Parameters:

displayed with AT&V.
0 Disable. Default. This is the default value if the parameter is omitted (0 will be assumed). This is
also the factory default value and can be restored to '0' with AT&F.

<mode> SMS overflow status. This parameter can be displayed with AT&V.
0 Space available.
1 SMS buffer full. The buffer for received short messages is <mem3>. See AT+CPMS.
2 Buffer full and new message waiting in SC for delivery to phone.
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.
• This command is PIN protected.
• This command is supported in airplane mode.
12.25 AT^SMGR Read Short Message without Setting
Status to REC READ
Description: The AT^SMGR command is a proprietary 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”.
Syntax: Test Command: AT^SMGR=?
Response: ^SMGR:
OK
Write Command: AT^SMGR=<index>
Response: see AT+CMGR
Notes:
• 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 for further details.
• This command is PIN protected.
• This command is supported in airplane mode.
