Hello! I tried searching the mailing list to see if anyone else has had this issue, but I
didn't find anything relevant.
Explanation: I am trying to install my java applets to an older sysmoISIM-SJA2 card with
the "SELECTABLE" and "DEFAULT" privilges/flags. The reason being that
I need my applets to auto select itself rather than manual interaction through the SIM
Toolkit menu. Currently, I am using the shadysim-isim tool to load my applets, however,
there is no option to make applets defaultSelect. And, it doesn't look like pySim
supports this currently either. GlobalProtectPro (gp.jar) does have support for these
cmds, but it looks like they need addtional parameters specific to the SJA2 when
installing.
Does anyone know what the exact parameters needed are? Someone else noted this issue under
the GlobalProtectPro repo - but I'm not really knowledgeable enough to understand what
was said.
Link to the issue: https://github.com/martinpaljak/GlobalPlatformPro/issues/293

There is a typo in my initial post - I meant "GlobalPlatformPro" not
"GlobalProtectPro".

I don't think this is possible at all. The default selected application on a SIM/USIM
card is always the
SIM/USIM native application. Otherwise, how would it ever behave like a SIM/USIM?
If you want a card that is not a SIM/USIM where you can define the default selected
application,
then you should look for a JavaCard without SIM/USIM functionality.

Okay, thanks for the reply!
I wasn't sure because I was going off of this output from the GlobalPlatform tool when
listing my loaded applets. I thought that it might be possible because none of them were
listed as default, but it could just be an incompatibility with the GP tool when reading
the SIM card.
Do you think it would be possible to export the USIM application and make changes? The
concept that I am working on needs to be a SIM javacard and 5G compatible.

I read more of the GlobalPlatform documentation and understand now why the ADF.USIM is
selected first (and why it should be first). The applet doesn't need to be marked as
default - it just needs to be the first "SELECTABLE" among the list.
Attempting to modify the USIM application to run what I need doesn't seem realistic
either :/
If I figure anything out, I will share it here for others as well.

No, the USIM/ISIM, SIM, etc. apps are native apps part of the CardOS.

What exactly is your technical requirement? Please tell us more about what you want to
do.

Okay, yeah that makes sense. I'm very new to SIM programming, hence all the basic and
wrong questions.
>> What exactly is your technical requirement?
Please tell us more about what you want to do.
I just have a basic hello world applet that I'm building off of and the concept
I'm working with requires it to launch without explicit user intervention. My lazy
approach was to attempt making the applet the default; which, I now know is not the right
path for USIM cards.
The ETSI TS 102 241 - V16.0.0 documentation, section 6 (which should be the right release
version for me) describes the correct way to trigger my applet. Rather than using the
toolkit event menu selection. I should be registering a different event like
unrecognized_envelope, timer_expiration, or download_local_connection.
I've mostly been learning from example applets, so I didn't realize there were
other events you could use.
Thank you!
