people cant hear me on calls on iphone x

I replaced the sim with a new one. No, didn't make a difference for me.

Didn't help me I'm afraid sweetmud. Makes no difference to my phone. Glad it helped you tho

And how can one verify if my IPhone is one of those?

I spent over an hour chatting with Apple support and they remotely went into the phone and said all the hardware is fine but I don’t know ...

Apple replace iPhones. This is a multi billion dollar company. That’s how they made their money. They only want what’s best for them. Money and that don’t include replacing faulty items!!

Yes, you are right ! if they do not do anything with this problem I will have to buy Samsung😠

This did not work for my iPhone X. Callers continue to tell me my voice is muffled or they can't understand me. Even my spouse with his new iPhone X.

Where do you locate the model number?

I bought silver iPhone X (GSM model for ATT) for my son. It is interesting that there are no problem with sound quality. But my black iPhone has problems. The both iPhones have the same model A1901.

This is very interesting, I am waiting on my third phone arriving today and had to accept silver as there were no space grey left (my last were space grey). Maybe it's as well. I'll soon find out!

I hope that everything will be good ! it will be very interesting to know the result.

I have a silver version and have this problem. I don’t think it matters but fingers crossed the replacement will work for you.

It sounds as if some carriers may have issues.

I have an X and am on AT&T and my calls are completely clear.

Think I might do the same, Iv had mine checked but still can not hear me , but it’s not every time, just now and then hen

"here' as in... hey I think we have a problem here. 😂

Uuugh I’m having the same issue!!! What a joke! If I’m moving no one can hear me, everyone says I’m muffled... waste of money! I want my old phone back...
