G5/G6-Family AT Commands User Manual Page
After sending a +CDS unsolicited response to the TE, the Module will expect a +CNMA (new message
acknowledgment) from the TE within a predefined timeout of 60 seconds. The Module will not send
another +CDS unsolicited response to the TE before the previous one is acknowledged. If the +CDS is
acknowledge d within the timeout, the new SM is not saved in the message storage. If the +CDS is not
acknowledged and the timeout has expired, the new SM is saved in the message storage and +CNMI
parameter <ds> is set to ā0ā.

7.1.11+CMGL, +MMGL,List Messages
These commands display a list of all SMS with the status value <stat>, from the Module message storage
<mem1> (selected using the +CPMS command). The command returns a series of responses, one per
message, and each containing the message index, status, and data. If the status of a message is
"RECEIVED UNREAD", execution of the +CMGL command changes the status of the message to
"RECEIVED READ".
The +MMGL command does not change the message status. In addition, +MMGL includes a <stat>
selection that can be used to query the Module for a list of message headers without attendant message
data.
