In this guide, we’ll explore practical solutions to fix SMS not sending over Wi-Fi and ensure your messages reach their recipients without hassle.
How to Fix Sms Not Sending Over Wifi
Check Your Device’s Compatibility and Settings
Before diving into complex troubleshooting, ensure your device and plan support SMS over Wi-Fi, often known as Wi-Fi Calling. Not all devices or carriers offer this feature, so confirming compatibility is essential.
- Verify Device Compatibility: Check your smartphone specifications or consult the manufacturer’s website to confirm Wi-Fi Calling support.
-
Enable Wi-Fi Calling: Go to your device’s settings:
- On Android: Settings > Connections > Wi-Fi Calling (toggle on)
- On iPhone: Settings > Phone > Wi-Fi Calling > Enable Wi-Fi Calling
- Ensure Your Carrier Supports Wi-Fi Calling: Contact your carrier or visit their support page to verify that Wi-Fi Calling is available on your plan.
Ensure You Are Connected to a Stable Wi-Fi Network
A weak or intermittent Wi-Fi connection can hinder SMS transmission over Wi-Fi. Follow these steps:
- Test Your Internet Connection: Open a browser or app to check internet stability.
- Reconnect to Wi-Fi: Turn off Wi-Fi, wait a few seconds, then reconnect to ensure a fresh connection.
- Switch to a Different Network: If issues persist, try connecting to a different Wi-Fi network to rule out network-specific problems.
- Restart Your Router: Power cycling your router can resolve connectivity issues.
Update Your Device’s Software and Apps
Outdated software can cause compatibility issues with Wi-Fi Calling and SMS services. Keep your device updated:
-
Check for System Updates:
- Android: Settings > System > Software Update
- iPhone: Settings > General > Software Update
- Update Carrier Settings: Sometimes, carrier-specific updates improve Wi-Fi Calling functionality. Follow prompts or check in Settings > About Phone (Android) or Settings > General > About (iPhone).
- Update Messaging Apps: Ensure your default messaging app is up to date via Google Play Store or App Store.
Check Your Messaging Settings
Incorrect messaging configurations can impede SMS delivery over Wi-Fi. Review these settings:
- Enable SMS over Wi-Fi: Confirm that Wi-Fi Calling or SMS over Wi-Fi is turned on in your device’s settings.
- Set Default SMS App: Use a reliable messaging app as the default to avoid conflicts.
- Check for Blocked Contacts or Numbers: Ensure the recipient isn’t blocked in your messaging settings.
- Verify Message Center Number: Sometimes, incorrect center numbers can prevent message delivery. Contact your carrier for the correct number if needed.
Disable and Re-enable Wi-Fi Calling
Turning Wi-Fi Calling off and back on can resolve temporary glitches:
- Go to your device’s settings.
- Find Wi-Fi Calling option.
- Disable it, wait a few seconds, then re-enable.

Reset Network Settings
If problems persist, resetting network settings can clear corrupt configurations:

- On iPhone: Settings > General > Reset > Reset Network Settings
Note: This action removes saved Wi-Fi networks, Bluetooth connections, and VPN settings, so be prepared to reconfigure them.
Contact Your Carrier Support
If none of the above solutions resolve the issue, the problem may originate from your carrier’s network or account settings. Contact customer support and provide details about your device, network, and the problem. They can verify if there are outages, account restrictions, or configurations needed on their end.
