Since trackers work with different manufacturers and models according to different protocols, it is difficult to say for sure whether your tracker corresponds to one of the protocols we support.
Please try to identify your tracker on id.wialon.net as one of the devices ES-GP06, Wonlex Waterproof kids watch, Wonlex mini tracker S04, Gosafe G1C, Gosafe G91I, Rilla G19, RC mini, Easytrac mini, GlobusGPS GL-TR1 mini, M2M-Mini, Gryphon MINI
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 no)
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.
If none of these types is suitable, then please try to check with the seller or manufacturer on the basis of which protocol the tracker transmits data.
