Hello msfu,
i have an issue with sysmo-usim-tool. If i do
sudo ./sysmo-usim-tool.sjs1.py -a 4051049678932293688 -o

maybe i spelled the adm wrong. but it is calculated from hex 3838383838383838.
What actual SIM or USIM card model are you trying to program? If it's
anything recent from Sysmocom (SJS1 or SJA2), those cards do *not*
have hex 3838383838383838 as their ADM key - instead their ADM1 keys
are randomly assigned per card, and the only way to find out the
correct ADM1 key for your specific card (usually expressed as 8
decimal digits, as they use the ASCII-decimal subset out of the full
64-bit key range) is to look at the key material email you must have
received from Sysmocom webshop at the time of your order.
The only card model I know of that has hex 3838383838383838 (equivalent
to ASCII-decimal 88888888) as its default ADM key is GrcardSIM2.
However, Sysmocom stopped selling those cards ages ago, and in fact
the Sysmocom-branded version of this card (called sysmoSIM-GR2 in its
day) was so rare that I have never even seen one with my own eyes -
I'm guessing it must have been very short-lived. However, the original
manufacturer of those cards (Grcard) still have that model available
(or at least it was available from them about this time last year),
and I got a batch of 200 of those cards made:

If anyone would like some of these FCSIM1 cards, I can make them
available. They are meant to be programmed with my C-language tools
though, *not* with Osmocom/Sysmocom Python tools:

When programmed correctly (I recommend COMP128v3), these SIM cards
(inserted into GSM/2G phones) do work quite well with a GSM network
that is operated with Osmocom CNI software. :-)
