I have been an enthusiastic customer of Google’s Project Fi cell phone service for more than three years. I also always have a VPN (that I pay for) running all the time in my cell phone. You can read my past articles about the Project Fi cellular service by starting at: https://duckduckgo.com/?q=site%3Aprivacyblog.com+%22project+fi%22&t=h_&ia=web.
I received a pleasant surprise today when I learned that Google is now offering a FREE VPN to all users of the Google Fi cell service and the VPN will be enabled all the time, whether connected by a cellular service connection or a Wi-Fi connection.
All phone calls, text messages, and data will be encrypted for privacy purposes all the time. The always-on VPN will need to be turned on in the Project Fi settings, where the feature is called “Enhanced Network” and labeled a “beta.”
