What Is WiFi Calling & How Does It Work ? (+Detailed Guide)

When you experience cellular service issues, you 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, WiFi 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 WiFi calling, and how does WiFi calling?

Let us explore all the aspects of WiFi calling in detail.

What Does WiFi Calling Mean?

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

WiFi 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. WiFi 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.

WiFi Calling means receiving incoming voice or video calls or making outgoing calls with an internet connection instead of a mobile network. Some network providers offer internet connection service, which allows you to make free WiFi calls to anyone, from anywhere, at any time.

WiFi calls do not require a high-quality internet connection, nor do they require a large bandwidth. It takes 1MB for a voice call and between 4 and 6MB for a video call.

Why Do Individuals Prefer WiFi Calling?

The most important aspect is that if you have access to the internet, you can make free WiFi calls. However, you must pay for internet connections, such as mobile data and internet service providers. WiFi calling saves users a significant amount of money compared to calling services requiring a sim card. Using WiFi calling, international calls can be made for free. You may be familiar with how expensive international calls are.

Internet calling uses your phone’s WiFi networks to boost voice calls instead of LTE or 4G data. To make a call, the similar cellular data used by WiFi VoIP must be transmitted over the internet via the user’s WiFi connection.

As a result, we achieve a far better and more sustainable connection, greatly enhancing the connection’s quality.

How Does It Work Effectively?

The term “WiFi calling” means a feature that enables individuals to make and receive texts and phone calls using a WiFi network rather than the network provided by their telecom carrier. Your phone transmits voice data packets through WiFi and the internet to the individual on the other side of the call.

Using a Voice over Internet Protocol, or VoIP, to place a call over WiFi is the most simple and effective method. It establishes a phone line by communicating with a carrier via the internet.

Virtual private network (VoIP) technology is the core of major messaging apps such as WhatsApp, Skype, and Facebook Messenger. Because of the features of today’s devices, making a reliable network connection doesn’t require much effort from you. However, WiFi calling functionality is required, common on most smartphones manufactured after 2017.

Requirements:

• A mobile phone with WiFi Calling functionality.
• A carrier that lets you make calls over WiFi (many do).
• WiFi speeds of at least 2 Mbps during voice calls and 10 Mbps during video calls are required. Preferred: 15 Mbps with an 801.11n (WiFi 4) or higher WiFi Router.

How To Make A WiFi Call?

There are numerous iPhone and Android applications available for making WiFi calls. WhatsApp is the ideal example of a WiFi calling app because it enables you to make freely available voice and video calls anywhere in the world without encountering any difficulties. Having your WiFi network or modems at home is preferable if you want to make calls over WiFi and use mobile data while away from home.

WiFi calling is based on Voice over Internet Protocol, the underlying technology that allows for a superior calling experience. You can choose your business’s most appropriate billing plan and phone number. It’s also a great way to avoid high international rates from your cell phone company. With the technological advancements of wireless routers, you can make secure network connections without call drops.

Does It Consume More Power And Data Than Normal?

WiFi Calling is significantly more energy-efficient in the big scheme of things. On an individual basis, a call for 5 minutes will cost you roughly 4-5MBs. In addition, power usage is typically lower than a standard phone call, especially in regions with poor cell phone service.

Moreover, mobile data depends on cell towers, which can be costly to install and maintain. WiFi calling uses telecom internet cables, saving energy.

What Is The Cost Of WiFi Calling?

Traditionally, cellular phone calls are deducted from a user’s monthly allowance. The WiFi calling functionality is comparable. WiFi calls use your existing monthly voice plan at no extra cost.

You do not need to pay anything to use WiFi calling. Users incur no additional costs in using this service, as it is provided at no cost. However, they need to check with their service provider to ensure the feature is active on their end and that their device is suitable.

It’s an excellent option for remote employees. When you make calls across borders, you won’t be subject to the exorbitantly high prices typical of international calls. You are simply making international long-distance calls using the data allotted to you from your plan.

How Do I Make WiFi Calls With My Android?

If you have an Android phone, you need to get apps that work with it. Despite this, some apps can be installed on your phone regardless of its operating system. Some of them are Facebook, Whatsapp, and Skype. Therefore, it is very simple to use; all you need to do is open the appropriate application. A call or video call can be initiated later by selecting the appropriate button. In addition, companies like Google have created specialised software, such as Google Talk.

However, these apps use VoIP, which is distinct from the WiFi calling android technology. Therefore, you must configure your smartphone’s WiFi calling feature before you may use it without connecting to a service or launching an application. You might want to know that there are many different applications from which to choose the one that best meets your requirements.

What Benefits Does WiFi Calling Offer?

• WiFi calling has numerous advantages.

What Is The Difference Between WiFi Calling And Cellular Data?

WiFi calling enables communication with remote locations. You are not required to be nearby a cell tower. The only requirement is an Internet connection.

However, WiFi connections can be weaker than cellular data connections. Therefore, if a large number of individuals are accessing the WiFi connection at the same time, voice quality may be affected. This frequently occurs in busy areas, such as shopping centres or stadiums.

WiFi calling can experience network interruptions and other VoIP issues. You can avoid these problems, but if your network connection isn’t good, you might hear echoes or have a delay.

Wi-Fi-based video calls may deteriorate as a result. This means it may not be the greatest choice for remote workers at airports with crowded WiFi networks. They would likely have a greater cell phone connection. Consequently, cellular coverage is consistent in urban areas.

Moreover, WiFi calls might extend your battery performance. A battery can be drained by a device that persistently looks for a cellular connection to connect to. A device that makes calls over WiFi doesn’t. Instead, it only connects to a single network and remains connected to that network until you manually disconnect it.

Final Thought

WiFi calling enables businesses to adopt a hybrid work environment. Teams are increasingly operating from various areas. Thus, virtual workers need communications tools. WiFi calling is one tool that facilitates simple and flawless remote communication. It is an all-in-one, low-cost, and secure future communication method.

While most people are content to use a smartphone or desktop software for WiFi calling, more large businesses may choose to invest in VoIP phones and conferencing calling.
