Does the POCO X4 Pro 5G support the Wi-Fi calling?

The POCO X4 Pro 5G doesn’t support the Wi-Fi calling.
Wi-Fi calling is a feature that allows you to make and receive phone calls over a Wi-Fi network instead of using your cellular network. This can be especially useful in areas with poor cellular reception but strong Wi-Fi signals.
However, not all phones support Wi-Fi calling. Most major carriers support Wi-Fi calling, but availability will vary by region and carrier. Please check your phone's specifications or contact your carrier for compatibility.
