A python tool to program SIMs / USIMs / ISIMs
This repository contains a number of Python programs related to working with
subscriber identity modules of cellular networks, including but not limited
to SIM, UICC, USIM, ISIM, HPSIMs and eUICCs.
pySim-shell.py
can be used to interactively explore, read and decode contentspySim-read.py
and pySim-prog.py
are legacy tools for batch programmingpySim-trace.py
is a tool to do an in-depth decode of SIM card protocol tracesosmo-smdpp.py
is a proof-of-concept GSMA SGP.22 Consumer eSIM SM-DP+ for lab/researchcontrib
directory.Note that the access control configuration of normal production cards
issue by operators will restrict significantly which files a normal
user can read, and particularly write to.
The full functionality of pySim hence can only be used with on so-called
programmable SIM/USIM/ISIM/HPSIM cards, such as the various
sysmocom programmable card products.
Such SIM/USIM/ISIM/HPSIM 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 configure your own SIM/USIM/ISIM/HPSIM cards for
that network.
Please visit the official homepage
for usage instructions, manual and examples.
The pySim user manual can be built from this very source code by means
of sphinx (with sphinxcontrib-napoleon and sphinx-argparse). See the
Makefile in the ‘docs’ directory.
A pre-rendered HTML user manual of the current pySim ‘git master’ is
available from https://downloads.osmocom.org/docs/latest/pysim and
a downloadable PDF version is published at
https://downloads.osmocom.org/docs/latest/osmopysim-usermanual.pdf.
A slightly dated video presentation about pySim-shell can be found at
https://media.ccc.de/v/osmodevcall-20210409-laforge-pysim-shell.
While you will find a lot of online resources still describing the use ofpySim-prog.py
and pySim-read.py
, those tools are considered legacy by
now and have by far been superseded by the much more capablepySim-shell.py
. We strongly encourage users to adopt pySim-shell, unless
they have very specific requirements like batch programming of large
quantities of cards, which is about the only remaining use case for the
legacy tools.
You can clone from the official Osmocom git repository using
git clone https://gitea.osmocom.org/sim-card/pysim.git
There is a web interface at https://gitea.osmocom.org/sim-card/pysim.
Please install the following dependencies:
github.com/hologram-io/smpp.pdu
)Example for Debian:
sudo apt-get install --no-install-recommends \
pcscd libpcsclite-dev \
python3 \
python3-setuptools \
python3-pycryptodome \
python3-pyscard \
python3-pip
pip3 install --user -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.
In addition to the dependencies above pySim-trace.py
requires tshark
and the python package pyshark
to be installed. It is known that the tshark
package
in Debian versions before 11 may not work with pyshark.
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
We welcome any pySim related discussions in the
