Appendix F: Program the SIM Card

Install packages:

sudo apt-get install pcscd pcsc-tools libccid python-dev swig python-setuptools python-pip libpcsclite-dev
sudo pip install pycrypto

Download PySIM

git clone git://git.osmocom.org/pysim.git

Change to pyscard folder and install

cd <pyscard-path>
sudo /usr/bin/python setup.py build_ext install

Verify your reader is ready

sudo pcsc_scan

Check whether your reader can read the SIM card

cd <pysim-path>
./pySim-read.py –p 0

Program your SIM card information

./pySim-prog.py -p 0 -x 208 -y 93 -t sysmoUSIM-SJS1 -i 208930000000003 --op=8e27b6af0e692e750f32667a3b14605d -k 8baf473f2f8fd09487cccbd7097c6862 -s 8988211000000088313 -a 23605945

You can get your SIM card from sysmocom. You also need a card reader to write your SIM card. You can get a card reader from here or use other similar devices.
