A VPN APK is a VPN app available as an Android Package Kit (APK). On an Android device, you can download apps from outside of the Play Store, and one such way is by transferring or downloading APK files to your device.. APK files also allow you to download Android apps onto devices that run Android but don’t have Play Store installed, such as the Amazon Kindle Fire tablet. You can also download an app using an APK if it is blocked in your country.. Met onze VPN APK kun je de ExpressVPN-app downloaden op je Android-toestel zonder dat je de Play Store hoeft te gebruiken.
