Hello, DmitriyRumyantsev ,
As we checked your unit there was no problems with it.
At this point, the device just stopped sending data to the system.
In this case, first of all, check on the tracker side:
1) SIM card balance and traffic limits on it
2) Data sending intervals and tracker operation mode
The tracker may have entered sleep mode or some settings have gone wrong.
It is best to contact the device manufacturer or dealer for the tracker settings.
Also, information on settings can be found in the instructions for the device.
For information, we added Sinotrack devices to the Hardware category some time ago. Including ST-901.
Now you can change the category and type of device in the Common settings of your unit. More functionality will become available to you.
When changing the device type, be sure to configure the device for the new server and port.
If you can’t find the problem, write us to firstname.lastname@example.org specifying login, unit ID and a screenshot of the device configuration, we’ll try to check it additionally.
