Wi-Fi calling is as you would expect - Making a phone call using a Wi-Fi network instead of the traditional method of using your mobile provider’s cellular network. This method of calling is becoming extremely popular and there are plenty of companies that use this technology such as Microsoft’s Skype and even messaging apps like Facebook Messenger and Whatsapp.
There are many advantages to using Wi-Fi calling over the traditional cellular network, but the main ones are to get around the often poor cellular network coverage and as a cost reducing exercise.
There are many places in the world where you simply don’t get great network coverage - No matter how many cell phone masts and transmitters a company installs, the cellphone network will not provide 100% coverage - This is where Wi-Fi calling comes into play and allows you to still make calls in the absence of a cellular network. Furthermore, using a Wi-Fi network to make calls means you do not have to pay the associated cost per minute that you would from making a cellular call through your mobile network.
Using a public Wi-Fi network always has associated security risks - The fact that it’s a public network is by far the biggest - You simply do not know who else is accessing the network or what they are trying to do. There are many people out there who want to cause disruption or try and steal your personal information for fraudulent purposes and what better way to do it than to intercept a phone call made on a public Wi-FI network with low security? There have been numerous instances in the past where individuals have managed to prove vulnerabilities within the Wi-Fi calling system.
A VPN service can be a fantastic way to protect your device and data from attacks and unwarranted attention when making Wi-Fi calls. When making a Wi-Fi call you are trusting that the Wi-Fi network you are connected to is secure and that there is the relevant safety measure in place to ensure your call does not get traced or tampered with in any way.
Using a VPN service takes away that uncertainty and removes the potential threats that could arise from using a Wi-Fi network to make a call. Instead of connecting directly to the Wi-Fi network, you will connect to a VPN (Virtual Private Network) server that will encrypt your data and provide you with a different IP address BEFORE sending your data through the Wi-Fi network. This will ensure that your Wi-Fi call cannot be traced and that you will have a secure connection. Use a VPN service and you can also benefit from its other functionality such as anonymous web browsing and secure online streaming.
