1.Identifying the wwan interface is managed or not.
root@apalis-imx6:~# nmcli d

eth1: connected to Wired connection 1
"Microchip LAN7500"
ethernet (smsc75xx), 00:1E:C0:E0:89:FD, hw, mtu 1500

eth2: unavailable

ethernet (smsc95xx), 00:1E:C0:E1:09:7D, hw, mtu 1500
wwan0: unavailable
"Quectel EC25"
wwan (qmi_wwan), CA:94:10:9D:E4:CA, plugin missing, hw, mtu 1500
2.As you can see wwan0 is showing as unmanaged and plug-in is missing,so i have run a
command("nmcli dev set wwan0 managed yes") to set as managed one.
3.Now wwan interface is showing as unavailable.
