utils: do not crash when all bytes of EF.IMSI are 0xFF In case try to decode the contents of an uninitalized EF.IMSI, the function dec_imsi() would crash because it truncates all 0xFF from the swapped version of the EF.IMSI contents and then accesses the first element of the buffer. This always works for EF.IMSI contents that contain valid IMSI data, but if all bytes are set to 0xFF, then no data is left in the buffer after truncating, so lets check if we even have bytes left before we move on with the decoding.

This repository contains a Python-language program that can be used to program (write) 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.
The official homepage of the project is http://osmocom.org/projects/pysim/wiki
You can clone from the official libosmocore.git repository using
git clone git://git.osmocom.org/pysim.git
There is a cgit interface at http://git.osmocom.org/pysim/
pysim requires:
Example for Debian:
apt-get install python-pyscard python-serial python-pip pip install pytlv

./pySim-prog.py -n 26C3 -c 49 -x 262 -y 42 -i -s
./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 eg. 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'))
