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!

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.
