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.
