4KÁr is a free Android application developed by Nettools SK. It is not an official app of the Slovak mobile operator 4KA, but it is intended for their customers. The app provides a graphical visualization of consumption items and facilitates the configuration of data and voice services.

The app requires permission to send and read SMS messages for executing SMS commands, and permission to read the phone's status to obtain and select from SIM cards.

The app configuration will be updated according to the current changes in SMS services. If something is not working correctly, or the consumption item is not displayed, please let us know, and we will update the configuration.
