Keep in mind that often devices don't let you get the IMSI (sim ID)
until you've unlocked the SIM.  Some don't even allow you get the IMEI
until you've unlocked the SIM.  Which is one reason it's hard to
automatically unlock the SIM, since for many devices there's imply no
way to match up the PIN with anything that identifies the device/SIM
that the pin belongs to...  so a generic solution here doesn't work
well.  Best we get is "best effort" I think, if there's an IMSI then use
it, if not try IMEI, if not try USB IDs, if not try model # or something
like that.
