CHAPTER 22 - VERIZON® SPECIFIC AT COMMANDS

This chapter details AT commands that are Verizon® specific. The detail presented in this chapter should replace the referenced section in the main document.

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 17 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.
