If you don’t want to rely on your carrier’s mobile network to make calls and send and receive text messages, WiFi calling is the solution of choice.
You can use the Free Calls app to make unlimited calls and send free texts, but you still need a phone service provider as an intermediary.
WiFi calls can help you achieve high quality calls, especially if you are working remotely and need to communicate with your team. If you have strong WiFi network coverage, you can also use HD (High Definition) Voice in your cloud phone system to enjoy clearer and clearer call quality when chatting with family and friends.
On iOS devices, this feature is a bit hidden, but it analyzes all the information you need to know about WiFi calls on your iPhone.
What is a WiFi call on iPhone?
WiFi calling is a hidden feature of iPhone that allows you to make and receive video and voice calls over a WiFi connection instead of using a cellular connection.
Free services rely on a technology called SIP / IMS (IP multimedia subset) This is useful if your carrier’s phone signal is unstable, but you can access WiFi. WiFi calls also work when you’re connected to a public hotspot at the airport or your favorite coffee shop.
Most major carriers offer WiFi calling services at no additional charge when making calls to US numbers. If you make an international call via WiFi call, you may be charged an international call charge. A voice prompt interrupts the call and informs you that international charges may apply. You can choose to complete the call or hang up to avoid long-distance charges.
How WiFi Calling Works on iPhone
Before using WiFi calling, you need to make sure your device is compatible and HD Voice compatible (iPhone 6 or later). In addition, you need to provide an address so that emergency services can contact you if you call 911.
WiFi calling technology routes voice packets through the carrier’s closest cell tower and tunnels them over the Internet to establish a connection. The packet is bounced to the person talking over the network.
In short, you’re communicating with someone else, but you’re not using the cell tower to do that in the traditional sense.
All apps such as Skype, WhatsApp and Facebook Messenger make calls using Voice over Internet Protocol (VoIP) technology. Basically, WiFi calling uses VoIP to provide a better calling experience and eliminate the high charges that mobile operators charge to international calls without disconnecting.
Unlike cellular connections, which require a cellular network to connect and thereby drain the device’s battery, you can’t use WiFi calling. In fact, WiFi calls using the iPhone can extend battery life by connecting to a single network and staying there until you disconnect.
The main drawback of WiFi calls is that they are affected by network interruptions and can affect all calls made using WiFi.
