Making a Wi-Fi call on a phone is nothing new. In the past, we download Skype on our phones and patched a call using a Wi-Fi connection instead of a cellular one. Of course, there are plenty of apps having a similar function as Skype, such as WhatsApp and Messenger. Phone makers also announced their own Wi-Fi calling apps.
With the need growing, legacy carriers who use traditional cellular technology have adopted Wi-Fi calling as well. And this type of Wi-Fi calling is what we want to discuss here. You may still want to ask what’s the difference and why we need it. Let’s learn more about it.
What is Wi-Fi calling?
If your phone supports Wi-Fi calling, you can make a voice call via a Wi-Fi network, rather than your carrier’s network connection. The Wi-Fi connection is the same you have set up at home or the one you happen to connect when you’re out. It’s like any other phone call, using regular phone numbers. You make and receive calls with Wi-Fi using your phone number. No apps needed. It will help you connect when cellular service isn’t available or you’re having poor signal issues.
