The answer is not a simple yes or no. In this article, we will delve into the technology behind Wi-Fi calling, its limitations, and what you need to know in case of an emergency.
What is Wi-Fi Calling?
Wi-Fi calling, also known as Voice over Wi-Fi (VoWi-Fi), is a technology that allows you to make voice calls using a Wi-Fi network instead of a traditional cellular network. This feature is available on many smartphones, including iPhones and Android devices. Wi-Fi calling uses the internet to connect your call, allowing you to communicate with others even when you don’t have a strong cellular signal.
How Does Wi-Fi Calling Work?
Wi-Fi calling works by using the internet to connect your call to the recipient’s phone. Here’s a step-by-step explanation of the process:
- Your phone detects a nearby Wi-Fi network and connects to it.
- When you make a call, your phone sends a request to the Wi-Fi network to connect the call.
- The Wi-Fi network forwards your request to a nearby cell tower or a specialized server.
- The cell tower or server connects your call to the recipient’s phone using traditional cellular networks.
- The call is then routed through the internet, allowing you to communicate with the recipient.
