The dec_plmn function takes an hexstring and returns the decoded MCC and MNC as integer values. The result is then used by the json encoder in EF_PLMNsel, which means the json output will contrary to the input, use integer values instead of strings. This is not correct since there may be leading zeros (e.g. mnc 01 and 001 both exist are different) which must be retained in order to know the correct length of the MNC.

pySim-prog - Utility for programmable SIM/USIM-Cards
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.

Usage
- 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 -s
- 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>
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)
- Interact with SIMs from a python interactive shell (ipython for eg :)
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'))
