Hello! Thank you for reaching out, The Mozilla VPN is compatible with iOS, versions 12.0, and up devices. To use the VPN, all you need to do is sign in and download the client from vpn.mozilla.org. Once you've installed it, you just need to open the client, sign in with your Firefox Account, and hit the switch to turn it on. As soon as it shows you're connected, your traffic will be encrypted and routed through one of our secure servers. I hope you may find this helpful,
