7. Troubleshooting (FAQ)

Q1: Why can't the device recognize the SIM card?

A1: Please insert the SIM card into the router for one minute first, then turn on the power. If it still doesn't recognize the SIM card, try installing another SIM card from a different operator.

Q2: Why can't I use the internet when I insert a SIM card?

A2: Even if your SIM card is compatible, it may not be plug-and-play. You might need to disable the SIM card PIN and modify the APN settings.

Q3: How do I modify the APN?

A3: Enter the router's IP address (http://192.168.199.1) in a browser and navigate to 'APN Settings'. Modify the APN. You can find your SIM card's APN on your carrier's official website or by checking your mobile phone settings. Ensure the SIM card is activated.

Q4: The router cannot search for Wi-Fi?

A4: Check if the Wi-Fi indicator light is on. If it is, the Wi-Fi might be hidden. Log in to the web management interface to enable the Wi-Fi name (SSID).

Q5: The router's network speed is slow.

A5: The router needs to capture the signal and re-transmit it, which can make it slightly slower than direct phone connection. Speed can vary based on local conditions and SIM card. Try a different SIM card if possible.

Q6: Signal is unstable?

A6: You can manage the settings page to lock the router to a 4G or 3G network, which can improve network stability.

Q7: All settings are correct, but the device still cannot connect to the network?

A7: Consider the following possibilities:

• The account might be suspended due to excessive data usage.
• The SIM card might be an IoT card, which may not be fully compatible.
• The SIM card may have limited service or not be designed to work with routers/hotspots.
• The network frequency band might not be covered in your current location.
