Clarification
TA result code buffer is in volatile memory. Messages may get lost if the power of ME/TA is switched
off before codes are sent to TE. Thus, it is not recommended to use direct message routing (<mt>=2
or 3, <bm>=2 or 3, or <ds>=1) with <mode> value 0 or 2.
When +CSMS <service> is set to 0, all received SMS are automatically stored in SIM before +CMT or
+CMTI URC is sent to TE whatever <mt> value.
When +CSMS <service> is set to 1, depending of it class, SMS has to be acknowledged to network
thanks to +CNMA commands. Depending of <mode>, <mt> and channel status (available or
reserved) URC cannot or should not be sent to TE. In these cases SMS can be automatically
acknowledged or rejected without waiting +CNMA command.
+CNMI parameters are automatically saved in non-volatile memory.
