iPhone users often assume that Apple built-in security makes a VPN unnecessary. While iOS is indeed more secure than many platforms, it does not encrypt your internet traffic or hide your IP address from websites, ISPs, or network operators. An iPhone VPN adds a critical layer of privacy protection that iOS alone cannot provide.
We tested 12 VPN apps on iPhone 15 Pro and iPad Air, evaluating connection stability, battery impact, speed performance, ease of use, and iOS-specific features like Siri Shortcuts integration and Always-On VPN support.
Top VPNs for iPhone
1. NordVPN -- The best iOS VPN app with NordLynx protocol delivering excellent speeds, minimal battery drain (less than 3% additional daily usage), Threat Protection Lite blocking ads and trackers, and Siri Shortcuts support for voice-activated connection.
2. ExpressVPN -- The most polished iOS interface with one-tap connection, Lightway protocol optimized for mobile, split tunneling for routing specific apps through the VPN, and industry-leading connection reliability.
3. Surfshark -- Unlimited device connections protect your iPhone, iPad, Mac, and Apple Watch simultaneously. CleanWeb blocks ads system-wide, and the widget support provides quick connection from the home screen.
iOS-Specific Features to Look For
IKEv2 and WireGuard support: These protocols handle network switching (cellular to Wi-Fi) seamlessly, maintaining your VPN connection as you move between networks.
Kill switch: Ensure the VPN app supports the iOS network extension API for a proper kill switch that blocks traffic if the VPN drops.
Always-On VPN: Some VPN apps support iOS Always-On VPN configuration, ensuring your connection is always protected without manual activation.
