mmcli -L
/org/freedesktop/ModemManager1/Modem/0 [QUALCOMM INCORPORATED] SIMCOM_SIM7600G-H
sudo mmcli -m 0 - e
sudo nmcli c add type gsm ifname cdc-wdm0 con-name 4GNet apn yourapn gsm.username gsmusername gsm.password gsmpassword
replace yourapn and gsmusername with your carrier service
then we can see a 4GNet in NetworkManager (like KDE's network manager UI)
I got the cdc-wdm0 from with qmi_wwan driver
mmcli -m 0 | grep "primary port"
it will be ttyUSB2 if use qcdm driver
Now we can use nmtui to connect 4GNet
or
sudo nmcli connection up 4GNet
sudo nmcli connection down 4GNet
if everything is right ,you will have your ppp0 in sudo ifconfig
Here is reference arguments I've used for nmcli

if nmcli can not start the gsm connection with errors like Ipv4 stack ,dual-stack addressing not supported by the modem
that means we need to re-compile the kernel
requires all ppp driver in kernel
Devices drivers ->Network device support
and compile as *, not module
Linux Kernel Configuration
└─> Device Drivers
└─> USB support
└─> USB Wireless Device Management support
as module
Linux Kernel Configuration
└─> Device Drivers
└─> Network device support
└─> USB Network Adapters
└─> QMI WWAN driver for Qualcomm MSM based 3G and LTE modems
as module
on A06
sudo apt install pppoe
we have to blacklist some kernel modules
$ cat /etc/modprobe.d/blacklist-qmi.conf
blacklist qmi_wwan
blacklist cdc_wdm
