Public bug reported:
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.

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.
