12.23 AT^SMGL List Short Messages from Preferred Store
without Setting Status to REC READ
Description: The execute command is the same as the write command, but uses the given default of <stat>.
The write command allows to select a status type and lists, from the message storage <mem1>,
all messages that currently have the specified <stat>. The major difference over the standard
command AT+CMGL is that the status of the listed messages remains unchanged (unread
remains unread).
Syntax: Test Command: AT^SMGL=?
Response: same as AT+CMGL
Exec Command: AT^SMGL
Response: ^SMGL: (For default values of <stat>, see Section 12.1 “SMS Parameters”.)
OK
Write Command: AT^SMGL=<stat>
Response: same as AT+CMGL
Notes:
• The selected <mem1> can contain different types of SMs (e.g., SMS-DELIVERs, SMS-SUBMITs, SMS-
STATUS-REPORTs and SMS-COMMANDs). The response may be a mix of the responses of different SM
types. TE application can recognize the response format by examining the third response parameter.
• Users should be aware that when using this AT command quickly after SIM PIN authentication, the SIM data
may not yet be accessible, resulting in a short delay before the requested AT command response is returned.
See Section 20.1, Restricted Access to SIM Data after SIM PIN Authentication.
• This command is PIN protected.
