Public bug reported: I am trying to use a mobile broadband sim with my TabletPC running Ubuntu 18.04, but it doesn't work, I get: "Connection Failed: Activation of network connection failed" when trying to connect with it. HOWEVER, if I boot this same TabletPC into Windows 10, the sim works fine. So it is not a problem with the SIM nor a problem the TabletPC hardware. It is a problem with Ubuntu.
Can I ask what testing/Quality Assurance (QA) you did on Ubuntu for mobile broadband and where your testing records are kept? Further details here: https://askubuntu.com/questions/1079689/mobile-broadband-sim-doesnt-work-with-ubuntu-18-04-but-does-work-in-same-device "I have a Panasonic FZ-G1 MkIII Toughpad touchscreen tablet PC which is based on an x86-64bit Intel® Core™ i5-5300U CPU @ 2.30GHz, with 4Gb RAM. This is dual-booted with Windows 10 Pro 64bit (build 1803) and Ubuntu 18.04.1 LTS 64bit. The mobile sim is a standard giffgaff sim which works fine in Windows on this machine - it is recognised and internet access via it works, detected as LTE (4G). So this proves that the sim is working correctly with the WLAN modem hardware in this tablet. However, when the same tablet is booted into Ubuntu 18.04.1 LTS 64bit, the same sim that worked in the Windows partition, does not work in Ubuntu. Error message: "Connection Failed: Activation of network connection failed" pops up when attempting connection via Settings.
