Since trackers of different manufacturers and models work according to different protocols, it is difficult to say for sure whether your tracker corresponds to one of the protocols we support.
We cannot guarantee that it will work but you can try to identify your tracker on id.wialon.net as one of the devices Sinotrack ST-901, ST 902, Gosafe G91I, Rilla G19.
If your tracker is determined, take a screenshot, write down the name of the model of the tracker and the identified ID (may coincide with the IMEI, may be part of it with zero or without).
After that, return to the application in the unit settings (unit menu - Settings - Common Settings), specify the determined model and ID. After that, configure the tracker on the defined server and port.
