There is no way we could track your device. If you had one of the many apps that can help you track it, you might be able to located it, but otherwise it is not possible.
You might try contacting your service provider/carrier and see if they can track it. If not, they would be able to turn off the service so that you aren't charged for anything the other party does. Also I would highly suggest that you log into any account you accessed from your phone and change all the passwords.
