Cell Phones: Know Your Serial NumberHere's how to find your cell phone's serial number:
- Type in the following on your phone: star-pound-zero-six-pound (* # 0 6 #).
- A fifteen digit code will appear on the screen — this is your phone's serial number.
- Write it down and keep it safe.
If your cell phone is stolen, call your service provider and give them this number. They will be able to block your phone so even if the thief changes the SIM card, your phone will be totally useless - no calls, no downloads.
