+CUSD - Unstructured Supplementary Service Data SELINT 0 / 1
Note: the unsolicited result code enabled by parameter <n> is in the
format:
+CUSD: <m>[,<str>,<dcs>] to the TE
where:
<m>:
0 - no further user action required (network initiated USSD-Notify, or no
further information needed after mobile initiated operation).
1 - further user action required (network initiated USSD-Request, or
further information needed after mobile initiated operation)
2 - USSD terminated by the network
3 - other local client has responded
4 - operation not supported
5 - network time out
Note: in case of successful mobile initiated operation, DTA waits the USSD
response from the network and sends it to the DTE before the final result
code. This will block the AT command interface for the period of the
operation.
Note: issuing AT+CUSD<CR> is the same as issuing the Read command.
Note: issuing AT+CUSD=<CR> is the same as issuing the command
AT+CUSD=0<CR>.
AT+CUSD? Read command reports the current value of the parameter <n>
AT+CUSD=? Test command reports the supported values for the parameter <n>
