In today’s world, smartphones are incredibly popular for browsing the internet, chatting with friends, sharing information, and more. Yet, let’s not forget about regular cell phones, which still have their user base. These basic phones lack the advanced features of smartphones but have a unique function called USSD (Unstructured Supplementary Service Data) method to serve their users.
USSD, or Unstructured Supplementary Service Data, is a simple yet important way to interact with mobile devices. You’ve probably used it when you dialed *numbers# to access certain functions. This method isn’t just for basic cell phones – it also works on modern smartphones. In this post, we’ll explore how USSD functions and its applications across different types of phones, highlighting how it keeps both traditional cell phones and modern smartphones connected and operational.
We’re all familiar with the process of using certain applications – you open your phone’s dial pad, input numbers that begin with an asterisk (*) and end with a (#). These numerical sequences are known as USSD Codes. Once you’ve entered these codes, you follow the provided instructions, often involving pressing specific numbers to access desired services. Examples of these applications include transferring money, banking functions, and purchasing tickets.
However, while we’re acquainted with how to use these services, have you ever wondered how they actually reach us, where they travel to? These services are made possible through GSM technology. This technology, provided by telecommunication companies, enables calling, messaging, and internet usage. The delivery of these services relies on cell towers and the SIM card present in our phones.
