Hidden Call is an Android application developed by Thor Apps that falls under the category of Utilities & Tools. It is a free program that allows users to make a hidden call with ease. The app is designed to be user-friendly and simple to use, with no complex settings or configurations required.

To make a hidden call, users simply need to enter the phone number they wish to call into the app and tap the "Call" button. The app will then automatically add the code #31# before the phone number, ensuring that the call is made anonymously. If the code does not work for your carrier, the app recommends contacting your phone carrier to request the correct code. It is important to note that some phone carriers do not allow this feature.

Overall, Hidden Call is a straightforward and efficient app for those who wish to make anonymous calls. With its easy-to-use interface and the ability to make hidden calls with just a few taps, this app is a great addition to any Android device. If you know a code that works and it's not on the list, the developers are open to feedback and willing to add it to the app.
