I  tried them all. It works even in PR. Enter all these numbers.

 4  Things you might not have known about your  Cell  Phone:

FIRST   (Emergency)

The Emergency Number  worldwide for  Mobile  is 112. If you find yourself out of the coverage area of your mobile network and there is  an Emergency, dial 112 and the mobile will search any existing  network to establish the emergency number for you, and  interestingly, this number 112 can be dialed even if the  keypad is locked. Try it out.

SECOND   (Hidden   Battery  Power)

Imagine your cell  battery is very low. To activate, press the keys *3370#. Your  cell phone will restart with this reserve and the instrument   will show a 50% increase in battery. This reserve will get  charged when you charge your cell phone next time.

THIRD   (How to disable a STOLEN  mobile phone? )

To check your Mobile  phone’s serial number, key in the following Digits on your  phone: *#06# .

A 15-digit code will  appear on the screen. This number is unique to your handset.  Write it down and keep it somewhere safe.  If your phone is  stolen, you can phone your service provider and give them this  code. They will then be able to block your handset so even if the thief changes the SIM card, your phone will be totally  useless. You probably won’t get your phone back, but at least  you know that whoever stole it can’t use/sell it either. If  everybody does this, there would be no point in people  stealing mobile phones.

And  Finally….

FORTH   (Free Directory Service  for Cells)

Cell phone companies  are charging us $1.00 to $1.75 or more for 411 information  calls when they don’t have to. Most of us do not carry a telephone directory in our vehicle, which makes this situation  even more of a problem.

When you need to use the 411  information option, simply dial:  (800)  FREE411   or  (800)  373-3411   without incurring any  charge at all.  Program this into your cell phone now.
