Pokecom is Dimension Number 2's version of a cellphone. Every former human is given one when they enter the dimension, along with their own five digit hexadecimal number, which works as their phone number. Just about every Dimension Number 2 native has a Pokecom and their own number as well. Upon meeting, numbers can be exchanged and registered into Pokecoms. It's possible to keep in contact with many because the Pokecom can keep an infinite amount of numbers in it's memory.
Pokecoms come in many different solid colors, and users are also allowed to edit Pokecom sprites to customize for their characters if they want to. Pokecoms also come in two different designs.
