Is Wi-Fi Calling Safe? (Part III)

Public wifi networks are hotspots for hackers trying to steal information from people like yourself.

What are the security concerns related to Wi-Fi calling?

When you send data by Wi-Fi, the security of your info is at the mercy of the network. Public Wi-Fi networks are sanctuaries for phishers and others who lie in wait for the chance to latch on to an unsuspicious user’s connection and steal their personal info. 

If you were to use a Wi-Fi calling app that did not correctly encrypt your data while on an unsafe public network, you would be wide open to information thieves.

Even if you’re using a secure network, you’re putting faith in your cellular carrier. Big-name carriers encrypt voice data so it can’t be accessed by outside parties. Though, one weakness in the flow of information is all that’s needed. 

In 2013, it was discovered that T-Mobile’s WiFi calling feature didn’t properly validate the security certificate on the server-side, creating a chance for a cyberattack. This kind of attack entails hackers making a fake security certificate and tricking the service into believing it is connecting with the proper target.

How can I protect myself?

Fortunately, the inherent risks linked with WiFi calling don’t mean you have to remain clear of this money-saving, convenient technology. Consumers can take steps to protect themselves against unsecured networks and unexpected security failures by using a product such as Hotspot Shield.

Hotspot Shield works by making a Virtual Private Network, or VPN, through which your data passes. You might recognize VPN technology as something used by employers to let remote workers access the secure company network. 

However, it has become a standard solution for savvy users who want to guarantee their data privacy on a daily basis. Also, you won’t have to fight with key fobs and complex software installations like you might have done with a corporate VPN. With Hotspot Shield, making your own VPN is a simple as downloading a file.

Hackers can listen to your conversations.

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.

Is Wi-Fi Calling Safe? (Part I)

Some phone’s can make phone calls through wifi networks. But, how private are your calls?

You may have heard that the new iPhone 6 supports making phone calls over WiFi networks. Using WiFi networks to make calls is the next great thing for mobile phones.

Though, how safe is it to make phone calls with public WiFi hotspots? Are your calls being encrypted? Should you take any necessary steps to safeguard yourself from WiFi hackers?

Welcome to WiFi Calling

Using WiFi networks to make mobile phone calls is referred to as WiFi calling. WiFi calling is the technology that lets packets of data from your cell phone be carried over the Internet and then put back into your cellular network.

This is different from VoIP services such as Skype, which also uses the web to make phone calls due to the fact that with WiFi calling, you can use your cell phone.

Folks are enthusiastic about WiFi calling. If you use the web to make phone calls, those minutes don’t count against your mobile plan. Also, it lets you make phone calls if you are outside your mobile provider’s coverage area.

The technology is not quite perfect yet. There are some problems when a phone goes from a mobile network to a WiFi hotspot. Calls could be dropped. Still, the possibility is there for using WiFi networks in the near future for many cellphones.

Using an App for Wi-Fi Calling

If your phone or carrier doesn’t support Wi-Fi calling, you could always send texts and calls via an app such as Google Voice, Facebook, Line, Skype or one of the numerous other calling apps that could be downloaded onto a cell phone. Remember, you’ll still have to have a data connection such as a carrier plan or Wi-Fi connection.

Wi-Fi calling is usually safe, even though your data is being sent over perhaps an unsecured Wi-Fi network. It is safe since the mobile carrier usually encrypts your voice data.
