Hey Baseband,
I've got a stock of SIMs I bought and programmed already, but I
unfortunately (and stupidly) forgot to set the SMSC. This is causing me
heaps of issues, as each phone now has to have the SMSC set manually. I was
hoping to hack up a quick script which just inserts the SMSC onto the SIM
without needing to regenerate the ki or IMSI. Lining those up with my
database is rife with hazard.
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.
Thanks!

Hi,

What type of SIMs exactly and how did you program them ?
pySIM sets a default SMSC if you don't set one ...

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,

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!

You are already lucky that you got the right CardOS, nothing like punching out
thousands of SIM cards by hand and sending them back.

Definitely. Moreso because "sending them back" isn't all that possible
where I am (Papua) anyhow, on account of the lack of a postal service.
