Title:
  NM tries to activate GPRS context of non-present SIM

Status in network-manager package in Ubuntu:
  Expired

Bug description:
  If a device has had more than one SIM installed, the filesystem will
  include ofono-specific directories for each of these SIMs.

  When NetworkManager walks through the list of possible GPRS contexts (
  aka APNs ), it currently doesn't apply any logic to filter non-present
  SIMs.

  Here's a filtered set of NetworkManager messages that shows activation
  attempts after boot, you'll notice that NM tries to activate two
  different "context1"s, one for each SIM that'd been detected and read
  by ofono.

  Here's the output from "nmcli c l":

  In a dual-SIM situation, this will mean that NM may try activate
  connections from both SIM on each modem.

  I'm marking this as "high", as there's a good chance that this could
  cause problems in the future that aren't easily corrected by a user.

  NM should only try and activate GPRS contexts for the SIM for which
  they've been provisioned.

  This was reproduced on mako running rtm image #26,
