Pokemon Diamond and Jade (GBC), Pokémon Fan Game Wiki

Pokemon Diamond and Jade are bootlegs of the game Keitai Denjuu Telefang 1 Power and Speed versions (Diamond being Power and Jade being Speed). The game plays like a typical Pokemon game with a few differences. Instead of having a party of six creatures (which are called Denjuu in the original game), the player will have one Denjuu with them and in battle they can use a mobile phone like device (called a D-Shot in the original) to call in up to two more Denjuu depending on the D-Shot's coverage.
