People Can’t Hear Me on My Phone: What to Do

If the person you’re calling says they can barely hear you — or can’t hear you at all — the issue is usually caused by one of two common problems:

• A dirty or blocked microphone

• Unstable 5G network during calls

Below are the most common causes and how to fix them quickly.

Why Is My Call Quality So Poor?

Many smartphone users assume that the latest networks automatically improve everything, but this is not always the case.

Modern smartphones sometimes use 5G for voice calls, thanks to a technology called VoNR (Voice over New Radio). While this technology is designed to improve call quality, it is still not fully supported everywhere.

When the 5G signal is unstable or the phone struggles to switch between networks, your voice may become very quiet, distorted, or completely inaudible to the person on the other end of the call.

Fix Call Problems by Switching to 4G

One of the simplest solutions is to temporarily disable 5G and force your phone to use 4G for calls.

This works for most Android smartphones and iPhones.

Steps

1. Open your phone settings
Find the Settings app on your home screen.

2. Go to network settings
Depending on your phone, this section may be called:

• Network & Internet

• Connections

• Mobile Network

• SIM & Mobile Networks

3. Change the preferred network type
You may see options like:

• 5G / 4G / 3G / 2G (Auto)

Switch it to:

• 4G only or LTE only

4. Restart your phone if needed
Sometimes restarting helps stabilize the connection.

After switching to 4G, most users immediately notice that call quality returns to normal.

You can try enabling 5G again later, but if the problem comes back, it may be best to keep 4G for calls.

Check if Your Microphone Is Dirty

If you are already using 4G or if your phone is older, the issue may simply be a dirty or blocked microphone.

Smartphone microphones are located in small holes that can easily become clogged with dust, pocket lint, or dirt.

How to clean the microphone

• Look for the small microphone hole at the bottom of the phone

• Blow into it firmly or use compressed air

• You can also use a thin needle or toothpick to gently remove debris

Be careful not to damage the microphone mesh.

Cleaning the microphone often immediately restores normal call volume.

Additional Tips to Improve Call Quality

Check your network coverage
Even with 4G, poor signal coverage can reduce call quality.

Update your smartphone
System updates sometimes fix compatibility problems between phones and mobile networks.

Test with another phone
If the problem persists on multiple devices, the issue may come from your SIM card, carrier, or line.

Summary

If people cannot hear you during phone calls, the issue is usually caused by:

• 5G call instability

• A dirty or blocked microphone

Switching to 4G or cleaning the microphone fixes the problem in most cases.

Even though 5G offers faster mobile internet, voice calls on 5G are still not perfectly supported on all networks and devices.
