If you want to use a custom tonos de llamada that you've downloaded or transferred to your device, tap on the "Add" or "Plus" button (+) usually located at the top-right corner of the screen. This will open your file manager or show a list of compatible apps to choose from.
Browse your file manager or the suggested apps to find the location where your custom ringtone is saved. Once you locate it, tap on it to select it as your ringtone. If necessary, you may need to grant permission for the file manager or app to access your device's storage.
After selecting the desired ringtone, you'll be taken back to the ringtone selection menu. You should now see the new ringtone listed at the top of the available options.
Tap the "Back" or "Done" button to save the changes and set the selected ringtone as your default phone ringtone.
Now, when you receive a call, your chosen ringtone will play. You can repeat these steps to change your ringtone at any time. Keep in mind that the options and menu names may vary slightly depending on the Android version and device manufacturer.
