When making or receiving a call I can hear the person but they cannot hear me?

When making or receiving a call I can hear the person perfectly but they cannot hear me or the sound quality is too bad for them to understand what I say. My mic works because calling via internet (facebook) the call works perfectly in both ways. Any ideas? I removed the sim Card, updated my iPhone, restarted it.

Try calling through Whatsapp, Facebook Messenger, Skype or any other Internet Calling, this will check if the problem is with Fizz phone calling system or your mobile.
As these apps uses internet to call, they will not use Fizz... you can try even without the simcard inserted using some WiFi Internet.

Where are you residing, maybe a weak signal?

Your iPhone has multiple microphones. It may be that the mic for phone calls is defective.

 

You can try some troubleshooting to narrow down the issue:

- Try calling with (and without) speakerphone to see if there is any change.

- Also try calling with a headset (with bult-in microphone).

Very weird, does it work when you put it on speaker? Or with hands-free?

Move your sim to another phone and give it a try.My guess is that there is some dirt accumulated in Iphone microphone.

Ok I tried with with earbuds with integrated mic and it works perfectly and it also works well when I am on speaker phone. So still not sure how to fix this but at least I know it is not because of FIZZ network but probably because of my crappy iphone 6.
Thank you for your help guys!
