5.7.4 Informative Examples
1. Set CNMI=1,4,0,0,0.(default)
It indicates that the new class1 messages will be stored in the MS first, and report
user by the following special format:
Received SMS:

Orig Address: +8613801000722
Call back Address: +8613801000722
User Data: testing
Note: If keeping CNMI as the default value, while embedded TCP connection, the
module can inform server the process status via SMS.
2. For example, set CNMI=1,1,0,1,0.
It indicates that the new class1 messages will be stored in the MS first, and the
storage position will be reported (+CMTI: ME,1}; the message state reports will be
reported directly (+CDS: ).
When it is impossible to report the message notification (e.g. when in the online data
