What is Wi-Fi calling on an iPhone?

When cellular service is inadequate, Wi-Fi calling allows your smartphone to automatically switch to Wi-Fi to make or receive calls. Most phones come with a simple option for Wi-Fi calling, which uses your regular number. Poor cellular signals force your phone to use more power to strengthen the connection. Wi-Fi calling can improve call quality while extending the battery life of your smartphone.

In this article, we will discuss what exactly Wi-Fi calling is and how to use it.

What is Wi-Fi calling?

Wi-Fi calling works similarly to other voice over IP (VoIP) programs, such as Viber and WhatsApp. However, it is distinguished by some crucial features.

• For Wi-Fi calling, you don’t need any specific app to make and receive calls or send and receive messages, like FaceTime, WhatsApp, Viper, Skype, etc. You can simply use the messaging app or the built-in dial pad. on your phone to make Wi-Fi calls, just like regular calls.
• No additional apps are required for the person you are trying to call or message. The person or number you are calling will receive the call on their phone just as you would if you made a normal call. This is because Wi-Fi calls and texts are ultimately sent over a mobile network (after traversing your wireless connection). They also don’t need to have specific apps on their phones.
• Text messages and phone calls appear to come from your number. Your calls and text messages will appear to other people who receive them as coming from your phone. This is especially useful for 2FA and account registration services that do not accept VoIP numbers.
• You can dial standard phone numbers, including landlines and toll-free calls. Wi-Fi calling allows you to communicate with more people than just other mobile phone users. Similar to using a cellular connection, you can call landlines, customer service numbers, and emergency services.

How does it work

Like Wi-Fi VoIP, Wi-Fi calling works by sending mobile data packets over a Wi-Fi and Internet connection. Data is transferred from the Internet to the cellular network and then back to the caller. The smartphone must support Wi-Fi calling for it to work. The service is an updated version of the Generic Access Network (GAN) protocol.

First, users need to confirm that both their carrier and phone support Wi-Fi calling. Each carrier may have different specifications. When Wi-Fi calling is enabled, your device uses it whenever it is connected to Wi-Fi. The voice over LTE (VoLTE) or a mobile receiver symbol with a Wi-Fi symbol may appear in the phone’s notification bar along with the usual call and chat log entries for calls and messages.

A user can also put their phone in airplane mode to ensure that they opt for Wi-Fi calling. You may miss a call if you go out of range of a Wi-Fi router, depending on the provider, connection, and phone.
