Use cases
Typical problems
- Pallets and containers go dark crossing borders: a single-operator SIM loses an acceptable roaming agreement and the device stops reporting for days mid intercontinental route.
- Pharma cold chain traceability (GDP) requires continuous temperature logging between +2 and +8 °C; a single 30-minute coverage gap without enough buffer compromises the regulatory validation of the shipment.
- Trackers inside an ocean container have no satellite line of sight and no cellular coverage for weeks at sea; they need dual cellular + satellite (Iridium SBD) mode that blows up SIM cost if not managed well.
- Theft of high-value cargo (electronics, pharma, tobacco) where the thief drops the load into a Faraday cage or kills the SIM; demands tracker geographic redundancy and route-deviation alerts.
- Customs holds shipments for days: the tracker keeps transmitting and burns the data plan while the cargo doesn't move, generating unexpected bills.
- Single-use sensors (disposable loggers like Sensitech TempTale) vs reusable trackers: a tradeoff between per-shipment cost and badly sized initial CAPEX.
Recommended architecture
- 1
Asset tracker with multi-operator eUICC SIM and Sigfox or satellite (Iridium SBD) backup
The cellular SIM handles 95% of the journey; the Sigfox or Iridium module takes over on open sea, remote zones, or whenever the cellular link is down for more than N hours. eUICC swaps profile OTA when crossing regions (EU -> APAC) without touching the device.
- 2
Cold chain logger with NIST-calibrated sensor and CFR 21 Part 11 certification
Sensitech, Tive, Sensorlink or Roambee probes with traceable calibration certificate. The log is cryptographically sealed so it's admissible in GDP / GMP audits. NB-IoT or LTE-M connectivity to minimize consumption on long shipments.
- 3
Pooled data plan with aggregated allowance and per-unit usage alerts
5,000 trackers sharing a 50 GB pool instead of 5,000 individual contracts. Some shipments use 1 MB, others 50 MB; the pool absorbs the variance. Alerts at the aggregate level and at the individual SIM level prevent surprise bills from a runaway tracker.
- 4
Integrated TMS / cargo visibility platform (project44, FourKites, Shippeo, Roambee, Tive Insight)
Tracker data feeds a supply-chain visibility platform that cross-references the TMS, the ERP and the customs manifest. Events like container open, route deviation or thermal excursion trigger workflow to the logistics supervisor.
- 5
Geofencing per hub, port and customs with automated event logging
Every logistics hub, port or customs terminal is geofenced. Asset entry and exit are recorded without manual scanning, feeding transit-time KPIs and detecting anomalous waits (>72 h in customs is a red flag).
Indicative data plan
| Device | Typical monthly traffic | Recommended plan |
|---|---|---|
| Disposable pallet tracker (Sensitech TempTale GEO, Tive Solo Lite) | 5-20 MB/shipment | Pooled pay-as-you-go |
| Reusable container tracker (Roambee BeeAware, Sensolus, ORBCOMM CT 1000) | 30-80 MB/month | Pool 100 MB/SIM |
| Pharma cold chain logger (Sensitech TempTale, ELPRO Liberty) | 10-30 MB/shipment | NB-IoT plan 50 MB |
| Hybrid satellite tracker (Iridium Edge, Globalstar SmartOne C) | 5-15 MB cellular + satellite per message | Hybrid cellular + satellite SBD plan |
| RFID readers at hub / cross-docking | 100-500 MB/month | 500 MB pack / static IP |
Indicative figures for 3-15 day shipments. Trackers reporting on event (shock, opening, thermal excursion) consume far more; fixed-cadence trackers (every 1-6 hours) are more predictable. Request a sizing simulation with your typical OD-pair.
When to use static IP
- The end customer mandates EDI / API integration from a known source IP allowed in their firewall (common in pharma, defense and public administration).
- Hub RFID readers or gateways receive inbound connections from the WMS for real-time cross-docking operations.
- Chain-of-custody audit (high-value cargo, diplomatic pouch, controlled pharmaceuticals) requires per-IP traceability in the event log.
When to use private APN
- 3PL/4PL operators that handle data from multiple shippers and need to segment traffic per customer without exposing it to the Internet.
- Pharma GDP compliance with validated manifests: the logger connection to the validation system always goes through a private tunnel, never the public Internet.
- Trackers for classified cargo (defense, hazardous chemicals under ADR, hazardous waste) where regulation demands a private network with RFC1918 addressing.

Frequently asked questions
- Why do I need a multi-operator SIM for cargo tracking if the freight stays inside the EU by road?
- Because there are still gray roaming zones inside the EU in 2025: cabotage, transit parking in countries without the shipper's operator coverage, exchanges at international hubs. A single-operator SIM goes dark for hours at crossings like Brennero (AT/IT), the Channel Tunnel or the Mediterranean corridor between ES and FR. A multi-IMSI switches automatically and the event isn't even logged as an incident.
- How do I handle pharma cold chain when the tracker loses coverage for hours?
- The logger needs an internal buffer (minimum 7 days of samples at 1 sample/15 min) and must cryptographically sign every reading. When coverage returns it uploads the entire history with the original timestamps; the validation system reconstructs the full thermal curve. Without a buffer, GDP rejects the shipment. Verify logger memory before buying — many cheap models only store 24-48 h.
- When does a disposable tracker make more sense than a reusable one?
- Disposable (Sensitech TempTale, Tive Solo Lite) if per-shipment cost is low (<$25), there's no reliable reverse logistics or the shipment goes to the end customer. Reusable (Roambee, Sensolus, ORBCOMM) if unit cost runs $200-400, there's rotation between your hub and customers, and you can guarantee return. Typical break-even: 20-30 trips per unit per year.
- Will my cellular tracker work on open sea or in a ship's hold?
- No. Cellular coverage extends 5-10 nautical miles from the coast. For the maritime leg you need a hybrid tracker with a satellite module (Iridium SBD or OGx, Globalstar simplex). It reports less frequently (every 6-12 hours instead of every 30 min) and per-message cost is 10-100x cellular, but it guarantees door-to-door visibility.
- How do I keep customs from draining the tracker's data plan?
- Configure adaptive cadence: when the tracker enters a customs geofence, drop to a report every 6-12 hours instead of every 30 minutes. Cargo in customs doesn't move so you don't need fine route data. Some trackers ship with programmable 'idle vs moving' profiles. Combine with a >48 h customs-hold alert that escalates to the broker.
- Who is liable if the tracker reports a thermal excursion but the shipment looks fine?
- Depends on the SOP between shipper and carrier. The norm: a calibrated, signed logger reading prevails over visual inspection. If it reports >+8 °C for more than 30 minutes in pharma, the shipment is quarantined pending manufacturer analysis. That's why traceable NIST sensor calibration and tamper-evident logging are critical; a badly calibrated sensor triggers false excursions that cost thousands of euros.
