Unstructured Supplementary Service Data
Unstructured Supplementary Service Data, or USSD, is a fancy word for a text message that you can send to your phone company. It's like when you send a text message to your friend, but instead of chatting about fun stuff, you're telling your phone company what to do.
For example, let's say you want to check how much money you have left on your phone plan. You can send a message to your phone company with a special code that tells them to give you that information. You don't need to download any apps or use the internet to do this – all you need is your phone and your phone number.
One cool thing about USSD is that it works on different types of phones, even the old ones that don't have fancy apps or touchscreens. It's also very fast – you don't have to wait for a webpage to load or for an app to launch. The information shows up on your screen right away after you send the message.
Overall, USSD is a quick and easy way to communicate with your phone company and get the information you need without using data or needing a Wi-Fi connection.
