Our Take
The SinoTrack ST-907L is a compact hardwired vehicle GPS tracker that provides real-time location, route history playback and a relay to remotely cut and restore the engine. It connects to a local SIM (not included) and reports to SinoTrackPro’s web/app platform without a monthly subscription.
This unit is aimed at riders and small-fleet owners who want an inexpensive, maintainable tracker they control — with live tracking, geofence and overspeed alerts. The main trade-off is that it relies on a user-provided SIM and text-command configuration, and its tiny 50mAh internal battery is only for short-term backup, so it’s intended to be wired to the vehicle’s power.
If you want a low-cost tracker with relay control and no recurring platform fees and don’t mind hands-on setup (APN, SMS commands, wiring), the ST-907L is worth considering. If you need plug-and-play with bundled SIM/support, this model will require extra setup and local SIM management.

- No explicit warranty or support terms provided in product facts
Scoring Breakdown
How It Performs
Design & Build Quality
The ST-907L is intentionally small and light (20 g, roughly 1.2×1.2×2.24 in). It’s a hardwired module with built-in GSM/LTE and GPS antennas. The supplied operating and storage temperature ranges are broad (-20°C to 55°C operating), which suits a wide range of climates for vehicle installation. The listing does not provide housing material or IP/waterproof rating.
Comfort & Fit
Not applicable as a wearable—fit here refers to installation. Its compact size makes it easy to hide under panels or in wiring looms. A proper, secure hardwire installation is recommended because the internal 50mAh battery is only for short-term backup.
Performance
SinoTrack specifies a GPS module (MTK2503) with positioning accuracy up to 10 meters and warm/hot start times in seconds. The device supports LTE and can fall back to 2G, which helps maintain connectivity in variable networks. Real-time updates are available via the provider platform and can be refreshed every 60 seconds when online.
Features
Key functions listed include real-time tracking, route history playback, geofence and overspeed alarms, power-off/low-battery alerts and SMS location retrieval when offline. It also includes a relay for remotely cutting and restoring the engine via SMS commands. Platform features include two years of history and the ability to group multiple devices into one account.
Ease of Use
Basic operation requires inserting an activated SIM (remove PIN), setting the correct APN via SMS commands, and enabling GPRS mode (also via SMS). The manual provides example SMS syntax and troubleshooting steps. Riders comfortable sending SMS commands and editing APN/IP settings will find it manageable; less-technical users may need help from an installer.
Battery Life
The unit includes a 3.7V 50mAh internal battery intended for backup only — the product repeatedly notes it should be connected to vehicle power. No run-time duration is provided for the backup battery; verify expected backup time with the manufacturer or your installer if continuous off-battery operation is a requirement.
Durability
Operating and storage temperature ranges and non-condensing humidity specs are provided, which indicate it’s designed for vehicle environments. The listing does not include IP or shock ratings, so for exposed mounting locations (under-seat or tail sections) choose a protected installation and confirm long-term weather resistance with the seller.
Value for Money
At the stated price and with a no-subscription platform, the ST-907L offers strong value for riders who can source a local SIM and do or pay for a hardwire install. The small form factor and relay capability add utility that’s uncommon at this price point. The trade-off is the hands-on setup and extra SIM/data costs.
Real-World Use
Use cases include covert theft prevention (engine cut/recover), tracking a motorcycle or car’s daily routes, geofence alerts for monitoring young riders, and fleet monitoring via grouped accounts. Remember the engine-cut command functions only below roughly 20 km/h, so it’s not intended to safely stop a vehicle at speed.
Comparison With Competitors
The ST-907L’s strongest practical difference is the advertised lack of platform subscription — once you manage the SIM and setup, ongoing platform access is included. Riders who prefer a bundled SIM, managed service, or turnkey installation may find other products that include those services more convenient, but typically at higher recurring or up-front costs.
Fit & Suitability
Who Is This Product For?
Who Should Buy It
Buy this if you want a low-cost, hidden hardwired tracker with relay control, you can install or have it installed, and you’re comfortable configuring APN and SMS commands and managing a local SIM/data plan.
Who Should Consider Alternatives
Avoid this model if you need a plug-and-play tracker with bundled SIM/support, if you require an explicitly specified waterproof IP rating, or if you rely on the tracker’s battery for extended off-vehicle operation — the internal battery is minimal.
Common Questions
Frequently Asked Questions
Does the tracker come with a SIM card or monthly subscription?
No. The product does not include a SIM card. You must purchase and activate a local SIM with SMS and data. The SinotrackPro platform is advertised as available without additional subscription fees, but you’ll still pay for the SIM/data plan.
Can the device remotely cut the engine?
Yes. The ST-907L includes a relay function controlled by SMS command (example given as "9400000") to cut or recover the engine. The product notes the engine cut works when the vehicle is moving below approximately 20 km/h and will not stop the vehicle safely at higher speeds.
How long will the internal battery last if the device is not wired?
The tracker has a built-in 3.7V 50mAh backup battery intended only for short-term backup. No continuous run-time duration is provided in the product facts — for expected backup endurance verify with the manufacturer or your installer and plan to hardwire the unit for regular use.
What network does it require?
The ST-907L supports LTE-FDD bands (B1/B2/B3/B4/B5/B7/B8/B28/B66) and GSM 850/900/1800/1900MHz. It can use 4G and will fall back to 2G where necessary, but you must buy a SIM that supports the required bands and ensure the local carrier’s network is available.
Is setup difficult?
Setup requires SMS configuration (APN, GPRS mode) and connecting to vehicle power. The manual provides step-by-step SMS commands and troubleshooting tips. If you’re not comfortable with APN settings or hardwiring, professional installation is recommended.
RiderInstinct Verdict
Final Verdict
The SinoTrack ST-907L is a practical budget tracker for riders and small fleet managers who want hands-on control: live tracking, geofences, two years of history on the platform and a relay for remote engine control. Its small size and no-monthly-fee platform are genuine strengths. The device does require a local SIM, SMS/APN setup and a proper hardwire install, and its tiny 50mAh battery is only for backup. If you accept those trade-offs it’s a compelling low-cost option; if you want a fully managed, out-of-the-box solution you’ll need to consider other offerings.
