The only way to locate it is with software, such as BlackBerry Protect, which would have to be already installed before the phone went missing. I'm assuming since you haven't mentioned it, it's probably not on your phone so you have no way of tracing your phone.
One thing you should do is call your carrier and report the phone stolen IMMEDIATELY. That way, they can cancel your SIM card and no charges can be made against your account. Notifying the police is also a good idea. When or if you get your phone back or get another one, make sure to install BlackBerry Protect www.blackberry.com/protect on it.
I hope that answers your question.
