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. Limited-edition versions of the game included a peripheral called the Power Antenna.
The game follows a blue-haired protagonist (named by the player, but originally called Kyou) as he journeys on his quest to become a T-Fanger. Along the way, he encounters Diabolos, 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 1
- 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, while some old Denjuu were removed
- 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 fusion evolve differently. Unlike the old Denjuu, their habitat type would change as they fusion evolve. For fusion evolved Denjuu that return in Telefang 2, their types have changed to reflect this pattern. Fusion evolution is also reversible in Telefang 2.
- 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, except in 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.
Power and Speed version differences
- The rival and his or her partner Denjuu are different depending on the version. Otome and Gyuun appear in Speed, while Yuu and Doon appear in Power.
- Certain Denjuu can only be found in one version.
- The colour of the D-Shot menu and the skins that the player can buy to customize it are different in each version.
- Main article: Telefang 2 manga
A manga based on the series was serialized in Comic Bom Bom from February to July in 2002. Unlike the manga based on Telefang 1, it was only published in Comic Bom Bom and never re-released as volumes.
To tie in with the release of the game, a promotional T2 logo or Rex mascot keychain were given out at certain Japanese stores. Special Telefang 2 themed issues of Comic Bom Bom were also given out at certain stores and contained a secret phone number to be used in the game.
