iOS has native VPN support built into Settings, but most users choose a VPN app rather than manual configuration. Here is what to look for in a VPN for iPhone and iPad and which services perform best on iOS.
VPN Protocols on iOS
iOS supports IKEv2, IPSec, L2TP, and OpenVPN (via third-party apps). The best protocol for most iOS users is IKEv2: it is fast, built into iOS natively, and handles network switching well (important when moving between WiFi and cellular). WireGuard is also available on iOS via the official WireGuard app -- several VPN providers support it. OpenVPN requires a third-party client (the OpenVPN Connect app).
Best VPN Apps for iOS 2026
ExpressVPN's iOS app is consistently rated the best-designed VPN app on iOS. It uses its own Lightway protocol (similar to WireGuard in speed) and the app integrates cleanly with iOS shortcuts and widgets. NordVPN's iOS app uses NordLynx (WireGuard-based) by default and has a clear server map interface. Mullvad VPN has a minimal, privacy-focused iOS app with no account required -- you pay anonymously with a token. For families: Surfshark's iOS app supports unlimited simultaneous connections on one subscription.
Using VPN with iCloud Private Relay
Apple's iCloud Private Relay (available on iCloud+ plans) is not a full VPN -- it only masks your IP for Safari traffic, not all traffic. Running a VPN and Private Relay simultaneously can cause conflicts. Most VPN providers recommend disabling iCloud Private Relay when using their app, or the VPN may block the Relay traffic. Check your VPN provider's iOS-specific guidance.
