Note
· If a mobile station is able to display short messages, class 0 messages can be
displayed immediately. If the mobile station has no display, class 0 messages
shall be treated as though there was no message class. Refer to GSM 03.38.
· The only effect of AT^SSDA is to influence the behavior of the <mt> parameter
specified with AT+CNMI: If <da>=1 and <mt>=1, then Class 0 short messages
need to be acknowledged with AT+CNMA. See also Chapters 5.9 for CNMA,
5.10 for AT+CNMI and 5.16 for AT+CSMS.
· Multiplex protocol: If one instance is set to <da>=1 and <mt>=1, then all other
instances must be configured for <mt>=0.
