Free Wi-Fi calling is a new feature of iOS 8, initially introduced by T-Mobile in the US and EE in the UK. Other carriers worldwide will also adopt Wi-Fi calling for making and receiving calls over Wi-Fi networks instead of relying solely on mobile networks in the near future.

Free Wi-Fi calling utilizes technology known as Unlicensed Mobile Access (UMA) or Generic Access Network (GAN), eliminating the need for mobile network support. This technology enables your iPhone to make and receive calls over standard Wi-Fi networks.

Requirements for this include: T-Mobile only supports Wi-Fi calling for iPhone 5C, iPhone 5S, iPhone 6, and iPhone 6 Plus. Follow these steps to activate Wi-Fi calling:

Step 1: Go to Settings

Step 2: Navigate to Phone

The Wi-Fi calling feature proves highly beneficial for users; however, it still faces various limitations, such as reliance on service providers and support for high-end iPhone models. Vietnamese users must await future updates to access this special feature.
