1. Debugging Plugzio Devices
The first thing to check is the LED light on your Plugzio device. The LED color tells you the current mode and status.
1.2. Reboot and Check Device Power
Ensure the breaker is turned on.
Try resetting the breaker.
Confirm the device is installed correctly and receiving power, and ensure the LED light on the device is illuminated (ask an electrician if unsure).
If the LED remains off, the device may be defective → please request an RMA.
2. Cellular Connectivity
2.1 Verify 4G Signal Strength
Use a phone at the installation site to check for LTE/4G signal (not 2G/3G/5G).
Place the phone close to the Plugzio device or modem.
Ensure at least 3 bars of LTE signal (4 is ideal).
Refer to this article for detailed signal requirements.
If the signal is weak, consider relocating the modem or using a cellular booster.

Ensure the SIM card is inserted properly.
Verify the power supply is working.
3.3 Reboot the Modem
Unplug the Ethernet cable from the modem.
Wait a few seconds.
Reconnect the cable.

3.4 Verify Internet Connectivity
Request the Wi-Fi password for the Plugzio network from Plugzio technical support.
Disable mobile data on your phone.
Connect to the Plugzio Wi-Fi network.
Try opening a webpage (e.g., google.com).
If the internet works → Network is functioning; issue may be with signal strength or the device.
If the internet does not work → SIM card or modem configuration issue.
3.5 Remote Reconfiguration
If the steps above fail, contact Plugzio Support for remote reconfiguration of the modem.
Connect the modem to a working internet source.
Ensure antennas are attached.
Provide a photo of the SIM card label and modem setup to Plugzio Support for remote assistance.
