The M2M SIM card built for teams who want full control
One SIM, the strongest signal in every market
Com4's IoT SIM cards are carrier-agnostic and non-steered: a device attaches to the network with the strongest, most reliable signal available wherever it is, not the network a traditional single-carrier SIM would default to. Multiple network operators are available per country for resilience, and eUICC lets you provision new profiles remotely, Over-the-Air, without a truck roll or a card swap.
- Centralized device control through Polaris CMP
- Built for developers with REST APIs, webhooks, and STOMP streaming
- Secure by design: TLS encryption, RBAC, audit logs, hosted in Norwegian data centers
Expand without new contracts
Enter a new market with the same SIM and the same SKU for every device. No local carrier negotiations, no new supply chains to manage.
Best available signal, everywhere
Non-steered network selection means fewer dead zones and faster registration, wherever a device travels
Control cost and behavior
Pay only for the data you use, from market-based rates starting at €0.001/MB. Choose pay-as-you-go or data pooling, with no minimum contract durations and no hidden costs
Freedom to switch operators
Stay in control of your connectivity. If your needs evolve, you can change operators without being locked into a single carrier relationship
One profile, ready out of the box
Com4 SIMs can be delivered pre-activated, so devices connect the moment they're powered on, with no manual activation step in a connectivity platform.
Deep roaming expertise
Permanent roaming is a core area of Com4's expertise, including navigating country-specific regulations and operator agreements for long-term international deployments.
See into the network and every device
Catch issues before they turn into support escalations. Polaris CMP gives you direct network-level visibility into device status and connectivity behavior, so you can troubleshoot without a site visit or a support ticket.
- Full network insights: real-time visibility into connectivity status, device activity, and data usage across all networks
- SIM diagnostics & troubleshooting: advanced tools to quickly identify and resolve connectivity issues
- Smart alerts: automated monitoring with real-time notifications for IMEI mismatches, unusual usage, or SIM state changes
- Advanced insight tools: dashboards and reports that turn network performance and device behavior into decisions
Every form factor, one global profile
Pick the format your hardware needs. The connectivity behind it is exactly the same, whether you're running a pilot batch or millions of connections.
All SIMs support class A (5V), B (3V), and C (1.8V) supply voltages, and industrial-grade variants are built for 10+ years of maintenance-free operation. Com4 was the first IoT operator in Europe to implement GSMA-compliant eUICC eSIM subscription management, and executed Europe's first successful IoT SIM profile swap.

"The ability to manage multi-carrier connectivity through a single interface, combined with flexible data plan options, customer-controlled SIM management, and automated usage tracking and billing, has significantly improved our operations."
"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."
"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."
