I've had the same exact thought here independently.  Funny that you're
thinking along the same lines.

Unfortunately DisplayText / Get Input and Select Item can be started
outside a main menu selection, at least according to GSMA DG.11 Device
Field and Lab Test Guidelines Section 8.9.15.

I need to dig into that spec some more, but looks like any SMS-Data
download can trigger a USAT command, no matter what is currently
happening (unless the SIM is busy of course.)
