9.14 AT+CUSD Unstructured Supplementary Service Data
AT+CUSD allows to control the handling of Unstructured Supplementary Service Data (USSD) according to 3GPP
TS 22.090 [34]. Both network and mobile initiated operations are supported. The interaction of this command
with other AT commands based on other supplementary services is described in the related technical specifica-
tions.
Parameter <ussdMode> is used to control the presentation of "+CUSD" URCs to the TE, which will be caused by
a USSD response from the network or by different network or USAT initiated operations. Therefore, it is recom-
mended to always have "+CUSD" URCs enabled.
If parameter <ussdReq> is given, a mobile initiated USSD send request or a USSD response to a network or
USAT initiated operation is sent to the network. A possible response USSD of the network is again presented by
a subsequent "+CUSD" URC.
Syntax
