So you think you beat everyone in the game? Well, luckily in Gold & Silver Nintendo decided to let you re-battle some opponents you already beat in the game. The only catch is that you need to get their phone number so they can call you when they want to battle. Unfortunately it gets very annoying when they keep calling you so you'll usually delete their number. However, later if you want to battle some more you might forget where they were located. Here's a list of all the people who will exchange phone numbers.
