You going to pay the bill for that? You might get text messages for dirt cheap, but the phone companies charge a whole lot more for commercial use of these systems. (I'm sure it's still pretty cheap, though.) Stupidest security backup in the world, if you ask me. If you're really going to target hack someone, it's just as easy to steal their phone, too. Make sure you use a secure email with an unique password and it should never be an issue. (Even Microsoft or Yahoo is secure if you practice safe Net surfing.)
