I discovered today that the user's choice of SIM slot (configured in the messaging app) is only used for SMS. This setting gets ignored for MMS, and instead it uses whatever system settings / cellular has configured for cell data. This can cause failure to send MMS, if the other slot has no service, or can cause the message to be sent from the wrong number.

I saw this in krillin ubuntu-touch/ubuntu-rtm/14.09-factory-proposed image 10, the OTA4 candidate.

I'm not sure how feasible it is to configure this in the same manner as SMS uses, since the phone generally only connects to one cell data provider at a time, but it would be nice if it used the same policies as SMS.
