Q: phone does not ring during incomming call

Do you have the mute switch engaged? It's the little slider over the volume buttons on the side. If you can see orange, it's engaged. Slide it the other way.

Is the phone silenced? Check the button on the side of the phone above the volume buttons if you see an orange line it is silienced, slide it to the front of the phone and it should correct this.  Also ensure the volume is up.  If you've checked these and still nothing are you able to call people? do you have service?

Happy to help, and Good Luck.

what if the silence button is not in the silence mode and I still am not getting a ring tone or text tone for incoming calls or texts..I have iphone 4S
