Static-IP IoT SIM for volume deployments
Private static IPv4, combinable with private APN, built for medium-to-large SIM fleets — not for single-unit pilots. Installation and configuration: €600 + VAT per project. Maintenance: €0.5 + VAT per month for each SIM with static IP active. For integrators who need their corporate firewall or SCADA platform to whitelist the device by address, on top of a fleet that's already sized.
Why iot.cards static IP is different
Published pricing, no approval committee
1NCE, Telefónica Tech and Wireless Logic handle static IP as an enterprise negotiation: annual contract, sales committee, custom quote. iot.cards publishes the price: €600 + VAT for installation and configuration, plus €0.5 + VAT per month per active SIM. Still a volume-oriented service, but you know the exact cost without going through a committee.
Private, in dedicated APN
Private IPv4 inside a dedicated APN for corporate infrastructure, SCADA, and retail video surveillance. The device stays within your network, reachable only from authorized hosts, without traversing the public Internet.
Combinable with private APN in the same project
Private static IP inside a dedicated APN is the standard architecture for SCADA and retail video surveillance. It's contracted alongside the private APN as part of the same installation project, with no separate negotiation beyond the agreed quote.
Added latency < 5 ms
Static-IP routing adds few hops when the SIM and GGSN sit in the same region. No proxies, no dynamic DNS, no client tunnels. For SCADA and telecontrol, added latency is negligible vs dynamic IP + DDNS.
Persistent assignment (never rotates)
The IP doesn't change on modem reboot or on IMSI switch between carriers. Lets your corporate firewall, SCADA platform or VMS whitelist the device by address with confidence the rule won't expire silently.
Firewall rules in the portal
Define inbound/outbound rules per SIM from the portal or API. Useful for restricting the device's reach to your platform without opening the whole range. Firewall event logs accessible for audit.
Cases where static IP is required, not optional
There are architectures where static IP isn't a nice-to-have but a functional requirement. The most frequent in Spain:
Inbound device access
- PLCs and industrial controllers reachable from a central platform
- IP cameras whose VMS pulls the stream (RTSP/HLS)
- Embedded servers accepting incoming connections
- Devices behind corporate firewall that whitelist by IP
Static-IP modes available
The differentiating factor vs a consumer SIM isn't the IP model, it's that on consumer you sit behind CGNAT and incoming ports are closed. iot.cards static IP is end-to-end routable, with no CGNAT and no ports blocked by default.
Technical capabilities of static IP
The static-IP layer is composed of several technical elements, contractable bundled or separately:
Private APN for private IP
For private static IP, the dedicated APN with your CIDR and IPSec/WireGuard tunnel is the standard architecture. Lets your corporate firewall treat the SIMs as its own subnet.

IP assignment, change and query via REST API. Per-SIM firewall rules. HMAC-signed webhooks on IP change (to sync your inventory).
API documentationRules and diagnostic portal
Bilingual web console for day-to-day management: see IP per SIM, define firewall rules, export event logs, diagnose inbound connectivity from a portal-based test.

- SCADA electricity and water smart metering
- IP cameras reachable from a centralized VMS
- Remote industrial PLCs (telecontrol)
- Embedded servers in connected machines
- SD-WAN routers with inbound traffic
- POS terminals with central system connection
- EV charging stations with inbound OCPP
- Telemetry with inbound connections (DASH7, modbus IP)
Pricing and lock-in
Static IP is billed in two parts: a one-time installation and configuration fee of €600 + VAT per project, plus €0.5 + VAT per month for each SIM with static IP active. There's no formal SIM minimum, but the installation fee means the service pays off mainly in medium-to-large deployments, not a single pilot SIM.
Installation and configuration
€600 + VAT, one-time per project. Covers setting up the dedicated APN, assigning the IP range and the initial firewall rule configuration.
Per-SIM maintenance
€0.5 + VAT per month for each SIM with static IP active, billed alongside data consumption. No lock-in: if you remove static IP from a SIM, it's stripped from next month's bill.
Enterprise (dedicated CIDR range)
Full CIDR range inside your dedicated private APN, custom quote. For large or regulated fleets where addressing must be your own and predictable.

Frequently asked questions about static IP for IoT SIM
- Does static IP require a minimum number of SIMs?
- There's no formal minimum, but installation carries a one-time €600 + VAT fee, so the service mainly pays off in medium-to-large deployments, not a single pilot SIM. To validate your use case before committing budget, book a technical call and we'll size the deployment with you.
- Does it work with CGNAT?
- You're not behind CGNAT on this SIM: we assign an end-to-end routable IP. That's the main operational difference vs a conventional consumer SIM, where you share a public IP with hundreds of devices and incoming ports are closed by default.
- IPv4 or IPv6?
- Static IPv4 by default. IPv6 available on demand depending on the use case and the underlying carrier network. Most IoT deployments still use IPv4 due to compatibility with legacy platforms and modems.
- Can it be combined with private APN?
- Yes, and it's the most common combination in industrial deployments: the private APN tunnels traffic to your infrastructure, and the static IPs inside that APN give each device stable addressing. Detail at /iot-sim-private-apn.
- Additional latency?
- Less than 5 ms in most cases. The route doesn't add significant hops when the SIM and the GGSN sit in the same region. For SCADA, telecontrol and video surveillance, added latency is irrelevant compared to the dynamic IP + DDNS alternative, which adds variable DNS resolution and periodic reconfigurations.
- Does the IP change if the SIM reboots?
- No. The IP is persistent: doesn't change on modem reboot or IMSI switch between carriers. What does change is the cell and technology (4G/5G/LTE-M), but the L3 IP stays stable.
- How is the static-IP add-on billed?
- In two parts: a one-time €600 + VAT installation and configuration fee per project, and €0.5 + VAT per month for each SIM with static IP active, separate from data consumption. No lock-in on the monthly component: if you remove static IP from a SIM, it's stripped from next month's bill.
- What sets it apart from 1NCE or Telefónica Tech enterprise offering?
- Two things: (1) published, fixed pricing (€600 + VAT installation, €0.5 + VAT per SIM per month), no approval committee or custom annual contract negotiation; (2) on-demand contractable from the portal or API once the deployment is sized, without the commercial red tape of a classic enterprise account. Still a volume-oriented service, not built for loose single SIMs.
