  • Post author:

When you experience cellular service issues, try to hold your smartphone to the ceiling, avoid certain workplace areas, and stick your arm outside the window to receive more network bars. However, Wi-Fi Calling can fast and effectively resolve this issue. In addition, due to technological advancements, today’s internet users no longer need SIM cards to make and receive phone calls. So, what is Wi-Fi calling, and how does Wi-Fi calling?

Let us explore all the aspects of Wi-Fi calling in detail.

What is Wi-Fi Calling ?

It has been observed that the performance of mobile networks has declined during the past few years. As a result, call drop has become the new normal, and the inconsistent voice quality has ruined the user experience further. Wi-Fi calling can fix these issues.

Wi-Fi Calling lets your phone use your ISP’s landline high-speed internet network—your home’s WiFi—instead of your carrier’s 4G LTE & 3G service for phone calls.

The internet is used in place of a traditional phone line or network during a WiFi call. Wi-Fi calling allows you to avoid using your mobile provider’s data network. Instead, you will use the WiFi network to make voice calls. You can access a WiFi connection in a hotel, at home, in the office, or at a paid or free WiFi hotspot. Therefore, WiFi connectivity is required to access this service.

  7. Reliability: Wi-Fi networks are often more stable and consistent than cellular networks, making Wi-Fi Calling a dependable option for important calls and business communication.
  8. Compatibility: Wi-Fi Calling is supported on a wide range of devices and operating systems, including smartphones, tablets, and even some laptops.
  9. Privacy and Security: Wi-Fi networks are typically encrypted and secure, which can provide users with a higher level of privacy and security during calls and text messages.

Overall, Wi-Fi Calling offers convenience, cost savings, and improved communication capabilities, making it a preferred choice for many individuals, particularly in scenarios where cellular coverage is limited or costly.

How Does Wi-Fi Calling Work ?

Wi-Fi Calling works by allowing your smartphone to make voice calls and send text messages over a Wi-Fi network instead of relying solely on a cellular network. Here’s how it works:

  1. Connection to Wi-Fi: When your phone is connected to a Wi-Fi network, it can use that network to transmit voice and data.
  2. Initiating a Call: When you make a call or send a text message, your phone’s operating system and carrier software determine whether there’s a Wi-Fi network available.
  3. Switching to Wi-Fi: If a Wi-Fi network is available and Wi-Fi Calling is enabled on your device, your phone will automatically switch to using Wi-Fi for the call or message.
  4. Call Routing: The call or message is transmitted as data packets over the Wi-Fi network to your carrier’s servers.
  5. Carrier Integration: Your carrier processes the call or message over the Wi-Fi network as if it were on the cellular network.
  6. Seamless Transition: If you move out of Wi-Fi range during the call, your phone will seamlessly switch back to the cellular network without dropping the call.

Wi-Fi Calling is especially useful in areas with poor cellular coverage or when traveling internationally, as it can help you avoid high roaming charges. It also contributes to improved call quality, especially in places with a strong Wi-Fi signal.
