Despite claiming that the Animal Crossing mobile game would release on November 22, it seems Nintendo has allowed the game to release slightly ahead of schedule. Animal Crossing: Pocket Camp is now downloadable on both the Google Play and App Store, in North America, UK, Japan, and Australia. Servers appear to be fluctuating between working and resulting in error messages. The game is always-online, so you must have a constant connection to play it.
