SMS Status Report Indication Directly Displayed +CDS
(Chapter 3)
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 17for an
explanation of +CDS usage for data compression.
For Sprint®, 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.
