In the case of errors in call management; those are already passed back to NetworkManager, but they get lost in there without getting to the UI probably.
And for the case of the no SIM errors, you're right, the UI may not want to spam the user with notifications about the missing SIM; but it may just show the modem item with the error string in either the NM applet or the Shell Indicator. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1113703 Title: Trying to connect using a GSM modem without SIM card is not reported to user Status in ModemManager (with NetworkManager support): Unknown Status in NetworkManager: Confirmed Status in “gnome-shell” package in Ubuntu: New Status in “modemmanager” package in Ubuntu: New Status in “network-manager” package in Ubuntu: New Status in “network-manager-applet” package in Ubuntu: New Status in “networkmanagement” package in Ubuntu: New Bug description: Trying to connect using a GSM modem that lacks a SIM card does just give the user a general connection failure message without any hints about the missing SIM card.
