1.

Why does my phone not ring when I receive a call or message?

There are several reasons your phone might not ring, including low or muted volume, airplane mode, Do Not Disturb, or a malfunctioning ringtone. Check your volume settings, modes, and ringtone settings to ensure everything is correctly configured.
2.

How do I check and adjust the ringtone volume on my phone?

To adjust the ringtone volume, press the volume up button on your phone, or go to the sound settings in the device menu. Ensure the volume is set high enough and that external volume buttons aren’t accidentally muted.
3.

Can a faulty ringtone cause my phone not to ring?

Yes, if the ringtone file is damaged, too quiet, or incompatible, it can prevent your phone from ringing. Try changing to a default ringtone or re-download the ringtone to fix the issue.
4.

How can I check if the Ring/Silent switch is turned off on my iPhone?

On iPhone, check the physical Ring/Silent switch on the side of your phone. If it shows an orange color, your phone is in silent mode. On newer models, you may need to press the Action Button to toggle between ring and silent modes.
5.

Why does my phone still not ring even when the Do Not Disturb mode is off?

If your phone is still not ringing despite turning off Do Not Disturb, check if your phone is in Airplane mode or if Call Forwarding is enabled. Also, ensure your phone isn’t connected to any Bluetooth devices or external audio sources.
6.

What should I do if my phone keeps transferring calls to voicemail?

Ensure that Call Forwarding is turned off. Check your phone’s settings for forwarding options, and disable it. Also, verify if your network connection is stable, as weak signals can sometimes lead to missed calls.
