I'm finding mixed results from a couple of different factory unlocked phones on both carriers. I'm not sure there's anything conclusive across USA right now.
The factory unlocked device support variables seem to be affected by:
1) T-Mobile/Sprint merger and BYOD policies of that merger regarding various Enhanced Calling Features and Network Prioritization internal rules and external regulations.
2) Specific OEM and further specific device model regarding sales volume or something likewise.
