Remote Play Away From Home over Mobile Data

• Sign in once, then connect over 5G, 4G or another Wi-Fi, usually with no router setup
• Automatic UPnP port mapping, and home VPNs such as Tailscale work too
• Tells you when your carrier's shared address (CGNAT) blocks the connection

• It works at home but not when I am out.
• Remote says it needs a console match first.
• It says Remote play is off on the console.
• I tapped Start streaming and the card switched to Remote.
• I picked Remote at home, but it streams locally.
