Due to their small size mobile devices are very vulnerable to get stolen, but fear not there are many anti-theft utilities available for various mobile-phones letting you track and recover your stolen device similar to laptop theft-tracking utilities.
Luckily if you are using Apple iPhone you can not only track your device location but also remote control it, thanks to iLocalis - the best theft-tracking and remote control utility for Apple iPhone.
With iLocalis installed on your device you can keep track of device current location, share location with friends, remote control iPhone, create and restore remote backups, remotely wipe your device data, receive automatic SMS to a pre-configured number of choice if phone SIM is changed (for receiving thief's number and current location), prevent iTunes connection and restore when the iPhone is remotely locked, make remote phone calls and SMS, activate call forwarding remotely (comes very handy if you forget your iPhone and want to forward calls to another number).
