How to Replace Your Carrier on Android Using These Fully Open-Source Tools
(www.makeuseof.com)
Do you guys know a single person who uses Wi-Fi only? Because I don't lol. You don't want your carrier to collect data? Use VPN all the time and don't use regular SMS and calls, but e2e alternatives like Signal offers.
Its all about your threat model and the security/privacy level you want to achieve. If you don't want cell tower triangulation to give away your location, this is a great free option. But VPN's only alter the IP address given to websites, even with a WiFi only setup if you don't disable WiFi scanning, that'll give your location away too.
Edit: grammatical misfire
