How to Use the OpenVPN Connect App on Your Android Device to Connect to NordVPN Servers
Android offers APIs for developers to create virtual private networks (VPNs). These apps are able to offer VPN protocols that the built-in client doesn’t support and allow you to connect to an VPN service without the need for complex configuration.
This article explains how to make use of OpenVPN on your Android device to connect with NordVPN servers. It also explains how to manually configure the connection using the NordVPN app and an OpenVPN profile. This is a more complicated method but it allows you to have greater control over the quality of your connection as well as mobile data.
To get started, download the OpenVPN Connect app from the Google Play Store. Then, you must download the OpenVPN configuration files from your VPN provider. These configs include a.ovpn extension and are available via the VPN provider’s website or their live chat support. Once you’ve downloaded the config files, transfer them to your Android device (or PC). You can do this by directly downloading them to your device or using an app like ZArchiver.
Start the OpenVPN application and then tap “+” to add the VPN profile. Select a server and tap “Connect”. Once connected the entire Internet traffic is routed through the secure tunnel to the chosen server. The app will also display the status of the connection and other details on the Status tab. The app has an option to keep the VPN connection in use even when it’s not being used.
