Our current implementation of SIM selection for mobile data is currently ( as of RTM #94 ) non-deterministic.
If two SIMs are installed in the phone at first boot ofono will self-power the ConnectionManager interfaces for both modems which results in the 'Powered' property of both being set to 'true'. Only one of the two will attach to the network however, and if both SIMs are unlocked, this is usually the second slot.
The cellular system settings uses the 'Powered' property to choose which SIM is selected, so the current behavior is clearly broken.
It was suggested that we should change ofono to not self-power it's ConnectionManager interface, and instead add a wizard page that allows the user to choose which SIM to use for mobile data.
