My New iPhone 5 Has No Sound?

My iPhone 5 has sound through the speaker when I use Siri or review ringtones. This was a NEW iPhone 5 for Christmas and it has the iOS update 6.0.2. I have the volume all the way up, Sounds are on and my phone will not play a ringtone when I receive a text message or a call. My sister and my brother's iPhone 5's do, but not mine. It can't be the settings for I reset my iPhone's settings. I will PERFECTLY hear Siri or when I click on a ringtone to choose it. But everything else like lock sounds, keyboard sounds and tones when I receive a message or a call will not play. Volume is max, sound setting is on and still nothing. If anybody have a fix for this please let me know.

Call your co pant an tell them and ask to exchange it. My 20 year old sister had the same problem with her new iPhone 5 and she called for a new one and it arrived yesterday. Seriously something is wrong with these new iPhones. So ya just call then & they'll know what you're taking about its been happening to alot of people with the iPhone 5. My sister got hers defective. So it's not like your the only one. Hope this helped!

You may already know this, but there's a switch on the side of the iPhone. On the left side. It disables all alert sounds (such as texts, calls, etc.). That is probably the problem. If it is not, you should call Apple (the phone is still under warranty) and tell them your issue.

I agree with BDDEC97 you need to check the switch on the side of the iPhone and if it is not then you should go to the Apple Center and tell them what's wrong with your iPhone 5.

Bddec97 is correct. I couldn't figure out why I had no sound either than checked out the side switch and it was turned off. Mine's all fixed now.
