Parameter
<uid> Message identification in the user data header (UDH). Range from 0 to 65535 (see
NOTES). All segments of a same concatenated message have same <uid>.
Different concatenated messages should have different <uid>.
<msg_seg> Sequence number of a concatenated message. Range from 1 to 7.
<msg_total> The total number of the segments of one concatenated message. Range is from 2 to 7.
Other parameters please refer to AT+CMGR
1. The <uid> in AT+QCMGR is different from the <uid> in AT+QCMGS. It is possible that UE receives
concatenated messages with 8 bits or 16 bits <uid>. So its maximal value is 255 with 8 bits and
65535 with 16 bits.
2. If the message to be read is not a concatenated message, <uid>, <msg_seg> and <msg_total>
would not be showed in the result.
Example
+CMTI: "SM",3 //The first message of a concatenated message comes
+CMTI: "SM",4 //The second message of a concatenated message comes
AT+QCMGR= 3 //Read the first segment of the concatenated message
+QCMGR: "REC UNREAD","+8615056913384",,"13/07/30,14:44:37+32",120,1,2
ABCD
OK
AT+QCMGR= 4 //Read the second segment of the concatenated message
+QCMGR: "REC UNREAD","+8615056913384",,"13/07/30,14:44:37+32",120,2,2
EFGH
OK
+QCMGR:
<stat>,<fo>,<ct>[,<pid>,[<mn>],[<da>],[<toda>],<length><
CR><LF><cdata>]
