Portable GPS vs fixed GPS vs SIM tracking: which one for which truck?
There is no single right answer. The right tracking method depends on whether you own the truck and how often it changes.
| Fixed GPS (wired) | Portable GPS device | SIM-based location | |
|---|---|---|---|
| Installed | Permanently, in the vehicle | In the cab for one trip | Nothing; uses the driver’s phone network |
| Best for | Your own fleet | Hired and market trucks | Trucks with no device available |
| Who sees the data | The vehicle owner | The shipper who placed it | Whoever has the driver’s consent |
| Precision | High | High | Lower |
| Sensors | Depends on the installation | Can include temperature and humidity | None |
| Running effort | Low once fitted | Charging and recollection | Consent per driver; fails on SIM change |
Which to choose
- Own fleet: fixed GPS, with its feed brought into your trip records.
- Hired trucks on regular lanes: portable devices, collected and reused.
- Cold chain on hired trucks: portable devices with temperature and humidity sensors.
- No device available: consent-based SIM location rather than phone calls.
Keep one trip record
Most shippers use all three. The mistake is keeping them in three places. Whatever the source, the position should land on the same trip, with the same ETA and the same customer link. See GPS device integration.
How Portable GPS Tracker does it
Portable GPS Tracker is built for shippers that hire most of their fleet. A charged 4G device (with 2G fallback on highways) is assigned to the trip at the gate, and the trip is created in about forty seconds from masters: vehicle, carrier, LRs, invoices, route and driver. The customer gets a live tracking link with no app and no login, which expires when the trip closes. Every ping carries position, battery, temperature and humidity; ETA is worked out from remaining kilometres and the speed this truck actually makes; excursions, long halts and silent devices are flagged to the desk. At arrival the trip closes, a movement report is ready in PDF or Excel, and the device is queued for collection and back into the branch inventory. Where there is no device, consent-based SIM location is the fallback, and fixed GPS and carrier telematics feeds can land on the same trip.
Questions
Is a portable GPS better than a fixed GPS?
For your own fleet, fixed GPS is simpler. For hired and market trucks that change every day, a portable device that belongs to the trip is more practical.
Is SIM tracking as accurate as GPS?
No. SIM-based location is less precise and depends on the driver’s consent and SIM, so it works best as a fallback.
Can I use all three together?
Yes, as long as every source lands on the same trip record with one ETA and one customer link.
