Setup Guide
- Prepare SIM Card: Ensure your SIM card is compatible with the router's supported network bands. If your SIM card has a PIN code enabled, it is recommended to disable it using a mobile phone before inserting it into the router to avoid connectivity issues.
- Insert SIM Card: Locate the SIM card slot on the router. Gently insert the SIM card into the slot until it clicks into place. Ensure the SIM card is oriented correctly as indicated on the device.
- Connect Power: Connect the provided power adapter to the router's power input port and then plug it into a standard electrical outlet. The router will power on automatically.
- Initial Boot-up: Wait for the router to boot up. The indicator lights on the front panel will illuminate, indicating power, network signal, and Wi-Fi status. This process may take a few minutes.
- Configure APN Settings (if necessary): In some cases, you may need to manually configure the Access Point Name (APN) settings for your mobile network provider. Refer to your mobile network provider's documentation for the correct APN settings. You can usually access the router's web interface by connecting a device to its Wi-Fi network (default SSID and password are often found on a sticker on the router) and navigating to the default gateway IP address (e.g., 192.168.1.1) in a web browser.

Operating Instructions
Connecting Devices
- Wi-Fi Connection:
Locate the Wi-Fi network name (SSID) and password printed on a sticker on the bottom or back of your router. On your device (smartphone, laptop, tablet), search for available Wi-Fi networks, select your router's SSID, and enter the password to connect. The router supports up to 32 users simultaneously.
- Wired (LAN) Connection:
Use an Ethernet cable to connect your computer or other network-enabled device to one of the LAN ports on the back of the router. This provides a stable wired connection.

Troubleshooting
No Internet Connection
- Check SIM Card: Ensure the SIM card is correctly inserted and activated with your mobile network provider. Verify that the SIM card does not have a PIN code enabled. If it does, disable it using a mobile phone.
- APN Settings: Confirm that the Access Point Name (APN) settings are correctly configured in the router's web interface. These settings are specific to your mobile network provider.
- Signal Strength: Check the signal indicator lights on the router. If the signal is weak or absent, try relocating the router to an area with better cellular reception.
- Restart Router: Power off the router, wait for 10 seconds, and then power it back on. This can resolve temporary network issues.
Slow Internet Speed
- Device Count: While the router supports up to 32 users, performance may degrade with a very high number of simultaneous connections or heavy data usage.
- Signal Interference: Ensure the router is not placed near devices that emit strong electromagnetic interference (e.g., microwaves, cordless phones).
- Antenna Position: Adjust the position of the high-gain antennas to optimize signal reception.
Wi-Fi Disconnections
- Distance from Router: Ensure your devices are within the router's Wi-Fi coverage area (up to 200m).
- Obstructions: Walls, floors, and other physical obstructions can weaken the Wi-Fi signal.
- Channel Interference: If you experience frequent disconnections, try changing the Wi-Fi channel in the router's settings to avoid interference from neighboring networks.
