From the name itself, a VPN (Virtual Private Network) is simply a collection of devices that can communicate with each other 'secretly' on the Internet. There are also different kinds of VPNs, as well as various setups and configurations. If you are not a tech-savvy person, the structure of a VPN might be boring and complicated for you. However, it is very important that you understand how VPN works so you know how it can help you be more secure while you are enjoying your iPad or iPhone.
VPN for iPhone
First of all, Apple has its own security features against robbers and identity theft. Apple CEO Tim Cook also has promised to improve the current iOs version on the way the company handles users' private data when they log in to iTunes and iCloud. But while this bright idea is a good sign of showing concerns to their customers, it is still not enough. After all, you didn't buy an Apple device just because you are a die-hard Apple fan. You bought it because you also want to surf the web and visit some websites.
And as mentioned earlier, iPhones and iPads can be used anywhere especially in a non-secured Wi-Fi zone. These days, they are almost everywhere such as in cafes and restaurants, hotels, airports, train stations, and others. Apparently, this is when a VPN can protect you, the way Apple is not capable of doing. With a VPN, you can browse websites anonymously from your mobile device. You will be provided a new IP address, and therefore hides your real IP address as well as your geo-location. And yes, it is legal to use VPN.
But this is not the only benefit of using VPN for iPhone and iPad. VPN traffic is also well encrypted, which means your online activities are hidden too. This means no one or system can easily intercept you data, not even hackers. This is the greatest advantage of VPN over other ways of surfing the Internet anonymously. This is also why many people use VPN to unblock restricted sites when they are in a country that imposes strict Internet censorship, like China and in the Gulf region.
However, not all VPN providers are the same. There are the free VPNs and the premium ones. But paid VPN are far much better than the free ones in all aspects except of course that you need to pay. Note also that a free VPN needs money to survive, and they get this from advertisements that will appear right in front of your face as you activate their service. Come to think of it, don't you think it's weird that you can afford to buy expensive devices and yet you are hesitant to spend a few bucks for your online security?
