What is the best anti-theft system for a smart phone?

Now thieving Smartphone is very common all over the globe. So I want to add an anti-theft on my new smart phone. My friend bought an anti-theft system from Shopguard Canada. He suggests me to visit this website (www.shopsecurity.info) and order. Is it better for me? Anyone know about that company?

Anti theft is an important element of Mobile Security. It remotely recovers your device if it is mislaid, lost or stolen. The anti-theft feature enables you to get the location of your device even if its SIM card is changed. You can also make the device sound a loud alarm, take a photograph of the possessor, lock it to prevent unauthorized access and remotely wipe it of all your confidential data-including any files stored on your memory card.
