What is WiFi calling and how does it work?
WiFi calling, also known as Voice over WiFi (VoWiFi), is a technology that allows users to make and receive phone calls using a WiFi network instead of traditional cellular networks. When you enable WiFi calling on your phone, it uses the internet connection to make voice calls, just like how you would use video conferencing apps like Zoom or Skype. This technology is especially useful in areas with poor cellular reception, such as rural areas or buildings with thick walls.
WiFi calling is not a separate app or service, but rather a feature built into your phone’s operating system. When you’re connected to a WiFi network, your phone can automatically switch to WiFi calling mode, allowing you to make and receive calls as you would normally. The call quality is usually crystal clear, and you can even use other apps or browse the internet while on a call, just like you would on a regular phone call.
Is WiFi calling available on all phones?
Not all phones support WiFi calling, but most modern smartphones do. To check if your phone supports WiFi calling, go to your phone’s settings and look for the option to enable WiFi calling or VoWiFi. If you don’t see it, you can check your phone’s documentation or contact your phone’s manufacturer to see if it’s available on your device. Most iPhone models from iPhone 6 and later, and many Android phones from popular manufacturers like Samsung and Google, support WiFi calling.
Keep in mind that even if your phone supports WiFi calling, it may not work on all networks or in all countries. It’s best to check with your carrier to see if they support WiFi calling and if there are any specific requirements or restrictions.
Is WiFi calling secure?
WiFi calling uses the same security protocols as regular internet communications, which means it’s generally secure. However, as with any online activity, there are some security risks to consider. For example, if you’re using a public WiFi network, your calls could be intercepted by hackers. To minimize this risk, make sure to use a secure and trusted WiFi network, and avoid using public WiFi networks for sensitive activities.
