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.
Modern SIM cards may come with multiple applications installed (e.g. an
additional ISIM application along with a regular USIM application). In
some debug cases it may be helpful to be able to list those
applications. Lets add some functionality for that.
Adding support for the new SJA2 simcard type requires comprensive
refactoring of sysmo-usim-tool. We resolve the commonalities of
both simcard models in a class based approach so that code duplication
is reduced to a minium.
- Refactor sysmo-usim-tool into a class based model
- Add support for SJA2 simcard models
- Add tests for SJA2 simcard models
