USSD Codes Shortkeys is an Android application developed by Koni under the Utilities & Tools category. It allows you to configure various settings for your phone by using USSD codes provided by your phone carrier. You can easily access features such as asking for balance, stopping or starting combox/voice box, and loading pre-pay, among many other options. The possible USSD short keys depend on your telephone provider, and sending USSD codes is usually free.

This app is easy to use and navigate, making it a convenient tool for anyone who wants to quickly access their phone settings. If your phone provider is not listed, you can send an email to the developer with the name and country, and they will try to integrate it.
