How USSD works

• USSD (Unstructured Supplementary Service Data) enables mobile phone users to send and receive information in real time. Allow me to explain how it works in detail.
• A mobile phone user sends a request: They wish to see their bank account balance. They submit a request by entering a specific code (typically five numbers) into their phone.
• The request is transmitted to a system known as the USSD gateway.
• USSD Gateway forwards the request: The gateway transmits the request to the appropriate USSD application. For example, the bank's application for checking account balances.
• USSD Application Responds: The USSD application processes the request and generates a response.
• The answer from the USSD application is sent back to the USSD gateway.
• The USSD gateway delivers the response back to the user's mobile phone and displays it on the screen.

How Do USSD Codes Differ From SMS Services?

If you assume USSD codes and SMS services are the same, you are incorrect. Both are really different. The USSD codes originate from the real-time connection. When you enter the USSD code into your device, the communication channel opens up. It allows two-way communication. As a result, it is more responsive than traditional SMS platforms.

Differences in USSD, MMI, and SS Codes

Man-Machine Interface (MMI) Codes

MMI codes are unique codes that users type into their mobile phones using the keypad and include * or # characters. These codes can perform a variety of functions and are divided into several categories:

Supplementary Service Codes (SS)

• Goal: Manage call forwarding and number presentation.
• Example: 21987654321# . This code instructs the phone to ask the network to redirect all incoming calls to the number 987654321.
• How It Works: The phone reads the code and creates a request to the network.
• Characteristics: These codes are hardcoded into all GSM, UMTS, and LTE devices and cannot be modified by network providers.

USSD Codes

• Purpose: Allow real-time communication between the phone and the network.
• To check the balance of a prepaid card, enter *#100# .
  
• How It Works: If the code ends in # and is not recognized by the phone's MMI interpreter, it is sent to the network for processing.
• Characteristics: The network determines which codes to support.

Manufacturer-defined MMI codes

• Purpose: Activate service menus or reset devices for particular phone models.
• For example, dialing *#06# will reveal the device's International Mobile Equipment Identity (IMEI).
• How It Works: These codes run as soon as the last digit or character is input, without the need to push .
  
• Characteristics: Not communicated to the network and unique to the manufacturer.

Conclusion

Thus, having a comprehensive list of USSD codes for major Indian telecom networks like as Airtel, BSNL, Vi, and Jio is really important. These codes enable consumers to easily access critical information about their mobile services, check their balances, discover new deals, and handle other mobile features.
