Dieter Spaar has modified the shadysim.py to support the configured OTA mode on the sysmoUSIM-SJS1 (and by extension the SIM Cards issued at 31C3, the following camp and 32C3).

h2. What is it about
4
5
(U)SIM cards are Java capable and there is the Globalplatform that specifies standards API. SMS can be addressed directly to the SIM card, the SIM card will get events for network selection and others, it can modify call establishment attempts.

The following will show how to build the example applet and install it on your USIM. If you create plugins please make them available as Free Software and point us to them. If you find interesting Globalplatform APIs or hacks please talk about it.

h2. What you will need
10
11
* sysmoUSIM-SJS1 card
12
* KIC, KID private keys of the card
13
* PCSC, serial card reader or be able to send SMS to the SIM card
14
* JDK to create Java1.1 bytecode to create/customize SIM Toolkit applets.

h2. What you can read
18
19
* JavaCard? API specification (​http://www.andresteder.com/static/api/simtoolkitapi/sim/toolkit/package-summary.html)
20
* 3GPP sim.toolkit API (​http://www.etsi.org/deliver/etsi_ts/101400_101499/101476/07.00.00_60/ts_101476v070000p.pdf). Specially setEvent is a good keyword to look at!

h2. Building an example applet
24
25
<pre>
26
git clone git://git.osmocom.org/sim/sim-tools/
27
git clone git://git.osmocom.org/sim/hello-stk
28
cd hello-stk
29
make
30
ls -la ./build/javacard/org/toorcamp/HelloSTK/javacard/HelloSTK.cap
31
</pre>

33
If you have a javac in your system you have now built an example Helloworld applet.

h2. Working with a PC/SC reader
36
37
Make sure you have the KIC1, KIC2, KIC3 and KID1, KID2 and KID3 for your card. If you have a CCC Event card from 31C3 or later you should be set and for the sysmoUSIM-SJS1 be sure to buy the option that includes the ADM1 keys as otherwise no OTA keys will be provided to you (you will have to buy a new batch of cards then).

h2. Working with a SMPP reader
61
62
Instead of directly interacting with the SIM through a PCSC reader the APDU is sent through SMPP. Replace the --pcsc call with --smpp and lines starting with SMPP are printed. These then need to be sent.
