Avoid Public Wi-Fi Networks
While having free Wi-Fi sounds great, public networks are a serious security risk for your iPhone and all other devices.
The reason is that public Wi-Fi networks can be accessed by anyone, including potential hackers. Since they don’t require any type of authentication or offer any built-in encryption, anyone who knows enough can use public Wi-Fi to intercept data coming from your iPhone.
Moreover, there are times when you don’t know who’s behind the public network itself. The network owner could see your browsing history, making it completely unreliable.
Needless to say, public Wi-Fi networks are very risky, and you should avoid them at all times. Whether it’s big corporations or small hackers, your data is at risk. If you absolutely need to use one, be sure to turn on a VPN so you have an extra layer of security.
