What Are STC SIM Codes
STC SIM codes are short dial codes that you type into your phone like a phone call. These codes are called USSD codes. They start with an asterisk (*) and end with a hash (#).
When you dial one of these codes, your phone connects directly to STC system without needing the internet or an app. The system reads your code and sends you back the information you requested.
Here is why this is so useful. First, these codes work on any phone, old or new. Second, you need no internet connection. Third, you get your answer instantly. No waiting on hold with customer service. Just instant information.
