h1. sysmoUSIM-SJS1
*NOTE: As of October 2020, sysmoUSIM-SJS1 is obsolete and has been superseeded by [[sysmoISIM-SJA2]]*
The sysmoUSIM-SJS1 is programmable and Java capable USIM card. Not all commands are known yet and this page should grow over time. Each card is using a separate ADM1 key and the default configuration is hacker/developer friendly (fields being writable, reduced security for installing applets to have more quick development cycles).

h2. User Manual
sysmocom provides a comprehensive user manual at https://sysmocom.de/manuals/sysmousim-manual.pdf - please refer to that manual rather than this rarely maintained wiki page for most up-to-date reference information.
h2. Tools
h3. pySIM
The sysmoUSIM-SJS1 can be parameterized using pySim and sysmo-usim-tool.
PySim provides the common general bulk provisioning features, which are already known from MagicSIM and previous sysmocom simcard models. Most of the settings (like Ki, ICCIC, OPC, etc...) listed below are covered by PySim.
Please see the *pySim-prog.py* program from @git://git.osmocom.org/pysim@ (http://git.osmocom.org/pysim/) and
h3. sysmo-usim-tool
For tweaking higly sysmoUSIM-SJS1 specific parameters (authentication algorithms, milenage parameters, enable/disable USIM application etc...), sysmo-usim-tool can be used. For more information see section "7.2 sysmo-usim-tool" in the provided manual.
Please see the *sysmo-usim-tool* program from https://git.sysmocom.de/sysmocom/sysmo-usim-tool/
@git://git.sysmocom.de/sysmo-usim-tool@ (http://git.sysmocom.de/sysmo-usim-tool)
h3. SIM Toolkit
Please see [[shadysim.py]] for a tutorial on installing and removing a SIM Toolkit applications.
h3. VoLTE / Android Carrier Privileges / ARA-M / IMS Configuration
If you want to use IMS (VoLTE/VoWiFi) on android devices, you will need to grant an android app special carrier privileges. This is done by storing a hash of the singing key of the android app on the SIM.
See [[VoLTE_IMS_Android_Carrier_Privileges]] for details.
h2. Availability
sysoUSIM-SJS1 is (as of October 2020) no longer available. Its succesor [[sysmoISIM-SJA2]] is available from http://shop.sysmocom.de/products/sysmoISIM-SJA2
h2. Command Reference
*Please primarily refer to the user manual for more detailed information!*
To understand this reference, it is assumed that you are familiar with basic knowledge on smartcard
technologies, such as standard ISO 7816-3/-4 APDUs and GSM TS 11.11.
The below should be possible to set after authenticating with the ADM1 pin
h3. Setting the IMSI
Use a standard UPDATE BINARY command on EF.IMSI (7F20/6F07)
h3. Setting the ICCID
Use a standard UPDATE BINARY command on EF.ICCID (2FE2)
h3. Setting the Ki
