Advantages and Disadvantages of Wifi Calling


Over the years, communication has experienced remarkable transformations. In the past, calling re­lied on landline tele­phones connected via a wire­d network. However, with the­ emergence­ of mobile phones, communication became more portable and convenient. The introduction of mobile networks re­volutionized calling and allowed people to make calls on the go without being confined to a fixe­d location.


WiFi calling has now gained popularity as a te­lecommunications solution. It highlights significant improvements in calling capabilities. Wi-Fi calls have allowed users to make and receive phone calls through a Wi-Fi network rather than sole­ly relying on cellular networks.


However, just like any other technology, it’s important to consider the advantages and disadvantages of Wi-Fi calling before fully embracing this communication method. WiFi calls come with their own pros and cons, and understanding them helps you decide if WiFi calling is right for you.

What is WiFi Calling?

WiFi calling, aka VoWifi calling, refers to making or receiving calls over a WiFi network rather than the traditional cellular network. Your phone uses WiFi to create a mini cell tower and routes calls and messages. You can make calls without issues, even in areas with weak cellular signals. The Wi-Fi call technology enables you to communicate from every corner of the world simply by connecting to the internet. 


You can use your home internet or WiFi hotspot to make WiFi calls even if there isn’t a weak mobile network. It works like a regular phone conversation - you dial a number and talk as usual. The only difference is that you are talking over the Internet, which gives you more mobility and allows calls even when you lose cellular service coverage.

Does it Cost for Wi-Fi Calling?

A WiFi connection is specifically mandatory for WiFi calling. It is extremely beneficial to you when you have very weak cellular signals or when it is not available. It provides a much stronger and more reliable connection to make phone calls. It can be an excellent option for people who are continuously busy with phone calls, as it helps to save phone call costs. 


While talking about phone charges, Wifi calling cost doesn’t include any additional money for phone calls. Its cost is taken from your monthly voice plan. However, you may have to pay a fairly minimum amount while making an international call.

What are the Pros and Cons of WiFi Calling?

Tele­communications providers now offer Wifi calling, and a wide range of Android and iOS smartphones support this feature. It serves as a conve­nient solution when you are experiencing weak cellular rece­ption in certain areas but have access to a stable­ Wi-Fi network. Wi-Fi calling has numerous advantages that enhance the overall calling experience. However, there are a few disadvantages of wifi calling as well.

Advantages of Wifi Calling

Wifi calling provides various benefits such as reliability, mobility, and high-quality phone calls. Below are discussed some of its significant advantages.

Backup Cellular Coverage

While cellular networks are not available everywhere, wifi calling acts as a backup when you don’t have access to the cellular signal or have weak cellular signals. It helps you make phone calls via internet. Nowadays, you can get a wifi connection or use your personal wifi hotspot in most parts of the world, meaning you can call from anywhere you want without cellular coverage.

No Need for Additional Apps

WiFi calling is an in-built feature of most advanced smartphones. So, you don’t need any type of additional application to utilize this feature. All you need to do is enable this feature on your smartphone, and you are ready to make wifi-based calls. No type of application or hardware is required for it to function.

Offers More Reliable Connection From Home

An internet connection is far more reliable than regular cellular coverage. In the modern world, there is internet connectivity in every household. But still today, there is only one cellular tower in most of the rural areas, which doesn’t provide reliable connections to make phone calls from your home. People struggle to get a decent cellular signal to make phone calls. Moreover, physical things like buildings can interrupt the cellular signal. In that case, WiFi calling offers a more reliable connection from your own home.

Disadvantages of Wifi Calling

Calling over wifi offers the best phone communication solution. Still, there are some disadvantages of wifi calling that you must consider when enabling wifi calling as your primary phone call feature.

Unreliable Signal Strength in Public Places

Although wifi calling is the best option for your home, public places with many people sharing the same internet connection may interrupt Wi-Fi calls. Places like restaurants, hotels, airports, etc., have a common internet connection, which slows the speed of the internet. Additionally, the public internet connection may not be as secure as your home wifi connection. So, a Wi-Fi connection may not be the best option in public places, as it can provide unreliable signal strength.

Wi-Fi Hotspots Aren't Always Available

You will need a wifi connection for Wi-Fi calling, but wifi connections may not be available in every possible place. You may not find a Wi-Fi hotspot in most places, even though the number of public wifi hotspots has increased by 73% over the years from 2018 to 2023. Using a personal wifi hotspot may temporarily solve this problem, but it may also not give you a reliable connection for Wi-Fi calls. You may switch to the cellular phone system if you cannot find a stable WiFi hotspot.

Wifi Calling Drains Your Battery Faster

Utilizing Wi-Fi calling can be a lifesaver when cellular signals are weak or unavailable. However, it comes with a trade-off: increased battery consumption. When you make or receive calls over Wi-Fi, your smartphone expends more energy maintaining a stable connection and ensuring call quality. The constant search for a robust Wi-Fi signal and the data transfer during a call places a greater strain on the battery than traditional cellular calls.

Wi-Fi Calling From Carriers is Still a Relatively New Technology.

WiFi calling is a relatively new technology compared to cellular calling. Most people still don’t know this feature exists in their smartphones, as wifi call feature is still unavailable in some countries.
