Missing important calls because your iPhone 16 Pro stays silent is a real headache. You see the missed call notification pop up, but you never heard a thing, even though you're sure the phone should be ringing. Let's get straight to the most common fix for this on your specific model.
First, check your Action Button. The iPhone 16 Pro uses this button, not a physical switch, to control silent mode. Press and hold it until you feel a haptic tap and see a notification in the Dynamic Island. If it says "Silent Mode On," press and hold it again to switch back to ring mode.
You can customize what the Action Button does in Settings > Action Button. Swipe left or right to choose different functions, but make sure it's not set to something other than Silent Mode if you want the classic toggle behavior.
Check Your Focus Modes
Focus modes in iOS 26, like Do Not Disturb or Sleep, are designed to silence interruptions. If one is active, calls won't ring. Swipe down from the top-right corner to open Control Center and look for a highlighted moon or another Focus icon.
Tap the icon to turn the active Focus off. For a deeper check, go to Settings > Focus. Here, you'll see all your configured modes like Work, Personal, and Do Not Disturb.
Make sure each one is toggled off. Also, check the "Turn On Automatically" schedules underneath each Focus to ensure your phone isn't silencing itself based on your location or time of day.
Adjust Your Ringer Volume
Your ringer volume might just be turned all the way down. With your phone unlocked, press the volume up button on the side a few times. You should see the volume indicator on screen and hear a sample sound if your phone isn't in silent mode.
You can also set it precisely. Go to Settings > Sounds & Haptics and drag the "Ringer and Alerts" slider to the right. I'd test it right after by having a friend call you.
Review Your Ringtone and Alert Settings
Sometimes, a corrupted or custom ringtone file can cause issues. Try switching to a different, built-in ringtone. Head to Settings > Sounds & Haptics > Ringtone and pick a new one, like "Reflection" or "Opening."
While you're there, ensure "Change with Buttons" is turned off if you want your ringer volume separate from your media volume. This prevents the side buttons from accidentally lowering your ringer when you're watching a video.
Disconnect Bluetooth Accessories
If your iPhone 16 Pro is connected to AirPods, a CarPlay system, or a Bluetooth speaker, incoming calls will often route audio to that device. Your phone itself will stay quiet.
Open Control Center and tap the Bluetooth icon to turn it off temporarily, or go to Settings > Bluetooth and toggle it off. Test a call with Bluetooth disabled to see if that's the culprit.
Investigate Call Blocking and Filtering
Your phone has several features that can silently filter calls. First, check for blocked numbers. Go to Settings > Phone > Blocked Contacts to see if the caller was accidentally added there.
Next, look at "Silence Unknown Callers" in the same Phone settings menu. When this is on, any number not in your contacts, Mail, or Messages goes straight to voicemail without a ring. Toggle it off if you're expecting calls from new numbers.
Also, check Settings > Phone > Call Forwarding. If this is accidentally enabled and set to another number, your iPhone 16 Pro won't ring because calls are being sent elsewhere.
Perform a Force Restart
A quick force restart can clear out temporary software glitches affecting the ringer. On the iPhone 16 Pro, you press and quickly release the Volume Up button, then press and quickly release the Volume Down button.
Immediately after, press and hold the Side button. Keep holding it until you see the Apple logo appear, then release. This sequence is based on the iPhone 15 Pro and is the expected method for your model.
Update to the Latest iOS 26 Version
Apple frequently releases software updates that fix bugs, including audio and notification issues. Make sure your iPhone 16 Pro is running the latest version of iOS 26.
Connect to Wi-Fi and plug in your charger. Go to Settings > General > Software Update. If an update is available, tap "Download and Install." Keeping software current is one of the best ways to prevent these kinds of problems.
Reset All Settings
If the problem persists, a settings reset can help. This won't delete your photos, apps, or personal data, but it will revert all your preferences back to defaults. Things like Wi-Fi passwords and wallpaper will need to be set up again.
Go to Settings > General > Transfer or Reset iPhone > Reset. Then, tap "Reset All Settings." You'll need to enter your passcode to confirm. After the phone restarts, check if your ringer works.
Check App-Specific Calling Issues
If your iPhone rings for regular calls but not for calls from apps like WhatsApp, FaceTime, or Skype, the issue is likely with that specific app. First, head to the App Store and make sure the app is updated to its latest version.
Then, check the app's notification permissions. Go to Settings > [App Name] > Notifications. Ensure notifications are allowed and that the sound setting is turned on. Sometimes switching from cellular data to a strong Wi-Fi connection can also improve VoIP call reliability.
Reset Network Settings
For ongoing issues with call connectivity or app-based calls not ringing, resetting network settings can be a useful step. This clears all network-related data, including Wi-Fi networks, passwords, cellular settings, and VPN configurations.
Navigate to Settings > General > Transfer or Reset iPhone > Reset. This time, select "Reset Network Settings." Confirm your passcode, and your phone will restart. You'll then need to rejoin your Wi-Fi networks.
