If your device isn’t responding to SMS, please check the following:

Ensure the SIM card is properly inserted, has an active plan, and no PIN code is set.
Confirm the SMS format matches the device manual.
Test the SIM card in a phone to verify it can send and receive messages.
Check the device manual to confirm what the solid blue and yellow lights indicate.

If the issue persists, please write to us at support@gps-trace.com with the login, unit ID, screenshot of device configuration (SMS commands and device’s answers) and link to this topic, then we will try to check additionally and help you.

Based on the symptoms you’ve described, here are the recommended troubleshooting steps:

First, verify the power supply since the lights are not blinking:

Check if the device is properly connected to power
Ensure the internal battery is charged
Try disconnecting and reconnecting the power

Since you’ve already configured the basic settings and received “SET OK”, verify these critical settings:

Confirm the APN settings are correct for your SIM card provider
Ensure the time zone is set to UTC 0
Verify the server and port settings match those shown in the Hardware tab of your unit settings in our platform

For the SIM card:

Try testing the SIM card in a phone to confirm it has:

Active data service
Sufficient balance
No PIN code restriction
