Block Incoming and outgoing call using a simple code

Call service block :

Mobile is a essential part of life. you cant move without it. we don't use  a mobile to only do  a call or receive, there are many features of mobile that help your daily work more easier such as..reading book, calculator, net browsing etc. When you are in your boss room or a meeting in office or a temple , are you gonna put your mobile on ? Of course not.  another thing at night you can use it for using other features rather switch off the incoming and outgoing call.
here is the solution you are looking for. but its only the system that work in Grameenphone
. you just put some code by typing in your mobile phone.

To off the incoming call just press = *35*0000# , to activate the normal mode again, press=  #35*0000#
To off the outgoing call just press =  *33*0000#, to activate the normal mode again, press=  #33*0000#
happy networking.

thank you.
