Can I assign specific ringtones to certain contacts

[Cerixy]

Yes, most phones allow you to assign custom sonnerie totally spies to different contacts. Check your phone's guide for how to do this.

Most free ringtones available for download are for personal, non-commercial use. Please check usage rights before commercial use.

To remove a ringtone from your phone, go to your device's audio or sound settings, then select the ringtone you want to remove. Generally, you can press the "Delete" button to do so.
