Use Secure Wi-Fi on your Galaxy phone

The Secure Wi-Fi feature lets you browse the internet safely, even when you’re using unsecured, public Wi-Fi networks. It offers protection by encrypting internet traffic and blocking tracking apps, so you can feel confident when connecting to public addresses. Up to 250 MB of Secure Wi-Fi per month is available automatically, and you can upgrade to another plan at any time.
Note: Secure Wi-Fi may not be supported on all Galaxy phones. Availability may vary depending on the country, carrier, or network environment. Some apps or websites may not allow a Secure Wi-Fi connection.
