Installation

This application uses WINSCARD on Windows Systems or PCSC-Lite for Linux and Mac OSX systems. Ensure the required software and services for your OS are already enabled. In order to compile in Windows, Visual C++ Python 2.7 compiler needs to be installed as well.

Then, ensure the following dependencies are already installed in your system:

• Python 2.7
• SWIG
• GIT

Once all dependencies are installed, download the source code and execute:

$ python setup.py install

The setup.py file should downloads all python dependencies (asterix, pyscard, pycrypto, ecdsa). Resolve building dependencies yourself when compiling error occurs.

FAQ

What is a roaming steering list? A roaming steering list is a set of preferences that steer the SIM card connectivity to certain networks. Carriers install those lists on SIM cards to steer roaming behaviour, so the best quality networks are selected outside of the home network, or for avoid expensive networks costs (depending on your plan).

What do all those MCC, MNC, PLMN, FPLMN acronyms mean? MCC stands for Mobile Country Code, MNC for Mobile Network Code. The ITU-T Recommendation E.212 defines both MCC and MNC lists worldwide. A PLMN, or Public Land Mobile Network is a network ID formed by the combination of MCC and MNCs: e.g. 23410 refers to UK country (MCC: 234) and O2 network (MNC: 10). A FPLMN is simply a forbidden PLMN the device should avoid connecting to. Read the Mobile Country Code article on Wikipedia for further information.
