Notes:
• Incoming short messages with message class 1 (ME specific short messages) or class 2 (SM specific short
messages), see <dcs> in GSM 03.38, will be stored either in “ME” or in “SM” storage. Therefore the “^SMGO:
2” indication could occur, without issuing the indication “^SMGO: 1” before. The indication “^SMGO: 1” means
that both buffers (“ME” and “SM”) are full.
• For more information regarding SIM and ME specific message classes refer to <dcs> and the following
specifications: GSM 03.38 and 3GPP TS 23.038.
13.25 AT^SMGR Read Short Message without
Setting Status to REC READ
Description: The AT^SMGR command is a specific command which has the same syntax as
AT+CMGR. The only functional difference is that the status “REC UNREAD” of a short
message is not overwritten to “REC READ”.
Test Command Syntax: AT^SMGR=?
Response: ^SMGR:
OK
Write Command Syntax: AT^SMGR=<index>
Response: see AT+CMGR
Note:
• 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.
