with API access so SIM management fits into systems you already run.

IoT SIM Card for Hungary – Frequently Asked Questions
What is the state of IoT in Hungary?
Hungary 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 Hungary, see our coverage tool and sunset tracker.
Should I use NB-IoT or LTE-M for a deployment in Hungary?
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 Hungary, 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 Hungary, 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 Hungary is stated above, and we confirm it against your deployment. Given seven land borders, check every country your devices reach.
How do I test Com4 connectivity in Hungary 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.
