They're programmable as 'sysmosim-gr1' with pysim, that's all I really
know. I bought them programmed from a vendor in China, who promptly screwed
up the SMSC on 1000 sim cards.
I'll take a look at the branch, seems very similar to what I need. Thanks!

Hi,
I've got a stock of SIMs I bought and
programmed already, but I
unfortunately (and stupidly) forgot to set the SMSC.
What type of SIMs exactly and how did you program them ?
pySIM sets a default SMSC if you don't set one ...
Looking at the pySim-prog, it looks like this
probably isn't possible;
all
of the data seems to get bundled together and so
changing the SMSC length
will cause other data to be corrupted. Is that right? I just wanted to
see
what ya'll think would be the best way for me
to remedy my particular
stupidity.
If you look in the ccc branch of pySIM, there is a ccc-fix.py script
that was written during 27C3 for fixing SMSC on cards we wrote (at the
time pysim was creating a corrupt smsc entry).
It won't work "as-is", but you can look at the internal logic and
adapt ... essentially it read the personalization file, fix it and
rewrites it entirely.
Cheers,
Sylvain
