What to Do If Wi-Fi Calling Isn’t Working on vivo X300 Pro

Wi-Fi Calling lets your phone make and receive calls using a Wi-Fi network instead of relying only on cellular coverage. It is extremely useful when you are indoors, in basements, or in areas where the mobile signal is weak.

If Wi-Fi Calling is not working on your vivo X300 Pro, calls may fail, the feature may not activate, or the option may appear disabled. In most cases, the issue comes from a simple setting, network restriction, or carrier configuration that prevents the feature from working properly.

Why Wi-Fi Calling Is Not Working on vivo X300 Pro

• Wi-Fi Calling is disabled in the phone settings.
• Your carrier has not activated Wi-Fi Calling on your account.
• The connected Wi-Fi network is unstable or slow.
• Airplane mode or network settings are interfering with the feature.
• Temporary software glitches affecting the calling service.

1. Make Sure Wi-Fi Calling Is Enabled

Wi-Fi Calling must be turned on manually in the phone settings. If the option is disabled, your phone will always attempt to place calls using the cellular network instead of Wi-Fi.

1. Open Settings, and then tap Network and internet.
2. Tap Mobile network, and then tap Wi-Fi Calling.
3. Toggle the switch on, and then confirm if a prompt appears.

2. Check If Your Carrier Supports Wi-Fi Calling

Not all carriers enable Wi-Fi Calling by default. If the feature is not activated on your account, your phone may show the option but it will not function.

1. Open Settings, and then tap Network and internet.
2. Tap Mobile network, and then check for Wi-Fi Calling availability.

If the option is missing or greyed out, contact your carrier and ask them to enable Wi-Fi Calling for your number.

3. Reconnect to Your Wi-Fi Network

Wi-Fi Calling depends on a stable internet connection. If the network is unstable, the phone may switch back to cellular calling automatically.

1. Open Settings, and then tap Wi-Fi.
2. Tap your connected network, and then tap Disconnect.
3. Select the same network again, and then tap Connect.

4. Turn Airplane Mode On and Off

Refreshing your network connection forces the phone to reconnect to both Wi-Fi and your mobile carrier. This often restores Wi-Fi Calling when it fails to activate.

1. Swipe down from the top of the screen, and then open Quick Settings.
2. Tap Airplane mode, and then wait about ten seconds.
3. Tap Airplane mode again, and then reconnect to Wi-Fi.

5. Restart Your Phone

Temporary software glitches can interfere with calling services. Restarting the device refreshes system processes and reconnects the phone to available networks.

1. Press and hold the Power button, and then tap Restart.
2. Wait for the device to reboot, and then reconnect to Wi-Fi.

6. Reset Network Settings

If Wi-Fi Calling still does not work, your network configuration may be corrupted. Resetting the network settings restores all wireless connections to their default state.

1. Open Settings, and then tap System.
2. Tap Reset options, and then tap Reset Wi-Fi, mobile, and Bluetooth.
3. Confirm the reset, and then reconnect to your Wi-Fi network.

Wi-Fi Calling is designed to make calls reliable even when cellular coverage is weak. Once the correct settings are enabled and your network connection is stable, the feature should work smoothly again on your vivo X300 Pro.
