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.

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.

It was a combination of circumstances that work was not finished and I
would totally support an effort to finish it.
