How to Make Your Phone Unreachable [TUT]

Hallo frnds,
There are time when someone is calling and you just don't wanna talk. You either don't pick up or switch off your phone.
Ofcourse he/she will come to know that you have done it purposely. So how to make it look genuine? Simple! Just make your phone unreachable.

After applying this trick, when the other person calls your phone, he/she will hear the message "The number you are trying to reach is not reachable. Please try again later". Isn't that great? Doesn't make you look like the bad guy ..Ohk so lets start:

On your phone goto:
> Settings
> Phone
> Operator Selection
> Manual

It will search. Might take a little time (say about 20-30 seconds)

Then a list of operators will come. Choose any operator but not your same one.
Meaning if you are Vodafone, choose Idea or Airtel or Docomo or any but not Vodafone.

Now take a look at the signal bar. It will be EMPTY!

Don't press back. The signal will come back again.
Call from another mobile to your number to test. :D
