The most popular and probably easiest way to do so is by downloading the APK code for Pokémon Go. It’s rather simple to find the APK (how else did you find this story?) but you should know the risks if you plan to bypass the lock and download Pokémon Go early. Also, if you change your app store to another country you’ll lose your progress in the game once your country does receive the mobile game.
But worry no more. You can download and play pokemon go international without any risk and its free here!
