iPhone 13 pro voice cuts and the other person can't hear me

Same here. Every time. I thought at first it was only happening on WiFi calling but turned that off and it has continued to happen the last few months. Ridiculous for the price of this thing. I hope I can get them to replace mine as well and my husbands as we got ours at the same time and his does it too.

I BROKE THE CODE!!! At least for me. I finally realized that the "waterproof" case I bought from Amazon covers all the microphone holes so that no one on the other end can hear you except a very muffled voice from you. I took it off, called a friend, problem solved! I tried every suggestion made in this thread before figuring this out. Check your case and see if it's covering your 3 microphone holes. Good luck!

But did you try the phone with no case at all? I did and it solved the problem then I shopped Amazon for a case that had sound holes at all 3 microphones. I haven’t got it yet but at least try the phone with no case on it.

I have had this issue since getting this new iPhone 13 Pro Max about a month back. I have invested enough time with Apple and AT&T support with no luck. They even asked me to reset the phone. Finally I just converted my SIM to eSIM on my phone and took out the physical SIM from my phone and I have tested making FaceTime calls to family using WiFi as well as Data. No voice cuts anymore. Try it and see if it fixes your issue as well.

I had earlier today used Beats headset while making FaceTime calls. That also fixed the voice cuts.

Solutions to this iphone muffling and cut outs when you use your speakerphone have shown several remedies that fixed the problem for some, but not for others. These solutions have fixed this problem so far:

Update the iOS software on your phone to 15.2.1- Look in settings, general, software update.

Replace the SIM with the eSim ( I don't know how to do this)

Remove your case. Some cases block the microphone and speaker holes, especially if you are using a "waterproof" case. (This was my remedy and at least one other person on this thread.)

If there are any other solutions that have worked please reply. And, could somebody explain how to change the SIM to eSIM. Thanks and good luck all.

Also, there are people on this thread that have tried all these remedies and gone to Apple Genious Bars and/or talked to support and there problem was not solved so there may be some defective phones out there but there must be a lot of them and Apple hasn't acknowledged the problem exists yet.

I received a new IPhone 12. I upgraded from an 8. I use the speaker a lot because I need my hands free at times. Mine broke up to the other person so I tried all the things I found online to try. Nothing worked. I went into Verizon and they couldn’t figure it out so they replaced it. The new phone did the same. I was then sent a 12 from Apple and still had the same issue. They finally upgraded it to a 13 and I’m still having the same issue even after spending an hour on the phone with Apple tech support. Can anyone help me solve this issue ?

So. Apple tells me they will send me 3 new phones but I have to pay upfront 1409 per phone and when I mail the old phones back they will credit me. FOH. Told them no way.

Where are the microphones located on them

I have this issue, too. My iPhone is my life line for remote work. Very frustrating to not have use of the speaker phone. Thank you for posting the feedback link. I just submitted my two cents.

Ditto I tried both apple and Verizon. Still paying for a phone that I cannot talk to the most important person in my life my mom

Absolutely

It won’t. I have tried it all.
