Yeah but if you don't know your friend code, we can't trade.
Check your Bag and under Key Items tab, see if you have item called "Pal Pad" you can see your friend code from there.
Or if you don't have Pal Pad yet, go to nearby Pokemon Center and go to basement and the person on the basement will give you Pal Pad.
Once you have the Pal Pad, tell me your friend code and you add my friend code and then we can trade via Wi-Fi.
