Setup
Follow these steps to set up your Safire SF-MIFI-4G-UPS router:
- Insert SIM Card: Locate the SIM card slot (usually under a cover or battery). Insert your activated 4G SIM card into the slot, ensuring it is correctly oriented.

- Connect Devices (Wi-Fi): On your Wi-Fi enabled device (smartphone, laptop, etc.), search for available Wi-Fi networks. Select the network name (SSID) broadcast by your Safire router (e.g., "Safire_XXXX"). Enter the default Wi-Fi password (usually found on a sticker inside the battery compartment or on the device itself).
- Connect Devices (Ethernet): For wired connections, connect an Ethernet cable from the router's RJ45 port to the Ethernet port on your computer or other network device.
Operating Instructions
Connecting to the Internet
- Wi-Fi Connection: Once powered on and connected to 4G, the router will broadcast its Wi-Fi network. Connect your devices using the SSID and password.
- Ethernet Connection: Devices connected via the RJ45 port will automatically obtain an IP address and access the internet once the router has an active 4G connection.
Accessing the Web Management Interface
To configure advanced settings, you can access the router's web management interface:
- Ensure your device is connected to the router via Wi-Fi or Ethernet.
