Download the Claro agenda app now and standardize all your contacts very easily. It's simple and fast!

With this app, you can:
- Add Claro's long distance operator code 21, to ensure you don't incur additional costs for other area codes.
- Add DDD to numbers that are without this information to make it easier for every call to be completed, regardless of where you are.
- Preview all changes before they are applied and select which ones you want to keep.
- Return to your original contacts through automatic backups, if you prefer. (as long as the app is not removed).
