How to Fix Signal Call Disconnecting
If you’ve ever been in the middle of an important conversation on Signal only to have the call drop unexpectedly, you know how frustrating it can be. Signal calls disconnecting can happen for a variety of reasons, but don’t worry—there are several practical ways to troubleshoot and fix this issue. As someone who uses Signal daily, I’ve gathered some tips and tricks that go beyond the basics to keep your calls steady and secure.
Understanding Why Signal Calls Disconnect
Before jumping into fixes, it’s helpful to understand why Signal calls disconnect in the first place. Signal uses your internet connection—Wi-Fi or cellular data—to route encrypted calls. So, any hiccup in connectivity usually affects call stability. But there’s more to it:
- Network fluctuations: Weak or unstable Wi-Fi or mobile data connections can cause call drops.
- App permissions: If Signal can’t access your microphone or network properly, calls might fail.
- Battery optimization: Some Android devices aggressively limit background activity, which can interfere with ongoing calls.
- Outdated app version: Bugs in older versions can cause unexpected behavior.
- Device-specific quirks: Some phones have unique network handling that can affect VoIP calls like Signal’s.
Now that we’ve got the basics covered, let’s get into how to fix Signal call disconnecting issues step-by-step.
Step-by-Step Fixes for Signal Call Disconnecting
1. Check Your Internet Connection
This sounds obvious, but it’s amazing how often a flaky connection is the culprit. Here’s what I do:
- Switch between Wi-Fi and cellular data: If you’re on Wi-Fi, try toggling to mobile data or vice versa to see if that stabilizes the call.
- Restart your router: Sometimes the router just needs a quick reboot to fix temporary slowdowns or connection drops.
- Run a speed test: Use apps like Speedtest to confirm your connection speed and ping. Signal needs a stable connection, particularly upload speed, for smooth calls.
If you notice your internet is dipping under 1 Mbps during calls, that could explain the disconnects.
2. Update Signal to the Latest Version
Signal is constantly improving its call handling and security, so keeping the app updated is crucial. Here’s how:
- Open your device’s app store (Google Play or Apple App Store).
- Search for “Signal Private Messenger.”
- If an update is available, tap Update.
- Restart the app after updating.
Updated versions often fix bugs that might cause calls to disconnect unexpectedly.
3. Adjust Battery and Data Saver Settings
On Android devices, aggressive battery optimization can cut off Signal’s background processes during calls. This is a sneaky cause of call drops that’s easy to overlook.
To fix this:
- Go to Settings > Battery or Battery Optimization.
- Find Signal in the list of apps.
- Select Don’t optimize (or equivalent option) to allow Signal to run freely in the background.
- Also, check if your device has a Data Saver mode and whitelist Signal.
On iPhone, this is less common but make sure Low Power Mode isn’t enabled during important calls.
4. Verify Signal’s Permissions
Signal needs access to your microphone and network to make calls. If these permissions are restricted, calls may drop or fail to connect properly.
Here’s how to double-check:
- On Android, go to Settings > Apps > Signal > Permissions.
- Make sure the Microphone and Phone (if available) permissions are granted.
- On iPhone, open Settings > Signal and ensure Microphone and Cellular Data are enabled.
5. Restart Your Phone (Surprisingly Effective)
Sometimes the simplest trick works best. Restarting your phone clears temporary glitches that might interfere with network or app performance. I find this especially helpful if Signal calls disconnect consistently after the phone has been on for a long time.
Bonus Tips from a Regular Signal User
After using Signal daily, here are a few extra things I’ve learned that might help you fix Signal call disconnecting issues:
- Use Wi-Fi Calling as a backup: If your carrier supports Wi-Fi Calling, enabling it can improve call stability when cellular signals are weak.
- Close other heavy apps: Running lots of apps or downloads in the background can throttle network resources Signal needs for calls.
- Test calls with different contacts: Sometimes the issue may be on the other person’s end or their network.
- Clear Signal’s cache (Android only): Go to Settings > Apps > Signal > Storage > Clear cache. This can resolve weird glitches without deleting your messages.
- Try Signal on desktop: If your phone keeps disconnecting calls, using the Signal desktop app (available at signal.org) can be a good backup option.
