UICC and old SIM cards can be difficult to tell apart without prior knowledge of the card. The ATR won't tell if the card is UICC or not. The only remaining option is to try out if the card is able to handle UICC APDUs. The same is true for 2G SIM cards. It is not guranteed that every UICC card will have 2G functionality. Lets add functionality to match a profile to the currently plugged card by actively probing it. Lets also add another profile to distinguish between UICC-only cards and UICC cards that include SIM functionality. Change-Id: If090d32551145f75c644657b90085a3ef5bfa691 Related: OS#5274
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.
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:
- cmd2 >= 1.3.0 but < 2.0.0
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-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.

We are using a gerrit-based patch review process explained at https://osmocom.org/projects/cellular-infrastructure/wiki/Gerrit
- Program customizable SIMs. Two modes are possible:
- one where you specify every parameter manually:
./pySim-prog.py -n 26C3 -c 49 -x 262 -y 42 -i <IMSI> -s <ICCID>
- one where they are generated from some minimal set:
./pySim-prog.py -n 26C3 -c 49 -x 262 -y 42 -z <random_string_of_choice> -j <card_num>
<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
0 1 2 ... for
You also need to enter some parameters to select the device:
-t TYPE : type of card (
fakemagicsim or try
-d DEV : Serial port device (default
-b BAUD : Baudrate (default 9600)
- Interact with SIMs from a python interactive shell (e.g. ipython):
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'))
