The update, which has been applied to the Android Device Manager web console as well as the latest version (1.3.8 for those playing at home) of the Android Device Manager application, now gives you the option to add a ‘Call me back’ option to your phones lock-screen once you remotely lock your device.
In the Android Device Manager App, from the ‘Lock’ option, you’re now presented with an option to enter a phone number. Simply fill in an alternate phone number — Note: Don’t put your mobile # here — and a button with the option to call will be displayed on your screen when you select lock from either a friends Android device or the web console. This is now also presented when you try to lock a phone from the web console

If you haven’t set up Android Device Manager on your phone, you really should just in case.
