But I already tried all indicate ports (5001, 5002, 5006, 5013, 5023, 5036, 5093) and device continue do not working

How I discover the correct port. I am using server in windows solution

thank you for all helps

Correct port for your device is 5002. Device id is 087072976438. The problem seems to be that your tracker doesn't send any location data.

Thank you for fast answer.

How you know, looking the log, that os 5002 (good know-how, by the way...)?

I sent the command "time zone123456 3" and GPS do not inform more the position . I looking for How correctamente this in Google :-(
