There are two different starting points: using a VPN provider’s app, or connecting with settings supplied by your workplace. The VPN menu on a phone or computer does not provide a server or subscription by itself.
How Does a VPN Work, and What Is It For?
- An app or VPN profile connects your device to the chosen server.
- Traffic covered by the tunnel is encrypted on its way to that server.
- A personal VPN service forwards internet traffic onward; the website generally sees the VPN exit address.
For example, a VPN you trust can limit the traffic information visible to a hotel’s Wi-Fi network. A company VPN may instead give you access to internal files or applications. Mozilla’s explanation describes the tunnel between your device and the provider.
A VPN does not replace HTTPS. HTTPS separately encrypts the connection between your browser and the website. Check the address and take certificate warnings seriously even when the VPN is connected.
What Changes When a VPN Is On?
Scroll sideways to read every column. Keyboard: focus the table and use the arrow keys.
| Expectation | What Actually Happens |
|---|---|
| Change my IP address | A connection routed through the tunnel generally uses the VPN server’s public IP. Excluded applications do not necessarily share that coverage. |
| Hide my location | The location inferred from your IP can change. GPS information you allow your phone to share does not. |
| Make me unrecognizable | Signed-in accounts, cookies and browser fingerprints can still identify you. |
| Make every connection safe | A VPN does not fix a fraudulent login page, a malicious download or a weak password. |
You still need to trust someone, including the VPN operator. EFF’s selection guidance considers privacy policies alongside the limits of anonymity. Do not assume a browser extension covers the entire device either; check which traffic the product routes.
How to Start Using a VPN
For personal use, you can start with the provider’s official application. For work, use the app or profile supplied by your administrator. Do not fill in random server details found online.
Using a VPN on Windows
- Download the Windows application from the provider’s official site and install it.
- Sign in, choose a suitable server and select Connect.
- Check that the application reports a connected state. Opening its window is not enough.
If you were given a manual profile, use Settings → Network & internet → VPN → Add VPN. Get the server address, VPN type and credentials from the service or administrator. Microsoft documents this method; not every commercial VPN configuration works with the built-in client.
Using a VPN on Android
- Install the provider’s Google Play application, checking the developer name.
- Sign in and start the connection. Read the app name in any VPN permission request.
- Check the application’s connected state and Android’s VPN indicator.
Profiles are usually under Settings → Network & internet → VPN. Menu names vary by manufacturer; search Settings for “VPN” if needed. Android’s help page separates connecting, editing and disconnecting.
Using a VPN on iPhone
- Install the provider’s App Store application and sign in.
- If connecting prompts you to add a VPN configuration, check the app name and approve the request for the service you intend to use.
- Return to the application and check the connection state.
Proton’s iOS instructions illustrate this permission prompt. Installed organizational profiles appear under Settings → General → VPN & Device Management. Ask your administrator before removing a work or school profile: Apple explains that associated settings and data can be deleted too.
How to Check and Disconnect the VPN
After connecting, compare your address with the earlier result from the same IP-checking tool. Open a website and an application you normally use. If needed, run the provider’s DNS/WebRTC checks. A changed IP alone does not establish that every application uses the tunnel.
To stop the connection, use Disconnect in the VPN app. Closing a window or swiping an app away on a phone does not always disconnect it. Check the connection state again.
If it reconnects automatically, inspect automatic connection, always-on or on-demand settings. If manual disconnection also blocks internet access, read the active protection mode: Mullvad’s Lockdown mode deliberately does this. Do not change enforced settings on a managed device.
Are VPN Types and Protocols the Same Thing?
No. A personal VPN routes your internet connection through a service. A remote-access VPN connects a device to an organization’s network; a site-to-site VPN connects networks to each other. Cisco describes the organizational distinction.
WireGuard, OpenVPN and IKEv2/IPsec are protocols that determine how a connection is established. A name alone cannot identify the fastest choice on every network. Start with the application’s recommended setting; for work connections, follow the supplied configuration.
If the VPN Will Not Connect or Runs Slowly
- It will not connect: check ordinary internet access, account status and application updates first. Contact your support team for a work account.
- It connects but runs slowly: try another suitable server on the same network. Distance, congestion and routing affect the result; one speed reading is not enough.
- An application or printer stops working: check local-network access and any split-tunneling settings that exclude apps from the tunnel. An excluded application may fall outside VPN protection.
- A site remains unavailable: a VPN does not guarantee access to every service. Do not bypass certificate warnings or disable security software as a workaround.
Free or Paid: What Should You Check?
Price alone does not establish safety. Check a free plan’s allowance and server selection, or a subscription’s total payment and renewal terms. Either way, examine privacy practices, device support and interruption behavior.
When you are ready to choose a service, the plan comparison and Mullvad measurements provide the next step. Start by making sure you can connect, understand what is covered and disconnect when you intend to.
