Wi-Fi Calling is a feature that allows you to make and receive phone calls and send text messages over a Wi-Fi network 

instead of using your cellular network. It’s especially useful in areas where cellular signal is weak or unavailable but you 

have access to a strong Wi-Fi connection. 

Here's how it works: 

• When Wi-Fi Calling is enabled on your phone, it automatically uses Wi-Fi to route calls and texts if your cellular signal is poor. 

• The person you're calling doesn't need to have Wi-Fi Calling enabled — it works just like a regular call from their perspective. 

• Your phone number stays the same, and you can use it just like you normally would. 

Benefits: 

• Better call quality in areas with poor cellular reception. 

• No extra apps needed — it’s built into most modern smartphones. 

• Works internationally (depending on your carrier), often with lower or no roaming charges. 

Requirements: 

• A compatible smartphone. 

• A carrier that supports Wi-Fi Calling. 

• A stable Wi-Fi connection. 

Troubleshooting Steps: 

1. Verify Wi-Fi Calling is Enabled and Working: 

Check settings: 

Navigate to your phone's settings and confirm that Wi-Fi calling is turned on. 

Test Wi-Fi: 

Ensure your phone is connected to a stable and strong Wi-Fi network. Run a speed test on the Wi-Fi network to verify adequate speeds. 

2. Restart Devices and Connections: 

Restart your phone: 

A simple restart can resolve temporary glitches. 

Restart your router: 

Power cycling your modem and router can also help resolve connection issues. 

Toggle Airplane Mode: 

Enabling and disabling Airplane Mode can refresh your phone's network connections. 

Forget and Reconnect to Wi-Fi: 

In your Wi-Fi settings, try forgetting the network and then reconnecting to it. 

3. Update Software and Check Carrier Settings: 

Software updates: Ensure your phone's operating system and carrier settings are up-to-date. 

4. Advanced Troubleshooting: 

Reset Network Settings: If other steps fail, consider resetting your phone's network settings. 

Remove and Reinsert SIM Card: In some cases, removing and reinserting the SIM card can resolve 

connectivity issues.
