1 Answer. You can get it from the Devon President in Rustboro City after having delivered his letter to Steven in Dewford Town.
In Pokémon Emerald, the Trainer's Eyes function is replaced by the Match Call function. In addition to the features of the Trainer's Eyes, Match Call allows its user to call anyone who has had their PokéNav registered with the user, similar to the cell-phone feature of the Pokégear.
In Pokemon Emerald you're able to rematch certain trainers and gym leaders through the Match Call feature in your PokeNav. ... Check if the player has at least five gym badges. Check if the player has walked at least 255 steps since the last rematch attempt.
The PokéNav have been introduced in the Pokémon Ruby and Sapphire and Emerald series. The main protagonist obtains the PokéNav after obtaining his/her first gym badge and taking back the Devon Goods that one of the Team Magma/Team Aqua members have stolen.
In Pokémon Emerald, after the player has entered the Hall of Fame, Gym Leaders will offer to rematch the player in a Double Battle via the PokéNav's Match Call.

re: after beating elite 4 where do i go???
It depends on the game. For example, while FireRed and LeafGreen get an Elite Four upgrade, Emerald doesn't.
After you beat the elite 4 in any Pokemon game they get stronger. It doesn't have to do with the lure( lures just make Pokemon spawn).
Steven is in the deepest area of Dewford Town's Granite Cave. Since the second area and afterwards of the Granite Cave is pitch-black, you need to use the Flash HM on a Pokemon to light the way.
Tips
Your Pokemon Must be atleast LVL 45 and have the following move types: Fighting, Electric, Fire, Dark, Ice, Flying. If you need more Xp spend all your Money and just keep challenging the Elite Four Without using Items.
Wallace
It turns out that, in Emerald, you cannot rematch Steven Stone at all. Once you beat him the first time in Meteor Falls, he's gone for good.
Steven M. Stone said: Did they change it because Steven wasn't popular enough or because he didn't play such a huge part in the anime while Wallace had several appearances? Wallace didn't appear in the anime until the DP saga, which was several years after Emerald version was released.
A romance between Wallace and Steven is everything but outright confirmed in the latest Pokémon Masters update.
