If You Want To Unlock Hidden Features On Your Phone, You Need To Know About These Secret Codes

Unstructured Supplementary Service Data (USSD) is a technology that allows users to access various services using shortcodes. These codes are usually two to six digits long and are entered into the phone's keypad to unlock hidden features. It is a very convenient way to access services and is often used in areas where network coverage is poor or unreliable.

In recent times, this technology has emerged as a promising marketing tool, with many businesses using USSD codes to send promotional messages to customers.

However, many of us aren't yet familiar with the notorious "secret codes" that can unlock hidden features on our smartphones. These codes are not publicized by the manufacturer and are often used to test new features.

A secret code is a sequence of numbers, letters, or symbols that can be used to unlock hidden features. These features range from changing your ringtone to switching on call forwarding. The process is quite simple - Enter the code into your phone's keypad and press the call button.

Secret codes that will unlock hidden features on your phone

The first thing that you need to do is to input a specific code on your phone. Some of the most popular ones include:

When you enter *#0*# into your phone's keyboard, you'll be taken to the "General Test Mode" screen. This screen provides a variety of tests that you can run on your phone, including tests for the display, buttons, vibration, and more.
If you're not sure whether your phone is currently set to forward calls or not, you can use the *#67# code to check for the same. It will also display the number of your calls that are being forwarded.
Google Play diagnostics: #*#426#*# - This code lets you access Google Play's diagnostic menu. It is instrumental in testing various aspects of the Google Play Store app, including the in-app billing system.
The IMEI (International Mobile Equipment Identity) is a unique number assigned to every mobile phone. It is used to identify valid devices and can be used to block a stolen phone from being used. To display your IMEI on most phones, simply enter *#06# on the keypad of your phone.
If you need to quickly silence your phone, pressing the # key for more than one second will do the trick. If you need to unsilence your phone, simply press the # key again for more than one second.
