how do I sell my used cell phone (BlackBerry)?

I have this blackberry model : 9630, it is deactivated by verizon because I got a new phone.
I want to sell it on craigslist and I already restored it back to the original form (except it still says my number)
Do I need to take out anything in the back of the phone? obviously keep the battery in the phone but what about the other two cards.
Also how does the buyer activate the phone?
