Textopolis is a city within humans' smartphones containing messaging apps. This will serve as The Emoji Movie's setting wherein a majority of the main characters reside.
Hidden within the messaging app, Textopolis is a bustling city where all your favorite emojis live, hoping to be selected by the phone's user.
When someone is texting, because no one knows if the user will choose an emoji, they go to a room where emojis are on a small space. Workers tell the user's selected emoji, and said emoji needs to prepare for the scan, and the scan taken will be what will be sent.
