USSD (Unstructured Supplementary Service Data) is a Global System for Mobile Communications (GSM) protocol for sending text messages. USSD uses codes made up of characters (up to 182 characters) available on a mobile phone.
​
USSD is similar to Short Message Service (SMS). Still, USSDs are messages that require the user's intervention and interaction, who must know the codes to use to get a specific response/service.
​
If the user is unaware of the USSD code to send for a specific service, they should refer to their mobile carrier or search the web for the desired USSD.
​
This feature is experimental but supported on Proxidize modems in terms of sending/receiving USSD requests/responses, but It will not work in all countries.
​
Users can test sending USSD codes from the Proxidize dashboard by expanding the row of the modem they want to send USSD from > Modem Actions > and Choosing USSD.
​

Once chosen, the user will be given a text box to enter the USSD code for submission:
​

Once the user enters the USSD and hits send, they should receive a response for the code submitted. If you face any issues with sending USSD codes, please contact our support team via the live chat on the website https://proxidize.com.
