I no longer have a ringtone sound for incoming calls or alerts. I can make calls and talk and here my party but no ringtone.

Hi @Jane DeLoge On the Home screen, click the Sounds icon. Verify that your sound profile is not set to either All Alerts Off or Silent. If you have assigned a ring tone or alert to a specific contact, on the Home screen, click the Sounds icon. Click Set Contact Alerts. Click the contact alert. Click Phone or Messages. Verify that the Volume field is not set to Silent and the Vibration field is not set to Off.

Try plugging some headphones in and out to see if that helps do this multiple times will having music playing. Then try calling out and have someone call you to see if it resets it self.
