result code is sent when ME does not have other display device than AT interface.

acknowledgement command must be sent when +CSMS <service> value equals 1 and ME does not have other display
device than AT interface.
3)
acknowledgement command must be sent when +CSMS <service> value equals 1.

(the rules for storing received CBMs depend on its data coding scheme (refer 3GPP TS 23.038
[2]), the setting of Select CBM Types (+CSCB) and this value; refer table 3):
0
No CBM indications are routed to the TE.
1
If CBM is stored into ME/TA, indication of the memory location is routed to the TE using
unsolicited result code:
+CBMI: <mem>,<index>
9
New CBMs are routed directly to the TE using unsolicited result code:
+CBM: <length><CR><LF><pdu> (PDU mode enabled); or
+CBM: <sn>,<mid>,<dcs>,<page>,<pages><CR><LF><data> (text mode enabled)
If ME supports data coding groups which define special routing also for messages other than class 3 (e.g.
(U)SIM specific messages), ME may choose not to route messages of such data coding schemes into TE
(indication of a stored CBM may be given as defined in <bm>=1).
10
Class 3 CBMs are routed directly to TE using unsolicited result codes defined in <bm>=2. If
CBM storage is supported, messages of other classes result in indication as defined in
<bm>=1.
