The Rotom Phone (Japanese: スマホロトム Smartphone Rotom) is an electronic device found in Galar in Pokémon Sword and Shield. It is a smartphone that is enhanced after being possessed by a Rotom. It is shown to be popular amongst Trainers across multiple Pokémon canons, and can host a multitude of functions and applications, including a Pokédex.

The Rotom itself can also power the motor in the Rotom Bike, allowing the player to travel faster, and after an upgrade, over water as well.
