USIM modifier

Abstract

This is my 2nd practice project with Python, and it's a flexible SIM tool to modify some SIM files.
Yes, the tool is not a perfect tool for USIM modify, but I think its enough for most requirement.

The project was stop to enhance due to have new plan for next major release. In this project, I found the architectue is not good and cause so many issues, below items are my expected for next major release:

  1. Multiple language support with plugin.
  2. More rigorous error handling to avoid the system crash if error occurs.
  3. Provide 'security' (PIN manager) plugin on system level

PS. Even I stop to enhance this projet, but will kept to resolve bugs.
