Surfing the web on a public WiFi can be dangerous business, opening your iPhone up to spying eyes. To avoid that, you could use a VPN (Virtual Private Network) to encrypt your internet usage and stay private and anonymous online.
In this article we talk you through the best iPhone VPN options. We have a separate article that explains how to use a VPN on an iPhone here.
It's important to note that it is against Netflix, BBC iPlayer and other blocked content's terms and conditions to access them using a VPN, so proceed with caution as you risk getting your account blocked.
If you're concerned and want more advice about using a VPN, read our VPN buying advice here. You might also want to check out our round-up of the best VPN deals, as well as our charts that list the best VPN for Chrome or the best VPN for Android.
There's no doubt that using a VPN can sound like a bit of a daunting and confusing thing to do with lots of technical jargon, but actually they tend to be really easy to install and start using, with no previous knowledge or technical expertise required.
Best iPhone VPN apps reviewed
Our pick of the best VPN for iPhone is NordVPN. There are more than 5,200 servers available across 62 countries, and encryption levels are among the highest available in a VPN.
Based in Panama, NordVPN is outside of the jurisdiction of the '14-eyes' (a group of countries that have agreed to collect, analyse and share information, much of which involves internet activity).
You can connect to up to six devices at one time with your NordVPN account, which offers pricing starting at around £3/US$3.99 per month if you take advantage of the two year deal.
Supported devices include iPhone and iPad, but also Mac, Windows, Linux and Android.

Another popular and trusted VPN option is ExpressVPN, which offers apps for all operating systems including iOS, which means you can use it on your iPhone.
There are more than 2,000 servers available across 94 countries. You can connect to three devices at once, and there's no limit to bandwidth, server switching or speed.
The recommended ExpressVPN plan is the 15 month subscription, which works out at $6.67 (around £5.10) per month and saves you 49% over the less committed month-long option at $12.95 (around £9.80).
There is also a 30-day money back guarantee with no questions asked.

Goose VPN is also a good option if you're looking for a VPN for your iPhone. It's fast and easy to use, with a simple interface perfect for new users.
There's a 30 day free trial available, after which the subscription costs as little as £2.99/$4.17. That's for 50GB, though, which might not be enough for all users. The one year plan without the 50GB limit is £4.99/$6.97 per month.
There aren't huge numbers of servers and countries available via Goose VPN. There are just 27 countries available and 77 server locations. We'd recommend taking advantage of the trial to check whether the server locations you require are available.

TunnelBear is a solid, fast and affordable VPN that works well on iPhones. It's easy to use and is ideal for families and people on the move.
It works with Netflix and other streaming services, offers a kill switch and five simultaneous connections.
The downside is that there are fewer countries available to connect to than other VPNs listed here, with only 20 to choose from.
There's a limited free option available, but the best plan is the yearly plan that costs £3.65/$5 per month.
Another great option is PureVPN. It's a popular and trusted choice, and it's competitively priced too.
PureVPN includes a built-in auto-redial that will automatically reconnect should your connection drop for uninterrupted browsing, and there are more than 2,000 servers available across 140 countries.
Its iPhone app is simple and smart, and lets you tailor your connection based on the internet activity you intend to do.
To use it, you'll need to sign up to a subscription package starting at $2.95 (around £2.33) per month for two years. The money-back guarantee is seven days.

CyberGhost is another good, well-priced option. It's headquartered in Romania, which is outside the 14-eyes group of countries that share signals intelligence.
One of the great things about CyberGhost is its ease-of-use. It's simple and intuitive, and does lots of the hard work for you. There are more than 2,790 servers available to connect to 60 different countries.
You can get CyberGhost for £2.66/$3.50 per month if you sign up for three years.

IPVanish offers lots of great features, and is both good-looking and easy to use. It has 1,100 servers in 60 countries.
It's going to appeal to beginners, as it's one of the most intuitive VPNs we've used, but it does have one downside and that is that it's located in the US. That's not a problem for most casual users, but if 100% privacy is your main concern then you might want to look elsewhere. The company does promise that it doesn't keep any logs, though.
IPVanish costs around £5/$6.49 per month and you can sign up for it here.

VyprVPN offers value for families looking for multiple simultaneous connections. If three connections is enough, you're looking at £3.63/$4.79 per month for a year. It's £4.79/$6.32 if you need five.
There are more than 700 servers available to connect to worldwide, and it's quick and easy to set up a high quality connection. You'll find a kill switch to protect your data should the VPN connection fail, and the iPhone app is simple to use too.

Private Internet Access
Private Internet Access is another of the best VPNs that also comes a low price tag, and it has one of the highest server numbers at more than 3,000. That is across 33 countries rather than the wider spread from some rivals, though.
At less than £2.05/$3 per month for a two year subscription, it offers anonymous browsing and access to blocked content including Netflix US so is a recommended VPN for iPhone.
The app is incredibly simple and easy to use, and it's also super-speedy.
