We would have no way to track your device and neither would you using that information. Not unless you had the phone registered with a tracking service, or had a tracking app on it.
You can try calling your carrier/service provider and see if they can give you at least a general idea of its location or where it was last used. You should also get them to turn off the service so no one runs up your bill. Lastly. I would seriously suggest changing all your log in information and passwords to anything you ever accessed from the phone. Before who ever has it accesses your accounts.
