An iPhone VPN isn’t just a shrunk-down version of the desktop app. iOS restricts what any VPN is allowed to do at the system level — no true app-by-app split tunneling, a kill switch that has to work within Apple’s own on-demand VPN framework, and since iOS 15, a second privacy layer (iCloud Private Relay) that can actively conflict with a third-party VPN if you don’t know to turn one off. The three providers that consistently test well on iPhone specifically — NordVPN, ExpressVPN, and Surfshark — each handle those constraints differently, and the differences matter more on iOS than they do on a laptop.
NordVPN — the best all-around iPhone pick
NordVPN’s iOS app runs on NordLynx, its WireGuard-based protocol, alongside OpenVPN and IKEv2/IPSec as fallbacks, and reviewers consistently clock it among the fastest and most stable iPhone VPN connections in 2026 testing (Security.org’s February 2026 UK/US/Japan server tests put it at the top of the pack). The iOS app includes a kill switch, IP/DNS leak protection, and post-quantum encryption on supported connections, plus Meshnet, which lets you reach a computer or NAS back home securely from your phone — genuinely useful for pulling a file you forgot to pack. Pricing runs around $12.99/mo month-to-month, dropping to roughly $4.99/mo on the 1-year plan and around $3.09-4.99/mo on 2-year billing depending on which reviewer’s live promo you land on, covering up to 10 simultaneous devices. The one iOS-specific gap: no split tunneling on the iPhone app at all (Apple’s platform restrictions are part of why), and some users report the app occasionally failing to connect on first launch, resolved by force-closing and reopening — a minor but recurring annoyance worth knowing about upfront.
ExpressVPN — the smoothest app, built for streaming
ExpressVPN’s Lightway protocol was specifically engineered to be lightweight, and it shows on iPhone: connection times are near-instant and battery drain is noticeably lower than OpenVPN-based competitors. It requires iOS 15+ and reliably unblocks Netflix, Disney+, and Hulu libraries across regions, backed by its MediaStreamer SmartDNS tool for devices that don’t support a full VPN client (useful for an Apple TV paired with your account). The Advanced-tier plan bundles ExpressVPN Keys, a built-in password manager, and ExpressMailGuard, an email-relay/alias service — extras NordVPN and Surfshark don’t match. Pricing starts at around $12.99/mo (Basic) month-to-month, falling to around $4.99/mo on the 1-year plan and around $2.79-3.49/mo on 2-year billing; device limits are tiered by plan (commonly cited as 8, 10, or up to 14 depending on tier and source, so confirm the exact number on the plan page before buying). The tradeoff versus NordVPN: ExpressVPN’s iOS app is polished but pricier at every tier, and its server-location count (214 locations in 113 countries by its own July 2026 count) is smaller than NordVPN’s raw server tally, though that rarely matters for day-to-day streaming and browsing.
Editor’s pick: For most iPhone users we’d start with NordVPN — the fastest and most consistently stable connection in 2026 iOS testing, with genuine extras like Meshnet and post-quantum encryption.

Surfshark — best value if you’re covering the whole family’s devices
Surfshark is the only one of the three with genuinely unlimited simultaneous device connections on every plan, so one subscription covers every iPhone, iPad, and Mac in a household without juggling device slots. Its iOS app supports OpenVPN, WireGuard, and IKEv2/IPSec, adds a home-screen widget for one-tap connect/disconnect (a small but real iOS-specific convenience the other two lack), and includes an ad/tracker blocker plus two-factor login. Because iOS doesn’t allow true per-app split tunneling, Surfshark ships “Bypasser,” a workaround that excludes specific websites (not full apps) from the VPN tunnel — narrower than Android‘s app-level split tunneling, but better than nothing. Pricing is the most aggressive of the three: around $15.45/mo month-to-month on the Starter tier, dropping to roughly $3.19/mo on 1-year billing and around $1.99-2.49/mo on 2-year plans (exact figures vary by promo, so check the live price). The honest tradeoff: Surfshark’s raw speed and streaming-library coverage trail NordVPN and ExpressVPN in most head-to-head tests, even though it’s fast enough for everyday use and 4K playback.
The iCloud Private Relay conflict nobody’s app store listing mentions
If you have iCloud+ and Private Relay turned on, it and a third-party VPN are both trying to route and encrypt your traffic at the same time — Apple’s own support documentation recommends turning off Private Relay for any network where you’re using a separate VPN, since running both together commonly causes connection failures or one silently overriding the other rather than adding a second layer of protection. Check Settings → [Your Name] → iCloud → Private Relay before you troubleshoot a “VPN won’t connect” issue on iPhone; it’s one of the most common self-inflicted causes.
Comparison Table
| VPN | iOS Protocol | Devices | Kill Switch | Price (2-yr, approx.) | Best For |
|---|---|---|---|---|---|
| NordVPN | NordLynx (WireGuard-based) | 10 | Yes | ~$3.09-4.99/mo | Best all-around speed and stability |
| ExpressVPN | Lightway | 8-14 (tiered) | Yes | ~$2.79-3.49/mo | Streaming, polish, extras (Keys, MediaStreamer) |
| Surfshark | WireGuard/OpenVPN/IKEv2 | Unlimited | Yes | ~$1.99-2.49/mo | Families, budget, most devices per account |
Verdict: pick by use case
For most iPhone users, NordVPN is the safest default — the fastest, most consistently stable connection across independent 2026 testing, with a genuine privacy feature set (Meshnet, post-quantum encryption) that goes beyond the basics. If streaming reliability and a smoother day-to-day app experience matter more than price, ExpressVPN’s Lightway protocol and bundled extras justify the higher cost. If you’re covering an entire household’s iPhones and iPads on one plan and want the lowest price per device, Surfshark’s unlimited-connections policy wins on value, even though it isn’t the fastest of the three.
FAQ
Does a VPN slow down my iPhone’s internet speed?
Some slowdown is inherent to any VPN (your traffic takes a longer, encrypted path), but WireGuard-based protocols like NordLynx and Surfshark’s WireGuard mode, plus ExpressVPN’s Lightway, are specifically built to minimize that loss. In 2026 testing, all three stay fast enough for HD/4K streaming and video calls on a normal home or hotel connection.
Can I use a VPN and iCloud Private Relay at the same time on iPhone?
Technically yes, but Apple itself recommends against it — the two systems both try to encrypt and route your traffic, which commonly causes connection failures rather than added protection. Turn off Private Relay in Settings → iCloud while your VPN is active.
Why doesn’t my iPhone VPN let me exclude just one app from the tunnel?
Apple’s iOS doesn’t expose the system-level API that Android apps use for per-app split tunneling, so no iPhone VPN — including NordVPN, ExpressVPN, and Surfshark — offers true app-by-app exclusion. Surfshark’s “Bypasser” is the closest workaround, but it excludes specific websites, not individual apps.
Do I need the most expensive plan tier to get a kill switch on iPhone?
No — all three providers include a kill switch on their standard iOS app, not gated behind a premium tier. Where tiers actually matter is device-connection limits (ExpressVPN) and bundled extras like a password manager or ad blocker (ExpressVPN’s Advanced tier, Surfshark’s One bundle).
