Yes the Option Modems always return +CRSM: 111 -> Unspecified Error whenever we 
use 'GET RESPONSE'.  It seems that this function is simply not implemented in 
their firmware, even though reading files directly from the SIM (in the case of 
EFphase or EFiccid) seems to work.

Unfortunately, with a few exceptions, we actually need to call 'GET RESPONSE' 
first to find the record size / file size before we can attempt to read the file.  
One way to do this might be to use +CSIM to walk the EF tree, but that is 
quite nasty.

This needs to be fixed for the Option driver.  Perhaps someone here knows a 
way...
