Surfing the web on a public WiFi can be dangerous business, opening your iPhone or iPad up to spying eyes. To avoid that, you could use a VPN to stay private and anonymous.
A VPN also hides your location online, which can allow you to access blocked content and blocked sites such as US Netflix when you are in the UK or BBC iPlayer when you are abroad. Here we talk you through the best iOS VPN options.
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.

It's important to note that, as of 17 July, Apple has begun banning VPN-based ad blockers from the iOS App Store as part of its guidelines, as spotted by the developer behind Adblock and Weblock who has been affected by the ban.
However, the apps mentioned here are unaffected, and even those that have been affected will quickly adapt to ensure that they are allowed back onto the App Store and follow Apple's guidelines.
Additionally, VPNs have been banned in China and Russia, and as a result Apple has been removing VPN apps from the iOS App Store in those countries.
Our pick of the best VPN for iPad and iPhone is NordVPN. Based in Panama, NordVPN is outside of the jurisdiction of the '14-eyes'.
There are more than 1,000 servers available across 61 countries, and encryption levels are among the highest available in a VPN.
You can connect to up to six devices at one time with your NordVPN account, which offers pricing starting at around £4 per month.
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 iPad and iPhone.
You can connect to three devices at once, and there's no limit to bandwidth, server switching or speed.
The recommended plan ExpressVPN plan is the year-long subscription, which normally works out at $8.32 per month and saves you 35% over the less committed month-long option at $12.95. However, right now there's a special offer that will get you 15 months for the price of 12, and this works out at $6.67 per month, which is just over £5.
There is also a 30-day money back guarantee with no questions asked.

Another great option is Pure VPN. 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 500 servers available across 140 countries.
Its iPhone and iPad app is simple and smart, and lets you tailor your connection based on the internet activity you intend to do.

CyberGhost is another great option, and it's also brilliantly priced. It's headquartered in Romania, which is outside the 14-eyes group of countries that share signals intelligence (find out more here).
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 1000 servers available to connect to over 30 different countries, although they don't always work with Netflix US.
You can get CyberGhost for $2.90 per month if you sign up for two years (you'll pay $69.60 upfront), but if you want to commit to just one month it'll be $10.49 per month.

Private Internet Access
Private Internet Access is another of the best VPNs that also comes a low price tag.
At around £3 per month, it offers anonymous browsing and access to blocked content including Netflix US.
The iPhone and iPad app is incredibly simple and easy to use, and it's also super-speedy. A solid option.

Another option that offers lots of great features is IPVanish, which is both good-looking and easy to use. It has 750 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 per month.

TunnelBear offers a limited free version of its VPN service that you can try before you commit to the year-long option for $59.88 which works out at $4.99 per month, or a one month option for $9.99.
Once signed up, you can connect to up to five devices simultaneously, and there are apps available for iPad, iPhone, Android, Mac and PC.
