No. You could visit your @icloud.com site and click on the Find My Phone app icon to see if it's being detected. It must be online. I don't know if this will work for your.
What To Do If Your iDevice or Computer Is Lost Or Stolen
iPhone, iPod Touch, and iPad
If you activated Find My Phone before it was lost or stolen, you can track it only if it is connected to the Internet by Wi-Fi or cellular. What you cannot do is track your device using a serial number or other identifying number. You cannot expect Apple or anyone else to find your device for you. You cannot recover your loss unless you insure your device for such loss. It is not covered by your warranty.
If your iPhone, iPod, iPod Touch, or iPad is lost or stolen what do you do? There are things you should have done in advance - before you lost it or it was stolen - and some things to do after the fact. Here are some suggestions:
