SMS Status Report Indication Directly Displayed +CDS
Description:
This response indicates an SMS status report has been received and according to the message storage
preferences (+CNMI), is to be directly displayed. +CDS is also used in the data compression functionality as
an active command. Refer to Chapter 16 for an explanation of +CDS usage for data compression.
For Verizon®, the +CDS response has a secondary format that is used to indicate that a SMS message was
delivered to the recipient (SMS message delivery ACK on). This form of the +CDS message is not stored in
NV memory. In the case of delivery acknowledgement, the +CNMI setting will not have an effect and
delivery acknowledgements will always be reported with the +CDS response.
