Check Your Internet Connection
A weak or unstable internet connection is the most common reason Snapchat calls fail. Try these steps:
- Switch between Wi-Fi and mobile data to see which works better
- Test your connection speed using apps like Speedtest to check for latency or packet loss
- Reset your router or modem if using Wi-Fi
- Toggle Airplane Mode on and off to refresh your mobile network
- Move closer to your router or to a window for better signal strength

Outdated apps often have bugs that affect calling features. Make sure both Snapchat and your phone's operating system are current.

Check Microphone and Camera Permissions
If others can't hear you during calls, it's likely due to microphone permissions or settings.
- On iPhone: Go to Settings > Privacy & Security > Microphone and ensure Snapchat is allowed
- On Android: Go to Settings > Apps > Snapchat > Permissions and grant microphone and camera access
- Check that your phone isn't on silent mode or low volume
- If using Bluetooth headphones, ensure they're properly connected or try using your phone's internal microphone

Clear Cache and Free Up Storage
Corrupted cache files or low storage space can cause Snapchat features to malfunction.
- On Android: Go to Settings > Apps > Snapchat > Storage > Clear Cache
- On both iPhone and Android: Inside Snapchat, go to your profile > gear icon > Clear Cache (this won't delete your chats or memories)
- Delete old files and apps you don't need to free up storage space

Check Blocked Contacts and App Settings
Sometimes the issue is with your Snapchat settings rather than technical problems.
- Open Snapchat, go to your profile, and tap the gear icon for Settings
- Scroll to Blocked and make sure the person you're calling isn't listed
- Verify that camera and microphone permissions are enabled for calls within Snapchat
- Some users report issues when switching between voice and video call modes without proper permissions

Enable Cellular Data for Snapchat
If you're using mobile data instead of Wi-Fi, confirm that Snapchat can access it.
- Go to Settings > Cellular/Mobile Data > Snapchat and toggle on data access
- Check for any data saver or background restrictions that might be blocking Snapchat

Restart the App and Your Phone
Simple restarts can resolve many temporary glitches.
- Completely close Snapchat (swipe away or kill the process), then reopen it
- Log out and back into Snapchat to reset session tokens
- Restart your phone completely - power off, wait 30 seconds, then turn back on
Check for Server Issues
Sometimes the problem isn't on your end. Snapchat might be experiencing server outages or maintenance.
- Check Snapchat's official system status page for known issues
- Look on social media platforms to see if others are reporting similar problems
Additional Troubleshooting Steps
If the basic fixes don't work, try these advanced solutions:
- Disable background noise suppression in your phone's accessibility settings
- Check for microphone mode glitches in your phone's privacy settings
- Ensure your phone's physical mute switch isn't silencing calls (iPhone)
- Clean your microphone if it's blocked by dirt or debris
- Test your microphone in other apps like voice memos to rule out hardware issues
When All Else Fails
If nothing else works, uninstall and reinstall Snapchat from the App Store or Google Play. This gives you a clean install without corrupted files, though you'll need to log back in afterward.
Most Snapchat call issues can be resolved with these troubleshooting steps. Start with the simplest solutions like checking your internet connection and updating the app, then work through the more advanced fixes if needed.
