Orange 10 is a free Android application developed by Orange Côte d'Ivoire S.A. It falls under the category of Business & Productivity and aims to simplify the process of changing contact prefixes based on the mobile network operator. With just a few clicks, this app takes care of the task, eliminating the need to manually update each contact.

The application automatically adds the appropriate prefix to fixed-line phone numbers. For example, it adds "21" for Moov network lines, "25" for Mtn network lines, and "27" for Orange network lines. Similarly, when it comes to mobile phone numbers, the app adds the correct prefix: "01" for Moov SIM cards, "05" for Mtn SIM cards, and "07" for Orange SIM cards.

Orange 10 also offers the flexibility to switch your contact list from 8-digit to 10-digit format and vice versa. Additionally, you can choose to exclude specific contacts from the conversion process by selecting the button at the top right. The app provides a progress tracker, allowing you to monitor the conversion status of your contacts.
