People can't hear you ? This article explains the main causes and the best solutions !

1. 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.

2. 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.

3. Fix Call Problems by Switching to 4G

If you experience poor call quality, dropped calls, or call connection issues, one of the easiest solutions is to temporarily disable 5G and force your phone to use 4G (LTE) for mobile communications. This method works on most Android smartphones and iPhones and can often restore stable calling performance immediately.

To do this, open the Settings app on your phone and navigate to the mobile network settings. Depending on your device, this section may be called Network & Internet, Connections, Mobile Network, or SIM & Mobile Networks. Look for the Preferred Network Type option and change it from 5G/4G/3G/2G (Auto) to 4G Only or LTE Only. If necessary, restart your phone to help stabilize the connection. After switching to 4G, many users notice an immediate improvement in call quality and network reliability. You can try re-enabling 5G later, but if the issue returns, keeping 4G for calls may provide the most consistent experience.

If the problem persists, reset the phone network settings or reset your phone.

4. 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.

5. 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.

Conclusion

If people cannot hear you during phone calls, the problem is often linked to 5G call instability or a dirty, blocked, or damaged microphone. In many cases, a simple switch from 5G to 4G (LTE) can immediately improve call quality and restore clear voice transmission. Likewise, carefully cleaning the microphone opening can remove dust or debris that may be affecting sound pickup.

Although 5G provides faster mobile internet speeds, voice calling technology is not yet perfectly optimized on all networks and devices. As a result, some users may experience poor call quality, audio cutouts, or situations where the other person cannot hear them properly. If these issues occur regularly, using 4G for calls may offer a more stable and reliable experience.
