I have the same problem, using a Huawei E173 under Ubuntu 15.10. I confirm that connections remain editable before reboot, when created through nm-applet. This works both for those created using 'Edit Connections' as for those created using the "New Mobile Broadband connection" menu item (menu item of nm-applet showing up when modem is registered, without any existing configured connections).
Two other observations: 1. When I create a new connection using "New Mobile Broadband connection", and edit it immediately afterwards, I don't see any APN configured. As the connection works, I nevertheless assume that this information is somehow available to NetworkManager. 2. System Settings -> Network -> Mobile Broadband -> Add new connection: nothing happens -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager-applet in Ubuntu. https://bugs.launchpad.net/bugs/1508718 Title: NetworkManager - error initialzing editor Status in network-manager-applet package in Ubuntu: Confirmed Bug description: Error initializing editor settings/nm-settings-connection.c.995 - Connection didn't have requested setting 'ppp' Error occurs when attempting to edit existing mobile broadband connection.
