Hello,
some years ago I have developed a working SIM card emulator for Silver Wafer Card (PIC16F877 and 24LC256).
It supports GSM 11.11 and GSM 11.14 standards and is fully functional inside cell phone (so far I have been using it for 10+ years).
Unfortunately it is written in somewhat rusty PIC assembly -- still it might be usable for your purposes.
I have published it on "https://github.com/vlp/ssim", so feel free to have a look.
Best regards
VLP
Thanks for all the answers. Everything is fine up to now.
May i ask if you know a list of the available apdu commands for SIM and
USIM?
Thanks

Good evening.
I am interested in your SIMtrace hardware board and i would like to ask
a few questions if possible. ( http://bb.osmocom.org/trac/wiki/SIMtrace)
First of all i am interested in sniffing data between both SIM and USIM.
As a result, i would like to ask if your product fully works with these
cards and if i will be able to capture all the data between the mobile
terminal and the (U)SIM. (eg. usim authentication)
Furthermore, i have some queries about the wireshark integration.
The wireshark intefration supports the GSMTAP protocol. this protocol is
used in order to parse the data between the SIM card and the mobile
terminal. Does this protocol also supports parsing data between the USIM
and the mobile terminal?
Thanks
Stefanos
Hi all!
I *think* Harald is pretty busy and also unlikely to attend
prospective meeting tomorrow.
Also there is bank holiday tomorrow in Germany and at least
I personally will use that to stay away from technology for
a bit, so I won't come.
Nevertheless, I thought I'd write this email to remind
people that in theory there is a meeting tomorrow and
discuss if other people attend.
I personally would propose to shift the meeting to next week
(for purely selfish reasons ;).
As far as I know, there is no formal presentation tomorrow.
Anyway, will anyone attend tomorrow or is everyone in favor
of shifting a week?
In case it takes place, for the people who did not attend so
far, the usual snippet from Harald's mails:
Oct 3, 8pm @ CCC Berlin, Marienstr. 11, 10113 Berlin
If you are interested to show up, feel free to do so. There is no
registration required. The meeting is free as in "free beer", despite
no actual free beer being around.
Cheers
Nico
