When you see "USSD Code Running" on your smartphone, it means that your device is performing a specific function or task using a Unstructured Supplementary Service Data (USSD) code. These codes are a form of protocol used by GSM cellular telephones to communicate with the mobile network operator's computers.
USSD codes can be used for various functions, including checking your phone's balance, requesting specific services (like data plans), or accessing hidden menu options on your device. They're often also used for mobile banking and other financial transactions in countries with low internet penetration.
The message "USSD Code Running" should disappear once the function the code requested has been completed. However, if it doesn't disappear, this may indicate an issue with your mobile network, your phone's software, or the USSD code itself.
