Problem when MS attempts short READ BINARY (less bytes than file length)

DLGLOBAL NOTICE => IRQ STATUS: flags=0x10, fi=1, di=1, wi=10 wtime=9600 (RESET )

so what happens here

SELECT DF.GSM
SELECT EF.PHASE
- 9f0f indicates 10 bytes available
- READ BINARY of 1 byte
- swsim returns 9f01 rather than the actual byte that was attempted to read

this is how it looks like with a real SIM:

DLGLOBAL INFO => DATA: flags=0x01 (HDR ), a0 a4 00 00 02 
 DLINP DEBUG [0] <= osmo_st2_cardem_request_pb_and_rx(pb=a4, le=2)
