iOS-VPN

A VPN encrypts the connection between your iPhone or iPad and the internet. This gives you privacy as it stops your internet provider (and anyone else) from seeing which websites you visit as well as helping to make you anonymous to websites so they can’t track you (unless you sign in to them, of course).

A VPN, or Virtual Private Network, routes your internet activity through a secure, encrypted connection, preventing others from seeing what you’re doing online and where you’re doing it.

The answer to “should I leave a VPN on?” is yes. VPNs offer the best online security, so you should always leave your VPN on to protect yourself against data leaks and cyberattacks while using public Wi-Fi and against intrusive snoopers such as ISPs or advertisers. So always keep your VPN on.

If security is your main concern, you should leave your VPN running while you’re connected to the internet. Your data will no longer be encrypted if you turn it off, and the sites you visit will see your real IP location.

Yes, it would be best to have a VPN on a cellular network because these networks do not have strong encryption unless you use a private network at their backend.
