mitya94 Hello!
Try to identify your tracker on id.wialon.net
You can try the types of devices Xexun, Coban, Concox, as well as YuLongDa GT06, Secumore G200, Xeelectech LK206, Xeelectech LK210, Rilla G19
If your tracker is determined, remember the type of device and id
An id can be the device IMEI or its part with the addition of zero or without.
If the tracker is determined, then the unit in the application must be configured taking into account the determined type and ID of the device. Then, if necessary, reconfigure the port and server of the device.
