View Full Version : SIM Scan 2.00 bugs/unreliability?

Hi,

I have the SIM card reader supplied as part of the "Super SIM 16 in One" package. This is a basic serial port reader, compatible (I think) with the Phoenix reader.

I have been able to use software like CARDinal and Woron Scan with this reader with no problems.

Using the v7.00 software from the manufacturer (http://www.flash-storage.com/), I was able to find Ki for one of my SIM cards. That program does a brute force attack (I think). The later v7.01a software includes SIM Scan and runs it instead, the idea being that SIM Scan is better/faster.

However, SIM Scan doesn't work properly for me. When "Find Ki" is selected, SIM Scan usually runs a few iterations, then seems to lock up. The only way around that is if I remove the SIM card from the reader, wait until SIM Scan shows an error message, then reinsert it. Then a few more iterations are done before another lock up.

Also, if I try to exit SIM Scan while it is scanning, choosing Exit in the dialog box that appears does nothing; the program just continues.

My machine is quite old and slow (Pentium 1 75MHz, Windows 95 OSR2.5), but other SIM-reading programs seem to work okay.

Has anyone else had problems like these with SIM Scan?

Yes, it has happened with every SIM card I tried. That's why I suspect the problem is with SIM Scan - maybe in the serial-port comms routines?

Which reader do you have, and what value did you change the crystal to? The SuperSIM reader uses a 7.14MHz crystal. Or at least, that's what I have to set the rate to in reader programs (19200 bps). I haven't taken it apart to check the actual crystal frequency.
