9.18. AT+QCMGR Read Concatenated Messages
The function of this command is similar to AT+CMGR, except that the message to be read is a segment of
concatenated messages, and parameters <uid>, <msg_seg> and <msg_total> would be shown in the
result. Several segments should be concatenated to a whole concatenated message according to these
three parameters. Similar to AT+QCMGS, AT+QCMGR is only used in text mode (AT+CMGF=1).
