4. Setup Guide

Step 2: Power On the Tracker
Charge the device for approximately 1 hour. The yellow and blue indicator lights will flash as it searches for network and GPS signals. Allow 5 minutes in an open area (near a window or outdoors) for both lights to become solid, indicating successful connection. If the yellow light continues to flash, move to a different location.
Step 3: Configure APN Settings
You need the Access Point Name (APN) details from your SIM card provider. Send an SMS command from another phone to the tracker's SIM card number to set the APN.
- If your SIM's APN has no username or password, send:
8030000<space>APN(e.g.,8030000 everywhere). The tracker will reply "SET OK". - If your SIM's APN has a username and password, send:
8030000<space>APN<space>APNuser<space>APNpass(e.g.,8030000 everywhere eesecure secure).
Note: APN settings vary by SIM card provider. Apply the correct formula based on your actual APN.
Step 4: Set GPRS Mode
Send the SMS command 7100000 to the device to set GPRS mode. Wait approximately 30 seconds. Both blue and orange lights should remain ON, indicating the tracker is active and ready for online tracking.
You can now log in to the SinoTrackPro web platform or app using your tracker's ID number (found on the product) and default password "123456". If the device shows an incorrect location (e.g., China), take it to an outdoor area with good signal to update its GPS location.
If the device is not online, send RCONF to the device to check its settings:
- 1. Verify the APN is correct.
- 2. Verify the IP and Port match the user manual.
- 3. Confirm the device is in GPRS working mode.
