What is Wi-Fi Calling?

Quite simply, Wi-Fi calling is a technology that allows you to make and receive phone calls over a wireless internet connection instead of using your 4G or 5G. It’s the solution for staying in touch in areas with poor mobile reception but strong Wi-Fi signals such as an underground station, as it allows you to stay connected by utilising your internet connection to make calls.

How Wi-Fi calling works

Most modern smartphones support Wi-Fi calling, and it’s often a built-in feature that can be enabled in your phone’s settings. Wi-Fi calling relies on Voice over Internet Protocol (VoIP) technology, which converts your voice into data packets. When you make a call, your phone translates your voice into these data packets, transmitting them over the internet through a Wi-Fi network. At the receiver’s end, these packets are reassembled into voice signals, allowing for seamless communication. If your Wi-Fi signal weakens or you move out of Wi-Fi range during the call, the system smoothly switches the communication back to your mobile network without disrupting the conversation, ensuring uninterrupted connectivity.

The pros and cons of Wi-Fi calling

Still contemplating whether to activate the Wi-Fi calling feature? Delve into the pros and cons as we break them down for you below.


Helps with bad mobile signal

Wi-Fi calling proves invaluable in areas with poor cellular reception. By utilising a Wi-Fi network, it ensures you can make and receive calls even when your mobile signal is weak.

Comes as standard on newer mobile phones – no need to install any apps

Modern smartphones often come equipped with built-in Wi-Fi calling features. This means there’s no hassle of downloading or installing additional applications that take up your phone storage —simply activate the feature in your phone settings.

Switches between 4G and cellular

Wi-Fi calling seamlessly switches between Wi-Fi networks, 4G, and networks, ensuring continuous connectivity regardless of the available network types.

Can provide a more reliable connection from home

For those experiencing inconsistent network reception at home, Wi-Fi calling can offer a more dependable and stable connection, enabling clearer calls without interruptions.


Unreliable signal in public settings

Wi-Fi calling might falter in crowded or public areas where the available Wi-Fi networks are congested or weak, potentially leading to call quality issues or dropped connections.

Could still count towards monthly call allowances, depending on your contract

Check your network providers terms—some plans might still count Wi-Fi calls towards your monthly allowances, impacting your overall usage limits.

Requires good bandwidth

For optimal performance, Wi-Fi calling needs a decent bandwidth. In situations where the internet connection is slow or limited, call quality might suffer.

Wi-Fi hotspots aren’t always available

Reliability hinges on the availability of Wi-Fi networks. In certain locations, such as remote areas or during travel, finding a stable Wi-Fi connection might be challenging.

Security concerns on public networks

Using Wi-Fi calling on public networks could pose security risks, as these networks are more susceptible to hacking or data interception compared to private, secure connections.

How to enable Wi-Fi calling

Enabling Wi-Fi calling typically involves going to your phone’s settings, finding the Wi-Fi Calling option under Phone or Network settings, and toggling it on. Ensure your device is connected to Wi-Fi, and remember to verify that your carrier supports Wi-Fi calling for your plan. If you have any issues, contact your network’s support team as they can offer specific guidance.

Which devices support Wi-Fi calling?

Most modern smartphones, including various iPhone models and Android devices from brands like Samsung, Google, and LG typically support Wi-Fi calling. However, compatibility varies by device and network. Check with your network provider or manufacturer for confirmation, as Wi-Fi calling availability might depend on both your device and your subscription plan.
