The switch in Settings needs an app behind it
The VPN entry in iPhone Settings is an empty slot: it does nothing until an app fills it. Install a free client such as Streisand or V2Box from the App Store, paste your ViewPoint VPN key into it and allow iOS to add the configuration. From then on, the switch routes every app on the phone through an encrypted tunnel.
Clients that take the key on iPhone
- Streisand: free and minimal, a good first choice.
- V2Box: free, also available for iPad and Mac.
- Hiddify: free, with the same layout as on Android and Windows.
- Shadowrocket: a paid app with detailed controls, for people who like settings.
Setting it up
- 1
Install one of the clients from the App Store.
- 2
Open the Telegram bot on the phone and take the five free days.
- 3
Copy the vless:// line the bot sends, or open the QR code.
- 4
In the client, import from the clipboard or scan the code.
- 5
Tap connect and allow iOS to add a VPN configuration.
- 6
Look for the VPN badge in the status bar to confirm it is on.
Settings that matter on iOS
Turn on the client's auto-connect or on-demand option if it has one, so the tunnel comes back after the phone sleeps. iOS can pause the tunnel after long idle periods to save battery; one tap reconnects. To confirm it works, compare your IP address with the key on and off.
To remove everything later, delete the client or the configuration under Settings, General, VPN and Device Management.
On hotel and airport Wi-Fi
Join the network, finish its login page with the key off, then switch it on. If the login page never appears, disconnect and open any plain website to trigger it.
This one habit fixes most of the "VPN broke the Wi-Fi" moments travelers run into. While you are in Wi-Fi settings, open the network and check whether Private Wi-Fi Address is on: it gives the hotel network a different hardware address than your home network sees, so the phone is harder to recognize from one network to the next.
What the tunnel does not change on an iPhone
Apps that use Location Services still see where you are, because GPS and nearby Wi-Fi tell the phone its position directly. Apps you are signed into still know it is you. And the tunnel does nothing about a malicious app already installed. What it does change is what the local network and your carrier can see: they get one encrypted connection instead of a list of every service the phone talks to.
Before trusting any VPN app
- Check who publishes it and whether that company has a real website.
- Read what data the App Store privacy label says it collects.
- Be wary of free VPNs for iPhone that never state a limit or a price.
- Prefer clients that are open source.
Questions
What does the VPN setting on iPhone do?
It routes all traffic through a tunnel set up by an app. Without an app, it has nothing to do.
Is there a free VPN for iPhone?
The clients above are free. The key itself is free for five days, then paid.
Can I use the same key on an iPad?
Yes. Same clients, same key; it counts as one of your five devices.
Why does the connection turn itself off?
iOS suspends it after long idle periods. Turn on the client's auto-connect option.
Do I need to jailbreak the phone?
No. Every client here is an ordinary App Store app, and iOS shows its own prompt before adding the tunnel.
Will it slow my iPhone down?
Pages load through one more hop, which you rarely notice on a nearby server.
