How USSD Works
USSD (Unstructured Supplementary Service Data) is a way for mobile phone users to send and receive information in real time. Let me explain how it works in detail:
User Sends a Request: A mobile phone user wants to do something like check their bank account balance. They send a request by dialing a special code (usually five numbers) on their phone.
Request Goes to USSD Gateway: The request is sent to a system called the USSD gateway.
USSD Gateway Forwards the Request: The gateway sends the request to the specific USSD application that can handle it. For example, the bank’s application that checks account balances.
USSD Application Responds: The USSD application processes the request and prepares a response.
Response Goes Back to Gateway: The response from the USSD application is sent back to the USSD gateway.
Gateway Displays Response: The USSD gateway sends the response back to the user’s mobile phone, where it is displayed on the screen.
Differences Between USSD, MMI, and SS Codes
Man-Machine Interface (MMI) Codes
MMI codes are special codes that users enter on their mobile phones using the keypad, which include * or # characters. These codes can perform various functions and are classified into different groups:
- Supplementary Service (SS) Codes
- Purpose: Control call forwarding and number presentation.
- Example: 21987654321# <SEND> – This code tells the phone to ask the network to forward all incoming calls to the number 987654321.
- How It Works: The phone interprets the code and constructs a request to the network.
- Characteristics: These codes are hardcoded into every GSM, UMTS, and LTE device and cannot be changed by network operators.
- USSD Codes
- Purpose: Enable real-time communication between the phone and the network.
- Example: *#100# <SEND> – Commonly used to check prepaid card balances.
- How It Works: If the code ends in # and is not recognized by the phone’s MMI interpreter, it is sent to the network to be processed.
- Characteristics: The network decides which codes to support.
- Manufacturer-Defined MMI Codes
- Purpose: Activate service menus or reset devices, specific to phone models.
- Example: *#06# – Displays the device’s International Mobile Equipment Identity (IMEI).
- How It Works: These codes are executed as soon as the last digit or character is entered, without needing to press <SEND>.
- Characteristics: Not sent to the network and are specific to the manufacture.
