1 What Is the Concox OB22 OBD With Voice?
The Concox OB22 (manufactured by Jimi IoT, formerly Concox) is a plug-and-play OBD-II GPS tracker that connects directly to your vehicle's OBD-II diagnostic port — the same port mechanics use for car diagnostics. Once plugged in, it draws power directly from the car, requires no wiring, and begins transmitting real-time location data to a smartphone app or web platform immediately.
What sets the OB22 apart from basic OBD trackers is its built-in microphone for remote voice monitoring. This allows an authorized user — a fleet manager, car owner, or parent — to silently listen to conversations and sounds inside the vehicle by sending a simple SMS command to the device. No one inside the vehicle is alerted.
2 Key Features of the Concox OB22
Remote Voice Monitoring
Listen to audio inside the vehicle remotely using an SMS command. No sound or light is emitted — the monitoring is completely silent and undetectable by the driver.
Real-Time GPS Tracking
Live location updates transmitted via GSM/GPRS to the tracking platform. Accuracy under 10 meters via GPS; under 500 meters via LBS fallback in GPS-weak zones.
Plug & Play OBD-II
No professional installation required. Locate the OBD-II port (under the dashboard, driver's side), plug in the device, insert a SIM card — done. Works in 5 minutes.
Plug-Out Alarm
If someone unplugs the OB22 from the OBD port, an instant alert is sent to your phone. This prevents tampering and device theft by unauthorized persons.
Driver Behavior Analysis
Detects and logs harsh acceleration, sudden braking, sharp cornering, and overspeeding. Generates driver score reports for fleet managers and insurance purposes.
Ignition Status Detection
Real-time engine on/off status based on battery voltage monitoring. Get notified the moment your vehicle's engine starts or stops — even when you're not nearby.
Geofencing Alerts
Draw virtual boundaries on the map. Receive instant alerts when the vehicle enters or exits these zones — perfect for school zones, warehouses, or city limits.
Silent Operation
The OB22 triggers alarms and transmits data without emitting any sound or light. Drivers remain unaware the device is active — ideal for covert fleet monitoring.
Trip History Playback
Review daily, weekly, and monthly route history on the platform. See exact paths taken, stops made, speed at each point, and total distance traveled.

3 How Voice Monitoring Works — Step by Step
🎙️ Remote Voice Monitoring — The OB22's Star Feature
The Concox OB22 contains a built-in microphone that can be activated remotely via SMS. Once triggered, the device silently calls back your phone, allowing you to hear everything inside the vehicle — without any indicator light or sound alerting the driver.
- Insert a local SIM card (Grameenphone, Robi, Banglalink) into the OB22's SIM slot and ensure it has an active data plan and can receive/make calls.
- Configure the device's authorized phone numbers via the app or SMS commands during initial setup.
- To activate voice monitoring: send a specific SMS command (provided in the user manual) to the OB22's SIM number from your registered phone.
- The device receives the command and silently calls back your phone — NO ringtone, NO LED flash inside the vehicle.
- Your phone connects and you can hear all audio inside the car clearly through the built-in microphone for the duration configured (usually 30–120 seconds).

5 How to Install the Concox OB22
One of the OB22's greatest strengths is its zero-hassle installation. No mechanic, no tools, no wiring. Here's the complete step-by-step process:
Insert an Activated SIM Card
Before plugging in the device, insert a local SIM card (Grameenphone, Robi, Banglalink, or any carrier) into the SIM slot on the OB22. Make sure the SIM has an active data plan and is able to make and receive calls (for voice monitoring). Recommended: a data-only SIM with at least 50MB/month.
Locate Your OBD-II Port
The OBD-II port is a 16-pin trapezoid-shaped socket found under the dashboard on the driver's side — usually within 60cm of the steering wheel. It may be covered by a small plastic flap. All passenger cars manufactured after 1996 (gasoline) and 2004 (diesel) have this port.
Plug In the OB22
Firmly insert the Concox OB22 into the OBD-II port until it clicks. The device draws power directly from the port — no batteries, no external wiring. You may see a brief LED flash during boot-up (usually within 30 seconds of plugging in).
Download the Tracking App
Download the Tracksoild app (or the platform app provided by your reseller in Bangladesh) from Google Play or the App Store. Create an account using your phone number and email. Log in to the dashboard.
Add the Device to Your Account
In the app, select "Add Device" and enter the OB22's IMEI number (printed on the device label or packaging). The device will appear on the map within 1–3 minutes once it acquires a GPS signal. Turn on your car's ignition to speed up the first satellite lock.
Configure Alerts & Voice Monitoring
Set your geofence zones, speed alert thresholds (e.g., 80 km/h), and configure authorized phone numbers for voice monitoring. Test voice monitoring by sending the SMS command (from the manual) to your device's SIM number and confirming the callback works.

9 Who Should Buy the Concox OB22?
✅ Perfect For:
- Hybrid & brand-new car owners in Bangladesh — best solution for protecting new vehicles without drilling holes or permanent wiring
- Fleet operators — monitor driver behavior, fuel efficiency, and unauthorized vehicle use across multiple vehicles
- Ride-share and taxi companies — track CNG, Uber, and Pathao vehicles; listen to driver-passenger interactions for safety
- Car rental businesses — ensure rented vehicles stay within agreed zones; get plug-out alerts if trackers are removed
- Parents monitoring teen drivers — receive overspeed alerts and check route history after trips
- Business owners with company vehicles — confirm vehicles are being used only for work purposes during business hours
❌ Not Ideal For:
- Motorcycles or bicycles — OBD-II ports are car-specific; use a hardwired tracker instead
- Vehicles pre-1996 — older cars may not have OBD-II ports
- Covert vehicle tracking (non-owned vehicles) — illegal and unethical; see legal note above
- Users needing 4G LTE speed — the OB22 runs on GSM/GPRS; for 4G tracking consider the Concox VL512

10 Frequently Asked Questions
11 Final Verdict — Is the Concox OB22 Worth Buying?
Absolutely yes — especially for buyers in Bangladesh. The Concox OB22 delivers an impressive combination of features for its price point. No other OBD GPS tracker in the same price range offers voice monitoring + plug-out alarm + silent operation + driver behavior analysis + BRTA documentation management all in one device.
Its GSM/GPRS network limitation is a minor drawback — but for everyday tracking across Bangladesh, GSM coverage is strong enough that you will rarely notice a difference. The plug-and-play installation means anyone can set it up in under 5 minutes, making it ideal for non-technical users.
For fleet operators, the combination of voice monitoring, driver behavior reports, and group management makes the OB22 a remarkably cost-effective fleet telematics solution. For personal car owners, it provides the security of knowing your vehicle is always traceable — and that you can listen in if something feels wrong.
