Unlike most other informational items, the Cell Phone does not double as an accessory, and cannot be equipped in accessory slots. It instead functions solely from the player's ordinary inventory slots, which puts it into the tool category.

While the inventory screen is open, Cell Phone information is hidden. Instead, an icon is displayed for each information type, each of which can be clicked to toggle their display on or off.

In multiplayer, information from the Cell Phone will be shared with other nearby players on the same team.
