Contato Certo

Update your contacts quickly and conveniently

This app is designed for those who have switched carriers or whose contacts are out of date for making calls nationwide (Brazil).
Your contacts will be updated by adding:
- Your area code, if necessary;
- The ninth digit (9), if necessary;
- Your country code (Brazil) (+55), if necessary.
The carrier code (CSP), if applicable, will also be removed.
