What is VPN on iPhone & How to Set it Up in 2025

Key takeaways:

A VPN encrypts your data and keeps your iPhone activity private from hackers, ISPs, and advertisers.
The best iPhone VPN has AES-256 encryption protocols in place, allows access to restricted content, and bypasses censorship.
Using an iOS app from the App Store makes setting up a VPN connection on an iPhone quick and easy.

The internet isn’t always a safe place, not even for an iPhone. Just like we have thieves and scammers in the real world, there are similar equivalents on the internet. Hackers, advertisers, and even internet providers can track your online activity for different purposes.

That’s why using a VPN for iPhone is a smart move. A VPN (virtual private network) protects your data, hides your location, and masks your IP address. Even if you don’t use public Wi-Fi on your iPhone when you go somewhere, it’s just as beneficial to use a VPN at home.

When we carry our phones every day, they get exposed to multiple Wi-Fi connections and public networks. Such connection points are often fertile ground for hackers and cybercriminals who aim to intercept your traffic.

To protect yourself from such threats, you need a VPN on your iPhone. Find out what it is and how to get it.

What is a VPN on an iPhone?

A VPN is a tool that creates a secure VPN connection between your iPhone and the internet. It hides your iPhone's IP address and encrypts all the data you send and receive.

It's like putting your data in a blind spot where no one can see it. Not hackers, not advertisers, and not even your internet provider can track what you do.

When your iPhone is connected to a VPN, it sends your traffic on a private path through VPN servers. It keeps your data safe from prying eyes. As a result, you get increased security, enhanced privacy, and, as a bonus, access to geographically restricted content.

How to Set Up a VPN on Your iPhone

Using a Dedicated VPN App

The easiest way to set up a VPN is through a dedicated iOS app. Here's a guide that will help you set up a VPN on your iPhone:

Open the App Store on your iPhone.
Search for a trusted VPN app, like CometVPN.
Check the reviews to make sure other people found it useful.
Download and install the app.
Open the VPN app and follow the account creation instructions.
Choose a server and tap “Connect” to put your iPhone under VPN protection.

That's it, your iPhone now has a VPN. These 6 steps shouldn't take you more than 5 minutes to set up a private and secure browsing experience on your iOS device.

Manual Configuration

If you prefer not to use an iOS app, you can manually configure a VPN on your iPhone. Just follow these steps:

Open iPhone settings.
Tap “General” and select “VPN & Device Management”.
Tap “Add VPN configuration”.
Enter the VPN details found in your VPN provider.
Tap “Done” and switch on the VPN connection when needed.

Keep in mind that some of the names in the settings may vary based on your iPhone model and language preferences.

Why Use a VPN on an iPhone?

Security and access are the two main reasons why people use a VPN on their iPhone. Once you have a VPN, you can even disable private browsing on your iPhone since you’re already as protected as a regular person needs to be.

Enhanced Security on Public Wi-Fi

Public Wi-Fi networks, like those in coffee shops, airports, or trains, are far from safe. Hackers can grab your private information, snatch your login details, or sneak harmful code onto your iPhone.

Using a VPN connection encrypts your data, which protects your device from cyber threats. It matters most if you're constantly jumping on public networks whenever you go out.

A VPN stops others from watching what you do online. For example, your internet service provider could track your website visits and make money by selling this information to advertisers.

Then, your iPhone will get bombarded with ads with every step you take. A VPN prevents that from happening as your ISP can no longer trace your online activity back to you.

Access to Geo-Restricted Content

Have you ever hit a wall trying to watch your favorite show abroad? Many streaming sites lock their content to specific countries due to licensing terms.

With the best VPN, you can pick a new virtual location and unlock content from any place. A VPN allows you to get more choices to watch shows, movies, sports, and websites on your iPhone.

Bypassing Censorship

Some governments block access to social platforms, news sites, and other online websites. A VPN helps you bypass these walls by connecting your iPhone to servers in other countries, which opens up the whole internet for you to explore.

Key Features to Look for in an iPhone VPN

If you’re looking to buy a VPN for iPhone, make sure you do your research and select the one that best reflects your needs.

Strong Encryption Standards

Top VPN services protect your data with advanced security protocols such as AES-256. A VPN provider offering this encryption protocol will be one of your best choices since AES-256 is nearly impossible to crack.

If you want to cover your iPhone in advanced protection using this protocol, CometVPN could be one of the best VPNs for your iPhone.

No-Logs Policy

A good VPN should have a strict no-logs policy. This means the provider doesn't store any of your browsing history. Without logs, even if someone requests your data, there's nothing to share. It helps protect your iPhone from data leaks, third-party involvement, and numerous other annoying situations.

High-Speed Connections

Your VPN services should keep up with your needs. Fast servers help you browse, play games, and watch shows without delays. The best iPhone VPN shouldn't slow you down while keeping you safe from online threats.

User-Friendly Interface

A good iOS app should be easy to navigate. The VPN setup should take just a few taps, even for beginners. The best VPN services offer well-designed apps that make connecting to VPN servers easy and simple for all devices, not just iPhones.

Reliable Customer Support

Problems are bound to pop up at times, so round-the-clock help matters, especially if you continuously rely on a VPN to keep you safe. When your VPN on iPhone starts acting up or you need some guidance, there should be a customer support team to help you fix things fast.

Advanced features for VPN phone users

While different VPN providers offer diverse features,we singled out some of the most important ones that you should pay attention to. These features will make your online activities safer and protect you from unexpected disruptions:

Kill switch. It’s present in many premium VPN services, and protects your browsing from accidental VPN outages. In case a VPN stops working, this function immediately blocks your internet access until the connection is restored.
Split tunnelling. It’s a VPN feature that allows you to control how your internet traffic is routed. You can choose which apps or websites use the VPN connection, and which ones connect to the internet directly without going through the VPN.
Wide selection of server locations. It increases the possibility that you will always be able to choose the server with the best capacity or the geographically closest to your location.

Troubleshooting a VPN on Your iPhone

If you’re having trouble with your VPN on iOS, there are several troubleshooting steps you can follow to resolve common issues. Here’s a guide to help you diagnose and fix problems with your connection.

1. Check the VPN Settings Configuration

Verify that the configuration details (e.g., server address, username, and password) are correct if you manually configured the VPN. If using a third-party app, make sure it’s properly installed and that you’re logged in.

2. Restart the VPN Service Connection

Sometimes, restarting the connection can resolve the issue. Toggle the VPN switch off and then on again. If using an iPhone VPN app, disconnect and reconnect within the app.

3. Restart Your iPhone

A reboot can fix various minor issues. Press and hold the Side Button and either of the Volume buttons until the slider appears. Then, slide to turn off your device. Finally, turn your iPhone back on by pressing and holding the Side Button until the Apple logo appears.

4. Check Your Internet Connection

Ensure that your iPhone has an active and stable internet connection. A VPN won’t connect if there is no internet access. Open a browser and try loading a website without the VPN. If the website doesn't load, troubleshoot your Wi-Fi or cellular data. If using Wi-Fi, try switching to Cellular Data (or vice versa) and reconnect to the VPN.

5. Update iOS and iPhone VPN App

Ensure your iPhone is running the latest version of iOS and that your VPN app is up to date. For third-party VPN apps, go to the App Store, tap your profile icon, and scroll down to see if there’s an update available for the VPN app.

6. Switch VPN Servers

If you’re using a VPN app, try switching to a different server. Open your VPN app and select another server location to see if it resolves the connection issue. Some servers may experience high traffic or temporary outages, which can cause connection problems.

7. Check For VPN Provider Issues

Check the VPN provider’s status page or social media for any ongoing service issues or server maintenance. If your VPN provider has customer support, reach out to them for assistance.

8. Reset Network Settings

Resetting network settings can resolve persistent VPN connectivity issues. Be aware that this will also reset your Wi-Fi networks and passwords, cellular settings, and any saved Bluetooth connections.

9. Try a Different VPN Protocol

If your VPN service allows you to switch between protocols (e.g., IKEv2, OpenVPN, WireGuard), try changing the protocol. Open your VPN app or go to Settings > General > VPN if configured manually. Select a different protocol in the settings and try reconnecting.

10. Check Firewall or Security Software

Some network firewalls (e.g., in workplaces or certain public Wi-Fi networks) may block VPN connections. If you’re on a work or public network, contact the network administrator to ensure VPNs are allowed. Try switching to a different network to see if the VPN works.

Final Words

A VPN stands out as one of the most important tools for online safety. It helps shield your private info, lets you watch restricted shows, and gives you peace of mind while browsing the internet.

When selecting the best iPhone VPN for your needs, make sure to get one that runs smoothly, encrypts your data, and fits your daily needs. If you want an iOS VPN you can trust, check out CometVPN: it runs fast, works like a charm, and keeps your iPhone privacy locked tight.

Download VPN for iPhone and enjoy safe browsing on your iPhone at all times.

Frequently Asked Questions

Should I always turn on the VPN on my iPhone?

You don’t have to keep the VPN on an iPhone all the time, but it’s smart to use it when you're on public Wi-Fi or want extra privacy. A proper VPN configuration helps keep a secure connection so no one spies on your internet traffic. It’s especially useful if you want to protect sensitive data while browsing.

How do I know if my VPN is working on my iPhone?

Check your iPhone's settings for the VPN icon at the top of the screen. You can also go into VPN settings and see if it's connected. If your IP address changes after connecting, that means your VPN on an iPhone is working correctly.

Will VPN slow down my iPhone?

Depending on the protocol and server location, speeds may drop. It happens because the VPN encrypts your data to create a secure connection, which adds a bit of processing. But with a fast server and good provider, the slowdown is usually negligible. On the contrary, you may notice lower latency if you connect to servers close to the host location.

Does the iPhone have a built-in VPN?

iPhones don’t come with a full VPN on an iPhone service, but they support built-in tools for manual VPN configuration. You can set it up under VPN settings, or use apps that follow your chosen VPN protocol.

Does VPN work with iCloud Private Relay?

No, they don’t work together at the same time. Private Relay hides part of your browsing info, but if you're using a VPN, it takes over all traffic routing. Basically, what VPN does on iPhone is more complete, since the VPN encrypts everything, not just Safari traffic.

Will a VPN drain my battery?

Yes, a little. A VPN on an iPhone runs in the background, keeping the secure connection alive. That can use more battery, especially if it’s constantly reconnecting or using a heavier VPN protocol.

Is VPN for iPhone legal?

Aside from some restrictive countries, yes. Using a VPN to protect sensitive data and keep your online activity private is completely legal in most countries. Just make sure the services you use follow the laws of your location.
