The metaclass uese the 'nested' attribute, while the existing code accidentially used the 'children' attribute. The latter is used by instances for actual child classes, while the Class/nested attribute is for the list of classes whose instancse could be potential children.

pySim - Read, Write and Browse Programmable SIM/USIM/ISIM/HPSIM Cards
This repository contains a number of Python programs that can be used to read, program (write) and browse all fields/parameters/files on SIM/USIM/ISIM/HPSIM cards used in 3GPP cellular networks from 2G to 5G.
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 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.
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describing the use of pySim-prog.py and pySim-read.py, those tools are considered legacy by now and have by far been superseded by the much more capable pySim-shell.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.
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 >= 1.5.0
- construct >= 2.9.51
- pyyaml >= 5.1

Example for Debian:
sudo apt-get install --no-install-recommends \ pcscd libpcsclite-dev \ python3 \ python3-setuptools \ python3-pycryptodome \ 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.
In addition to the dependencies above
tshark and the python package
pyshark to be installed. It is known that the
in Debian versions before 11 may not work with pyshark.
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
