  If you are unable to access the internet using your TCL Network Router: * If no SIM card is detected, power off your CPE, and reinstall the SIM card, then try again. * If a PIN code is required, enter the PIN code, and try again. * If no network is available, place the CPE in an area with a better signal (for example near a window), and try again. * Reboot your CPE by pressing the power button for 10 seconds, and try again. * If the MAC filter function is enabled, make sure your device's MAC address is not blocked in the MAC filter settings.

  If your TCL Network Router displays 'PIN lock' or 'PUK lock', this means the SIM card is locked. To unlock it, log in to the web UI and enter the PIN code or PUK code. Contact your internet service provider to obtain the PUK code. Note: If you enter the PIN code incorrectly 3 times, you'll need the PUK code. If you enter the PUK code incorrectly 10 times, the SIM card will be permanently locked.
