Do you actually need a VPN on an iPhone?
iOS is a locked-down system and apps cannot see each other's data, but none of that protects the connection between the phone and the network it is on. On hotel or airport Wi-Fi the hotspot operator, and anyone else connected, can see which services your phone talks to and intercept anything not already encrypted, and the phone chatters constantly in the background.
Two things get mistaken for a VPN on an iPhone. The first is the VPN entry in Settings, a client for connecting to a VPN someone else runs, which does nothing until a provider's app or a work profile configures it. The second is iCloud Private Relay, which comes with iCloud+ and which Apple describes as hiding your IP address and encrypting DNS lookups while you browse in Safari. It does not cover other apps, it cannot make you appear to be in another country, and Apple says it is unavailable in some regions.
Location is the other reason. UK bank apps and BBC iPlayer check where the phone is, and from a cafe in Barcelona or a hotel in Dubai they see a foreign address; a UK server fixes that. The App Store is also not the same everywhere: in July 2024 Apple removed VPN apps from its Russian store at the demand of the regulator Roskomnadzor, so install before you fly. If something breaks abroad, 24/7 live chat from NordVPN or Surfshark is quicker than guessing.
What a VPN does and does not do on an iPhone
A VPN app encrypts everything leaving the phone and routes it through a server you choose, so the hotel network sees only scrambled traffic to one address and websites see the server's location rather than yours. On an iPhone that covers Safari, Chrome, WhatsApp, banking apps and the background syncing that Private Relay leaves exposed. A kill switch stops traffic if the tunnel drops, which matters when the phone hops between Wi-Fi and mobile data.
It does not scan for malware, it does not stop you tapping a phishing link, and it will not improve a weak signal. Captive portals are the usual snag: you have to accept the hotspot's terms page before the VPN can connect, so pause the kill switch for that minute. Both picks carry a 30-day money-back guarantee, so test on your own phone before you travel: NordVPN for a shorter trip, Surfshark if the iPhone is one of many devices you carry.
Recommended VPNs for iPhone
NordVPN, best for short trips and month-by-month plans
It is the one for you if you are covering yourself, or you and a partner, and want something simple to run and easy to forget about. One plan covers 10 devices, and the apps are quick to install and easy to switch off and on as you need. Plans run by the month, the year or over two years, all with a 30-day money-back guarantee.
Surfshark, best for long stays and unlimited devices
It is the one for you if one subscription needs to cover everyone. Connections are unlimited, so your iPhone, every other device you travel with, and anyone you share a place with, all run on the same plan at once. That suits a stay that stretches to months rather than weeks. It sells the same three terms and adds bonus months on the longer two, with the same 30-day money-back guarantee.
Server networks and speeds on iOS
NordVPN's own site describes thousands of servers across 225 locations, and Surfshark publishes a country-by-country list that covers every region a traveller is likely to land in. On an iPhone the protocol matters as much as the count: both apps default to a WireGuard-based protocol (NordVPN calls its version NordLynx), which reconnects quickly when the phone switches from Wi-Fi to 5G and is light on the battery. NordVPN's support pages say its iOS app needs iOS 17 or later. Connect to a server in the city you are in for everyday use and switch to London only when you need a UK address.
How to choose between them
The differences that matter fit in one table, and the last two rows are there to name two promises you should not believe from anyone, us included.
| Feature | NordVPN | Surfshark |
|---|
| 1 month | $14.99 | $16.45 |
| 1 year plan, total upfront | $65.88 (12 months billed) | $50.85 (15 months billed) |
| 2 year plan, total upfront | $94.23 (27 months billed) | $67.23 (27 months billed) |
| Devices per plan | 10 | Unlimited |
| Kill switch and auto-connect | Yes | Yes |
| Independently audited no-log policy | Yes (2025) | Yes (2025) |
| Money-back guarantee | 30 days | 30 days |
| Guarantees access to any blocked site, anywhere | No | No |
| Makes slow Wi-Fi faster | No | No |
On a single month NordVPN is cheaper. Over a year or two Surfshark is. On everything else the choice is about shape rather than money: 10 devices and a simple setup on one side, unlimited devices on the other.
Setting up your iPhone before you travel
Do the setup at home, on Wi-Fi you trust, before the airport. Install NordVPN or Surfshark on your iPhone, sign in, and connect once to confirm everything works. Then turn on two settings both apps include: the kill switch, which stops your traffic travelling unprotected if the VPN drops, and auto-connect, which brings the VPN back up when your connection returns.
On an iPhone, install from the App Store at home, open the app once and approve the prompt to add a VPN configuration, which is what makes the toggle appear in Settings. Turn on the kill switch and auto-connect for untrusted Wi-Fi, and save a UK server as a favourite. If you later want the VPN off, disconnect in the app rather than flicking the Settings switch, because auto-connect will turn it straight back on. Leave Private Relay on if you have iCloud+; the two do not conflict when the VPN is connected.
Final recommendation
An iPhone does not need a VPN because iOS is insecure. It needs one because hotel and airport Wi-Fi are, and because the built-in client and Private Relay are not travel tools. For a shorter trip with a phone, a laptop and perhaps a tablet, NordVPN is the pick: a quick native iOS app, NordLynx for fast reconnects between networks, and ten device connections.
If you travel with a family's worth of phones and tablets, or you are abroad for months as a remote worker, Surfshark is the better value. Unlimited devices covers every iPhone, iPad and TV box on one subscription, and the iOS app is a straightforward App Store install.
