filesystem: fix decode_select_response There are some problems with the usage of decode_select_response. At the moment the ADF files overload the related method to provide decoding of the select responses as per 3gpp TS 102 221. However, this also means that the decoder is only available under ADF.USIM and ADF.ISIM. DF.GSM and DF.TELECOM also overload the decoder method, just like an ADF would do. This decoding method is then implemented as per 3gpp TS 51 011. Since this a a problem on UICCs, the method detects the magic byte 0x62 that can be found at the beginning on every select response of an UICC to defer to the TS 102 221 decoding method. TS 51 011 defines the first two bytes of the select response as RFU. This at least problematic. To solve this there should be a default method for decode_select_response in the profile, which can be used if no file overloads it with a specific decoder. ADFs use specific decoders, but everything else should use the default decoder. When we deal with an UICC, we expect the select response to be consistantly conform to TS 102 221, if we deal with a clasic sim we expect responses as per TS 51 011 only. Since it is still possible to replace the select response decoder we still have the opportunity to have custom select response in cartain DFs and ADFs should we need them.

This repository contains Python programs that can be used to read, program (write) and browse certain fields/parameters on so-called programmable SIM/USIM cards.
Such SIM/USIM cards are special cards, which - unlike those issued by regular commercial operators - come with the kind of keys that allow you to write the files/fields that normally only an operator can program.
This is useful particularly if you are running your own cellular network, and want to issue your own SIM/USIM cards for that network.
Please visit the official homepage for usage instructions, manual and examples.
You can clone from the official Osmocom git repository using
git clone git://git.osmocom.org/pysim.git
There is a cgit interface at https://git.osmocom.org/pysim
Please install the following dependencies:
Example for Debian:
apt-get install python3-pyscard python3-serial python3-pip python3-yaml pip3 install -r requirements.txt
After installing all dependencies, the pySim applications pySim-read.py
, pySim-prog.py
and pySim-shell.py
may be started directly from the cloned repository.
Archlinux users may install the package python-pysim-git
from the Arch User Repository (AUR). The most convenient way is the use of an AUR Helper, e.g. yay or pacaur. The following example shows the installation with yay
.
# Install yay -Sy python-pysim-git # Uninstall sudo pacman -Rs python-pysim-git
There is no separate mailing list for this project. However, discussions related to pysim-prog are happening on the openbsc@lists.osmocom.org mailing list, please see https://lists.osmocom.org/mailman/listinfo/openbsc for subscription options and the list archive.
Please observe the Osmocom Mailing List Rules when posting.
Our coding standards are described at https://osmocom.org/projects/cellular-infrastructure/wiki/Coding_standards
We are using a gerrit-based patch review process explained at https://osmocom.org/projects/cellular-infrastructure/wiki/Gerrit
./pySim-prog.py -n 26C3 -c 49 -x 262 -y 42 -i <IMSI> -s <ICCID>
./pySim-prog.py -n 26C3 -c 49 -x 262 -y 42 -z <random_string_of_choice> -j <card_num>
With <random_string_of_choice>
and <card_num>
, the soft will generate 'predictable' IMSI and ICCID, so make sure you choose them so as not to conflict with anyone. (for e.g. your name as <random_string_of_choice>
and 0 1 2 ... for <card num>
).
You also need to enter some parameters to select the device:
-t TYPE : type of card (supersim
, magicsim
, fakemagicsim
or try auto
)
-d DEV : Serial port device (default /dev/ttyUSB0
)
-b BAUD : Baudrate (default 9600)
from pySim.transport.serial import SerialSimLink from pySim.commands import SimCardCommands sl = SerialSimLink(device='/dev/ttyUSB0', baudrate=9600) sc = SimCardCommands(sl) sl.wait_for_card() # Print IMSI print(sc.read_binary(['3f00', '7f20', '6f07'])) # Run A3/A8 print(sc.run_gsm('00112233445566778899aabbccddeeff'))
