HOW TO MAKE YOUR MOBILE PHONE NUMBER UNRECHABLE (S40 USERS)

Sometimes we dont want to receive calls at a particular time.
And it would also be unusual to switch off your phone.
So make your phone unreachable & the caller will thought that its a network problem.
No need of removing sim card!

Lets start. Go to Menu> Settings> Phone> Operator selection> Manual.
Now your phone will search for available operators.
Select any other network except your own network (i.e. If your are using Airtel, select mtn ng or glo in). You'll get an error message 'No network access'. Now look at the signal bar. It is empty! But dont press back. If you press back, the phone will capture signal again. If any caller call you then, he will hear that your phone is out of network range!
This trick works on almost every nokia s40 handset.

Enjoy........
