# Configure Queclink GL3xx trackers

* If you don't want to spend time on tracker configuration, you can directly purchase ready-to-use units at <https://racemap.com/gps-tracker#buy>. All GPS trackers shipped with:&#x20;
  * inserted M2M SIM cards,&#x20;
  * the latest firmware and&#x20;
  * RACEMAP configuration.&#x20;
* You can also use devices you already own or purchase elsewhere, along with your own SIM cards, or with our M2M SIM cards. In that case, you configure the trackers on your own. For other tracker types than Queclink GL3xx series, consult your supplier for the commands for initial configuration. \
  [Check the list of supported devices](https://docs.racemap.com/hardware-for-live-tracking#various-gps-devices-for-live-tracking-in-racemap).

#### Configuration of your Queclink GL3xx trackers

Step-by-step playbook to configure Queclink GL3xx GPS trackers on your own.

**1. Remote configuration:** Our migration guide enables you to configure multiple devices at once with automated, scalable workflows.

{% endcontent-ref %}

**2. Local (physical) configuration:** Configure devices individually using a computer, the Queclink Manage Tool (download of local software), and the appropriate data cable.

[Configuration via cable](/gps-devices/config/cable.md)
{% endcontent-ref %}

After successful configuration, the devices are ready to establish a TCP connection with RACEMAP and you can communicate remotely through the tracker management e.g. to send commands.
