Why is my new iPhone 6 garbling my calls, I can't hear incoming and they can only hear choppy talk?

[iMore Question]

I just got this phone and don't know if I have something wrong in the settings or what. The calls are cutting in and out, phone worked fine yesterday. Any help would be appreciated.

Welcome to iMore! A few suggestions. Try these in order:
1. Try resetting your device by holding the power button and home button down simultaneously until you see the Apple boot logo.
2. Go to Settings > General > Reset > Reset Network Settings. Keep in mind you'll have to re-enter any stored wifi passwords.
3. Restore your device, preferably through iTunes.
4. Contact your carrier to make sure there isn't a technical glitch on their end.
5. Bring your iPhone into an Apple Store or contact Apple Support.
