Stop a Cell-phone Stealer from Using your Cell Phone
If someone steals your cellphone, the very least you can do is stop the cell-phone user from using it. The logical answer to do that is to call your cell phone company (with a landline or something).
This option presents an obvious flaw. What happens if they change the SIM card? The answer is quite simple.
Dial *#06# on your cellphone. (That was star, pound, zero, six, pound). Without hitting the call button, wait for a few seconds and your phone will display a fifteen-digit number on your screen.
That number is your unique cell phone number. That number is just like snowflakes; it is one of a kind.
Call your cell phone company the next time somebody steals your cell phone and tell them your unique number. They should be able to disable your cell phone so that no matter what SIM is inserted, it will not work.
I haven’t tried the tip myself (I never let my phone out of sight), but it is supposed to work. Give it a shot and write it down. Who knows?
