Hello, AlexisQuino ,
First of all, it is important to understand that our system works on the basis of the data that your tracker sends in messages. If earlier your tracker on the platform worked correctly, then you should immediately check the following things on the side of the tracker:
1) SIM card balance and traffic limits on it;
2) Tracker operation mode and data sending intervals.
Perhaps the tracker went to sleep, for example, due to lack of movement.
If you cannot find the problem, please write to us at support@gps-trace.com indicating the login, unit ID and device type, then we can check your issue additionally.
Information on setting up the tracker can be found in the instructions for the device. Also, if possible, it is best to contact the manufacturer or seller of the device directly, only they can give full advice on this issue.
