My iPhone does not ring when I get a phone call

Hi edieb576,

to put your iPhone in Ring mode, move the switch so that orange isn't being displayed.

Here you can read the complete guide How to put your iPhone on vibrate, ring or silent mode – Apple Support (UK)

Let me know if this solves the problem for you!

Then you have the Mute switch turned on. Switch it in the other direction. See this for use of the Mute switch. How to put your iPhone on vibrate, ring, or silent mode - Apple Support

hopefully that helps. If not, go to Apple support and you might find your answer there.
