Keitai Denjuu Telefang 2 is the sequel to the first Telefang game for the Game Boy Advance. Taking place in a different part of the Denjuu world from the first one, this game shares some qualities with Telefang 1. The battle system is similar, as is the gathering-phone-numbers system, but a good deal of things are quite different from the original.
The game follows a blue-haired protagonist (named by the player but original called Kyou) as he journeys on his quest to become a T-Fanger. Along the way, he encounters Diablos, who is not content with humans entering the Denjuu universe and so is killing off the Antenna trees, thereby cutting off access to the human world.
With only one antenna tree in existence, that tree was the only entrance left from the human's world to the Denjuu's world. The player, naturally, must stop him before he is stuck in the world forever. 
Changes from Telefang 1Edit
- Main article: Differences between Telefang 1 and Telefang 2
There have been significant differences in the two games, Telefang 1 and 2.
- The sprites were redrawn
- The background music was changed
- New Denjuu were introduced
- Move types were introduced, and a Denjuu which has a type disadvantage would not necessarily lose if it has good moves.
- In Telefang 1, the starter partner would be different in both versions (Crypto and Fungus), while in Telefang 2 it would be Rex for both versions.
- The new Denjuu mod evolve differently. Unlike the old Denjuu, their habitat type would change as they mod evolve. For mod evolved Denjuu that return in Telefang 2, their types have changed to reflect this pattern.
- Some Denjuu evolve differently, with many evolution chains drastically shortened or even completely removed.
- In battle, each Denjuu has a friend that is specific to a Denjuu, which randomly appears and attacks the opponent.
- In Telefang 1, wild Denjuu cannot be seen before battling them (similar to Pokémon), except at some specific areas. In Telefang 2, wild Denjuu can be seen in the overworld, and coming close to one will cause a battle to start (similar to Zelda II or Super Mario RPG).
This game was only ever released in Japanese; however, there are hackers who have been able to edit the hexadecimal values in the ROM images to release an English patch. There was also a 100% translated into English bootleg called "Pokémon Sapphire" for GBA (however, the cardridge doesn't work on NDS).
