IoT SIM for fleets, GPS and vehicle telematics

Multi-carrier SIM with EU+UK roaming and no permanent-roaming restriction, for GPS tracking, FMS telematics, smart tachograph, e-CMR and dashcams. The SIM doesn't disconnect when your truck crosses the border for 90 days, doesn't expire on inactivity and is bulk-managed by API. Failover across Movistar, Vodafone and Orange in Spain.

Fleet coverage in Spain and Europe

The SIM connects to the three Spanish networks (Movistar, Vodafone, Orange) and, as soon as the vehicle crosses the border, roams on 750+ networks across 190+ countries. In EU and UK the rate is similar to domestic; in other zones it's published per country.

For standard GPS tracking, 4G LTE is the default technology; LTE-M is used for low-power loads (dry box, container telemetry). 2G/3G are in sunset across Spain and Europe — for new fleets, avoid modems that only support 2G/3G.

Typical fleet use cases

• Commercial GPS tracking (light and heavy vehicles)
• Smart tachograph remote download and periodic file pickup
• e-CMR and electronic delivery notes
• 4G/5G dashcams with on-demand video
• FMS with CAN bus (fuel, RPM, AdBlue, driving times)
• Refrigerated trailer monitoring (cold chain)
• Rental fleets and car sharing (telemetry + remote unlock)
• Last-mile delivery (rider tracking, POD)
• Construction and earth-moving machinery
• International EU logistics (long-haul truck)

Frequently asked questions about IoT SIMs for fleets

Does the SIM stop working if the truck spends 6 months outside Spain?

No. iot.cards M2M SIMs aren't subject to the 90-day fair-use cut-off that affects European consumer SIMs. The vehicle can spend months outside the issuing country without the SIM disconnecting or the visited carrier's retail rate kicking in. This is the key difference for international fleets that, with consumer SIMs, start seeing silent disconnects after a few weeks.

EU and UK coverage post-Brexit?

Yes. After Brexit, UK is still reachable on roaming at rates similar to the EU; per-MB cost across EU+UK is comparable to Spanish domestic. M2M SIMs aren't covered by the BEREC consumer roaming regulator, so they don't have the European fair-use cut-off either. For vehicles regularly transiting UK, connectivity is transparent.

Pooled data across all vehicles?

Yes, on pooled plans. You contract a fleet-wide data bundle (e.g. 100 GB/month for 50 vehicles) and SIMs share that bundle: high-mileage drivers compensate parked vehicles. Avoids the typical waste of per-SIM bundles (half are unused, the other half burn through).

How do I bulk-provision 200 SIMs by API?

POST /sims accepts batches in CSV or JSON with ICCID, plan, tags (plate, driver, route) and optionally private APN. The API is idempotent on ICCID, returns a job_id for progress polling and emits HMAC-signed webhooks on batch completion. Docs at /plataforma/api. You can also drag-import a CSV from the portal.

Static IP for dashcam access?

Yes, public or private static IP as add-on. Lets your video platform pull the RTSP or HLS stream from the vehicle (inbound access). Technical detail at /productos/sim-ip-fija. For large fleets, private static IP within a private APN is the standard architecture.

Private APN to my TMS or corporate system?

Yes. We provision a dedicated APN with your CIDR range (RFC1918) and an IPSec or WireGuard tunnel into your VPC on AWS, Azure, GCP or your on-prem DC. Your 200 vehicles send telemetry without traversing the public Internet, which simplifies audit and reduces attack surface. Detail at /productos/apn-privado.

Data-only or also voice/SMS?

Data-only by default (the standard in vehicle telematics). SMS available as an add-on for specific cases (driver notification, two-way panels with HQ). Voice isn't enabled on M2M.

Compatible with smart tachograph?

Yes. The second-generation V2 smart tachograph uses cellular connectivity for remote DDD file download and authority reporting. The M2M IoT SIM is compatible with the main vendors (VDO, Stoneridge, Continental). If your FMS integrator needs specific configuration data (APN, authentication), we provide it during onboarding.

What happens if the SIM has no network for 30 days (vehicle in workshop)?

Nothing. The SIM doesn't expire on inactivity or get disconnected. The vehicle leaves the workshop, the SIM auto-attaches as soon as it gets signal and resumes reporting. Nothing to manually reactivate. That's a meaningful difference from recycled consumer SIMs, which can be deactivated after periods of inactivity.
