Hello, AllovitalikVitalik ,
As we checked, your device did not even attempt to connect the device and, accordingly, did not send messages.
You can see this for yourself in the unit’s Toolbox. – https://help.gurtam.space/en/article/tools
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.
3) APN settings(should be checked with mobile provider)
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.
If you can’t find the problem, send us a screenshot of the device configuration(SMS commands and device’s answer) and link to this forum topic, we’ll try to check it additionally.
