pySim - Read, Write and Browse Programmable SIM/USIM Cards pySim - Read, Write and Browse Programmable SIM/USIM/ISIM/HPSIM Cards
==================================================== =====================================================================
This repository contains Python programs that can be used This repository contains a number of Python programs that can be used
to read, program (write) and browse certain fields/parameters on so-called programmable to read, program (write) and browse all fields/parameters/files on
SIM/USIM cards. SIM/USIM/ISIM/HPSIM cards used in 3GPP cellular networks from 2G to 5G.
Such SIM/USIM cards are special cards, which - unlike those issued by Note that the access control configuration of normal production cards
