Parameter Type Description
<index> Number Storage position
<stat> String Indicates the status of message in memory:
• "REC UNREAD": received unread SMS
• "REC READ": received read SMS
• "STO UNSENT": stored unsent SMS
• "STO SENT": stored sent SMS
<oa> String Originator address
<alpha> String Alphanumeric representation of <da> or <oa> corresponding to the entry found in the
phonebook 3GPP TS 24.008 [12]. The parameter is not managed.
<scts> String Service center time stamp in time-string format, refer to <dt>
<tooa> Number Type of address of <oa> - octet
<fo> Number First octet of the SMS TPDU (see 3GPP TS 23.040 [8])
<pid> Number TP-Protocol-Identifier (default 0); see 3GPP TS 23.040 [8]
<dcs> Number Data Coding Scheme
<sca> String Service center address field
<tosca> Number Type of address of <sca> - octet in Number format (for more details see 3GPP TS
24.008 [12]); default 145 when string includes '+', otherwise default 129
<length> Number Number of characters
<seq> Number Sequence number of the current short message (1-255)
<max> Number Maximum number of short messages in the concatenated short message (1-255)
<iei> Number Information Element Identifier, the possible values are the following:
• 0: Concatenated short messages, 8-bit reference number
• 8: Concatenated short messages, 16-bit reference number
<ref> Number Concatenated short message reference number:
• 0-255: concatenated short messages, 8-bit reference number case
• 0-65535: concatenated short messages, 16-bit reference number case
<data> String In the case of SMS: 3GPP TS 23.040 [8] TP-User-Data in text mode responses;
format:
• if <dcs> indicates that 3GPP TS 23.038 [7] GSM 7 bit default alphabet is used and
<fo> indicates that 3GPP TS 23.040 [8] TP-User-Data-Header-Indication is not set:
o if TE character set other than "HEX" (see the +CSCS AT command description):
ME/TA converts GSM alphabet into current TE character set according to rules
of 3GPP TS 27.005 [16] Annex A
o if TE character set is "HEX": ME/TA converts each 7-bit character of GSM
7 bit default alphabet into two IRA character long hexadecimal number (e.g.
character Æ (GSM 7 bit default alphabet 28) is presented as 1C (IRA 49 and 67))
• if <dcs> indicates that 8-bit or UCS2 data coding scheme is used, or <fo> indicates
that 3GPP TS 23.040 [8] TP-User-Data-Header-Indication is set: ME/TA converts
each 8-bit octet into two IRA character long hexadecimal number (e.g. octet with
integer value 42 is presented to TE as two characters 2A (IRA 50 and 65))
In the case of CBS: 3GPP TS 23.041 [9] CBM Content of Message in text mode
responses; format:
• if <dcs> indicates that 3GPP TS 23.038 [7] GSM 7 bit default alphabet is used:
o if TE character set other than "HEX" (see the +CSCS AT command description):
ME/TA converts GSM alphabet into current TE character set according to rules
of 3GPP TS 27.005 [16] Annex A
o if TE character set is "HEX": ME/TA converts each 7-bit character of the GSM 7
bit default alphabet into two IRA character long hexadecimal number
if <dcs> indicates that 8-bit or UCS2 data coding scheme is used: ME/TA converts
each 8-bit octet into two IRA character long hexadecimal number
<da> String Destination address
<toda> Number Type of address of <da> - octet
<vp> Number Format depending of the <fo> setting:
