So nestled deep in the network-test-session log is the following error:
2014/09/26 23:07:04 Cannot Activate interface on %s: %s /ril_0/context2
org.ofono.Error.NotAttached: GPRS is not attached
So, I'm thinking this may be related to the Network Manager bug that
describes mobile data connections not always being activated when
FlightMode is toggled off. MMS only works when "mobile data" is
enabled. When mobile data is enabled, NM is responsible for toggling
the ConnectionManager's 'Powered' property, which is turn causes the
'Attached' property toggle to true. So even though in this case the MMS
context is stand-alone, if NM hasn't toggled 'Powered', GRPS will never
become attached.
On krillin, the modem initialization sequence takes longer than mako due
to the dual SIM. Of note is the fact that the ConnectionManager
interface is the last to get created, and there's a few seconds lag with
the other interfaces. It's been discussed that this lag is what causes
NM to miss setting the 'Powered' property. I will add a network-manager
task to the bug.
