Hi Alexander,
Btw, the first release of XTRX (http://xtrx.io) will have a SIM driver, so it'll be possible to connect it directly to a SIM card slot, as per the miniPCIe standard. If users will find this feature useful for users, it'll make it to the final release.
So, that is really good news! Also I think it would be great to extend existing SAP interface/protocol implementation with multiple SIM cards support and finish some unimplemented things in this area.
Also note an 'ms' branch of osmo-trx. It's not a full functionality required for an MS and the code is pretty dated, but it's close enough to start.
Yes, Sylvain already said me about this branch.
It was a combination of circumstances that work was not finished and I would totally support an effort to finish it.
It is nice to know about that. Thank you!
With best regards, Vadim Yanitskiy.

Fortunately, there are many SDR platforms available now. Especially

devices are USRP, UmTRX, bladeRF, and recently introduced LimeSDR. They

easily programmed to support just about any type of wireless standard,
of course,
including some mobile telecommunication stacks. As well as for network
side back-end,
they can be used to perform MS side operations, excepting
frequency-hopping and some
phone specific features (like SIM I/O).

So, I think there is a way to bring a new live to, amazing child of the
Osmocom
umbrella, OsmocomBB. We can make one work on SDR hardware platforms
implementing
a 'bridge' between both already implemented L2/L3 and OsmoTRX.

I know that there already was some attempts (see sylvain/ms-sdr branch) to make described
dreams
come true, but development was stopped. And now I am going to start to
work around
this direction.
