Tablet not ringing when calls? Here's why and how to fix

Modern tablets with SIM card support blur the line between smartphones and larger productivity devices. They allow users to make and receive calls, send messages, and stay connected without relying solely on Wi-Fi. But when your tablet suddenly stops ringing during incoming calls, it can be both confusing and frustrating—especially if you depend on it as your primary communication device. Unlike smartphones, tablets often have additional layers of settings, software quirks, and hardware variations that can complicate troubleshooting.

This issue doesn’t always point to a single cause. In many cases, it’s a combination of misconfigured settings, software glitches, or network-related problems. The good news is that most of these causes are relatively easy to identify and fix once you understand where to look. This guide walks you through the most common reasons your tablet isn’t ringing and provides clear, practical solutions to restore normal functionality.

1. Silent Mode or Do Not Disturb Is Enabled

One of the most common reasons your tablet isn’t ringing is that it’s set to silent mode or has Do Not Disturb (DND) turned on.

What happens:

• Incoming calls arrive, but there’s no sound.
• You may see missed call notifications afterward.

How to fix it:

• Check your volume settings and increase the ringtone volume.
• Turn off silent mode or vibration-only mode.
• Go into your device settings and disable Do Not Disturb, or adjust it to allow calls from all contacts.

Some tablets allow exceptions (like favorite contacts), so ensure your settings aren’t filtering calls unintentionally.

2. Ringtone Settings Are Misconfigured

If your ringtone is set to “None” or a very low volume, your tablet won’t produce any sound for incoming calls.

What to check:

• Navigate to sound settings.
• Confirm a ringtone is selected.
• Ensure the volume slider for calls is turned up.

Pro tip:
Try switching to a default ringtone to rule out issues with custom audio files, which may sometimes fail to play.

3. Call Forwarding or Call Blocking

If calls are being forwarded or blocked, your tablet won’t ring at all.

Possible scenarios:

• Calls are redirected to another number.
• Specific contacts are blocked.
• Unknown callers are silenced automatically.

Solution:

• Check call forwarding settings and disable them if unnecessary.
• Review your blocked numbers list.
• Turn off features like “Block unknown callers” if you want all calls to come through.

4. Network or SIM Card Issues

Since SIM-enabled tablets rely on cellular networks, any issue with the SIM card or carrier connection can prevent calls from ringing.

Signs of trouble:

• No signal or weak reception.
• “No Service” or “Emergency Calls Only” message.
• Calls go straight to voicemail.

Steps to fix:

• Restart your tablet.
• Remove and reinsert the SIM card.
• Check if the SIM card works in another device.
• Contact your carrier to confirm your line is active and supports voice calls.

Not all tablet SIM plans include voice services, so it’s worth verifying your subscription.

5. App Conflicts or Third-Party Interference

Certain apps—especially call management, security, or automation apps—can interfere with incoming call notifications.

Examples include:

• Call screening apps
• Battery-saving apps
• Third-party dialers

How to resolve:

• Boot your tablet in safe mode to disable third-party apps temporarily.
• If calls ring normally in safe mode, uninstall recently added apps one by one.
• Check app permissions to ensure your default phone app has full access.

6. Software Glitches or Outdated System

Software bugs can occasionally disrupt basic functions like call notifications.

Symptoms:

• Calls intermittently fail to ring.
• Notification sounds behave inconsistently.

Fixes:

• Check for system updates and install the latest version.
• Restart your device regularly.
• Clear cache for the phone or dialer app.

If the issue started after an update, a future patch may resolve it.

7. Bluetooth or Connected Devices

If your tablet is connected to Bluetooth headphones, speakers, or a car system, the ringtone may be routed there instead of the tablet’s speakers.

What to do:

• Turn off Bluetooth temporarily and test incoming calls.
• Check connected devices and disconnect unused ones.
• Adjust audio output settings if your tablet allows it.

8. Hardware Problems

If none of the software fixes work, the issue could be hardware-related.

Possible causes:

• Faulty speakers
• Internal damage
• Manufacturing defects

How to check:

• Play music or videos to test the speaker.
• Use headphones to see if sound works there.
• Run built-in diagnostic tools if available.

If the speaker isn’t working at all, professional repair may be required.

9. Notification Settings Are Disabled

Some tablets allow fine control over notifications, including call alerts.

Check the following:

• Notification permissions for the phone app
• Sound settings for incoming calls
• System-wide notification controls

Make sure calls are allowed to produce sound and appear on screen.

10. Carrier Restrictions or VoLTE Settings

Some carriers require VoLTE (Voice over LTE) to be enabled for calls to function properly on tablets.

Solution:

• Go to mobile network settings.
• Enable VoLTE if available.
• Contact your carrier to confirm compatibility.

Final Thoughts

When your tablet stops ringing for incoming calls, it’s easy to assume the worst—but in most cases, the issue is tied to a simple setting or temporary glitch. By systematically checking sound settings, network connections, and app behavior, you can usually pinpoint the cause without needing technical expertise. The key is to approach the problem step by step rather than making random changes that may complicate things further.

Ultimately, SIM-enabled tablets are powerful communication tools, but they also come with added complexity compared to traditional smartphones. Staying familiar with your device’s settings and keeping your system updated can prevent many of these issues from occurring in the first place. If all else fails, reaching out to your carrier or a professional technician can help ensure your tablet returns to full functionality without missing another important call.
