Welcome!

My nickname is Todd and I will be the expert working with you today to help resolve your problem.

Before we start, please let me explain how this service works:
Electronics troubleshooting is not always easy and sometimes I will not be able to solve your problem immediately, so if my first answer does not solve your problem or you need more information please do not rate my answer bad or negative "Helped a little" or "I expected more". Please use "Reply to Expert" or "Continue conversation" button instead.

When you are satisfied or your problem has been solved, please rate my answer with 3 STARS or higher/Smiley face, as this is the only way I get credited for helping you.

First of all reset your phone:
Press and hold the Sleep/Wake button and the Home button at the same time for at least 25 seconds (until the Apple logo appears).
* Check the picture below - picture - click here

If that doesn't solve your problem, please check this:
Check the ringer switch on the side of the phone to make sure the phone is not set to silent or vibrate mode. Toggling this switch should give you an onscreen indicator of the ring mode. Silent mode is indicated by a bell icon with a line through it.
Check the picture bellow: Picture with instruction

Please let me know if that works (use "Reply to Expert" or "Continue conversation" button). If not, I'll provide you with the next step. Please do not rate my answer before we find solution for your problem.

Thanks!
