How to Fix Signal Not Ringing for Calls
If you've ever missed a call on Signal because your phone didn’t ring, you’re not alone. Signal is fantastic for private messaging and calls, but sometimes the app’s call notifications can be a bit finicky. In this guide, I’ll walk you through practical, real-world steps to fix Signal not ringing for calls — from checking your phone settings to some lesser-known Signal features that might be affecting your calls.
Why Is Signal Not Ringing for Calls?
Before diving into fixes, it’s helpful to understand what might cause Signal not to ring. Signal uses end-to-end encryption and works differently from regular phone calls or even other VoIP apps. This means:
- Call notifications rely on push notifications from Signal’s servers.
- Your phone's notification settings and battery optimization can interfere with timely alerts.
- Signal has its own permissions and settings that can mute or silence calls.
With that in mind, the problem usually boils down to either notification settings, permissions, or battery management quirks on your device.
Step-by-Step Fixes for Signal Not Ringing for Calls
1. Check Signal’s Notification Settings
This is the first place I always look when Signal calls aren’t ringing:
- Open Signal and tap your profile icon in the top left.
- Go to Settings > Notifications.
- Make sure Calls notifications are enabled.
- Tap on Calls and verify that the sound is set (not “None” or “Silent”).
- If you see a “Vibrate” option, you can toggle that on or off depending on your preference.
Sometimes, you might have muted calls accidentally or set a custom “Do Not Disturb” mode in Signal itself — so keep an eye out for that.
2. Verify Your Phone’s System Notification Settings
Signal depends on your phone’s notification system, so it’s important that your device isn’t blocking Signal calls:
- Go to your phone’s Settings > Apps & Notifications > Signal (the path varies slightly by Android or iOS).
- Tap Notifications.
- Look for the Incoming calls category.
- Ensure notifications are enabled with sound and priority set to “High” or “Urgent” so the call can break through Do Not Disturb modes.
On Android, you may also want to check App notifications > Advanced and allow Override Do Not Disturb. This is crucial if you use DND often.
3. Disable Battery Optimization for Signal
This is a classic culprit for delayed or missing Signal call rings. Many phones aggressively limit background activity for apps to save battery:
- Open your phone’s Settings.
- Search for Battery Optimization or Battery Saver (varies by device).
- Find Signal in the list and set it to Not optimized or Unrestricted.
On my Android phone, once I disabled battery optimization for Signal, my calls started ringing reliably again — no more missed calls just because my phone was “sleeping” the app.
4. Double-Check Permissions
Signal needs a handful of permissions to alert you properly:
- Microphone - for calls themselves.
- Phone or Call Logs - sometimes needed for call handling on some Android versions.
- Notifications - obviously critical.
Go to Settings > Apps > Signal > Permissions and confirm all relevant permissions are granted. If anything is denied, the app can behave unpredictably.
5. Inspect Signal’s Do Not Disturb and Mute Features
Signal has a built-in “mute” feature for chats and calls, which sometimes trips people up:
- Open Signal and check if you accidentally muted calls or notifications globally (some people do this for “quiet hours”).
- On Android, long-press on a conversation and check if it’s muted — though this mainly affects messages, not calls.
- Also verify if Focus Mode or Digital Wellbeing settings on your phone are silencing Signal.
6. Keep Signal Updated
Signal’s developers are constantly improving call features (check signal.org for updates and release notes). Running an outdated version can mean you miss out on bug fixes and improvements.
Head to the Google Play Store or Apple App Store and update Signal if you haven’t in a while.
Bonus Tips and Quirks From Years Using Signal
After years of using Signal daily, here are a few things I learned that might help:
- Try toggling Airplane Mode: If Signal calls aren’t ringing, sometimes just turning Airplane Mode on and off resets network connections and clears notification hiccups.
- Reboot your phone: It’s old advice but often works wonders. Sometimes the system notification service or Signal’s background process can get stuck.
- Check for conflicts with other apps: Some Android phones have aggressive “security” or “cleaner” apps that kill background processes. If you use one, whitelist Signal.
- Use Signal’s test call: You can call a friend or your own other device on Signal to see if ringing works, instead of waiting for a “real” call.
Conclusion: Getting Your Signal Calls Ringing Again
If you’ve followed these steps, you should be well on your way to fixing Signal not ringing for calls. Just remember — because Signal uses encrypted push notifications, it depends heavily on your phone’s notification system and background app management. That means the fix often lies outside Signal itself, in your phone’s settings.
