5.4.3 Send USSD
Click [Send USSD] to access the webpage (as shown below) to send USSD commands.
The procedures to send an USSD command are:
a) Select the Line (GSM channel) that you want to send an USSD command to the service provider.
The line status and the SIM (GSM) number are displayed. The last option "All Lines" means that all
channels are selected and the same USSD command is sent via all channels provided that they are in
the “LOGIN” Status.
b) Enter the USSD command
c) Click [Send].
Example:
For the service provider PCCW in Hong Kong, the USSD command to check balance is ##122#. Enter
“##122#” and the click [Start]. The following screen is then displayed.
A few seconds later, the service provider sends back a USSD message/response as shown below.
