Title:
Notification should indicate if GSM modem does not have a SIM --
Huawei E172s-1
Status in “network-manager” package in Ubuntu:
Invalid
Bug description:
I have a Huawei E173s-1 (12d1:1c05) plugged in. Detection, switching, setup
all work fine out-of-the-box.
However when I went to connect all I got was a notification saying the
modem was disconnected.
The only thing I could see in the logs was "GSM modem enable failed:
(32) Failed to find a usable modem character set" which wasn't
enlightening.
Plugging in the device into a different OS, I get a window that says
"SIM not available", this prompts me to open up the device to see I'd
inserted the SIM back-to-front.
Retrospective expectation for Ubuntu network manager is that the UI
notification should say something like "SIM not found" rather than
"disconnected".
