Vivo mobile phone comes with ringtones.

If you mean how to set the system's own ringtone:

Enter the settings-sound and vibration/sound, vibration and silent key/sound-and you can set the incoming call ringtone, information ringtone, calendar reminder ringtone, notification ringtone, alarm ringtone and so on.

Custom ringtone setting method:

1. Go to Settings-Sound and Vibration/Sound, Vibration and Silent Keys/Sound-Call Ring-Customize the call ring, and select a local song, or click the clip in the upper right corner after selecting a song, and freely intercept the song fragment and set it as the call ring.

2. Enter the music, select a song in the music playlist-click "..."-select ringtone-after clipping-set it as ringtone. At present, ringtone making formats are supported: MP3 and WAV, but setting ringtones is not supported for paid or member songs (the ringtones made are saved in the "Making ringtones" folder in file management).
