That is really not how it works. If the file ID is the same then you
need some other information to determine whether this is a phase 3 or a
phase 2 SIM. Look at how EFecc reading in voicecall.c is done. In
other words, this function needs to make an intelligent decision whether
this is EFsst or EFust.
In your case the only heuristic we have is EFphase, which is mandatory
for all Phase 2 SIMs (and absent in all Phase 3 SIMs).
