Ringer on off

Hi amygrimmer,

Thanks for contacting Apple Support Communities!

We understand that you're unable to hear your alert tones consistently, correct?

Does it appear that the button on the side of your iPhone has been switch off? If so, check out this resource which will show you how to troubleshoot the ringer switch: If a button or switch isn't working on your iPhone or iPad - Apple Support

1. "Remove any protective films or cases that might block the button or switch.
2. Check for debris or dirt around the button or switch and clean with a soft cloth.
3. If the button or switch still isn't working, is damaged, or works intermittently, you can set up a repair."

This is also another great resource to help you troubleshoot your iPhone sound: If you hear no sound or distorted sound from your iPhone, iPad, or iPod touch speaker - Apple Support

We hope this helps you.

Cheers!
