Get info on Public Wi-Fi Protection available with AT&T Mobile Security Plus.


Use Public Wi-Fi Protection to guard your data

This VPN security feature automatically checks each Wi-Fi® network connection before you link your device to make sure the network is secure. Public Wi-Fi Protection:1
  • Safeguards your data if you join an open (unsecured) domestic Wi-Fi network at restaurants, hotels, airports, and other similar places. 
  • Doesn't activate when you connect to a Wi-Fi network that it deems secure, like your home Wi-Fi network. 
Heads up: Public Wi-Fi Protection is only available in the U.S. , not while traveling abroad. It isn't compatible with certain video streaming apps due to geographic restrictions, so that data bypasses or disconnects your VPN connection.

Your security is our top priority. Learn more about AT&T ActiveArmor
