Reusing a Queclink GB100 tracker with personal SIM?

BitKid 20 days ago

Hi everyone,
I'm trying to repurpose a 2-year-old Queclink GB100 GPS tracker that was previously tied to a fleet subscription.
I removed the PIN code from a personal SIM card and inserted it, but the red, blue, and green LEDs just flash rapidly (about once a second). It seems stuck searching for a network and won't connect.
I could really use some advice on a few things:
Network connection: How do I get it to connect to the GSM network? Could it be network-locked, or does it just need the correct APN settings?
SMS Configuration: I know these are configured via SMS commands, but since it's not getting online, I can't reach it. Is there a way to bypass or reset the password/configuration?
Hardware pins: There are 7 pins on the back (* * * * / * * *). Is this a serial/UART interface that I can use for direct configuration via cable?
How do I move on from here? Any insights or command guides for the GB100 would be awesome.
Thanks in advance!

I'd suggest you start with a Google search https://www.google.com/search?q=queclink+gb100+gps+sms+configuration+guide

then download and read the User Manual https://fcc.report/FCC-ID/YQD-GB100MG/4716669.pdf

A local sim should receive the SMS commands detailed in the Google search.

Follow Anton's post about identifying the protocol used

Hi i'm Thank you for young time to answer me, i'm so sorry but I cannot find anything about how to configure the GPS to send the data elsewhere.

I did found out how to get it online with my own SIM card, yet I don't know how to configurate to send the data to where I wanted to be sent.

The manuals did not give any hints about that, if you know anything could you please send me in a Direction then I would be really happy

Format the SMS commands exactly as shown below, replacing the placeholder values (e.g., 123456) with your specific device password and data. Note: Commands should be sent as separate, standalone text messages.1. Set the APN & Server ParametersSend the following AT command to configure your network and backend server:AT+GTQSS=123456,APN,APN_Username,APN_Password,4,,0,Server_IP,Port,192.0.0.0,0,,0,0,,,FFFF$123456: Default device password (change if yours is different).APN: Your network's APN.Server_IP: Your tracking platform's IP address.Port: Your tracking platform's port.2. Configure Reporting IntervalsSend this command to set how often the device reports its location (e.g., every 30 seconds):AT+GTFRI=123456,1,0,,,0000,2359,30,30,30,30,1F,1000,1000,0,7,50,5,,,FFFF$3. Reboot the DeviceOnce configured, restart the device to apply changes:AT+GTRTO=gv500,3,,,,,,FFFF$ (or refer to your specific firmware for the reboot command)Step 3: Verify and TroubleshootOnce the device reboots, it will connect to your server.Check the device status by sending: AT+GTRTO=gv500,14,,,,,,FFFF$For bulk configurations or complex parameters, it is highly recommended to use the manufacturer's Queclink Manage Tool with a USB data cable instead of SMS.Refer to the official Queclink GB100 Series Guide for the complete AT command reference and protocol details.
