First, congrats on buying a GPS tracker. They are incredible devices.
To get started, first make sure your tracker is completely charged and powered on.
It may take a moment for your tracker to connect to the cell network and get a GPS fix for the first time.
You will want to download the tracking app for your smartphone (or you can use the web tracking app, gps.logistimatics.com). For some trackers, there are additional features available only in the mobile app.
You can log in with the e-mail address and password you chose when you purchased or activated your tracker.
Once your tracker is powered on, it should update the map view and display it's current position. In order to access the Live audio features, you will need to set your cell phone as the authorized number. Here's a video explaining how to do this.
