Have you done the work to learn *which* of these several AT commands are 
the ones that made the difference?

For example, in your ModemResetCmds you have ATS0=0 which certainly can 
be removed.  Likewise ATE0.  I'm not sure about AT&D2 and AT&C1, but I 
think that these are basic configuration settings that would be best 
altered elsewhere (other than ModemResetCmds).  AT&F probably 
accomplishes the same thing as ATZ, so that's unnecessary most likely.  
ATV1 is also probably not needed or is better configured elsewhere.  So 
I think that brings us down to:

AT+MR=0, AT+DR=1, AT+ER=1, and AT+ILRR=0.  Do you know what these 
settings do?

Do the traditional AT&K, AT&K3, and AT&K4 not work on your modem?
