Problem

Signal won’t send or receive messages, calls won’t connect, or the app shows “Connecting…” even though your phone has internet access.

---

Solution

Connection issues are usually caused by unstable internet, restrictive network settings, or app-level restrictions like battery optimization.

Step-by-step Instructions

Step 1: Check your internet connection

1. Test another app (e.g., browser, YouTube) to confirm internet access.
2. Switch between Wi-Fi and mobile data.
3. Restart your router if using Wi-Fi.

Step 2: Restart Signal and your device

• Force close Signal and reopen it.
• Restart your phone or computer.

Step 3: Disable battery optimization / background restrictions

• Android:
  1. Settings > Apps > Signal > Battery > Battery Optimization.
  2. Select Don’t optimize.
• iPhone:
  • Ensure Low Power Mode is off (Settings > Battery).

Step 4: Check Signal permissions

• Android:
  • Settings > Apps > Signal > Permissions → Allow Network/Internet and Background data.
• iPhone:
  • Settings > Signal → Enable Mobile Data.

Step 5: Update Signal

• Go to Play Store or App Store.
• Update to the latest version for bug fixes and improved connectivity.

Step 6: For Signal Desktop

1. Ensure your phone is online — Signal Desktop requires your phone to be connected.
2. If sync fails, unlink and re-link your device:
   • Signal Desktop > File > Preferences > Linked Devices.
   • Tap Link New Device in Signal mobile app.

Best Practices / Tips

• Keep Signal updated to the latest version.
• Use Wi-Fi for calls when possible — mobile data may cause delays in poor coverage.
• Restart your phone every few days to refresh background processes.
• Avoid third-party apps that interfere with internet access (e.g., aggressive firewalls, task killers).
