Step 1: Install USB packages
{{{
kmod-usb-net-cdc-ether 
kmod-usb-net-qmi-wwan 
kmod-usb-net-rndis 
kmod-usb-serial 
kmod-usb-serial-option
kmod-usb-serial-wwan 
kmod-usb-wdm 
usb-modeswitch
}}}
Install LTE-4G packages
{{{
luci-proto-qmi
uqmi 
}}}


Step 2: Create the QMI interface
Go to Network => Interfaces => click "Add new interface"
You can input any name you like. In this example, I named my interface "4G". 
In the protocol field choose "QMI". If you don't see QMI on the list, you have not installed the right packages or haven't rebooted the router.

Step 3: Get signal info status
{{{
#!sh
root@OpenWrt:~# uqmi -d /dev/cdc-wdm0 --get-signal-info
{
        "type": "lte",
        "rssi": -68,
        "rsrq": -14,
        "rsrp": -100,
        "snr": 2.000000
}
root@OpenWrt:~# uqmi -d /dev/cdc-wdm0 --get-data-status
"connected"
root@OpenWrt:~# uqmi -d /dev/cdc-wdm0 --get-current-settings

        },
