In the world of mobile technology, there are numerous codes and shortcuts that can make our lives easier. One such code is the USSD (Unstructured Supplementary Service Data) code, which has been widely used for various purposes. In this article, we will delve into the world of USSD codes, exploring what they are, how they work, and their applications.
What Is A USSD Code?
A USSD code is a string of characters that starts with an asterisk (*) and ends with a hash (#). It is used to communicate with the mobile network operator’s server to perform a specific task or retrieve information. USSD codes are also known as “quick codes” or “feature codes,” and they have been an integral part of mobile technology for decades.
How Do USSD Codes Work?
When you dial a USSD code, your mobile phone sends a request to the network operator’s server. The server then processes the request and sends a response back to your phone. This response can be in the form of a message, a menu, or even a website. USSD codes use the GSM network’s signaling channel to communicate with the server, which means that they do not require an internet connection to work.
Types of USSD Codes
There are two types of USSD codes: network-specific and handset-specific. Network-specific USSD codes are used to access services provided by the network operator, such as checking balance, activating services, or retrieving information. Handset-specific USSD codes, on the other hand, are used to access features and settings on your mobile phone, such as resetting the phone or accessing the engineering menu.
