[CHARMANDER418]

Ok so im not sure if this is where i should post this or not, so sorry if its in the wrong place.

I want to get into wireless tradeing, so what do i need to be able to trade wirelessly? O and i have platinum if that matters any.

Thanks for any help and again sorry if this is in the wrong place
