The C-Gear lets you communicate with other Trainers, as well as a number of other functions, using a variety of communication methods.
Use Pass Power in the Entralink!
Visit the Entralink to communicate with other players. It's a large area with a variety of places to check out, including the Entree in the center. When you connect with other players via Entralink, you can use Pass Powers to bestow useful effects on the other players. In fact, when you use a Pass Power, it will affect all nearby players. But you need Pass Orbs to use Pass Powers, and to get those, you must complete a mission in another player's world!
In addition to connecting with other Trainers via Nintendo® Wi-Fi Connection and DS Wireless Communications, you can even use Infrared Connection to communicate.
