pySim - Read, Write and Browse Programmable SIM/USIM Cards
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.
Homepage and Manual
Please visit the official homepage for usage instructions, manual and examples. The user manual can also be built locally from this source code by
cd docs && make html latexpdf for HTML and PDF format, respectively.
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:
- cmd2 >= 1.3.0 but < 2.0.0
- construct >= 2.9.51
- pyyaml >= 5.1
Example for Debian:
sudo apt-get install --no-install-recommends \ pcscd libpcsclite-dev \ python3 \ python3-setuptools \ python3-pyscard \ python3-pip pip3 install --user -r requirements.txt
After installing all dependencies, the pySim applications
pySim-shell.py may be started directly from the cloned repository.
Archlinux users may install the package
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
# 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 firstname.lastname@example.org mailing list, please see https://lists.osmocom.org/mailman/listinfo/openbsc for subscription options and the list archive.

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
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.
pySim-shell vs. legacy tools
While you will find a lot of online resources still describing the use of pySim-prog.py and pySim-read.py, those tools are considered legacy by now and have by far been superseded by the much more capable pySim-shell. 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.
