are you using MBPL USB driver?  
If yes, you can follow this:

> Here is an example to establish data connection by AT!SCACT via MBPL R20 driver: Module: WP7609 FW: R13 MBPL: R20 PC Environment: Ubuntu 18 need to install the MBPL R20 driver for qmi\_wwan and qcserial (MBPL\_Drivers\_USB\_R20\_ENG1-src.tar.gz) avoid the Ubuntu changing the network name: ln -s /dev/null /etc/systemd/network/99-default.link sudo apt-get install libqmi-utils sudo apt-get install udhcpc now insert the USB to PC sudo chmod 777 /sys/class/net/wwan0/qmi/raw\_ip …

Another option is to use MBIM interface by AT!USBCOMP=1,3,1009
