This game is defunct. Do note the game no longer works at all without modifications. This is most likely due to the game's servers being shut down (as of January 20, 2026). As a result, further official developments with the game are unlikely to happen.
To do:
Figure out how to extract the file formats in the game.
SB and SB3D file formats for the 3D models and textures.
The .bnk files for the audio.
The Sims Mobile is basically The Sims 4 ported to mobile with various downgrades, such as restricting you from doing anything once you run out of energy unless you spend money. It also uses voice clips from The Sims 3 instead of 4, for some reason.
The game's servers were shutdown on January 20, 2026, making it unplayable.
