WinSIM Pro

If you're a SIM card engineer looking for a professional tool to view and modify the contents of GSM SIM, 3G USIM, or CDMA R-UIM cards, then Classicalsoft WinSIM Pro is the software for you. This application offers an effective and sophisticated design that makes editing APDU commands before sending to your card easy. With history commands that auto-fill fixed parameters, all you need to do is select and write only the necessary part of the command. And if you're a veteran SIM expert, you can use the script way for the next time in a project, which will save you a lot of time and effort.

WinSIM Pro offers a wide variety of smart card readers, making it compatible with all smart card readers that comply with the PC/SC specification. Its file manager also grants you access to any file on your card, interpreting the properties of each file. The command manager allows for quick and easy sending of an APDU command with customized parameters, and the script manager offers a useful way to organize and play a batch of commands. Additionally, the trace manager keeps track of all transmitted APDU commands and responses.

To use this software, you'll need a personal computer with an available port (e.g., COM, USB) for the smart card reader, a PC/SC compliant smart card reader, and a smart card reader driver. Keep in mind that WinSIM Pro has a 20-use trial limit and a nag screen.
