Ah, I see now.  Yes you are correct.

Yes, the intent is for the gory details to be taken care of by the sim 
atom driver.  Most 'real' phone modems provide an unsolicited 
notification for this.  If the hardware does not provide such a 
notification then you have to poll.  If you can make Huawei work with 
^SIMST, that would be great as well.  It should work similarly to the 
IFX XSIM or the MBM EPEV notification.
