The Track Box has an internal storage of 30,000 (Passive) or 10,000 (Active) detections and will send data to our servers once cellular coverage has returned. There is no option, other than via GSM upload, to extract data. Once the box has been switched off (either manually or due to a depleted battery) it will clear the storage and data that hasn't been uploaded will be lost.
How can I get data off Track Box after loss of cellular signal
