Hi RL, Personally, I only used SDK and driver officially from Sierra below, I never try the mmcli tool… [https://source.sierrawireless.com/resources/airprime/software/linux-qmi-sdk-software-latest/](https://source.sierrawireless.com/resources/airprime/software/linux-qmi-sdk-software-latest/) [https://source.sierrawireless.com/resources/airprime/software/usb-drivers-linux-qmi-software-s2,-d-,39n2,-d-,60/](https://source.sierrawireless.com/resources/airprime/software/usb-drivers-linux-qmi-software-s2,-d-,39n2,-d-,60/) But from your log, seems like mmcli try to start data connection from enp0s20u1i19 (cdc-ether) and failed. > $ mmcli -m 6 --simple-connect=“[apn=internet.sierrawireless.com](http://apn%3Dinternet.sierrawireless.com/)” > error: couldn’t connect the modem: ‘GDBus.Error:org.freedesktop.ModemManager1.Error.Core.NotFound: Couldn’t find associated QMI port for ‘net/enp0s20u1i19’’ Does mmcli allow you to start data connection from specific interface (i.e. wwan0 )? Or you can try disable cdc-ether interface on your WP8548 then try again (so not to confuse mmcli), i.e. ``` AT!ENTERCND="A710" AT!USBCOMP? AT!USBCOMP=1,1,10F AT!RESET ``` Hope that work, please mark down the default value (returned by AT!USBCOMP?) in case you want to restore it later. Thx ---

What ModemManager version are you using? This specific problem was fixed in commit [fd1a26fc36df005d66627109875631264d2f8e19](https://gitlab.freedesktop.org/mobile-broadband/ModemManager/commit/fd1a26fc36df005d66627109875631264d2f8e19), released with ModemManager 1.12.0 If you’re not using MM 1.12.x, you can try with this 18.04 PPA I maintain: [https://launchpad.net/~aleksander-m/+archive/ubuntu/modemmanager-bionic](https://launchpad.net/~aleksander-m/+archive/ubuntu/modemmanager-bionic) ---

My MM version was 1.10.x. With the MM version 1.12.2, all is working fine. Thank you for the help ! ---

Your solution works in 2025 - I had the same issue in Australia with MC7421 on Ubuntu Mate 18.04. I really appreciate you work .
