Is WiFi Calling Safe?
First, the good news: Yes, WiFi calling is safe, even though your data (your voice) is being sent over maybe unsafe WiFi networks. That’s due to the fact your mobile carrier encrypts your voice, including when it’s sent over WiFi networks. Therefore, even if your voice is sent over public Wi-Fi hotspots, it’s being encrypted by your cell phone provider, making it useless to Wi-Fi hackers.
However, a few voice over-Wi-Fi apps bypass your mobile carrier and therefore might perform no encryption. If you are using one of these apps and your phone is connected to a public Wi-Fi hotspot, you can be in danger of being listened to by Wi-Fi hackers.
So, if you are using a voice-over-Wi-Fi app on your phone, be safe by using a VPN. VPNs encrypt all the data coming out and, on your phone, including your voice.
Wi-Fi Calling is the next great thing for your mobile phone, so be sure you are making the correct call by safeguarding your private phone calls with a VPN.
What are the advantages of making calls over Wi-Fi?
One of the largest appeals of Wi-Fi calling is that it offers an alternative to cellular technology and can save you money. For folks who struggle with choppy cellular coverage, either because they reside in a rural area or because they just ended up with a bad combination of geographic area and carrier, it’s amazing news. Wi-Fi calls frequently don’t count against your designated number of cellular minutes, so you can talk as long as you like over a Wi-Fi connection without fretting about extra charges.
What are the disadvantages of Wi-Fi calling?
Mobile carriers are still working out the kinks. If you’re on a call while in transit and your Wi-Fi signal drops, the call could be dropped as well while your phone attempts to connect to a cellular network. But the largest disadvantage is the possible security risk.
