I'm running Ubuntu on my Thinkpad x230 equipped with a mobile broadband card:
Bus 003 Device 025: ID 0bdb:1926 Ericsson Business Mobile Networks BV
This used to work seamlessly in Ubuntu 13.10 (and previous ones). After upgrading to Trusty, upon login, after resume I always get a dialog asking for the PIN of the SIM card. Marking "remember PIN" while answering doesn't help - the same dialog appears again upon next login or resume.
Any hints how to get rid of that dialog and remember the PIN? I'm aware that I can switch off PIN usage on the SIM itself, but I'd prefer a solution where the PIN is remembered.
Addendum based on comments below
I have a broandband connection configured containing the PIN as well. The connection works perfectly fine. The issue is that the PIN dialog pops up upon login and resume even if WWAN connection is not activated. Default connection is ethernet or Wifi. As a side information: I'm using TLP - but I doubt that this is related to the issue.
