This is a brief on the basics of VoWiFi, also known as Wi-Fi Calling, its functionality and how to use it.
What is VoWiFi?
VoWiFi is a complementary technology to VoLTE and utilizes IMS technology to provide a packet voice service that is delivered over IP via a Wi-Fi network. Where possible, VoLTE calls may be seamlessly handed over between LTE and Wi-Fi and vice versa.
In simple words, it enables users to use smartphones that support VoWiFi to dial numbers to use voice when a Wi-Fi connection is available.

Users can make outgoing calls even where there is poor cellular connectivity and is designed to address problems of insufficient coverage, especially indoors. So, the VoWiFi enabled SIM is required but it uses the Wi-Fi network to make the calls.
Users incur no extra charge for voice calls made with VoWiFi, but they will need to have an active tariff plan (by the telecom provider) that supports VoWiFi. To use this feature, it must be supported by your carrier/mobile operator in the area where you are using it, as well as the mobile phone.
In order to turn on this feature on realme X2 Pro (and other realme smartphones), please follow the following steps~
Step 1: Connect to a Wi-Fi network
Step 2: Go to the Settings app and select SIM Card & Mobile Data option and Tap on SIM 1 (Make sure you have Airtel/JIO SIM inserted)
Step 3: Then select the option Wi-Fi calling and turn it on. Under the Wi-Fi calling preferences, you should select a Wi-Fi calling preferred option.
Step 4: In some time, you can see VoWiFi calling icon in the status bar
You are all set now! Whenever you will get a call from the other party using the same feature, you can notice the HD icon on the In-call UI besides the call timer. You can find in this screenshot below~
