"Que Compañia ?" is a useful Android app developed by ocLink that allows users in Argentina and Chile to determine the company of mobile and landline phone numbers. With this app, you can easily identify which of your contacts belong to the same company as you and whether you have free calls with them. Additionally, you can check the company associated with a number before making a call.

The app works in Argentina for all major companies such as Movistar, Personal, Claro, Nextel, Telefonica, and Telecom. In Chile, it supports Entel, Claro, Movistar, Wom, Nextel, and other companies.

In addition to providing the company information, "Que Compañia ?" also informs you about the location and province of incoming calls. The app now includes a feature for number portability, allowing users to inform the app if they have switched companies, thereby increasing the accuracy of the classification.

It is important to note that "Que Compañia ?" does not store any contact information under any circumstances, ensuring the privacy and security of user data.

Please note that this app is only available for use in Argentina and Chile.
