FAQ
How do I know if I need a new system or just better devices?
If you're spending more time manually reconciling reports, or getting more alerts about devices going offline than about actual cargo movement, the problem is systemic. At that point, evaluating a dedicated GPS controlle...

At what scale do most container tracking systems start to fail?
Most systems show real strain at around 500-1000 actively tracked containers. That's where data latency and alert flooding overwhelm basic dashboards, and you need to move to dedicated fleet management software.

What is the biggest risk of using low-cost container trackers?
The biggest risk is data integrity failure during customs audits. Inconsistent location logs or missing timestamps can lead directly to delays, fines, and suspicions of tampering.

How accurate is GPS tracking for shipping containers at sea?
Accuracy degrades significantly at sea. Antenna placement inside metal containers and reliance on less frequent satellite pings often cause position errors over 100 meters, plus delayed updates.

When should I replace GPS devices that consistently fail in hilly terrain?
Replace devices when over 20% of your fleet shows repeated signal-loss events in the same geographic blackspots, despite APN and reporting interval adjustments. Focus on devices that consistently fail in specific corrido...

How long can a GPS device work without signal and what are the implications?
A GPS device can store data internally for days without signal, but live tracking halts. When connectivity resumes, delayed data dumps can cause timeline errors in fleet management software, making reports unreliable and...

What happens to geofence alerts when a GPS device loses signal?
Geofence alerts are typically queued and sent once connectivity resumes, but the delay can be hours. This makes time-sensitive notifications for entry or exit useless, creating significant safety and scheduling risks for...

Why do GPS trackers frequently lose signal in Indian hills and remote highways?
GPS trackers lose signal due to weak satellite visibility in steep valleys, poor cellular data coverage for transmitting location data, and network handoff issues between telecom towers in remote areas. Devices with basi...

When should I replace hardware versus fixing the SIM issue?
If the device is powered on and your platform shows its IMEI (but says it's offline), it's almost always a SIM or network problem. Only swap the hardware if the device won't power on at all, or if the SIM balance drains...

What's the difference between a prepaid and M2M SIM for tracking?
Prepaid SIMs need manual top-ups and can run out of balance, causing service interruptions. M2M (Machine-to-Machine) SIMs are built for business IoT applications—they usually have pooled data for all your devices, automa...

What happens to the location data when the SIM has no balance?
Most trackers have a small buffer in memory where they store recent GPS data temporarily. However, this data usually gets overwritten pretty quickly as new data is collected. The data from when the SIM was dead is typica...

How can I tell if my tracker's SIM has no balance?
The main clue is that data updates on your map and reports just stop. Your platform might show a 'communication lost' status, but not all systems give a specific warning for low balance. The vehicle's last known location...
