Depending on the card profile the sysmoUSIM-SJA2 may come with an USIM
application or with an USIM and an ISIM application installed. If the
ISIM application is not present the related application must not get
selected and the related files must not accessed. At the moment the
presence of the ISIM application is detected by checking the ATR,
however the ATR only identifies a certain OS version or type, not an
application. Lets look at the EF.DIR first and dtermine the presence of
the applications by looking for the related AID.
