Introduction: What is WiFi Calling?

WiFi Calling enables you to make phone calls over a WiFi network rather than relying on traditional cellular signals. It’s a game-changer for users in low-signal areas or those seeking ways to cut down on communication costs. Whether you’re making calls domestically or internationally, WiFi Calling ensures better voice quality and can help you avoid costly roaming charges.

How Does Wi-Fi Calling Work?

WiFi Calling works by using Voice over Internet Protocol (VoIP) technology, allowing voice calls to be sent and received over an internet connection rather than the traditional mobile network. When you’re connected to Wi-Fi, your device automatically switches from cellular to Wi-Fi Calling, allowing for a seamless communication experience even when you’re in an area with poor cellular coverage.

Who Uses Wi-Fi Calling?

Individuals in Low Signal Areas

Those living or working in places with poor cell signal can benefit immensely from Wi-Fi Calling. By connecting to a Wi-Fi network, users can enjoy uninterrupted calls.

International Travelers

Wi-Fi Calling is an excellent choice for international travelers who want to avoid hefty roaming fees. In certain regions, Wi-Fi Calling can be used without incurring additional charges, depending on the carrier.

Remote Workers

Remote workers who rely on internet communication for work can use Wi-Fi Calling to stay connected with colleagues and clients without worrying about cellular signal issues.

Businesses and Educational Institutions

Businesses and schools with employees or students working remotely or in low-signal areas can take advantage of Wi-Fi Calling to maintain seamless communication.

Is WiFi Calling Free?

In most cases, WiFi Calling is free. However, some carriers may charge you for calls, particularly international calls. It’s always best to check with your provider to understand their specific policies.

WiFi Calling vs VoIP Calling

While WiFi Calling is often confused with VoIP, they differ slightly. WiFi Calling uses your mobile carrier's infrastructure over a Wi-Fi network to make calls. VoIP, on the other hand, is an internet-based system that does not necessarily rely on mobile carrier networks. Below is a brief comparison of the two:
