GPS tracker for trailers
Wireless, battery-powered tracking for dropped trailers, chassis, and any asset without power. No wiring, no installer — stick it on and see it on the map.
Why trailers need a battery-powered tracker
A tractor has constant 12–30V power, so a hardwired tracker works fine. A trailer doesn't. It gets dropped in a yard, at a customer dock, or at a truck stop — sometimes for weeks — with no power on board. That's exactly when you most need to know where it is: unattended trailers are what get stolen, misplaced, and forgotten.
The TP057 is built for that reality. It carries its own power, reports over LTE-M whether or not a tractor is attached, and its covert, magnetic mounting means a thief has no wiring to cut.

TP057 vs a hardwired tracker
If the asset has its own power — a tractor, straight truck, or van — the hardwired TP056 is the better fit: it never needs charging and includes a backup battery for when power is cut. For anything unpowered, the TP057 is the right tool. Many fleets run both: TP056 in the cab, TP057 on every trailer. See the side-by-side comparison.
Frequently asked questions
Does a trailer GPS tracker need to be wired in?
No. The TP057 is fully wireless — it runs on an internal 2200 mAh battery and mounts magnetically, so it works on dropped trailers, chassis, and other assets with no power source. No installer or wiring is needed.
How long does the battery last?
The internal 2200 mAh battery keeps reporting for months on unpowered trailers. Actual life depends on how frequently the device is configured to report — less frequent check-ins stretch the battery further.
How much does trailer GPS tracking cost?
$249 USD covers the hardware and a full year of tracking service. After the first year it renews at $19.99/mo. No contracts — cancel any time and keep the hardware.
Does it work in both the US and Canada?
Yes. The TP057 uses LTE-M, a purpose-built IoT cellular network with coverage across the United States and Canada, including deep rural reach. The hardware is FCC and IC certified.
