Before changing devices, link your game data to a Google Account, Apple Account, or Nintendo Account within the game. When you launch the game on your new device, you can continue playing Pokémon Champions with your existing game data by logging in with the same account linked on your previous device.
Important Note for Android Users:
Please be aware that data transfer using an Apple Account is not supported on Android devices. If you are switching to an Android device, please ensure you have linked a Nintendo Account or Google Account on your old device before changing devices.
