VPN for iPhone: what it does and how to turn it on
A VPN on your iPhone sends your internet traffic through a server before it reaches the website or app you are using. The network you are on sees only an encrypted stream to that server. Here is what that changes in practice, and how to switch it on in one tap.
What changes when the VPN is on
Two things. First, the Wi‑Fi or mobile network you are connected to cannot read your traffic or see which sites and apps you use. It sees one encrypted connection to a VPN server, nothing more. Second, the sites you visit see the address of that server instead of your own, so they know the country of the server, not your location on the map.
What a VPN does not do: it does not make you invisible, it does not stop a site from recognising you once you log in, and it does not replace the lock on your phone. It protects the path between your phone and the internet, and that is exactly the part that is exposed on a network you do not control.
When it is worth turning on
On public Wi‑Fi in a cafe, airport or hotel, where anyone on the same network can watch unencrypted traffic. On a network that blocks or slows down the apps you rely on. When you are abroad and want your usual apps and sites to behave as they do at home.
The rest of the time you can leave it off. sNova counts only the bytes you send through it, so nothing is used while it is off.
Setting it up on iPhone
Install sNova VPN from the App Store and open it. Choose a plan — the annual one starts with a free trial — and confirm with your Apple Account. Then iOS asks for permission to add a VPN configuration; tap Allow. That is the whole setup. There is no account to create and no email to confirm.
To connect, swipe the control at the bottom of the screen. The ring shows how long the session has run. Leave the country on Optimal and sNova picks the fastest server, or tap the country field and choose a country yourself.
To turn it off, tap the connected control. You can also see and remove the configuration in Settings › General › VPN & Device Management at any time.
Free trial and Unlimited
Unlimited has no traffic limit and opens every country we offer. New subscribers to the annual plan start with a free trial; its length and the price after it are shown before you confirm. You can cancel anytime in your Apple Account.
Questions
Does a VPN drain the iPhone battery?
Slightly, because traffic is encrypted on the phone. In everyday use the difference is small; the screen and the radio use far more.
Can I use sNova on iPad as well?
Yes. The app runs on iPhone and iPad with iOS 17 or later. An Unlimited subscription follows your Apple Account; on the iPad, tap Restore Purchases in Settings.
Does sNova see which sites I visit?
No. The servers do not log visited sites or inspect content. What we keep, and why, is listed in the Privacy Policy.
