Users can install Android applications that are unavailable in their region by using a VPN to change their device’s IP address. To download an app like PUBG Mobile, users should connect to a VPN server in a country where the app is available, force stop the Google Play Store, clear its cache, and then reopen it while still connected to the VPN to search for and install the app. If the app does not appear, users may need to clear the Google Play Store data and create a new Google account while connected to the VPN.
