Pokemon Did You Knows?

[Electricmastro]

In the Japanese version of Pokemon Crystal, the Game Boy Color used an ability called "Pokémon Mobile System GB" that connects a Mobile Phone to the Game Boy itself, which allowed special events such as the GS Ball at a Pokemon Communication Center in Goldenrod City. Though it was never done outside of Japan likely because of the scarce of mobile phones in 2001 other than Japan.

It's reminiscent of the GTS, Global Terminal, Wi-Fi Plaza, and the Pokémon Net Center which use worldwide interaction.

In fact, in HeartGold/SoulSilver, the Global Terminal is located in Goldenrod City, which is a possible reference to the old system.
