According to your tracker’s manual, you are trying to send a request to determine the tracker’s location.
If the tracker does not respond to the location request command via SMS, but responds to other commands, the possible reasons may be the following:
Incorrect command format - Make sure the command is sent in the correct format supported by the tracker.
Network restrictions - Sometimes operators may block certain types of SMS or commands. Check the terms of the operator.
Tracker settings - The tracker may have the function of sending coordinates on request disabled or require additional settings.
Request limit exceeded - Some trackers have restrictions on the frequency of sending data on request.
Check these factors and, if the problem persists, consult the device documentation or contact the tracker supplier.
