BE WARNED: The Sysmcom.de people are rough and narrow minded. They are rude on asking technical support for OpenBTS, OpenBSC, YateBTS and OpenLTE; treat these open source projects as competitors :-(
That's a real personal experiance, I bought sysmoUSIM-SJS1 a few days ago; they intentional did not reply what I had been asking for, but pretended to cooperative; otherwise.
I therefore, am alerting all of you for not to buy and, or use their products and third class after sales/support services. I'm quoting 2 recent replies from Harald Welte:
We are unable to support you with questions related to third-party software
such as YateBTS. Please contact the software supplier for assistance on ho to
enroll/configure subscribers there. We have never used related software and can
not comment on how it needs to be configured for our sysmoUSIM-SJS1 sim cards.
All related technical details about our cards can be found in the
sysmoUSIM-SJS1 user manual.

We sell our sysmoUSIM cards primarily for the customers of our own BTS
and small network products such as sysmoBTS and sysmoNITB/IP.
If you chose to use a competitor product, that is of course your free
choice, and we are (believe it or not) happy with that.
But we absolutely cannot support you with issues of any product that we
have never even seen. Until your e-mail I didn't even know that YateBTS
contained some explicit/specific support for our cards.
If you should find any malfunction or defect in our cards, we are happy
to assist you. But your question is about the YateBTS software.
