How to set up an VPN connection on Android
This step-by-step tutorial explains how to set up an VPN connection on Android:
Open the Settings app and tap “More” under Wireless & Networks.
Tap the VPN option on the Wireless & Networks screen.
Tap the + button and provide the VPN’s details. Enter a name to help you remember which VPN is which into the Name field, select the type of VPN server you’re connecting to, and enter the VPN server’s address.
Tap the VPN to connect once you have set it up. You can have multiple VPN servers configured and switch between them from the VPN screen.
You will need the username and password your VPN requires when you connect. However, you can save this account information for next time.
While connected to a VPN, you will see a persistent “VPN activated” notification in your notifications drawer. To disconnect, tap the notification and tap Disconnect.
Starting with Android 4.2, Google included the option to enable always-on VPN mode. When this option is enabled, Android will never allow data to be sent except over the VPN. This can be useful if you are using public Wi-Fi and want to ensure your VPN is always used.
To enable this option, tap on the cog icon next to the VPN name, then toggle the “Always-on VPN” slider.
