Your device is using GT06 protocol, so correct port is 5023.

Thx for the fast reply, I read other posts on this forum and I changed the port, I try with the full IMEI and with 11 digits preceded by 0 an nothing, I have a sim with credit and roaming, I seng sms to the devices an he reply but in traccar he stay in Offline.

If it doesn't work follow troubleshooting guide.

The server dont receive info from the device, because hi dont receive GPS signal, I fixed it configuring at open sky. All works fine! thx!
