3GPP TS 27.005 AT COMMANDS FOR SMS AND CBS
85 AT Commands for EV-DO-EV3 Modems
For Verizon:
0 - Normal (factory default)
1 - High
<enc_type> - Encoding type of message.
0 - 8-bit Octet
2 - 7-bit ASCII
4 - 16-bit Unicode
<length> - Length of message.
<data> - Message data.
Notes
 Some information appears depending on the last +CSDH setting.
 Regardless of <mode> a message is saved in SMS memory storage. When <mode> is 2, the message displays
and saves to memory storage.
 Reference: GSM 27.005.
 DTR signal is ignored, hence the indication is sent even if the DTE is inactive ( DTR signal is Low). In this case
the unsolicited result code may be lost so if module remains active while DTE is not, at DTE startup is
suggested to check whether new messages have reached the device meanwhile with command AT+CMGL=0
that lists the new messages received.
