Understanding USSD Code

USSD stands for Unstructured Supplementary Service Data. This protocol is used by GSM cellular phones to communicate with a service provider’s computers.

• Unlike SMS, which is stored and forwarded, USSD messages create a real-time connection, allowing for a two-way exchange of a sequence of data.
• This feature makes USSD ideal for quick communications and real-time interactions.
