When I use my microphone for a phone call, I can hear fine but people can not hear me and I have to disconnect my microphone to communicate

Hi sharda128,

Thanks for reaching out to Apple Support Communities.

It sounds like you’re having an issue with people hearing you on your iPhone.

We’re happy to assist.

We recommend checking out the steps from the article here: If you hear no sound or distorted sound from your iPhone, iPad, or iPod touch speaker - Apple Support

Follow these steps

1) If your device has a Ring/Silent switch, move the switch forward—toward the device's display—so that orange isn't showing. If you're using an iPad, you can also swipe down from the top-right corner to open Control Center and make sure that Silent Mode is off. 

2) Open Settings > Focus > Do Not Disturb and make sure that Do Not Disturb is off.

If you want to try more steps on your own

If you prefer, here are some more steps you can try on your own. After following these steps, you might still need to contact Apple Support to discuss service options.

1) Remove all screen protectors, films, or cases from your device. 

2) Check the speaker opening to see if it's blocked or dirty. On iPhone only, make sure that the receiver isn't blocked or dirty. 

3) If necessary, clean the speaker or receiver opening with a small, soft-bristled brush. Make sure that the brush is clean and dry.

4) Go to Settings > Sounds (or Settings > Sounds & Haptics), and drag the Ringer and Alerts slider back and forth a few times. If you don't hear any sound, or if your speaker button on the Ringer and Alerts slider is dimmed, your speaker might need service.

5) If you hear sound, try making a call with your iPhone and turn on speakerphone. On iPad or iPod touch, make a FaceTime call. If you still can't hear, or hear static or crackling, then your network or reception could be the issue. Try to call again later, or from a different location.

The reason why we are recommending the steps above is because they will show you what to do if you can't hear a person's voice clearly, hear crackling, hear static, or have issues with sound quality on your iPhone.

Should the issue continue, follow-up with the steps in this article: If the microphones on your iPhone aren't working - Apple Support

Please let us know the outcome after giving the above steps a try.

Cheers!
