When Does Pokemon UNITE Come Out on Mobile?
Pokemon UNITE will come out on mobile sometime this year in September. Stated on Pokemon UNITE's official website: "Pokemon UNITE will be available on mobile devices in September. Cross-platform play between Nintendo Switch and smartphones is planned, which will allow players on both platforms to battle together and against one another."
The website goes on to say that progression between your Nintendo Switch data and the newly downloaded mobile app will indeed be shared, meaning you don't have to start over again when you want to play on your phone, if you already played on your Switch. This cross-progression will be achieved by having the player log in to either their Nintendo account, or their Pokémon Trainer Account.
Keep an eye out on the Google Play Store and App Store for Pokémon UNITE sometime in September 2021.
