Despite unity8 also being a possible culprit, I was guessing it might be
the indicator because the bug description indicated that it mattered
which sim slot was locked.  unity8 doesn't even get that information.
So I figured it was below unity8.  But if it looks like the indicator is
doing its job fine, I'll give a look at the notification code in unity8.

Title:
  SIM PIN Unlock doesn't always trigger an actual unlock action

Status in indicator-network package in Ubuntu:
  New
Status in unity8 package in Ubuntu:
  New

Bug description:
  current build number: 127
  device name: krillin
  channel: ubuntu-touch/devel-proposed

  Two SIMs installed, SIM in the second slot is PIN-locked.

  It's possible for a PIN to be entered on the SIM auto-prompt screen (
  displayed at boot ) and the subsequent action ( ie. the DBus EnterPin
  call to ofono ) to get dropped.   This results in the SIM still being
  locked when the user dismisses the greeter.

  This bug was discovered while testing an ofono vivid silo.  The
  associated ofono merge request is:

  https://code.launchpad.net/~phablet-
  team/ofono/ww10-update/+merge/250665

  The version of ofono in the silo (ubuntu-013) is:

  1.12.bzr6888+15.04.20150224-0ubuntu1

  There's some kind of race condition involved, as this seldom happens (
  ~5% of the time ).

  I was finally able to prove that this was unity8 ( or some other upper
  layer component ) by adding info log messages to the ofono functions
  that handle the DBus EnterPin method, and the associated callback
  function.  The scenario that clinched it for me was:

  1. Boot phone

  2. Enter bad PIN and tap check button when prompted for SIM2
  [ See that remaining Retries is reported as 2 ]

  3. Enter PIN again and tap check button again

  4. Examine syslog and notice that there's only a single call to
  EnterPIN, which is followed by a log message showing the callback
  failure for the bad PIN entered.
